Abstract

BDD technique is applied to analyze the parts importance of the CNC machine tools. Through calculating, parts importance is listed according to the values. The structure importance and probability importance of the power system are calculated in the paper. From the results we can see that the values of the two methods are perfectly close. But BDD methods are more effective than the FTA methods and can be calculated with the computer
