摘要:

首先研究了串件拼修下两级保障体制的备件维修供应流程,分析了非串件拼修、串件拼修以及不完全串件拼修三种策略下的系统可用度;在此基础上,建立以系统可用度为约束条件,以保障费用最小化为目标函数的库存优化模型,并用边际效应分析法对模型求解。通过对比不同策略方案下的结果表明,在满足最低可用度下,采取串件拼修策略,可以降低库存量,减少总费用;在库存量一定下,采取串件拼修策略可以有效提高装备可用度。

Abstract:

First, the maintenance spare parts supply process of a two-echelon support system under cannibalization was studied, and the system availabilities under three strategies including non-cannibalization strategy, cannibalization strategy and partial cannibalization strategy were analyzed. Based on this, the inventory optimization model was established. The system availability was used as the constraint while the minimize support costs were taken as optimization objective, and the marginal analysis method was selected to solve the model. The results by comparing to different strategies indicate that taking cannibalization strategy can reduce inventory and total costs under minimum availability, and can effectively improve equipment availability under certain inventory.
