Release Notes
Abstract
This document provides the release notes for Maximo Optimizer 9.2.0
Content
- Known issues fixed in IBM Maximo Optimizer 9.2.0 release
- DT423640 - MAS Admin displaying incorrect values for Optimizer configuration when using Limited plan.
- DT471493 - Optimizer remains in invalid state after Mongo communication loss causing Optimization process accumulation.
- DT464597 - Duplicate API deployment due to missing workspace cleanup
- DT466939 - Internal Service Route OIDC refactoring
- Security Updates
Includes important security patches across base images and core components. - FISMA High Compliance
Ensures compliance with FISMA High security requirements, meeting stringent federal standards for risk management, data protection, and information system security controls. - Elastic Scaling for Execution Service Pods in MAS
Introduces elastic scaling for Execution Service Pods in MAS, automatically adjusting capacity based on CPU utilization through the Horizontal Pod Autoscaler to improve performance and resource efficiency. - Improve execution service job sequencing and balancing
Improves execution service job sequencing and load balancing by enforcing FIFO queue processing and distributing jobs evenly across pods using round-robin scheduling, ensuring fair execution order, optimal resource utilization, and resilience to pod failures. - Custom Log4j2 for IBM MAS Optimizer
IBM MAS Optimizer now supports external Log4j2 configuration via Kubernetes ConfigMaps to meet FISMA and FIPS audit requirements. This feature allows customers to override the default logging configuration for API and Execution Service components without rebuilding application artifacts (technote). - Migration to Graphite UI Framework
Migrates the user interface from standalone ReactJS to the MAS-standard Graphite framework, enabling a more consistent user experience, improved maintainability, and alignment with Maximo Application Suite design and capabilities. - Migration to Java™ 25
Maximo Manage and Maximo Optimizer now support Java 25. For more information, see IBM Maximo Manage: Transition to Java 25. - Configurable Refresh Interval for Optimization Jobs Progress
The execution service now supports a configurable refresh interval that controls how frequently job INFO is updated during optimization execution. - Enforce Material and Tool Availability
Enhances scheduling accuracy by enforcing material and tool availability constraints across GA, GS, and GSLP, considering work order requirements, storeroom capacity, technician-assigned inventory, and lead times, with a activation toggles to optimize resource-aware planning. - Enable Rotating Shifts for Labor
Introduces support for rotating and ad‑hoc shifts for labor and crews, allowing dynamic override of default schedules with customizable working hours to improve planning flexibility for GA and GS scenarios. - Run What-If Analysis with Natural Language and GenAI
Introduces a new directives section enabling what-if analysis through parameters, predefined rules, or natural language inputs powered by GenAI (via watsonx), allowing users to dynamically modify optimization scenarios across GA, GS, GSLP, and Dashboard applications. - Enhanced Large Neighborhood Search for Dispatch Optimization
Enhances the Large Neighborhood Search (LNS) algorithm to improve large-scale dispatching efficiency while supporting additional business constraints such as precedence, parallel assignments, calendar preferences, travel time limits, and technician-level tool availability, resulting in more realistic and optimized scheduling outcomes. - Explain Unassigned Work Orders in Optimizer
Provides detailed explanations for why work orders are not scheduled, enabling users to identify constraint violations and resolve scheduling issues more effectively. - Improve Capacity Planning Optimization
Enhances capacity planning capabilities to help meet project deadlines by allowing planners to model and allocate additional craft and shift capacity within defined constraints. - View and download conflict diagrams
Introduces graphical conflict diagrams available as downloadable HTML reports, helping users identify and understand constraint violations and root causes. - Consider assignment status during optimization
Enhances optimization by preserving accepted or in-progress assignments and respecting rejected assignments based on defined rules. - Additional Fields for Relationship Constraints
Adds configurable fields such as maximum lead/lag limits, optional dependencies, and shift-based lead/lag interpretation. - Enhanced Business Rules for Assignment and Dispatching
Expands capabilities with rules for travel limits, workload constraints, location calendars, and task precedence, enabling more precise scheduling decisions. - Enhanced Business Rules for Scheduling and Large Project Planning
Enhances scheduling and large project planning with new business rules, including support for non-interruptible parent work orders, adjustable service duration, periodic PM constraints, and improved priority handling for work orders without defined priority, resulting in more accurate and realistic optimization outcomes.
