【 摘 要 】

In view of the fuzzy boundary problem in the criterion of accident grade classification, the number of deaths, the number of injuries and the direct economic losses of accidents are taken as evaluation elements respectively, and the judgment matrix of accident grade is constructed. The influence weight of indicators is calculated by AHP and the consistency of judgment matrix is checked. Taking some typical production accidents as an example, the membership function is constructed according to the existing accident indexes. In this paper, an accident grade classification method based on fuzzy evaluation system is put forward, and the accident evaluation matrix is obtained, and the accident grade is determined according to the principle of maximum membership degree. To a certain extent, it can provide scientific reference and reference basis for the qualitative analysis of accident grade.
