Master Production Scheduling It forms the link between production planning and what manufacturing will

Master Production Scheduling It forms the link between production planning and what manufacturing will actually build. It forms the basis for calculating the capacity and resources needed The MPS drives the material requirements plan. AS a schedule of items to be built, the MPS and bills of material determine what components are needed from manufacturing and purchasing. It keeps priorities valid. The MPS is a priority plan for manufacturing.

Master Production Scheduling • Master Schedule Decisions Make-To-Stock Products: The MPS is usually a schedule of finished-goods items. Assemble-To-Order Products: It’s much easier if production is planned in subsystem level. Make-To-Order Products: The MPS is usually a schedule of the actual customer orders.

Master Production Scheduling • Final Assembly Schedule (FAS) This last step, assembly to customer

Master Production Scheduling • Final Assembly Schedule (FAS) This last step, assembly to customer order, is generally planned using a final assembly schedule. This is a schedule of what will be assembled. It is used when there are many options and it is difficult to forecast which combination the customers will want. The final assembly takes place only when a customer order is received.

Master Production Scheduling • Rough Cut Capacity Planning (RCPP) Rough-cut capacity planning checks whether critical resources are available to support the preliminary master production schedules. Critical resources include bottleneck operations, labor, and critical materials (perhaps material that is scarce or has a long lead time).

Master Production Scheduling • The Objectives In Developing an MPS To maintain the desired level of customer service by maintaining finished goods inventory levels or by scheduling to meet customer delivery requirements. To make the best use of material, labor, and equipment. To maintain inventory investment at the required levels.
