IBM Decision Optimization
In an article in today's Wall Street Journal with the same title as this post, the authors argue that the economic conditions in this recovery are going to be different than the years prior to the recession. Specifically, they mention that capital is going to be much more expense to come by; globalization will continue to put pressure on margins, and rising world demand will drive up commodity costs.
A key part of the article argues that companies will have to learn to finance their growth and investments with their own cash flow.
We are seeing how companies are now adjusting to this reality:
More companies are implementing advanced inventory optimization to reduce inventory to free up working capital for other parts of the business. And, this is not a one-time exercise. These firms are making inventory reduction an on-going part of the business. Our inventory optimization solutions are allowing firms to uncover new strategies to reduce inventory and allow them to maintain optimal inventory levels by integrating this technology with their ERP systems.

In a recent article in Manufacturing Business Technology, the authors noted that IBM was "just as excited" about talking about the broader integration of the supply chain applications within IBM as the new functionality in LogicNet Plus XE and Plant PowerOps:
Our clients are already starting to see value from our integration into IBM as these possibilities become reality. For example, clients are seeing value from the following:
It is exciting to see our supply chain clients get much more value from our tools and services by mixing them with the tools and services from IBM. This is all a great fit with IBM's new initiative to create smarter supply chains.
This blog has often commented on the price of oil. Oil prices have a big impact on the supply chain. As oil prices change, it impacts the cost of raw materials, productions, and transportation. The change in these costs impacts the trade-offs that a firm needs to make.
For example, as the increase in oil prices drives up transportation costs, it can change where product should be made, the mode of transportation used, and the inventory strategy.
Several years ago during the big run up in oil prices, we wrote an article for The Wall Street Journal that discussed how the supply chain strategies needed to adjust to the new prices. As oil prices fell, we wrote an reminder that it was still important to analyze the impact on the supply chain. In both cases, it is important to understand the trade-offs between transportation costs, sourcing decisions, and inventory and adjust the supply chain accordingly.
As oil hit $100 a barrel this week, it is worth recalling these lessons. More firms have invested in more flexible operations, but the basic lessons remain. It is important to adjust your supply chain to fit the realities of the market.
IBM just released a new white paper: "Managing Volatility Through Smart Inventory Planning."
The white paper discusses major trends in the consumer products industry and the impact on supply chains. The paper shows how inventory optimization can help a firm deal with these trends and this is highlighted by various case studies. Here is a quote from one of the case studies showing the value of inventory optimization:
"When we went fully operational with the tool," recalls the manager, "we got a two-day improvement [in days on-hand of inventory]. From a working capital perspective, that's a $5 million savings."
We'll have more on this important paper shortly. If you would like a copy of it, please let us know.

At Smarter Supply Chains – Atlanta Regional Conference, Ronan O'Donovan, product manager with IBM ILOG Supply Chain Applications, spoke about "smarter" inventory and product flow optimization.
Key findings: The challenges around inventory management and product flow are not getting any less. Retail and distribution clients, for example, are requiring a product that optimizes both safety stocks and the flow of products to minimize total supply chain costs.
To juggle all the factors impacting inventory and product flow, companies must make inventory and product flow optimization a formal business process within organizations, front and center and part of the regular monthly planning process, e.g., Sales & Operations Planning (S&OP) or Sales, Inventory and Operations Planning (SI&OP). "Making up the numbers" is no longer acceptable as a planning method.
In addition, processes are moving from "strategic" to "tactical," meaning that planning is becoming an increasingly frequent exercise as companies look to be more responsive to the evolving environment. Companies need to understand, at any given moment, what's the best plan for me right now, given the current set of constraints we're facing.
Ronan discussed typical user workflows and roles for Inventory Optimization, breaking down the separate approaches used by typical Super Users (collecting/managing data), Business Analysts (running what-if scenarios, setting new inventory targets) and Manager Reviewers (reviewing exceptions/alerts, approving/overriding recommendations, tracking planned vs. actual and other KPIs, and reporting). The key to a successful process is not necessarily how each of these classes of users performs their job, but how these users interact through a consistent, closely aligned process.
Where organizations put optimization at the heart of the process, the technology tends to follow to enable that process. Note that this process will evolve and mature over time within a company, as the company learns which factors to incorporate and how best to incorporate them. Ultimately, optimization will never be an "easy button" that will make everything work automagically, but it's a necessary and critical process.
If you are going to be at SCOPE East in Orlando in April (17-19), 3M and IBM will be doing a talk. And, the IBM supply chain group will have a booth at the event--- we will be under the Sterling booth.
Here is a description of the talk:
"Applying Supply Chain Analytics: Benefits of a Central Group"
This talk addresses the value firms can achieve by deploying advanced supply chain analytics and how a group should be structured. We will use case studies and recent events (like the run up in oil prices) to highlight the value from analytics such as network and inventory optimization. 3M will discuss how they are organized to deploy this capability.

