Many indexes and weights of the decision making in the water resources optimal distribution are qualitative. Therefore how to process these indexes and weights reasonably is the key to solve this kind of questions.In view of multi-attribute decisions-making question of water resources in the mix situation both of quantitative and precise indexes,this paper introduced the possibility concept by which different triangle fuzzy numbers can be mutually compared and the concept of fuzzy ratio scale.Let the represent quantitative indexes and the weights can be regularly expressed by the triangle fuzzy numbers in the decision-making.Through the research of synthesis appraisal method of the triangle fuzzy number decision-making matrix,under the decisional indexes was not unified probability distributions,this paper made the decisionmaking valuation results more reasonable and fitting the reality.The example calculation indicated that decision-making method in this paper was simple and feasible,the optimal decision scheme obtained was complety suitable to the ideas of the experts.
