【摘要】：物流业正迈进全球一体化、营运信息化的快速发展阶段，物流企业竞争的胜负已不仅仅完全取决于企业本身，而在很大程度上取决于企业所在供应链的性能。运输作为供应链中最重要的部分，企业合理优化运输任务系统，能极大的提高企业的经济效益。运输费用是物流体系以及供应链成本的重要组成部分，一个成功的运输任务体系，一定离不开一个高效的、低运输费用的运输链网络。 Agent是一种在协作系统或者是分布系统中能持续自主决策，并完成指定任务的计算实体，即智能体。它所具备的特征被公认为适用于各类复杂系统的研究。物流运输问题作为多目标复杂问题，，引入多Agent技术对运输链实时仿真，是一种新兴的解决运输决策问题的方法，可以为实际运输提供决策依据，具备很好的理论意义和实用价值。本文从运输链的视角出发，分析了当前物流运输业务的结构，针对运输链作业过程，建立了基于多Agent的运输链仿真模型。该模型具有一定重用性和通用性，能用来分析与运输相关的因素或是政策对运输决策的影响。然后将该模型应用于汽车物流实际案例中，研究了运输时间、运输费用以及同时考虑运输时间和运输费用等因素时，对运输路径决策的影响，同时还研究了燃油附加税、CO2税等相关政策对实际运输路径决策的影响。
[Abstract]:The logistics industry is stepping into the global integration, the rapid development stage of operation information, logistics enterprises' competition is not only depends on the enterprise itself. Transportation, as the most important part of the supply chain, is the most important part of the supply chain, and the enterprise optimizes the transportation task system reasonably. Transportation cost is an important part of logistics system and supply chain cost, a successful transportation task system, must be inseparable from an efficient. Low cost transport chain network. Agent is a kind of computing entity that can make decision independently and accomplish the specified task in the cooperative system or the distributed system. That is, agent. Its characteristics are recognized as suitable for the study of various complex systems. Logistics transportation problem as a multi-objective complex problem, the introduction of multi-#en0# technology to real-time simulation of transport chain. It is a new method to solve the transportation decision problem. It can provide the decision basis for the actual transportation and has good theoretical significance and practical value. From the perspective of transportation chain, this paper analyzes the structure of current logistics transportation business, aiming at the operation process of transport chain. The simulation model of transport chain based on multiple Agent is established, which has certain reusability and generality. It can be used to analyze the influence of transportation factors or policies on transport decision. Then the model is applied to the actual case of automobile logistics, and the transport time is studied. The influence of transportation cost and factors such as transportation time and transportation cost on transportation path decision is also studied. The influence of related policies such as fuel surtax and CO _ 2 tax on actual transportation path decision is also studied.
