Abstract:

A wartime repairable spares support planning model is presented based on the three-echelon support structure, in which multi-stage characteristic is considered. The stage expected number of backorders is taken as the performance parameter; both its definition and expressions are given. The iterative method is adopted to get the optimized strategy, the computing process is given considering the destroyed spare can all be repaired or not. Based on the dynamic Palm theory, how to compute the expected number of backorders is illustrated when spare numbers in pipeline is Poisson distribution. An example is given in the end.
