备件横向转运补给是提高装备保障效率的有效途径,针对现有研究不适应部队多级维修供应模式的问题,根据VMETRIC和生灭过程理论,建立了三级保障模式下多类可修备件的库存转运模型,运用启发式算法对模型进行求解,通过仿真验证了算法的正确性。研究了多种保障效能评估指标,以装备可用度为约束、备件购置费用最低为目标,采用边际优化算法得到最优库存方案,并与非转运条件下的方案进行比较。在实际案例中,本文构建的转运模型在提高各项保障效能指标的同时使备件购置费用降低了22.35%。
Transverse transport of spare parts is an effective way to improve the efficiency of equipment support. In view of the existing research does not meet the military multi-level maintenance supply model, according to VMETRIC and birth and death process theory, the establishment of a multi-class three-level maintenance mode spare parts inventory Transport model, using heuristic algorithm to solve the model, the simulation results verify the correctness of the algorithm. A variety of evaluation indexes of security effectiveness are studied. With the aim of minimizing the availability of spare parts and the lowest purchase cost of spare parts, the marginal optimization algorithm is adopted to obtain the optimal inventory plan and compared with the non-transit plan. In the actual case, the transport model constructed in this paper can reduce the purchase cost of spare parts by 22.35% while improving the various performance indexes.
