A master production schedule (MPS) is a plan for individual commodities to be produced in each time period such as production, staffing, inventory, etc.[1] It is usually linked to manufacturing where the plan indicates when and how much of each product will be demanded.[2] This plan quantifies significant processes, parts, and other resources in order to optimize production, to identify bottlenecks, and to anticipate needs and completed goods. Since a MPS drives much factory activity, its accuracy and viability dramatically affect profitability. Typical MPSs are created by software with user tweaking.
