Abstract: Due to the fact that in ship maintenance process, the method of determining the number of spare parts is not scientific and the actual operation is complicated, this paper analyzes four major factors affecting the number of ship spare parts, including number of main planned operations, total times of disassembling in maintenance, accumulated working time and mean time between failures. It also establishes a spare parts demand forecast model based on the affecting factors and radial-basis function (RBF) neural network. Finally, the paper provides forecast examples and makes a comparison between the examples and back propagation (BP) neural network forecast result. The comparison results show that the forecast based on RBF neural network is simple and the forecast result fits the actual situation and fitting effect is better than that based on BP.

 

Key words:spare parts forecast;  neural network; equipment support
