Abstract:

In order to achieve fair dispatch of emergency materials at different disaster sites, inspired by the idea of accurate prevention and control in different regions and grades, a new fair scheduling model considering differentiated disaster classification was constructed with the aim of minimizing scheduling time and maximizing fairness of emergency materials distribution considering the minimum dissatisfaction of emergency materials at each disaster site at the same level as a benchmark to design fairness measurement index. Then, the model was solved by genetic algorithm, and simulation was conducted for the case of Hubei Province, the worst-hit area of the COVID-19 epidemic. The results show that this model can effectively solve the problem of fair material dispatch in differentiated disaster situations under the condition of material shortage. and while ensuring priority and focus of emergency materials distribution in worst-hit areas, it also takes into account the fairness of material dispatch at all levels of disaster areas.

Key words: disaster classification, emergency material dispatch, fairness, effectiveness, optimal model, emergency
