In this paper,the grey system forecasting theory is used to forecast the products reliability life test data,and the modeling approach of NGM(1,1) grey prediction model for products reliability life test data is proposed.By examining the overall distribution function equality of test data sequence and forecasted data sequence,it is confirmed that the proposed NGM(1,1) grey prediction model can be effectively used for the prediction of product reliability life test data.The example results show that the grey...
