Abstract:

As a kind of special emergency resource, rescue workers play an important role in disaster relief. In order to overcome the defects of traditional assignment models, a multi-objective model is proposed with the rescue team's characteristics taken into consideration. Firstly, based on the definition of rescue team's attributes, a utility matrix is developed to meet the disaster needs of different rescue teams. Secondly, three priority scheduling strategies are defined in accordance with the principle of "Burden-Benefit accord", and the influence of three priority scheduling strategies on rescue time and rescue effect are analyzed. Furthermore, the designed NSGA-Ⅱ, CMETRIC and fuzzy logic methods are developed to solve the above model. Finally, a case of emergency rescue in Wenchuan earthquake is conducted to illustrate the efficiency and advantages of the proposed method. The results show that in the process of disaster relief, it is reasonable that considering the characteristics of rescue team, and the three priority scheduling strategies outperform the others, however, which of these three priority strategies is most appropriate for the specific disaster situation depends on the maximum rescue time allowed by the disaster.
