摘要

针对任务期间普遍存在的故障件报废问题，提出了一种适用于多等级多层级航空装备的可用度近似评估方法。首先通过忽略维修和运输时间将存在报废率的可修件等效为消耗件，然后分别通过后方保障中心对飞行基地备件量的分配以及下层级部件对上层级部件备件量的折算，将多等级多层级备件模型转化为单等级单层级模型，最后利用伽马分布的可加性得到整个保障系统的装备可用度。在实际算例中，通过与仿真结果的对比得出：当维修和运输时间较小或飞行基地备件配置充足时，本文提出的近似评估方法具有较高的精度。

Abstract

For the problem of scrap of failure parts existing widely during the mission, an approximate evaluation method for availability of multi-echelon multi-indenture aviation equipment is proposed. Repairable spares with scrap are converted to non-repairable spares by omitting repair and transportation time. The spares are then assigned from the rear support center to the flight base and are converted from lower in to higher indenture successively, so that the multi-echelon multi-indenture spare model is converted into the single-echelon single-indenture ones. The availability of the whole support system is obtained based on the additive property of Gamma distribution. A comparison of the actual example with the simulation results shows that the approximate algorithm can be of high precision when the values of repair and transportation time are not too great or the spares of the flight base are sufficient.

Key words： during the mission; multi-echelon multi-indenture; scrap of failure parts; availability; configuration plan of spare parts
