The Fuzzy Time-Cost-Quality-Environment Trade-off Analysis of Multi-mode Construction Systems for Large-scale Hydroelectric Projects

摘要

This paper studies the time-cost-quality-environment trade-off problem of construction project and establishes a multi-objective decision making model under a fuzzy environment. The objective functions are to minimize the total project time, total executed cost, quality defect of all activities, and the environment impact. Furthermore, a fuzzy based adaptive-hybrid genetic algorithm is developed for finding feasible solutions. Finally, Jinping-Ⅱ hydroelectric project was used as a practical example to demonstrate the practicality and efficiency of the method.
