Finding the Shortest Path in a Network with Uncertain Paths Lengths

In this paper, we deal with the shortest path problem (SPP) on a graph in which a fuzzy number, instead of a real number, is assigned to each edge. Since fuzzy min operation based on the extension principle leads to nondominated solutions, w...

Critical Mass Task Identification in Projects

Critical Mass is a term that refers to some project activities which, even though not on the Critical Path, are very risky for in time project completion. Tasks potentially involved in critical mass are generally small, low prio...

Fuzzy Shortest Paths Approximation for Solving the Fuzzy Steiner Tree Problem in Graphs

In this paper, we deal with the Steiner tree problem (STP) on a graph in which a fuzzy number, instead of a real number, is assigned to each edge. We propose a modification of the shortest paths approximation based on the fuzzy shortest ...
