Assessment of Influence Factors of Infrastructure Sustainability Based on Group Decision-making Model

Abstract:

According to the issue that the influence factors of infrastructure sustainability (IS) are abundant and complex, which generates that traditional evaluation methods are difficult to objectively analyze the weight of influence factors of IS. According to this issue, the multi-attributes group decision-making model is established based on the relation degree theory, and introduces comprehensive weight-modification matrices and optimizes the weight of influence factors of IS from three aspects: information deviation, consistency and information entropy. And the model is verified by the empirical analysis in terms of practical project data. The application of this model would improve the objectivity of the evaluation of IS.
