Abstract

Based on failure data of machining center, according to traditional random theory, analyze tool magazine by FMECA. Fuzzy the parameters of criticality, based on triangle-interval type-2 fuzzy membership function and algorithm of interval number on the type-2 membership function. Make judgment matrixes of interval number. Comprehensive evaluation of criticality rank of every failure mode is made by fuzzy comprehensive evaluation of interval number. Lastly, every failure mode´s criticality rank is got according to TOPSIS method and the algorithm of closeness degree. The above-mentioned method points out the weak parts of the tool magazine, it also can apply to fuzzy analysis on criticality of complete appliance, so as to provide basis for the reliability design and analysis of machining center.
