Abstract:

Maintenance material is the basis for effective implementation of maintenance support. It is the key to make decision of carrying material variety. In order to solve the problem which is difficult to determine the carrying material varieties due to various types of material in the stage task, the complex influencing factors and unclear association relationchip, a method for determining carrying material varieties of stage task combined with the improved sparse kernel principal component analysis (SKPCA) and long short-term memory (LSTM) neural network model is proposed. On the basis of analyzing the influencing factors and characteristic indicators of stage task carrying material, an improved SKPCA dimension reduction method based on elastic penalty is proposed which can reduce the material features dimensionality and obtain low-dimensional sparse feature vectors to enhance the data interpretability. The chaotic sequence is used to improve the flower pollination algorithm (FPA) which optimizing the LSTM hyperparameters and the chaotic FPA-LSTM prediction model is constructed. Through the example analysis by the exercise, the scientificity and feasibility of the proposed method are verified.

Key words: carrying material, stage task, sparse kernel principal component analysis (SKPCA), influencing factor analysis, flower pollination algorithm (FPA), long short-term memory (LSTM) neural network
