This paper aims to introduce the authors' study of route choice for vehicles transporting exigency materials based on the Traveling Salesman theory as to the principles of timely, security and economy of the material dispatching under exigency situation. To describes the above three decision-making parameters in accordance with mathematics theory, it is necessary to establish their objective functions through processing the dimensionless technique and weight aggregation so as to set up a mathematical model for evaluating the utility of prepared route, and model merges collected information according to the expectation utility attributes as well as to make the multi-attribute decision-making problems into the single one. In order to find a scientific vehicle route and define a scheduling decision-making method for a dispatched person in an emergency rescue material transporting center and enhance the response effect of the emergency rescue, it is necessary to choose and establish the highest expectation utility plan. And, finally, an example has been presented in the paper for demonstrative analysis. The results indicate that there is a distinct difference between the objective decision of the transporting dispatch under emergency situation and the objective decision of enterprise transport dispatch under normal state. The former belongs to the shortest path problem of graph theory, but it can't be directly solved by the shortest path model and Dijkstra method, because there remains a problem for multiple decision-making objectives. Thus, the method based on the multiple attribute decision-making theory in evaluating the utility of the prepared routing proves effective for the person to schedule vehicle routing. But, its comparative superiority remains to be further explored and discussed.
