Abstract:

Cannibalization policy can improve the availability of equipment furthest,but not all units can use the method. Focusing on the incomplete cannibalization system, under the mode of multi-echelon maintenance supply, according to the characteristics of cannibalization and combining with multi-echelon theory for recoverable item control (METRIC) theory, the availability model of the incomplete cannibalization system is established and the analysis flow of the optimal spare parts’ project is researched. In a given example, the equipment availability is analyzed with different cannibalization policies, and the result proves the method is valid for the incomplete cannibalization system. The vary METRIC (VMETRIC) software is used to test the result, the verification shows that there are highly consistency between the two results, which proves the model’s correctness.
