Description
Summary:In order to solve the problem of weighting factor in the maintenance comprehensive weighted allocation model based on failure rate and design characteristics. Firstly, the fuzzy comprehensive evaluation method is introduced. Secondly, the fuzzy judgment matrix is established by using the three-scale method and the weight is obtained. Then the binary fuzzy contrast is used to establish the relationship matrix of the influencing factors and the evaluation matrix is obtained. The weighting factor is calculated by the fuzzy transformation. When the failure rates vary widely, the allocation results will weak the design characteristics by relying on the failure rate. So the weighting factor should be modified to improve the rationality of the distribution result. Finally, take a machining center as an example to verify the maintenance distribution application.
