Three Major Functions

   Planning

The flow of work through each of the work centers must be planned to meet delivery dates. So, the production must first, ensure that the required materials, tooling, personnel, and information are available to manufacture the components when needed. Second, schedule starts and completion dates for each shop order at each work center so the scheduled completion dates of the order can be met. This will involve the planner in developing a load profile.

  

Implementation

After the plans are made, the PAC must make the plans into an action by give the shop floor what must be done. The PAC usually give an instruction by issuing a shop order such as; gather the information needed by the shop floor to make the product. Then, release orders to the shop floor as authorized by the material requirements plan. This is called dispatching.

  Control

Once plans are made and shop orders released, the process must be monitored to learn what is actually happening. The PAC wiil do, rank the shop orders in desired priority sequence by work center and establish a dispatch list based on this information. Then, monitor and control wok-in-process, lead times, and work center queues.
