Manufacturing control is concerned with managing and controlling the physical operations in the factory to implement the manufacturing plans. Mainly three types of controls are required in manufacturing:
- Shop floor control: It is concerned with the problem of monitoring the progress of processing, assembling, and inspection of the products in the factory.
- Inventory control: It is concerned with the demand fulfilment and also to reduce the inventory size to eliminate the wastage and minimize the investment. Thus, the optimum inventory size is maintained based on accurate demand forecasting.
- Quality control: The purpose of the quality control is to assure that the quality of the product and its components meet the standards specified by the product designer. To accomplish its mission, quality control depends on the inspection activities performed in the factory at various times throughout the manufacture of the product.
