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."
Supply Chain authority Andrew Reese is Editor of Supply & Demand Chain Executive. He has been invited by IBM PR to attend this show as a blogger and speaker. Like all other speakers, Andrew will receive all speaker benefits including travel and board.
Manufacturers are offering more and more products by changing the "sizes, brands, colors, fabrics and flavors."
But, "instead of improving profitability, these tactics often lead to
bloated product portfolios that raise a company's costs, reduce
supply-chain efficiency, confuse consumers and lead to shortages of
The article offers tips for reducing the number of SKUs. But, this problem is difficult to tackle-- it involves many different groups and decisions can impact the top line and ability to compete for shelf space. At IBM, our advanced analytics solutions can add to the analysis.
Cognos helps with the Business Intelligence, allowing you to understand the demand and sales price of each SKU in each market. SPSS allows to determine which SKU's actually sell together and estimate what would happen to overall demand if SKU's were reduced. That is, if you eliminate an SKU, what will be the likely uptick in the demand of the remaining products. ILOG can help determine the true landed cost, supply chain efficiencies, and safety stock impact of a reduced SKU count.
Combined, these technologies could help you make the correct decisions on how many SKU's to eliminate and which new varieties to the market.
This releases enhances LogicNet Plus XE's leadership position in the supply chain network design market. It includes many cutting edge and innovate features that will allow you run new types of optimization , and gain deeper analytical insight. Highlights of the new release include:
Ability to run the optimization with multiple user-defined objectives and automatically build detailed trade-off curves. Traditional network design limits you to one objective. This innovative feature allows you to make better supply chain decisions by weighing multiple objectives.
Detailed Landed Cost reporting and analysis
Lane visualization for easy model building, visual understanding of the structure of your supply chain, and detailed analysis of the output
New interface for improved ease-of-use
Center of Gravity modelling
Stochastic inventory planning
This is the third major release of LogicNet Plus XE since 2009 and shows IBM's continued investment in the product.
An article in DCVelocity provides some great insight into how Whirlpool and Maytag combined their supply chains. Whirlpool purchased Maytag in 2006 and promised the investment community $400M in savings over the first 3 years.
According to the article, $40M of savings per year was going to come from logistics-- freight and warehousing costs. This reminds us how important it is to get these decisions right. And, in Whirlpool's case, the article reported that they were able to overachieve and hit a savings of $66M in the current year.
How they got off to a fast start:
One of the first steps was to determine what inventory was on hand in
both operations so that Whirlpool could determine what to do with it.
The company acquired ILOG's LogicNet Plus suite of network design and
planning software so it would have a tool in place that
could import and crunch data once the deal was finalized (regulations
did not permit the managers to have access to Maytag-specific data until
the acquisition closed).
"When the deal was completed on March 31, 2006, we were in the
starting blocks ready to go. We had our tools in place and people in
place, and we had our own data. We were then prepared to bring in the
The network optimization with LogicNet Plus allowed Whirlpool to determine which distribution centers to close, which new sites should be built, and what the local cross dock network should look like.
We have seen this type of result many times over the years. When a firm grows through an acquisition, having a high-quality network optimization tool allows it develop solid plans for the new network. This creates a foundation for additional improvements and helps a company meet the goals of the acquisition.
A new case study is available highlighting how Johnson Controls uses LogicNet Plus to model and improve their closed-loop battery supply chain.
The following is a quote from Johnson Control's Supply Chain Network Strategy Manager, Chad Montgomery:
"I’m using LNP XE every week to perform modeling on a variety of projects from small capacity analysis/capital investment decisions to quarterly financial forecasting and annual budgeting for capacity utilization, plant manufacturing, and shipping territories. LNP XE has allowed us to create clear pictures of our network, starting with a best-case utopia state and then quantifying the impact of each constraint. This clarity can reveal hidden savings opportunities as well as gives complete insight into the main drivers of our supply chain”
While doing some research for an upcoming white paper, I came across a nice article from Nov 2009 from Dan Gilmore at the SupplyChainDigest, "The Real Value of (Less) Inventory." A key line from the article is:
reducing your level of inventories relative to sales and sales growth
can have a dramatic impact on a company’s share price."
The article quotes research and cases to back up this claim. This certainly fits with what our customers are telling us-- they are seeing significant inventory savings through inventory optimization.
The word "permanent" is a great choice of words. Inventory optimization technology, by itself, will not lead to a permanent reduction. As we noted in an earlier post, we have developed an inventory planning playbook to help firms make the right inventory decisions with the right cadence and considering important strategic factors.
The article shows how the techniques are being applied in a non-discrete manufacturing environment.
We are seeing a similar trend.
However, many firms struggle with translating the lean system developed by Toyota for their environments. This can be especially difficult in long supply chains or in a environment where there is inherent batch or tank processes.
The excellent book by Hopp and Spearmen, Factory Physics, helps translate Toyota's system to other environments by defining lean as:
A manufacturing supply chain is lean if it accomplishes its fundamental objective with minimal buffering costs.
They define three types of buffers a firm can have: inventory, time, or capacity. In short, if you can make your product with a minimum of inventory, short cycle times, and excess capacity, you are getting closer to lean.
We are finding that optimization can be a great way to minimize these buffers and evaluate the trade-offs between them.
