Control Mechanisms

In traditional manufacturing systems, there are two types of production control mechanisms, such as a push system and a pull system. In the push system, production occurs according to a predetermined plan, and materials are normally scheduled to arrive at the line according to a materials requirements plan (MRP). The main disadvantage of this system is excess inventory. On the other hand, the pull system aims to increase the agility of the system by reducing inventory levels. This is achieved by allowing production only if there is a demand for the product. Some of the bene€ts of the pull system include reduction in bottleneck, cycle time, and inventory-carrying costs. Hence, the pull system has a potential to be implemented in a remanufacturing system, especially in a disassembly line where production is labor intensive and products have limited shelf lives, high carrying costs, or need large storage space.
