Complex equipment component maintenance level optimization system and establishing method of thereof

The invention relates to an equipment maintenance scheme and specifically relates to a complex equipment component maintenance level optimization system and an establishing method thereof which are especially applicable to complex equipment component maintenance level optimization. The method comprises the following steps of: establishing a maintenance level knowledge base, acquiring a model for unearthing the relationship between a component maintenance level and the contribution to whole equipment performance of a component on the basis of a supported vector machine, and determining a component maintenance target; obtaining a lowest component maintenance level; and optimizing the maintenance level of each component. Compared with the prior art, the complex equipment component maintenance level optimization system and the establishing method thereof can improve the complex equipment component maintenance efficiency and have the advantages of accuracy and reliability and the like.
