针对可修复备份多级管理模型当备件关键性不同时无法再使用边际效应法的问题,以舰艇编队索马里护航备件携带为研究背景,提出了一种基于备件关键性的初始库存优化方法。首先,建立了备件关键性影响因素的评价指标体系,针对其具有模糊性的特点,采用模糊层次分析法(fuzzy analytic hierarchy process,FAHP)分析了备件重要度指标之间的相对权重的关系,给出了模糊判断矩阵及其一致性的求解方法;其次,给出了基于蒙特卡罗仿真方法的备件关键性求解模型和流程;再次,改进了边际效应法,建立了基于备件关键性的舰艇备件库存优化模型;最后研究表明,基于FAHP和蒙特卡罗方法求解备件关键性的模型可以降低人为主观性的影响,操作简单且易于实现;将修正了的边际效应法用于求解备件初始库存,有重点针对关键性较高备件的同时也能兼顾一般。

For the problem that the marginal effect method cannot be used by the multiechelon technology for recoverable item control model when the spare part criticality is different, the warship formation which carries the spares is taken as the research context in Somalia, and the optimized method of initial inventory is proposed which is based on the criticality of spare part. Firstly, the evaluation index system of the criticality which is affected by the factors of spare parts is proposed. It is a kind of complex problem with the characteristics of vagueness. The fuzzy analytic hierarchy process (FAHP) is used to analyze the relative weighting relationship between the index of critical spare parts and others, the solving method of fuzzy judgment matrix and its consistency is given out. Secondly, the mathematic model and solving flow of the criticality of spare part is proposed which is based on the Monte Carlo simulation method. Once more, the marginal effect method is improved. The warship spare part inventory optimization model is established which is based on the spare part criticality. Finally, the research result shows that the solving model of the criticality of spare part which is based on the FAHP and Monte Carlo method can reduce the influence of subjectivity. The operation process of model is simple and it can be easily achieved. The improved marginal effect method is used to solve the warship spares inventory. The critical spare part which is relatively high should be paid more attention meanwhile balance the general.
