摘要: 多级维修供应管理是提高装备保障效能的有效途径,备件的筹措和规划是影响装备可用度和形成战斗力的关键因素。在可修备件库存控制的多等级(METRIC)理论的基础上,放宽了模型中"无限维修总体"的假设条件,根据M/M/C排队论,对故障件的平均维修周转时间及备件供应渠道进行了修正,建立了备件的初始库存优化模型。在传统边际优化算法的基础上,通过引入分层优化的思想,对算法进行改进,使算法具有更高的运算效率,并在理论上对其进行了证明。算例结果表明:在保证计算结果完全一致的基础上,改进的分层边际优化算法能够大大提高运算效率。

Abstract: Multi-echelon maintenance and supply management is an effective approach to improve support effectiveness, and the preparation and programming of spare parts resources is a critical factor affecting equipment availability as well as combat power. Based on the multi-echelon technique for recoverable item control (METRIC) theory, the assumption for infinite repair channel is relaxed. According to the M/M/C queuing system theory, the computational model of average repair time and the pipeline for spare parts is modified, and an initial stock distribution model is established. Based on the traditional marginal optimization algorithm, a layered method is introduced to improve the traditional algorithm and achieve higher calculation efficiency, and it is analyzed and proved in theory. Example result shows that the calculation result of the improved layered marginal optimization algorithm is identical to that of the traditional marginal algorithm, while the improved algorithm can greatly improve calculation efficiency.

Key words: multi-echelon maintenance supply, finite repair channel, spare part, multi-echelon technique for recoverable item control, support effectiveness, layered marginal optimization
