Abstract: In order to allocate the multiclass emergency resources of multiple rescue points to each accident point fairly and reasonably, firstly, the target planning method was used to establish a rescue time fixed multi-class resource dispatching model considering urgency degree and based on the model, a multi-point rescue resource scheduling model showing rescue time by interval numbers was established. A solution algorithm was designed to obtain the optimal resource scheduling scheme. And the effectiveness of the models was illustrated by examples.The results show that the emergency dispatching decision-making scheme based on multiple accidents and multiple resources can overcome greatly blindness of the scheduling, thereby optimize rescue scheme more effectively to reduce overall losses, for the introduction of both urgency degree and rescue time expressed by interval numbers.
