摘　　要：实施串件拼修对策是提高装备保障效能的有效途径,能够在现有保障条件下使装备可用度达到上限。针对该问题,在备件多级维修供应模式下,根据串件拼修的特点,并结合可修复备件库存分配建模理论(METRIC),建立了非串件系统、串件系统以及不完全串件系统可用度评估模型。研究了串件对策下装备保障效能的分析流程和方法。通过实验设计,确定初始备件库存方案,在给定的方案下,对不同串件对策下装备的可用度进行评估。采用VMETRIC平台对模型进行验证,结果表明,本文模型结果与VMETRIC仿真结果具有相当高的吻合度,证明了模型的正确性。Cannibalization policy is an effective approach to improve support effectiveness. Under the current support condition, it can make equipment availability reach the upper limit. This paper establishs respectively availability models of a noncannibalization system, a cannibalization system and a partial cannibalization system under the mode of multiechelon maintenance supply in accordance with the characteristics of cannibalization combined with multiechelon technique for recoverable item control（METRiC） theory. The analysis flow and method of support effectiveness are studied. In a given ex ample, The initial spare parts inventory project is obtained under which the equipment availability is analyzed with different cannibalization policies. VMETRIC simulation is used to test the results, and the verification shows that there is high consistency between the two results, which proves the validity of the model.
