双层规划在灾后应急物资调度中的应用综述.

In order to reduce property loss and human casualties, improve the satisfaction of the victims, this paper summarized the supplies scheduling problem under sudden disasters based on bi-level theory and from the perspective of emergency rescue. Focused on the emergency supplies scheduling, it carried out the review and discussion from the perspectives of post-disaster emergency status, emergency mate rial location-allocation, emergency supplies scheduling under different constraints, and the application of bi-level programming and swarm intelligence optimization algorithms in emergency supplies scheduling. The results showed that the research on the post-disaster emergency supplies scheduling currently focused on the single-level emergency network structure, and the objective function and constraint condition of the model were different from the actual situation. Combining the actual characteristics of the emergency supplies scheduling, this paper proposed some improvement suggestions. It considered the two-level emergency network structure, and then built a bi-level programming model to achieve joint optimization of the lower and upper level goals . [ABSTRACT FROM AUTHOR]
