多式联运订单合并运输决策模型研究
Research on multimodal orders consolidation transportation decision-making model
摘要
Abstract
To improve the quality of multimodal order combination transportation decision-making,enhance the full load ratio of transport vehicles and optimize the transportation structure,we build a decision-making model of order combination transportation with minimum total cost as the goal.The designed genetic algorithm improves the population updating mechanism and encodes the path node,the transportation mode and the transportation frequency of each order respectively.Our results show increasing carbon emission cost is conducive to the transformation of transport structure to low-carbon transport mode and proper carbon tax has obvious effect on the optimization adjustment of transport structure and cost optimization control.The average full load ratio decreases with the increase of penalty cost per unit time,but it has different effects on full load ratio of different modes of transportation.Order consolidation cuts not only the number of vehicles in service,but also the total costs.the cost reduction is more obvious with the growing number of orders.关键词
