Abstract

Abstract: Aiming at the configuration problem of block spare parts in k/N systems, an optimal configuration method of block spare parts considering cannibalization and on-condition maintenance was proposed. A spare parts fill rate model for k/N systems was established on the basis of two parameters named cannibalization rate and SRU replacement rate, and the constraint conditions of both the parameters were given respectively. An optimal configuration model was built, which chose the minimum spare costs as the object and the spare fill rate as the subject, and a model solution algorithm based on the margin analysis theory was given. Simulations and analysis were conducted by taking the spare parts configuration problem of one large-scale phased array antenna as an instance, and the optimal results were achieved through the simulation methods of quantitative and comparative analysis. The results show that the presented model is of high validity and feasibility, and can provide theoretical support for the deeply research on the block spare parts configuration problems for k/N systems.

Key words: k/Nsystems, block spare parts, spare parts configuration, cannibalization, spare parts fill rate
