基于可靠性約束的衰退設(shè)備動(dòng)態(tài)預(yù)防性維護(hù)模型
[Abstract]:In view of the fact that the preventive maintenance strategy of declining equipment usually only considers the influence of a single factor on the maintenance policy, but neglects the influence of multiple factors on the maintenance cost, this paper analyzes the influence of maintenance times and reliability on the maintenance strategy. Taking the minimum maintenance cost as the objective function, the dynamic preventive maintenance model of recession equipment is constructed. In the process of establishing the model, the relationship between equipment reliability and failure rate is put forward for the first time. Finally, the rationality and validity of the model are verified by an example, which provides a new method for dynamic preventive maintenance strategy under reliability constraints.
