Abstract

In this paper, the Gray Theory is used to predict the residual life of shipboard cable. However, under the influence of multi-factors, the grayscale of the model will be enlarged, which will influence the accuracy of the prediction. Therefore, the optimized parameter of the GM (1, 1) model based on PSO, is introduced to improve the precision of the predication. The method is proved effectively by the experimental data and the Arrhenius Equation.
