Multiattribute decision-making analysis of equipment support system assessment

A multiattribute decision-making model based on ideal point was put forward to solve the problem that quantitative index and qualitative index band together in estimation of equipment support. In this paper, basic elements of equipment support system were analyzed and the quantitative methods put forward, and the mixed multiattribute decision-making principle introduced. The rationality of the model was validated by analyzing an example. The result indicates that this model can reflect the approach degree between fuzzy attribute values of factual projects and ideal project in the decision-making space and advance the veracity of system assessment.
