Abstract

Abstract:

For the difficulty in predicting time between weapon failures, a grey Markov model is established based on grey model (1,1). And a combined model for the prediction of the time between failures is established by analyzing a typical failure rate curve of electronic equipment and forming a reasonable modeling background according to the characteristics of electronic equipment faults. The predicted value is compared with the real value through an instance. The result shows that the combined model can be used effectively to predict the time between failures, reduce the prediction error and improve the prediction accuracy in the case of few data, poor information and uncertainty.

Key words: probability, gray Markov model, prediction, time between failures
