Finding shortest path in networks is an realistic and interesting problem. The lengths of the edges in a short path problem are naturally imprecise due to the inevitable uncertainty in real application. Hence, it is necessary to develop new methods to handle fuzzy shortest path finding problems. In this short paper, a novel and simple method to solve fuzzy shortest path finding is proposed. The dynamic programming algorithm is generalized to fuzzy environment with the use of graded mean representation of fuzzy numbers. An numerical example on transportation in network is used to illustrate the efficiency of our proposed method. © 2011 CRL Publishing Ltd.
