Research on evaluation model of spare parts support effectiveness for large phased array radar

Spare parts support plays an important role in the application of radar equipment, especially for large phased array radar. Scientific spare parts support evaluation is an important means to improve the integrity of radar equipment and reduce life cycle maintenance funds. Spare parts support rate, spare parts out of stock and spare parts utilization are three important indicators for the evaluation of spare parts support capacity. In view of the lack of evaluation indicators, an evaluation model based on these three indicators is proposed, and finally an example application is proposed. The effectiveness and feasibility of the model in evaluating the effectiveness of equipment spare parts support are verified by an example. Finally, the results are obtained, which improves the integrity of equipment and saves equipment funds.
