Application of Fuzzy Set Theory in Emergency Decision-making of Sudden Water Pollution Accident

摘要

Environment problem such as the frequent water pollution accidents has become one of the most notable emergency management problems for our government.When there is an emergency water pollution event, it is important to make an effective emergency decision according to the information of real-time event and the appropriate response can mitigate the environment pollution and costs.Because decisions may need to be taken very quickly and with limited information, the need for decision-making skills increases dramatically in emergencies. This paper primarily based on the fuzzy set theory and used the method to make a decision in complex situation of sudden water pollution accidents. The fuzzy set theory is used to represent the evaluation ratings of candidate items because of the information available can't be numerical. The approach can be used to help the decision maker choose the best emergency decisions.An example of choosing an effective emergency plan of water pollution accident is used to illustrate the method.