This map shows a classic network design case. This client was producing most of its product in northwest Mexico with some product coming from the Virginia plant.
Like many firms, they were just distributing product from the plant where the product was made. The baseline map shows the current situation.
They wanted to do an analysis to determine a better distribution strategy. The result on the right shows the optimal distribution strategy. Thy shipped full trucks loads from the plant in Mexico to the warehouse in Virginia and then on to the customer.
This solution has much more expense in transportation from the plant to the warehouse. However, this is more than offset by the savings on shipments to customers. The optimal solution resulted in $5MM in savings (about a 25% reduction in transportation costs).
Although this case looks rather simple, it wasn't clear at the start whether the best solution would have one warehouse in the center of the country, two warehouses not located at the plants, or a third warehouse. And, it wasn't clear how the country should be split. And, finally, with a lot at stake in terms of savings, and moving capabilities, it is important to do a robust study to make sure you have covered all the angles.
Kurt Zetah with Dow Chemical provided this presentation. Kurt is Network Optimization leader and Mergers and Acquisitions leader for Dow's Supply Chain. Dow has 200 manufacturing sites in 38 countries, with $54 billion in sales and 46,000 employees, serving customers in 160 countries.
Dow began supply chain modeling in the 1980s, using linear modes with regard to feedstock selection and, to a limited extent, customer sourcing. They moved into production planning and distribution center planning in the 1990s using statistical modeling; into sophisticated sourcing analysis in the 2000s with mixed integer modeling; and into stochastic models today. Back in the 1980s and 1990s, the data collection was largely manual, but as they have become more integrated from a systems perspective, they have been able to reduce modeling time from months to days or even hours now. But they want to become even faster to be able to respond to rapid changes in raw material, transportation and other costs. This is in recognition of the fact that supply chain costs have become increasingly important – and increasingly recognized as important within the company.
In summary, Kurt noted that modeling is a requirement to compete today – "If you're not doing modeling, sell your stock in your company." You need to be able to model faster and more accurately, and you have to institutionalize the process to ensure success over time.

Finding good routes can reduce transportation costs by 5-15%.
Finding great routes can reduce costs by a further 5-10%.
These savings can add up fast.
However, finding these great routes can be difficult.
On one level, routing seems trivial. If you have 75 shipments to make, you can easily look at a map and come up with routes. If analyze the routes, you can probably make changes to reduce costs. But, how do you know if you've found good solution? How do you know if you've found a great solution?
What is not obvious at first glance is how many total possible routes exist in a routing problem. In a problem with just 75 shipments, if you allow up to 10 stops per truck, the total possible routes exceed 10 to the 100th power (10 followed by 100 zeros)! Even with today's computing power, there is no way to evaluate each of these options.
And, the problem becomes harder when you consider delivery windows, different types of trucks, the ability to do backhauls, making making multiple trips with the same vehicle, and so on.
This is where IBM's optimization expertise comes in. Both the IBM ILOG Transportation Analyst and Sterling TMS use the ILOG CPLEX Optimizer to find great routes. The ILOG CPLEX Optimizer product contains a module for Constraint Programming (CP). CP is well suited for tough scheduling and routing problems, especially routing problems with time windows. It is this optimization technology that allows to you to find great solutions.

This event will be very educational with deep dives into:
There is a strong track for those interested in the supply chain. But, IBM is strong in other new areas that eventually (if not already) will impact the supply chain. For example, companies need to react to the proliferation of data on customers, the consumers greater user of smart phones, and the rising importance of social media. These topics will all eventually impact managers in the supply chain. This event will help you understand and get out in front of these trends.

At Smarter Supply Chains – Atlanta Regional Conference, David Simchi-Levi talked about Combating Volatility through Flexibility. I talked about this in greater detail here.
One point that David raised at the outset was the increased level of volatility surrounding the supply chain. His point was that companies need to be careful in thinking about the "best practices" that they apply to managing their supply chains. In such a dynamic environment, the best practices that applied before the recession - or before oil prices spiked, or before they crashed again - are not necessarily applicable today. It's a call to action for all supply chain executives to step back and reassess their processes to see if they are still "best in class," or whether there might be benefit to adjusting to the "New Normal."

