Integrating MRP with Kanban/Pull Systems

Push manufacturing systems like MRP and pull systems like Kanban, are sometimes thought of as representing antithetical approaches to controlling production. However, these approaches involve principles that are not incompatible. A hybrid system is described that combines MRP at the plant-wide level with a Kanban approach at the local cell level. The calculations required in the MRP system are simplified, but the ability to utilize advance information about demand is retained. Simultaneously, the reactive abilities and the appealing incentive structure of the Kanban system are incorporated in the hybrid system. This approach is appropriate for a repetitive batch manufacturing environment, with part fabrication, subassembly and assembly stages
