摘要
合理的维修备件配置是提高鱼雷保障能力的重要因素。为了权衡维修备件的满足率需求与利用率之间的矛盾,文中分别针对寿命周期服从指数分布的不可修备件和可修备件,以单备件满足率与系统满足率作为约束条件,系统利用率作为目标函数建立配置模型,应用边际效应算法对模型进行求解,最后通过算例,验证了配置方案的合理性和有效性。该方案可为鱼雷基层级维修、基地级维修初始备件数量确定提供参考。
Reasonable allocation of spare parts is an important factor to improve the support capability of a torpedo. To balance the contradiction between demand rate and utilization rate of spare parts, a allocation model based on the initial spare parts allocation is built for the repairable and unrepairable spare parts with life cycles obeying exponential distri- butions. The single spare part satisfaction rate and the system satisfaction rate are taken as the constraint condition and the system utilization rate as the objective function to establish a configuration model. The marginal effect algorithm is used to solve the model. Examples verify the rationality and effectiveness of the proposed scheme. This research may provide the reference for quantity determination of torpedo＇s initial spare parts in organizational-level or depot-level maintenance.
