Covering a period of months to a year, this phase deals with aggregate resources. Here, planners look at "families" of products rather than individual units. The goal is to balance supply and demand, often utilizing strategies like hiring/firing labor, holding inventory, or subcontracting to smooth out production rates.
A standard PPC system operates across four sequential phases: Routing, Scheduling, Dispatching, and Follow-up. The first two belong to the planning phase, while the latter two comprise the control phase. 1. Routing (The "Where" and "How") the fundamentals of production planning and control pdf
MRP explodes the BOM, nets against inventory, and generates planned order releases. Covering a period of months to a year,
Scheduling assigns time constraints to the operations defined in the routing stage. It determines when the work starts and finishes for each component. Scheduling tools account for machine capacities, delivery deadlines, and labor availability to prevent resource over-allocation. Phase 3: Dispatching A standard PPC system operates across four sequential
If sales, inventory, and production teams do not share data transparently, the PPC system will generate flawed schedules. Conclusion
To execute a flawless production run, a manufacturing facility must guide each order through four sequential phases. 1. Routing
