A method of replacement unit division of the exterior field that considers the development and maintenance

Abstract

The invention discloses a method for dividing replaceable units in the field considering development and maintenance. ; Step 3: Solve the optimization target model; Step 4: According to the solution results in Step 3, determine the repair level and repair method of each component in the equipment as the field replaceable unit. The present invention considers the influence of the development stage on the division of the field replaceable units, and comprehensively considers the cost of each part of the equipment from the development to the use and maintenance phase, so that the division is more suitable for the actual situation and more scientific and reasonable. At the same time, the main maintenance tasks at the basic level of the product are clarified by dividing, so that the equipment can be maintained and repaired in time, thereby ensuring the long-term performance of the equipment.

Description

technical field [0001] The invention belongs to the technical field of equipment maintenance and support, and in particular relates to a method for dividing replaceable units in the field considering development and maintenance. Background technique [0002] In the process of using and maintaining a large number of equipment / products, there are often some prominent problems such as high maintenance support costs, time-consuming and laborious maintenance, and low availability of equipment, which have a serious impact on product performance. The reason is that, on the one hand, these products have a high failure rate during use, and the guarantee conditions and capabilities at the grassroots level (civilian products can be called user-level, hereinafter referred to as the grassroots level) are limited; In the process, the traditional sequential design idea is still adopted, and sufficient maintenance engineering analysis and maintainability parallel design have not been carrie...

AI Technical Summary

Problems solved by technology

[0004] In the current LRU division process, most of the research is still oriented to the use and service phase, and few people have considered the influence of design factors, especially the characteristics of reliability, maintainability, testability, support and other maintenance support elements. Coupling relationship

In essence, the development costs brought about by different general quality characteristic design schemes are very different, and will also have a profound impact on the maintenance support planning and expenses in the use phase. For example, blindly pursuing the reduction of maintenance costs will lead to reliability design and test costs. The substantial increase of , which is very uneconomical for equipment with a not too long life cycle, the two should be considered comprehensively in the process of LRU division
