Application of AHP in Benefit Evaluation on the Equipment in Whole-life Cycle

In this paper, we employ the AHP methodology combined with the fuzzy systematic benefit assessment method to establish the hierarchy architecture for making benefit evaluation on the equipment in whole-life cycle. According to module division and hierarchy architectures construction, the methodology establishes a benefit evaluation index system, in which weight is endowed to different alternatives as well as evaluators involved. Then a parameter model is constructed on the hierarchy architecture. Through synthesis and calculation, the ultimate economic benefit value of the equipment in whole-life cycle is obtained.
