Abstract: To enhance the effectiveness of collecting emergency material, a new decision making model is proposed and its algorithm was developed. Under the condition of urgent market purchase, the fuzzy decision making optimized model was put forward and, equivalently, the fuzzy chance-constrained model was established. When the parameters of model are triangle fuzzy number, the fuzzy chance-constrained condition could be equivalently turned into its clarified one. Also, a fuzzy simulation-based intelligent algorithm was deduced to solve the complicated optimization models. Finally, a numerical example shows that the method is valid.
