Flood Regulation Model of Douhe Reservoir Based on Fuzzy Matter Element

摘要

The selection of flood regulation plan is a multi-objective decision making, with strong fuzziness and randomness. In this paper, through research, problems regarding flood regulation plan is analyzed, evaluation index system is created in order to use bargaining right, objective and subjective weight to determine the evaluated targets' weight, with the help of fuzzy matter element model to give combined assessment to each candidate plan. It is proved that the method bears in mind the incompatibility and fuzziness of assessments and is able to assist decision executions comprehensively. It is well utilized in the flood regulation process of Douhe Reservoir.
