Research of Model and Algorithm of Multi-Item Spare Part Joint Replenishment Problem

Abstract

The research of joint replenishment problem in multi-item spare part inventory is an important orientation of inventory control, and it is difficult to solve. A model for continuity joint replenishment in stochastic demand is advanced. And the arithmetic is designed. Firstly, this arithmetic reserves reorder point of items according to the constraints of spare part supportability. Secondly, the cost and parameters of policy is computed. Finally, a solution is advanced for multi-item inventory cost. At last, the results indicate that the heuristic algorithm can effectively solve the problem.
