Multicriteria Decision Making in Water Resources Planning and Management using Fuzzy Sets
, M.Sc. Thesis Sharif University of Technology ; Shamsai, Abolfazl (Supervisor)
Abstract
Water resources planning and management projects are done in order to accomplish several goals. Moreover, social, environmental, political etc impacts of such projects increase the complexity of the problem of choosing the best alternative among others. The project of diversion of water form Zab Watershed into Lake Urmia Watershed is one of these projects which regarding water demands and problems in Lake Urmia Watershed and also Zab Watershed water resources that exceed its water demands has been considered. Therefore, after conducting research studies, five locations have been determined as potential places to build a dam on the Zab River and transferring its water to Lake Urmia Watershed....

Abstract
Taking account of uncertainty in multicriteria decision making problems is crucial due to the fact that depending on how it is done, ranking of alternatives can be completely different. This paper utilizes linguistic values to evaluate the performance of qualitative criteria and proposes using appropriate shapes of fuzzy numbers to evaluate the performance of quantitative criteria for each problem with respect to its particular conditions. In addition, a process to determine the weights of criteria using fuzzy numbers, which considers their competition to gain greater weights and their influence on each other is described. A new fuzzy methodology is proposed to solve such a problem that...
