Fuzzy Optimization Theory In The Water Transfer Schemes In The North-south Water Diversion Project

The North-to-South water diversion project is a large water a I locat i on project from one river basin to another r i ver basin in the northeast of China. One of the main problems of the project is how to determine the scale and amount of water allocated. Since the scenarios of water allocation involve many factors,some of them are quantitative,some are qual itative,it is hard to solve using classical methods. In this paper,fussy optimal selection theory was adopted and model ing was set up to investigate the problem based on former experiences of research. It was found that the scenario of 200mVs is the optimal scenario of water allocation after compared six scenarios and nine quantitative or qualitative objectives. Theresult isconsistentwithwhat obta i ned us i ng classical economic evaluation method. It is the first time to determine the amount of water al located using fuzzy optimal selection theory in the North-to-south water diversion project. It appears both feasible and practicable.
