Production control involves organizing and handling materials, parts, assemblies, and sub assemblies efficiently from their initial to finished states. It includes routing, loading, scheduling, estimating, dispatching, and expediting. Routing determines the manufacturing operations sequence. Loading assigns work to machines or departments in advance. Scheduling determines when each operation will take place and production plans for the next weeks or months. Estimating determines production job costs. Dispatching assigns work to machines or locations based on scheduling priorities. Expediting regulates and checks material and part progress through production.
