Abstract:

Reasonably programming the configuration project for repairable spare parts is critical for improving maintenance supply effectiveness. Based on the multi-echelon theory for recoverable item control (METRIC), considering relative important repair parameters, the universal model of spare parts configuration optimization under the discretional structure equipment and discretional support mode is built. Taking the equipment availability, spare parts fill rate and support delay time as the targets, while the cost is considered as the constraint, the marginal algorithm is used to the model calculation. According to a given example, the support factors of impacting the spare parts’ configuration project are analyzed. The calculation result is verified through VMETRIC simulation software, which proves the model’s correctness.
