The aim of this study was to improve the low accuracy of equipment spare parts requirement predicting, which affects the quality and efficiency of maintenance support, based on the summary and analysis of the existing spare parts requirement predicting research
According to the characteristics of the time series data with equipment spare parts consumption, this article proposes to use long short-term memory (LSTM) recurrent neural network to predict the requirement of equipment spare parts, in which the technical advantages of LSTM recurrent network will be fully performed
In order to solve the problem that the LSTM recurrent neural network prediction model involves many parameters, which will make the performance of prediction unstable if set artificially, with the goal of minimizing the prediction error, an algorithm of equipment spare part requirement prediction with LSTM recurrent neural network whose parameters are optimized by particle swarm optimization is further proposed
