Hybrid Meta-Heuristic Approaches for Vehicle Routing Problem with Fuzzy Demands
The vehicle routing problem with fuzzy demands at nodes is considered. The fuzzy credibility measure is developed to determine the credibility to send the vehicle to next node, and a hybrid mata-heuristics is proposed to determine a set of vehicle routes to minimizes vehicle number and total costs. Finally the computational results are presented to show the high effectiveness and performance of the proposed approaches.
