Abstract

In order to improve the comprehensive logistics support capability of domestic and foreign civil aircraft markets, and reduce the number of air materiel configuration and the cost of air materiel operation support, this paper proposes an air materiel configuration method based on air materiel sharing mode, considering the air materiel inventory and response time of each terminal. The Poisson process is used to describe the probabilities of different demand quantities of aviation materials during the study time; the aviation materials sharing group is constructed according to the transportation time relationship between the terminals; the marginal analysis method is used to expect largest number short-term aviation materials of all terminals in the sharing group to carry out air material configuration until the fleet availability needs are met, and the air material configuration technology under the sharing of air materials is realized. Studies have shown that under the specified fleet availability, the use of air material configuration technology under the condition of air material sharing can reduce the number of air materials in each terminal; the availability of the fleet can be improved under the same configuration number; The initial inventory can be maintained at a low level in the terminal group under the sharing condition. the research work has certain reference significance for improving the maintenance and support system of Chinese civil aircraft.

摘要

为了提升国产民机国内外市场的综合后勤保障能力，降低航材配置数量与航材运营保障成本，提出了基于航材共享模式，考虑各航站航材库存量与响应时间的航站组航材配置方法。采用泊松过程描述航材在研究时间内不同需求量的概率；依据航站间的运输时间关系构建航材共享组；采用边际分析法对共享组内所有航站中，航材期望短期量最大的航站进行航材配置，直至满足机队可用度需求，实现航材共享下的航材配置技术。研究表明：在规定机队可用度下，采用航材共享条件下航材配置技术可以减少各航站的航材数量；在相同配置数量条件下能提高机队可用度；共享条件下航站组内的初始库存量可维持在较低水平。研究工作对完善国产民机维修保障体系具有一定的参考意义。
