An Improved Opportunistic Maintenance Method Introducing After-event Maintenance

Abstract

The invention discloses an improved opportunity maintenance method that introduces after-the-fact maintenance, which includes the following steps: dividing all components into two categories; calculating replacement probabilities for components of the first category and components of the second category, and The replacement probability includes failure replacement probability, opportunity replacement probability and preventive replacement probability, and the replacement probability of the second type of parts includes preventive replacement probability; calculate the expected maintenance cost rates of the first type of parts and the second type of parts respectively; use The expected cost rate of the two types of components establishes an optimization model to minimize the system maintenance cost rate. The present invention adds an exponentially distributed single-component model to the opportunistic maintenance strategy, and combines post-event maintenance with scheduled maintenance, thereby making the opportunity maintenance model more extensive. range of use.

Description

technical field [0001] The invention relates to an opportunity maintenance strategy, in particular to an improved opportunity maintenance method which introduces after-event maintenance. Background technique [0002] Since humans began to use mechanical equipment, it has been accompanied by equipment maintenance work. With the development of industry and the emergence of modern equipment, a relatively systematic and complete maintenance theory and management model have gradually formed. From the perspective of development process, it has mainly experienced the post-event maintenance stage. and preventive maintenance phase. With the intensification of competition in the market economy and the in-depth development of equipment maintenance management theories and methods, the maintenance strategy has changed from a single fixed maintenance strategy to a trend of diversification. It has become an important factor for enterprises to reduce production costs and improve economic be...

AI Technical Summary

Problems solved by technology

[0005] At present, some research has been carried out on the strategy of opportunity maintenance at home and abroad, but most of the consideration is the combination of different scheduled maintenance, and no consideration is given to the components whose single component failure model conforms to the exponential distribution
