ABSTRACT
Based on summarising the current situation of related theories at home and abroad, we put forward the research content of this paper, that is, research on vehicle routing optimisation in the period of natural disaster rescue emergency. The paper determines the objective function of the emergency period and establishes a model based on the function. During the modelling process, we use dimensionless method and multi-objective optimisation to transfer the multi-objective problem into a single-objective problem. Finally, we get the total weights and put them into the emergency network, then we are able to transfer the emergency vehicle routing problem into shortest road problem. And we can use Lingo to solve this problem. In this paper, we also regard the rescue of Wenchuan earthquake is an example used to illustrate and apply the method and make some recommendations.
