The Analysis of Water Supply Capacity Based on Analytic Hierarchy Process and Fuzzy Comprehensive Evaluation

摘要

Proposing solution to clean water shortage is of great importance to all citizens of the world. In this paper, we analyze and evaluate water supply capacity in a region based on building mathematical model by analytical hierarchy process (AHP) and fuzzy comprehensive evaluation. First of all, hierarchical structure consists of three layers, including target layer, criterion layer and sub-criterion layer. The weight matrixes of the first two layers are decided through AHP. Secondly, we describe factors in five degrees for determining five levels of capacity assessment. Fuzzy comprehensive evaluation is applied to acquiring the membership degree of five grades and judge the level of supply capacity rely on principle of maximum membership. Therefore, we are able to acquire water supply ability.