Accenture-ILOG Webcast: Past the Tipping Point: Record Oil Prices Require New Supply Chain Strategies
aeortiz 2700024WMF Tags:  network design and planni... supply chain webcasts inventory optimization 2,406 Views
Accenture and ILOG will host the 4th in a series of collaborative webcasts on green logistics and sustainability issues. Previous webcasts focused on carbon footprint reduction initiatives and best practices. The November 3rd webcast will bring an additional level of complexity to the mix: fuel price. This webcast is based on the September 22, 2008 Wall Street Journal publication, Crude Calculations.
Date: Monday, November 3rd
Time: 10:00am CT
Abstract: In many respects, fuel costs are the “universal influencer” of business strategy and activity. There is no end of consequences for companies that import, export, ship or manufacture goods. Even companies that just consume indirect or MRO materials are affected, as are retailers and other direct-to-consumer entities. Further complicating the issue is fuel cost's unpredictability. There is no way to know where the top of the price-rise spectrum is or whether prices might even fall in the near or not-so-near future.
But even if we can’t know the future, companies can’t afford to do nothing. The consequences are too extreme. And the likelihood is too high that competitors will respond creatively to gain a competitive edge over those that are slow to react. Scores of supply chain functions must take action. An overview of five such functions— network strategy; sourcing and procurement; planning and forecasting; transportation and distribution – will be discussed in this webcast.
Our goal is to provide a high-level overview of how higher fuel prices affect each function, how the function must change as a result, and what specific things supply chain leaders must do now.

Last week, IBM hosted another Connect to Win event for business partners at it's northern California IBM Innovation Center. The event focused on business analytics and featured IBM Distinguished Engineer Jeff Jonas, a dynamic and highly sought after speaker. Among his many accomplishments, he is known for developing the technology used by the Las Vegas gaming industry featured in the book "Bringing Down the House", the recent movie "21", and numerous documentaries on the Discovery Channel, Learning Channel and the Travel Channel.
Following the keynote by Jeff Jonas, IBM hosted a panel discussion. Some 30+ partners came to learn how to leverage analytics in their offerings, and naturally a wide spectrum of analytics sophistication was represented, generating a vibrant discussion on everything from Smarter Planet to Artificial Intelligence to Decision Management.
The panel was made up of:
During the panel discussion I had the opportunity to first share IBM's vision for business analytics, using an adaptation from Tom Davenport's book "Competing on Analytics", to explain why, how and where IBM has invested $14B since 2005 in business analytics. Several partners thanked me afterwards for presenting this visual, as it provided them with a blueprint for how they might evolve their own analytics capabilities.
In fact, this gave me an opportunity to define a new software category for many - Advanced Analytics, which applies statistical and mathematical techniques to provide forward-looking capabilities, beyond the insight commonly extracted from historical data and information. It can be viewed as a subset of Business Analytics, and provides an interesting convergence opportunity, between the IT-based "analytics" world, and this emerging world previously reserved for specialists in statistics and Operations Research-related disciplines (Management Science, Industrial Engineering, Financial Engineering, Systems Engineering, Applied Mathematics, etc.). As the business world evolves its analytics agenda beyond business intelligence and performance management capabilities, the desire to not only look back in time, but forward in time as well, is driving awareness for Advanced Analytics - and creating many opportunities for SPSS and ILOG Optimization at the point of business impact.
To learn more about Advanced Analytics for a Smarter Planet, start here:

In a recent conversation with AGRANA, a large sugar, starch, and fruit company based in Europe, we were reminded of the value of network design on an on-going basis.
AGRANA reports using LogicNet Plus both for strategic network design studies impacting the next 1-2 years, but also for the day-to-day issues that come up. These kind of daily studies can be done in the context of the full model or as simple stand alone models.
This daily use of network modeling helps a firm keep on top of its supply chain to continuously control and minimize costs or improve service.
AGRANA reported on the aspects of LogicNet Plus that makes all this possible:
Interestingly, this use of LogicNet Plus fits with IBM's Smarter Planet initiative: helping firms make better decisions with the data they have and providing tools that allow firms to do this faster and easier.

