Abstract

This paper presents a new type of fuzzy shortest path problem on a network by ranking function. The proposed algorithm gives the fuzzy shortest path and fuzzy shortest path length in which type-2 trapezoidal fuzzy number is assigned to each arc length in a network. In this the ranking function is based on the statistical beta distribution. An illustrative example also included to demonstrate our proposed algorithm.
