Group Decision Making for Emergency Response Based on Fuzzy Information

As emergency is always related to broad variety and complexity, group decision is needed to minimize the loss caused by emergent events. In emergency decision making, the decision makers may hesitate and lack knowledge. In order to solve this group decision making problem, a method that is based on incomplete intuitionistic judgment matrix is proposed for emergency management. In this paper, the incomplete intuitionistic judgment matrix is constructed to convey the information of experts in group decision making. The paper aggregates individuals' preferences into the group preferences through IFWG operator and selects the project by use of score functions. A case in emergency decision making in mudslide disaster is introduced, which demonstrates that the proposed method takes into full account of the characteristics of the group decision makers in emergency response and the application is feasible and efficient for emergency decision.