With inventory optimization, firms realize that the may not be able to eliminate inventory completely or that they have removed it from the wrong location. In these cases, optimizing inventory is important to achieving a lean operation.
In process manufacturing plants, these firms are relying on high-end optimization to better schedule the plants. They realize that they cannot get around batch and tank production, set-ups, cleaning operations, and other realities in the process industry. Optimization-based scheduling allows them to reduce manufacturing costs, improve inventory, and achieve lean operations.

In a recent webcast, IBM discussed the latest enhancements to IBM ILOG CPLEX Optimization Studio 12.2, from streamlined packaging and licensing, to major performance improvements.
CPLEX Optimization Studio now completely supports the rapid development and deployment of both mathematical programming and constraint programming models from a powerful IDE, based on the Optimization Programming Language (OPL), programmatic APIs, or other 3rd party modeling interfaces via supported connectors (Matlab, Microsoft Excel, etc.).
At the conclusion of the webcast, attendees were asked to identify the feature that excites them most from the latest release. Here are their Top 3:
IBM has once again re-asserted its leadership in mathematical optimization, with a remarkable 2.7x performance improvement on the most challenging optimization problems, mixed integer programs taking at least 1000 seconds. The latest release strengthens IBM ILOG CPLEX Optimizer as the most trusted and widely-deployed solver. Streamlined packaging, and removal of license key enforcement makes it even easier to choose CPLEX. What are your top 3 new features? To view the recorded webcast, please follow this link:
Customer expectations have grown for not only what they are buying
and how they are buying it, but how it is fulfilled and when they will
receive it. They want to buy online and pick up in the store, or have it
shipped direct to their home or office -- and they don't want to wait.
This shift has supply chain professionals moving beyond transactional
enterprise systems and operational rules of thumb to a more advanced
value chain. The value chain takes advantage of all this new granular
customer data to enable organizations to respond to demand variability
at the point of consumption -- connecting the supply chain directly to
customer demand, orchestrating seamlessly between trading partners and
suppliers. This is an inherently multi-enterprise, cross-functional
collaborative process that requires bringing together a vast amount of
data from disparate sources to make the right strategic, tactical and
In this webinar, we will discuss the strategic requirement to creating a successful value chain:
Real time analytics to balance supply and demand and optimize inventory levels and postponement strategies.
Visibility to address disruptions and detect patterns of supply chain behavior
B2B connectivity to optimize the inbound and outbound flow of materials
Evolution of the trading partner eco-system to reduce errors and speed fulfillment

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
A recent article in The Wall Street
Journal discusses the benefits of a foldable shipping container. This would be a big innovation in shipping.
Inbalances in supply and demand means that shipping companies must pay
to get their empty containers back to where customers want them.
importance of moving empty containers is simple:
a huge expense, a huge headache for the industry," says Neil Davidson
of London-based Drewry Shipping Consultants. The net cost of moving
empties is around $7 billion a year, say analysts.
foldable container would reduce the cost of shipping the empties.
However, these foldable containers cost around $4,000, or twice the cost
of the standard containers. And, the technology
has not yet proven robust enough for the realities of "heat, cold and
salt water of the high seas, and the rough handling of
Right now, the industry is not standing still.
IBM's ILOG Optimization solutions are being used to optimize the return
of the empty containers. The goal of the optimization is to get empty
containers to where they
are needed at the lowest cost. Of course, the containers do not have to
return from where they started and there are options for leasing or
buying new containers.
The problem can be difficult when you
start to consider such things as the different container types, the
capacities of ships, the costs of different modes of transportation, and
the long ocean shipping times.
Besides reducing costs, the
shipping companies using this technology
are seeing benefits in customer service by having the needed empty
containers in the right place at the right time and having the ability
to quickly re-plan when conditions change.
commitment to Analytics and Smarter Planet, provides additional benefits to this problem:
First, since there is variability in demand and supply, it is important
to correctly set the safety stock levels for empty containers at key
locations. Second, it is important to track and trace the containers so
you have better visibility but also to know when a container needs to
be replaced or repaired.
The Dec 2010 issue of Inbound Logistics reported that McKesson Corporation is using "IBM's Supply Chain Sustainability Management Solution to aggregate supply chain, sales, and geographic data to create "what-if" scenarios that enable distribution network modeling, supply planning, inventory positioning, vehicle routing, and sustainability management."
When optimization and analytics are applied to a firm's supply chain, you can often see significant returns on your investment. When you make this capability part of an overall framework, like McKesson did, you create a repeatable process to continually drive improvements in your supply chain.
IBM ILOG CPLEX Optimization Studio 12.5.1 is now available and brings another breakthrough in performance in solving mixed integer programs. Mixed integer programming models are solved on average 15% faster than the industry-leading prior release 12.5, on models requiring 1 second and above, and for the more challenging group of models requiring at least 100 seconds the average speedup is 40%. As a result of this breakthrough performance, two of the previously unsolved MIPLIB 2010 models have been solved: ns111636 and tw-myciel4.
Also included in the release are:
Additional scripting functions for use with the Optimization Programming Language. These extend the the conflict and relaxation iterators and support multiple MIP starts.
New methods in the conflict iterator class of the Java and .NET APIs of the Optimization Programming Language
