Enterprise-wide Simulation and Analytical Modeling of Comprehensive Freight Movements

这项拟议的工作将开发一个多模式网络分析，以模拟电子商务和不同的货运供应链成本对货物移动的影响。将模拟主要的物理行动，包括信息交换和将货物从来源转移到目的地所需的决策。将开发一种方法，用于模拟大量单独的车辆货运，并将它们分配到美国卡车水上航空货运网络中的特定链路。在供应链管理框架内，信息和现金流将纳入网络分析。创建于20世纪60年代的S，互联网已经成为一种开放的、廉价的、全球可用的与世界其他地区快速通信的手段。在线互联网交易现在是一种主要的商业活动形式。这种向电子商务的快速过渡最终对美国运输业意味着什么，还有待观察。它可能会在国内和国际产品供应链上引发一些深刻的变化，导致一些重要的新的货运模式，这些模式只能通过将物理网络和信息网络相互联系来模拟。这项研究的重点将是发展一个健全的理论基础，使用文献中的信息作为概念验证的指南，而不是经验分析。该奖项是在工程探索研究交通运输业(ETI)计划征集下颁发的。

The proposed work will develop a multimodal network analysis to simulatethe effects of e-commerce and different freight supply chain costs on themovement of goods. Major physical actions, including information exchange,and decisions required to move goods from source to destination will besimulated. A method will be developed for simulating large numbers ofindividual freight shipments by vehicle and for assigning them to specificlinks in the US truckrailwaterair freight transportation network. Within asupplychain management framework, information and cash flow will beincorporated into the network analysis. Created in the 1960's, theInternet has become an open access, inexpensive, and globally availablemeans for rapid correspondence with the rest of the world. On-lineInternet trading is now a major form of business activity. What this rapidtransition to e-commerce ultimately implies for the U.S. transportationsector remains to be seen. It is likely to initiate some profound changesin both domestic and international product supply chains, leading to someimportant new patterns of freight movement which can only be modeled byinter-relating the physical and information networks. The focus of thisresearch will be on the development of a sound theoretical base usinginformation in the literature as a guide to proof of concept instead of anempirical analysis.This award is made under the Exploratory Research on Engineering theTransport Industries (ETI) program solicitation.
