An emergency routing model based on fuzzy road connectivity

摘要

In this paper we study the path choice problem of material transportation in emergency based on the analysis of fuzzy concept. The effect of fuzzy factors on road is mainly considered to obtain an optimal calculation of path choice. A routing model with random probability for emergency rescue center is proposed with utilization of the theory of uncertain programming with fuzzy probability. The uncertain fuzzy random probability simulation, Bellman-ford algorithm and relaxation technique are used to solve the model. At last an example is given to demonstrate this method.
