Criticality analysis of machining centers based on fuzzy mathematic

Utilizes fuzzy mathematics theory to scientifically analyze the criticality of machining centers. Based on occurrence probability and serious degree of fault ,two important factors—Test and Maintainability were considered,and carry out fuzzy synthetic assessment to the factors related to the failure mode criticality,thus the influence factors of traditional criticality analysis were expanded,and the questions of fault analysis were changed more and more scientifically and reasonable. By arranging the synthesize appraisal result ,it will provide direction and foundation for further to improve and enhances reliability. It is also a new method to process the qualitative problem of analyzing criticality with quantitative method.
