Research on MRP/JIT integration and application in medical equipment production management concerned with spare part manufacturing

In the electromechanical production industry, especially in medical equipment manufactories, the mixed production of the original equipment and the maintenance spare part is very common. The implementation priority of the original equipment is higher than the maintenance spare part. In addition, the implementation and control of the production planning of maintenance spare part are restricted by the original equipment production. They could lead to the failure of the spare part´s production planning. In order to solve this type of problem, this paper proposes the MRP/JIT integration solution that can be applied in workshop production. In this solution, the production of the original equipment is controlled by MRP, while the spare part by JIT. The work flow of the material supply is also reengineered with material procurement Kanban and material requirement Kanban. The result showed that the feasibility of the production planning had been improved.
