Selection of Water Utilization Strategy with Fuzzy Ahp and Fuzzy Anp Methodologies under Global Warming Risk

ABSTRACT Global warming is the today’s important problem for all over the world. Due to the global warming, countries come face to face with lots of problems such as shortage of clean and usable water, erosion, usage of natural resources, and climatic problems. That’s why; in this paper, we proposed a model for selection of the utilization strategies for water resources in Turkey by using analytical hierarchy process and analytical network process based on linguistic terms under fuzzy environment. In this paper, the AHP/ANP is the useful applications in multi-criteria decision-making problems with numerous intangibles. For fuzzy AHP and fuzzy ANP analysis Chang’s (1996) extent analysis method are preferred to having the solutions. In the solution process, the linguistic levels of comparisons produced by the experts for each comparison are tapped in the form triangular fuzzy numbers to construct fuzzy pair-wise comparison matrices. The model is explained by an illustrative example and the results of both fuzzy AHP and fuzzy ANP methodologies are compared. The implementation of the system is demonstrated by a problem having four stages of hierarchy which contains different criteria and attributes.
