摘要
This paper studies a bi-objective vehicle routing problem considering both travel cost and workload balance. Different from the existing research, the workload balance is calculated by workload variance and average value. We propose an improved multi-objective ant colony algorithm (MO-ACOTC) to eliminate distorted solutions and use a new global pheromone update strategy. The algorithm also designs a travel constraint mechanism to dynamically control the workload for each vehicle. The experimental results on traditional and revised instances show that the algorithm can obtain satisfactory solutions.
