THE FUZZY ANT SYSTEM FOR THE VEHICLE ROUTING PROBLEM WHEN DEMAND AT NODES IS UNCERTAIN

Abstract

In some distribution systems, only approximate values of demand at nodes are known. In this research, the new type of the intelligent vehicle routing system has been developed. Demand at the nodes is treated as a fuzzy number and actual demand value is known only after the visit to the node. The model developed is based on the Fuzzy Arithmetic Rules, Fuzzy Logic and Ant System. Numerical experiments indicate that the developed Fuzzy Ant System is very promising.
