A Two-Stage Hybrid Heuristic for Vehicle Routing Problem with Fuzzy Demands
A two-stage hybrid heuristic is presented for vehicle routing problem with fuzzy demands in this paper, the fuzzy credibility measure is employed to determine the credibility to send the vehicle to next node in the first stage, and a hybrid heuristics is proposed to determine a set of vehicle routes to minimize total costs in the second stage, especially for the additional distance and additional loading times. Finally the computational results are presented to show the high effectiveness and performance of the proposed approaches.
