矿井通风系统模糊可靠性研究

STUDY ON FUZZY RELIABILITYOF MINING VENTILATION SYSTEM(MVS)

定义模糊可靠度为一个服从正态分布的模糊数，并以模糊数作为通风系统的各风路可靠度，进而提出了矿井通风系统的模糊可靠度计算方法。同时在置信水平上，确定矿井通风系统的普通可靠度置信区间。若＝１，则模糊可靠度计算转化为可靠度计算。

n this paper,the fuzzy reliability is defined as a fuzzy number under the normal distributionand the fuzzy reliability of each branch of MVS is considered as a fuzzy number. Then a calcula-tion approach of MVS fuzzy reliability is proposed. And the confidence interval of usual reliabilityof MVS at confidence level is obtained.
