The greatly studies show that it is quite appropriate to use fuzzy theory to solve the shortest path problem. This paper analyses the general method of dealing with the shortest path problem by using discrete fuzzy arc length, and points out the issue of such methods. As carrying on various kinds of operation between the fuzzy numbers and sets, some information will be lost. In this paper, some related...
The shortest path problem (SPP) is currently being greatly studied in fuzzy sets and systems area. Previously published algorithms and methods for the fuzzy shortest path problem based on discrete or continuous types fuzzy sets of fuzzy arc lengths. However, to present an arc real length in vague set is more reasonable than in fuzzy set. Moreover,carrying on various kinds of operation between the...
