Embedded PP/DS: Heuristics, Optimizer and Pegging for Detailed Planning (Part 3)
Use embedded PP/DS to resolve detailed finite-capacity planning problems with heuristics, optimizer methods and pegging relationships rather than expecting classic MRP to produce an executable sequence.
Explanation
MRP primarily determines what and when to procure or produce. PP/DS adds detailed planning where resource capacity, sequence and material relationships must be considered more explicitly.
Heuristics apply deterministic planning logic to selected objects and are useful for repeatable planning strategies. Optimization can evaluate alternative schedules against cost and constraint settings, but only if master data and objective weights reflect the real business.
Pegging links requirements to receipt elements and helps planners understand which supply supports which demand. Changing one planned receipt can therefore affect multiple dependent requirements.
Detailed planning is only as good as resources, production data structures, calendars and setup information. Optimizer output should be reviewed, not accepted as inherently correct.
Real project scenario
A plant had sufficient total weekly capacity but daily overloads caused missed orders. Detailed scheduling exposed the bottleneck resource and sequence constraints that aggregate MRP planning had hidden.
Common mistakes
- Expecting MRP to produce finite detailed sequence.
- Running optimizer with poor master data.
- Ignoring pegging impact when rescheduling.
- Overconstraining every resource.
- Accepting optimized output without planner review.
Best practices
- Maintain resource master data.
- Use heuristics for clear planning logic.
- Tune optimization objectives carefully.
- Review pegging before major reschedule.
- Validate plans against shop-floor reality.
