On solving fuzzy network flow problems

Network flow models provide a rich and powerful framework from which many engineering and management problems can be formulated and solved. A variety of applications, including the analyzes and design of computer networks, cable television networks, transportation systems, communication networks, project schedules, queuing systems, inventory systems, and manpower allocation, have been reported in the literature. Because of the ease with which systems can be modeled in network form, network analyzes are playing an increasingly important role in the description and improvement of operational systems. In this study, we investigate a fuzzy network flow problem in that the arc lengths of the network are fuzzy numbers.
