Research on fuzzy optimization model of unmaintainable spare parts for torpedo

The determination of the spare part amount of torpedo is an important work of maintenance and relative to cost and spare part supportability closely. So the cost and the spare part supportability should be considered when the spare part amount is optimized. The fuzzy optimization model of the demand amount of unmaintainable spare part based on the analysis of the fuzzy characteristic of the spare part supportability was set up. The optimization results of spare part amount of the torpedo were obtained by the model and provided specific data. The results show that the method is a certain value to engineering application.