I attended the CSCMP Chicago Roundtable event at RR Donnelley last week (February 11, 2009) and heard an interesting presentation by my colleague Jay Jayaraman. He discussed a project we are working on where a manufacturer of a commodity has the choice of exchanging product with a competitor. The idea is that a company can source an order from a competitor’s location that is closer to the intended customer than its current manufacturing base. The impetus being a saving on transportation costs. The key is that both companies can benefit from the swap since they both can reduce transportation costs, and each company keeps their relationships with their customers. Of course, this scenario can only work with commodity-type products.
To take full advantage of the situation, our network modeling and production planning tool, LogicNet Plus XE, can be used to determine the best possible swaps as well as understand all the constraints that impact the results. Doing this type of analysis with Excel can lead to omissions and sub-optimization.
It’s fascinating how collaboration, even amongst “enemies”, can lead to benefits for all…

The first presentation of the day came from Karen Butner, Global Supply Chain Management Leader for the IBM Institute for Business Value, on IBM's Global Chief Supply Chain Officer Study, based on interviews with 400 some supply chain executives worldwide. Karen Butner has more than 25 years of experience in supply chain management business practices and strategies. Her concentration has been to assist clients in the high technology, retail and consumer products, electronics, and transportation logistics industries develop strategies and improvement agendas to bring significant value in transforming their global supply chain performance.
The study took about six months to get through, with conversations (hour-and-a-half interviews) with 400 supply chain leaders in about 30 different industries across 25 counties, and they spoke with a variety of different supply chain executives within the enterprise. They focused on supply chain strategy; how companies are collaborating; how agile companies are; how they manage risk; how they use technology and leverage opportunities around real-time data management. One key focus was on how effective different supply chain initiatives are.
The top challenge cited by Chief Supply Chain Officers was supply chain visibility, and where they are focusing is on real-time information transparency inside and outside the enterprise, as well as on event management and alert notification. Interestingly, the top barriers to greater visibility were "organizational silos" and people are "too busy to assist others" in collecting the data and information necessary to provide visibility.

Recently, a member of Bayer’s Supply Chain Optimization team spoke on how to create a greener supply chain. It was stressed that the carbon emissions were only one part of the equation. The analysis had to include other factors such as taxes, exchange rates, oil prices, sourcing, service time, and, of course, costs.
As an example, a project in China is mentioned for the pharmaceutical products: Previously, the supply chain strategy relied on air freight. After many different scenarios were tested, Bayer found a solution with 3 DC’s that reduced lead times, reduced carbon emissions, and kept costs neutral.
Besides projects in Asia and Japan, the Bayer team has used the tool in the US and Europe.
It was stressed that all of these projects are complex and involve careful analysis of the trade-offs.
In fact, it was mentioned that “some questions you want to raise can’t be answered without a tool like LogicNet Plus.”
Please contact us if you would like more details on this case.

