Spare Parts Configuration of Phased Array Radar Based on Cannibalization

Abstract

Aiming at the characteristic of batch replacement and batch sending to repair for the large phased array radar’s spare parts, a configuration model of LRU and SRU based on cannibalization is established. Firstly, this paper selected three kinds of LRU and the SRU which is subordinate to the LRU as the research object, broke the traditional constraint of unlimited maintenance capacity at the depot-level, then established a spares of LRU and SRU configuration model that minimizes the acquisition cost of system under the restriction of the expected fill rate of LRU and SRU, lastly marginal efficiency analysis algorithm was applied to achieve the specific parameters. The living examples show that the model can optimize the parameters including number of spare parts, feasibility of cannibalization and replacement rate of SRU, which will improve the supporting effectiveness of large phased array radar.
