摘要:
针对考虑横向供应的多级库存配置问题,将维修比例这一实际因素引入库存配置模型中,提出了一种考虑横向供应及维修比例的民机备件多级库存配置方法。首先,阐述了考虑横向供应及维修比例下的多级库存配置模型的原理,并以机队可用度和备件满足率为约束条件,建立了相应的以库存系统总成本为优化目标的数学模型;其次,运用边际分析法求解考虑横向供应及维修比例条件下的备件多级库存配置;最后,以某航空公司波音737客机的部附件作为研究对象,在考虑横向供应及维修比例的条件下对其进行多级库存配置研究。算例结果得到了最优的备件库存配置数量,并且得到最低的库存系统成本为120.5万美元,机队可用度为0.990 9。相比不考虑横向供应及维修比例的传统配置模型以及只考虑维修比例的库存配置模型,所提出的模型使库存成本显著减少,可为民机备件的多级库存优化配置提供理论支撑和方法指导。

Abstract:
A research method for multi-echelon inventory allocation of civil aircraft spare parts with lateral transshipments and maintenance ratio is proposed in this paper, and the maintenance rate is considered into the inventory model, aiming at the problem of multi-echelon inventory allocation with lateral transshipments for civil aircraft spare parts. Firstly, the principle of the multi-echelon inventory model with lateral transshipments and maintenance ratio is proposed. Then, by considering the fleet availability and the satisfaction ratio as the constraints, a mathematical model is built with the inventory system total cost as the optimization objective. Secondly, the procedure of solving multi-echelon inventory allocation model considering the influence of lateral transshipments and maintenance ratio is discussed based on the marginal analysis method. Finally, some components of Boeing 737 are selected as the research objects, the multi-echelon inventory allocation is investigated by considering lateral transshipments and maintenance ratio. The analysis results in this paper show the best number of multi echelon inventory allocation, the minimum inventory system total cost and the fleet availability are 1.205 million dollars and 0.9909 respectively. Comparing the traditional inventory model without considering lateral transshipments and maintenance ratio, and the model which only considers the maintenance ratio, the results indicate that the model offered in this paper could reduce the total cost of inventory system significantly, and provides theoretical support and method guidance for the accurate allocation of multi echelon inventory optimization for civil aircraft spare parts.