David Simchi-Levi talked about volatility and flexibility in the supply chain, putting a definition around those terms, and trying to quantify the impact of flexibility, as a foundation for helping companies understand how they can invest in flexibility in their supply chains.
David noted the IBM ILOG supply chain applications, which include Strategic Supply Chain Design & Planning (LogicNet Plus, LNP; Inventory Analyst, IA; Product Flow Optimizer, PFO; Transportation Analyst, TA); as well as more tactical-level planning, e.g., for safety-stock setting for ERP (Inventory Planning); and Production Planning and Detailed Scheduling (Plant PowerOps, PPO).
Today's supply chain challenges are well known: global supply chains with long lead times, combined with rising and shifting customer expectations. In addition, as global manufacturing costs rise in different regions (increasing labor costs, e.g., in China by about 20% annually over the past five years versus 3% in U.S.), the optimal supply chain five years ago may longer be applicable.
Logistics costs also have been increasing as a percentage of cost of goods sold, rising 15% as a percentage of GDP in the U.S. from 2003 through 2007with rising oil costs, rail capacity pressure, truck driver shortages and security requirements. Transportation costs have increased 47 percent in the last five years, but inventory costs have also increased, by 62 percent in the same time period, e.g., due to longer supply chains (more inventory in motion and more safety stock to meet more demanding customers). David also noted that one strategy that companies have used in the face of higher transportation costs, larger shipment sizes (to take advantage of economies of scale), have had the effect of increasing inventory costs.
Risk levels have increased in the supply chain, a result of successful implementations of Lean, outsourcing and offshoring. Lean supply chains make it more difficult to meet high service levels with less inventory, while outsourcing/offshoring creates more opportunity for disruption in the supply chain. Sustainability also has become more important - less so as oil prices have declined, but that is likely to change as oil prices increase again. At the same time, the supply chain has seen unprecedented levels of volatility, e.g, as a result of commodity price volatility (e.g., high volatility in price of oil in 2008, with 39 days when the price of oil changed 5 percent or more from its previous day close).
David posited that flexibility is one of the top supply chain capabilities in which companies can invest to increase their ability to respond to all the above challenges. Flexibility is the ability to respond to change, e.g., demand volume or mix, labor cost, exchange rates. The objective is to reduce costs and reduce the amount of unsatisfied demand and improve capacity utilization, with no or little penalty on the service-level side. Flexibility can be achieved through Product Design (a focus in the high-tech industry, especially, e.g., a modular, Dell-like product architecture, standardization, postponement, substitution); Process Design (e.g., flexible work force, Lean, flexible contracts [e.g., options contracts], outsourcing, dual sourcing); or System Design (e.g., capacity redundancy, manufacturing strategy, distribution strategy).
Focusing on System Design, David looked at an example focusing on balancing transportation and manufacturing costs, coping with high forecast error and utilizing resources more effectively. The goal is to achieve all (or most of) the benefits of "full flexibility" with a small investment that provides a small level of flexibility. David ran through two case studies of flexibility.
The first case study focused on a manufacturer in the food and beverage industry. Initially, the company employed a dedicated manufacturing strategy, with each product family manufactured in one of five domestic plants, and manufacturing capacity was in place to target 90 percent line efficiency for projected demand. The company had five manufacturing plants with varying average labor costs, and eight DC locations. The company was focused around manufacturing costs, e.g., by producing high-volume product in its lowest-cost facility. To analyze the benefits of adding manufacturing flexibility to the network, the company analyzed scenarios that provided for varying degrees of manufacturing flexibility, up to full flexibility, where each plant could produce each product line, and everything in between. An analysis of plant to warehouse shipping costs showed, of course, that full flexibility produced lower transportation costs, but an analysis of the impact on total supply chain costs showed that just investing in a little more flexibility (by adding flexibility at all plants to produce two product lines) produced 80 percent of the benefits of flexibility with less impact on manufacturing costs, while avoiding the higher costs of investing in full flexibility (ability to produce all five product lines at each plant). But the company also wanted to understand the impact of potential changes in demand volume, so they considered three different scenarios based on growth for different product lines. In each case, adding the minimal level of flexibility outperformed the baseline and even "full flexibility" in terms of KPIs like demand satisfied, shortfalls, cost/unit and average plant utilization.
In further analyzing the benefits of adding a small amount of flexibility, David noted that in the above example, the full benefits of what he calls "2 flexibility" (ability to have each plant product two product lines) are possible when there is a "long chain" that connects all the plants in the company's network, such that a change up or down in demand for a given product will not cause a disruption in the company's ability to meet that demand. This example requires much more in-depth explanation that is possible here, but I hope to be able to write about this phenomenon later.
David also ran through a case study of optimizing S&OP at a bottling company operating 57 plants in the U.S. and 103 plants worldwide, driving 240,000 miles a day to meet customer demand. Implementing the flexibility described above, the company created a process that brought together sales, supply chain, marketing, manufacturing in collaborative planning process. Results: The company reduced raw materials and supplier inventory from $201 million to $195 million; saw a 2 percent decline in the growth of transport miles even as revenue grew; and added 12.3 million cases available to be sold due to reduction in warehouse out-of-stocks, adding up to the equivalent of adding 1.5 production lines without actually any investment in plant.
David also spoke about redundancy in the supply chain and the challenges and benefits of scenario analysis for optimizing a supply chain network and setting supply chain strategy. He discussed a case study involving a manufacturer of consumer packaged goods. The company had 40 manufacturing facilities, but was looking to rationalize its plants while also managing risks in its supply chain. The company looked at how many plants they could close without impacting their ability to meet demand and came up with a plan to close several plants that would result in savings of $40 million to the bottom line. However, this plan left plants very distant from customers, resulting in a higher lead times. In addition, the attendant higher levels of plant utilization left the supply chain exposed to higher levels of risk from disruptions. The challenge for the company was to build into the model scenarios that take into account different sources and levels of risk, based on the number of plants that the company ultimately would decide to maintain. David noted that the optimal solution in terms of total supply chain cost was not necessarily the optimal solution in terms of risk management. He pointed out that total supply chain cost is invariably "flat" around the optimal strategy, so the company could look at closing a fewer number of plants than the "most optimal" solution in order to mitigate risk.So, in summary, a small amount of flexibility can often provide large benefits, supply chain costs are flat around the optimal strategy, and positioning inventory effectively can make a big impact through taking advantage of risk pooling.

Do you need to reevaluate your supply chain?
The Q3 2011 edition of CSCMP's Supply Chain Quarterly has an article on the seven signs that you need to redesign your supply chain. (click here for a link to the article-- you need to be a CSCMP member or subscribe to the journal.) The article was written by Simon Bragg, Richard Stone, and Julian Van Geersdaele of the consulting firm SCI3. [UPDATE: Click here for a link to the article on SCI3's website]
The article provides a great overview on why network modeling is important to a firm.
They make the point that network modeling tools can help you evaluate many different strategies to understand the impact of each. IBM's new capability to optimize over multiple user-defined objectives greatly enhances this process. That is, you can gain deeper insight into your supply chain by evaluating the complete trade-off curve between multiple objectives.
Also, the article points to many reasons for re-evaluating your supply chain that reinforce the need for bringing these types of tools in-house. For example, it is important that you have the on-going capability to analyze service failures, major disruptions, product and customers changes, and changing 3PL relationships. You do not want to wait every two to four years to look at these issues, you want to be on top of them on an on-going basis.

