| The fuzzy reliability of a kind of systems in production management with fuzzy parameters is analyzed in this thesis based on fuzzy structured element. The complicacy and infeasibility of fuzzy number's operation based on Extension Principle in tradition analysis of fuzzy reliability is overcome availably.In this thesis, we get the models of fuzzy system reliability with fuzzy parameters. Further more, we get these membership functions based on two new methods of confirming membership function. It offers a new way to research the kind of system reliability for researchers.In chapter 6, the mine production systems fuzzy reliability is empirical researched based on these models we given. We can get a confidence interval when the confidence and the time of system working are given. It is more significant than an exact value come from tradition method of fuzzy reliability analysis. |
