Reliability Analysis of Condition Monitoring Systems under FuzzyEnvironment
As an important means to improve the reliability of complex manufacturing systems and toensure that they can function better,condition monitoring systems (CMS) are usually designed andused in manufacture industries.And reliability is one of the most important characteristics of CMS.Fuzzy set theory based on reliability modeling and analysis methods for CMS are proposed in thispaper.The methods include a fuzzy graph modeling technique for analyzing the system reliability ofCMS,and fuzzy reliability computing methods to quantify uncertainties in function decomposition ofCMS and compute system reliability of CMS by invoking Fuzzy-set theory and approaches.On theother hand,the fuzzy reliability of CMS based on fuzzy failure subset and confidence level is defined,and system reliability indexes of CMS are set up to compute the system reliability of CMS.A case ofapplication is used to illustrate the procedure.