In a previous post, we mentioned David Simchi-Levi's new book, Operations Rules. We've received a lot of questions about the book and the concepts.
Now, the official website for the book is up and running. Click here for the link.
The website highlights why the concepts from the book are important. For example, Jim Champy, the coauthor of Reengineering the Corporation says:
"Companies today are faced with an increasing number of choices in operational and supply chain strategies. This book goes beyond just showing how to make the right operational decisions. It makes the critical link between operations and providing more value to customers. It's a must read for anyone involved in operations and strategy."
Also, a key concept discussed is the fact that many companies offer different value propositions through different channels or brands. These different value propositions imply that the company may have different supply chains. However, the company cannot simply operate their supply chains separately. They need to take advantage of synergies where it makes sense. Click on the S&OP video in this link for more information

Optimization in and of itself is nothing new but it is
often overlooked by Line of Business and Information Technology
professionals since many instances of it are embedded inside "classic
supply chain management applications". Optimization allows companies to
make sense of the massive amounts of data across the extended
enterprise. By applying this data in unique and innovative ways, firms
can optimize business outcomes by anticipating, controlling and adapting
to a dynamically changing and chaotic environment, using the insights
from visibility, analytics and trading partner collaboration to direct
and control operations more intelligently.
With the advent of "Optimization 3.0", firms now have the ability to layer or integrate key advanced analytics technology on top of existing supply chain planning and execution systems to support both long-term (strategic) and short-term (tactical) planning goals as well as detailed scheduling while continuously improving operational efficiency, reducing costs and ultimately enhancing the overall customer fulfillment experience. This new combination of State-of-the-Art advanced analytics and B2B integration gives businesses the unprecedented ability to quickly model and solve across the most complex systems and implement solutions in near real-time, creating truly adaptive supply chains.

