鱼雷装备备件隶属关系的两级库存系统配置优化研究

摘要

Echelon system optimizing is an important approach to improve operational readiness and reduce life cycle cost for equipments. Through analyzing the two-echelon system for LRU and SRU spare parts of complex equipment,under a given spares configuration scheme,a calculating model of spares out of stock is proposed. Then spares configuration models of a two-echelon system is built based on spare parts contained relation. This model aims to save the spares configuration cost and avoid waste of resources through optimizing the spares configuration structure and generating a better spares configuration scheme.%备件库存系统配置优化是提高武器装备的战备完好性和降低寿命周期费用的重要途径，但在装备组成结构中，由于部件之间存在一定的隶属关系，并不是所有的项目都能够进行串件。针对现有两级库存系统备件配置优化研究的不完善之处，根据装备结构层次特点，通过分析鱼雷装备LRU和SRU备件两级库存系统，提出了备件初始配置方案下的备件库存缺货数模型，并在此基础上建立了基于备件隶属关系的两级库存系统配置优化模型。该模型以鱼雷装备使用度和库存费用为优化目标，通过优化备件库存配置结构，生成较好的备件库存配置方案，从而节约备件配置费用，避免造成资源浪费。
