Abstract: Reasonable arrangement of distribution route of fresh agricultural product can effectively guarantee the freshness of products, improve the distribution efficiency, and reduce the distribution cost. In practical distribution, the road condition is an important factor affecting the arrangement of the distribution route. According to the different road conditions, the speed characteristic models are set up. Meanwhile, considering the perishable and vulnerable characteristics of fresh agricultural products, the function of time window penalty cost and the function of customer satisfaction are established. Based on the comprehensive consideration of factors, such as road condition, time window and fresh consumption, a multi-objective optimization model of fresh agricultural product distribution route is constructed, which minimizes distribution cost and maximizes customer satisfaction. Motivated by simulated annealing thinking, an improved adaptive genetic algorithm is proposed. The feasibility and effectiveness of the constructed model and the proposed algorithm are verified by simulation experiments.

Key words: fresh agricultural products, vehicle routing, road condition, adaptive genetic algorithm
