Abstract

The invention relates to a method for evaluating the maintenance degree of a product. The method comprises the steps that S1) influential factors of the maintenance degree are determined; S2) the weight of each influential factor is determined; and S3) the maintenance degree of the product is obtained by combining the weights of the influential factors with the evaluation values of the influential factors. Compared with the prior art, the maintenance degree is evaluated based on the weight of each influential factor, so that the evaluation result is more objective and real.

Description

technical field [0001] The invention relates to a maintainability evaluation technology, in particular to a product maintainability evaluation method oriented to the whole life cycle. Background technique [0002] At present, mechanical equipment has many performance indicators, but its maintainability is often not paid enough attention to. At present, in the field of domestic machinery, the meaning of maintainability is often included in maintainability, causing confusion between the two, and they are mistaken for the same concept, which is actually very wrong. Routine maintenance of equipment usually includes cleaning, lubrication, fastening, and plugging, while maintenance is to inspect and repair equipment after failure and restore it to normal working condition. The implementation stages of the two are different, the operation methods are different, and the costs are also different. On the other hand, today's product structure is becoming more and more complex, with m...
