Fuzzy Theory Based Multi-objectives Evaluation Models and their Applications on Water Resources Allocation

Water resources allocation relates to many decision factors, such as society, economy, environment and resource utilization, which is a complicated and uncertain decision-making process. Usually, the problem of conflict and competition among the different targets and water users should be solved. Taking Dalian´s water resources allocation as an example, this paper develops a multi-objectives evaluation index system. On the basis of it, water resource allocation schemes are evaluated and inter- compared with multi-objectives fuzzy optimization model, grey correlation analysis method and fuzzy variable assessment method to avoid the subjectivity and blindness of the decision-making. And a relative satisfied scheme is obtained, which will improve the decision-making for water resources allocation in Dalian.