After the break, we heard from Ben Fuqua, vice president of the management and supply chain consulting team within TranSystems Corporation.
In his presentation, Ben discussed the impact of the dynamic transportation environment, with case studies reviewing impacts on infrastructure and shippers. One theme that echoed David Simchi-Levi's presentation: Green can be compatible with efficient distribution.
Ben noted that the transportation industry is in transition, and supply chains are having to deal with rising transportation/logistics costs. Costs are being driven by, among other things, higher fuel costs and new fees envisioned for containers coming through ports. Volume is shifting between ports (e.g., increased traffic through East Coast ports), trucking bankruptcies are increasing, rail companies are investing in capacity, use of intermodal is increasing.
Against this backdrop, what are companies changing in how they operate in this environment? How are they balancing supply chain costs with customer-service levels? Ben presented case studies of companies balancing these issues, including a toy manufacturer, a home furnishings wholesaler, a durable goods manufacturer and a beverage manufacturer (see Ben's slides from his presentation on the Symposium Web site – the slides are due to be posted by the end of the Symposium on Friday). Lessons learned: each company's optimal network is going to be different, depending on their business model, but you won't be able to understand whether you have the optimal solution without going through the modeling process. And modeling can help you come up with a flexible solution that is going to help your supply chain adapt to the coming changes as the transportation industry continues to be in transition.
The day began with a presentation by Filippo Focacci, product manager for ILOG's planning and scheduling solution, ILOG Plant PowerOps (PPO). His presentation, "Factory Scheduling in the Food & Beverage and Pharmaceutical Industries" focused challenges, solutions and lean initiatives in these process industries.
Companies in this space face high demand variability, complex manufacturing processes, a focus on performance management and cost control, product mix changes and new product introductions/phase outs, and complex product quality issues. ILOG's PPO is designed to model key manufacturing constraints and to be used as a decision support system. Its strength is its optimization and performance analysis. It's not intended to replace current IT infrastructure but to augment it through integration with existing systems.
Filippo first covered an example from the fresh dairy industry, which moves its products from the cow through pasteurizers and fermentation, into storage and filling lines, into the finished product. The industry faces lengthy – up to day-long – cleaning-in-place cycles for its equipment, and these cycles are key to the industries process and are triggered by certain events (e.g., equipment sits idle for eight hours). Companies in the industry face high-demand variability, short shelf life of intermediate products and finished products, and relatively long lead times of three to four days. From a manufacturing efficiency point of view, companies in this space are looking to maximize resource utilization while minimizing waste and maximizing manufacturing predictability. Quality is a key issue, too, of course.
The company in question is using PPO for integrated planning and scheduling to find the right tradeoffs between scheduling goals (efficiency, changeover costs, etc.) and supply chain goals (e.g., balancing min/max days of supply). The tool lets the company also balance finished product and intermediate product planning. Planners can run various scenarios based on different constraints or goals and compare select KPIs across the scenarios. Benefits include the ability to have manufacturing and supply chain using the same tool. The tool let the company move from once-a-week planning to daily planning, improving their agility as a company. They saw 50 percent reduction in product waste and improvements in operational efficiency. The company rolled the tool out in Mexico, then Russia, then Argentina, which had fast-growing markets and were therefore both good case examples for the company and markets where increased efficiency could lead to greater sales and, ultimately, market share.
Filippo also ran through an example in the pharmaceutical industry and one that touched on the implementation of Lean within an enterprise.
Filippo talked about a scheduling requirement trend: While planners are looking for tools that better take into account manufacturing and supply chain reality, engineers want tools that generate more realistic plans. He suggested that using a tool like PPO lets both constituencies work off the same set of data.
Biotech manufacturing is an emerging industry. It combines pharmaceutical challenges such as heavy regulation and high production costs with the very specific challenges derived from biological manufacturing processes such as complex manufacturing operations and high process variability. These challenges lead to a strong focus on plant design and process design as well as on manufacturing operations. Industrial engineers working on plant and process design look for the optimal configuration of equipment, process operations and biotech technologies. Manufacturing planners need to make sure that the manufacturing process runs smoothly and is able to meet business requirements. In both cases, factory scheduling turns out to be a key technology that helps both planners and industrial engineers meet their goals.
To learn more about this topic register for the ILOG webcast, Factory Scheduling in Pharma/Biotech: from plant design to manufacturing, on Friday, October 10th at 10amCT.
Fidelitone Logistics recently announced that they are using LogicNet Plus XE to help analyze their customer's supply chains. They state that they can help remove 15-20% of costs:
"Based on customer order data, we were able to use ILOG to run several scenarios and analyze the geographic impact multiple locations would have on service and cost," explained Chuck Perry, director of customer solutions for Fidelitone. "This fact-based analysis shifted the client's assumptions and created a 15-20 percent reduction in cost for them. Additionally, the fact-based nature of the analysis enables us to be more competitive with pricing as our confidence level in the analysis has proven true with each application of the technology."Here is a link the press release picked up by Supply and Demand Chain Executive.

It is often difficult to explain how difficult it is to come up with an optimal solution to a vehicle routing problem.
I am convinced that part of the problem is that it is so trivial to come up with feasible solutions to a vehicle routing problem: just send out a truck to make every stop or group stops and send a truck to make multiple stops. And, an experienced dispatcher can often quickly improve upon a given schedule by looking at the routes. And, what we've found in practice, the constraints that would make the problem harder (like deliver time windows) are often simply ignored.
However, being about to find a solution to the problem (and maybe even an infeasible one), is not good enough. We've found that using advanced optimization can lead to routes that shave 5-15% of costs (on routes that are already deemed pretty good) and meet all the constraints.
What makes this interesting, is that the optimization is actually very difficult. Mike Trick's recent blog post highlights some of the difficulty with routing by writing about a Traveling Salesman Problem (TSP) a politician might face in Iowa trying to visit all 99 county seats in the shortest amount of drive time. Mike Trick quotes Bill Cook:
For vehicle routing (with multiple vehicles, capacities, time windows, and so on), the story gets more complicated. In a 2009 paper by Gilbert Laporte titled "Fifty Years of Vehicle Routing" discusses the progress that has been made in this field. He mentions that the vehicle routing problem "is considerably more difficult to solve than the TSP." Over fifty years of research has led to significant advances in different approaches and algorithms. But, he mentions that the field still has a long way to go to solve larger (and more realistically sized) problems found in industry.
This mirrors our experience with the ILOG optimization for vehicle routing-- these problems can be mathematically challenging. To solve these problems in practice requires an optimization-based approach. We have been working on this since the mid-90's. Some readers may remember the ILOG routing engine called Dispatcher or the tool Transport PowerOps. This routing engine has found its way into to the product called Transportation Analyst. And, the underlying optimization engines are now part of the CPLEX toolkit.
David F. Carr of Forbes Magazine recently wrote an article based on an interview with Steve Sashihara, the author of the new book called "The Optimization Edge: Reinventing Decision Making to Optimize all of Your Company's Assets".
The article does a great job of explaining how firms need to embed mathematical optimization deep into their organizations to really take advantage of their investment in IT and data.
The article mentions that IBM and IBM's ILOG CPLEX have the ability to address the need for more automated optimization. This article confirms the value we've seen in Optimization:
And the list could go on. We are finding that firms who push optimization deep into their organizations see significant returns on their investment.
As a complement to the Forbes article, we have just released a short educational video to explain the value of mathematical optimization to business leaders. Click here for a link to that video.

