Study and Application of the Life-Cycle Cost Control Model of Water Conservancy and Hydropower Project Based on Entropy and FAHP

How to implement the life-cycle management of water conservancy and hydro power project cost effectively, and how to distinguish the influence degree of different factors on project cost stage management. This is a key problem in project cost control. In this paper, based on the influence of each factor on the overall evaluation goal influence, FAHP is applied to set up Fuzzy Comprehensive Evaluation Model. Aiming at the variability characteristics of factors in each stage, the information entropy is used to determine the objective weight in the model, in combination with AHP the subjective weights to determine the weight.
