Abstract

The effective degree is studied in reliability of mine coal mining machine by using the fuzzy structured element theory. Firstly, the fuzzy reliability, fuzzy maintainability and fuzzy effective degree are defined. The analytic expression of fuzzy effective degree are put forward by using the structured element theory and fuzzy extension principle. An example is given to calculate fuzzy effective degree of winning machine. The example indicates that fuzzy effective degree is the non-symmetric fuzzy number on [0.56, 0.99] and the method of calculating for the classic effective degree over-estimated the reliability of the mining machine.
