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

Embodiment Construction

[0034] The implementation of the present invention is described below through specific examples and in conjunction with the accompanying drawings, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific examples, and various modifications and changes can be made to the details in this specification based on different viewpoints and applications without departing from the spirit of the present invention.

[0035] Before introducing the present invention, briefly explain the classic principle of opportunity maintenance. The understanding of opportunity maintenance is as follows: figure 1 As shown, when the component runs before the opportunity maintenance threshold W, if it fails, it will be replaced. When a component runs between W and the preventive threshold T, if a component fails, a faul...

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...