In this month's Harvard Business Review (July-August 2009), George Stalk, Jr.'s article points out that global gridlock will force companies to rethink their supply chain strategies or lose out to more forward looking competitors.
His article sites the growing congestion on the highway system, the ports, the railways, and the airports. The impact of this congestion will be an increase in time and variability in the supply chain.
The solutions we offer can help you take time and variability out of your supply chain:
Great New Book by David Simchi-Levi-- Operations Rules: Delivering Customer Value Through Flexible Operations
David Simchi-Levi has a new book coming out in August, 2010, Operations Rules: Delivering Customer Value through Flexible Operations. See the Fall Announcements from MIT Press page 13.
Here is excerpt from the review on the MIT Press website:
Simchi-Levi identifies the crucial element in a company's success: the link between the value it provides its customers and its operations strategies. And, he offers a set of scientifically and empirically based rules that management can follow to achieve a quantum leap in operations performance.
Flexibility, says Simchi-Levi, is the single most important capability that allows firms to innovate their operations and supply chain strategies.
David Simchi-Levi is the founder of LogicTools which is now part of the IBM ILOG Optimization and Supply Chain Solutions group. He is still actively involved in IBM.
This group offers solutions in network optimization, inventory optimization, detailed production scheduling, routing, container optimization, shelf space optimization, and other areas that can help companies implement the ideas from his book.
In another article in this month's Harvard Business Review (July-August 2009), "Management as a Science" was cited as one of the trends executives should watch.
Management as a science uses mathematical models and data from operations to help executives make better decisions. Our supply chain planning applications are a great example of models helping firms make better decisions.
The authors point out that despite some recent failings of some high-profile financial models, the trend towards management as a science will march on. They note that the tools need to become more dynamic, that they need to integrate more real-world feedback, and that "business executives need to get better at using them."
ILOG's supply chain planning applications are well positioned within IBM to help firms take the lead in this trend. Supply chain executives benefit from:
Headlines: "BP Didn't Plan for Major Oili Spill." Do You Have a Contingency Plan for Your Supply Chain?
The coverage of the oil spill in the gulf is starting to focus on BP's lack of a plan in the event of major oil spill.
This reminds us in Supply Chain about the importance of contingency plans. Do you have a back up plan in case something happens in your supply chain? For example, a warehouse, plant, or supplier is no longer available, a port closes, or a border shuts down.
Although problems with the supply chain are hopefully not as globally bad as a major oil spill, it is still important to you and your organization. A supply chain disruption can cause significant loss of revenue, loss of market share, decreased shareholder value, and lost customers. A supply chain disruption is not pleasant for the managers within the firm.
And, it is no longer acceptable to say that you couldn't have foreseen the problem. With modeling tools like LogicNet Plus, leading companies are building and maintaining models of their supply chain. Well in advance, these firms are using the models to develop contingency plans for a wide variety of problems. When something happens, a plan is in place and can quickly be adjusted to meet the needs of the situation. The ease-of-use, robustness, and ability to integrate LogicNet Plus make all this possible.
In one case we are familiar with, a fire at a neighboring plant shut down production. The company was able to quickly determine the best course of action.
A recent article in the Chicago Tribune noted that his holiday buying season was good for retailers. It also noted that good inventory management was part of the success:
Memories of having to take unexpected markdowns of up to 70 percent on leftover holiday merchandise during the recession prompted retailers to keep inventories low during the critical months of November and December. The strategy has helped retailers better manage their businesses, but it also means clearance racks are expected to be thin.
Good inventory optimization are critical to a firm's success. Only by optimizing inventory across the supply chain can you truly optimize inventory within the stores. This often can involve both the retailer and the suppliers jointly optimizing inventory. Proper inventory optimization can give your supply chain the flexibility to meet unexpected high demand with a minimal amount of inventory invested in the system.
As retailers try to continue the momentum of this holiday season, inventory optimization will play a critical role--- too much inventory creates a financial risk if sales do not materialize and too little inventory creates a risk of losing revenue or market share.
