The transportation sector continues to adopt telecommunication and information technologies that provide real-time information to enhance productivity and performance. Recently these technologies have started to modify the way contracts are negotiated, by enabling demand and supply to be matched dynamically through market mechanisms. A significant change may be taking place in the structure of the transportation market, with the development of auction markets for transportation services, in the form of Internet sites that match shipments (shippers demand) and transportation capacity (carriers offer). The development of these virtual hubs and their characteristics have fundamental implications for the methodologies to both analyze the performance of such systems, as well as to incorporate these mechanisms in the operational decisions of carriers and shippers (and/or their agents).This research project will develop modeling techniques to analyze carrier-shipper interaction in the context of an online electronic transportation marketplace. Carriers and shippers are modeled as entities that determine their interaction with other agents and with their environment on the basis of history (experience), learning, expectations about future consequences of current actions, and evolving strategies. In addition to developing methods to support individual player strategies in a non-cooperative decision environment with varying degrees of information sharing, the study investigates overall market behavior, its efficiency and resulting shipper service levels under different market settings and individual player strategies. The results obtained are of relevance to both shippers and carriers operating in online markets, as well as government agencies and policy-making entities concerned with the structure and efficiency of the transportation system. To take advantage of potential opportunities in real-time auction markets, both shippers and carriers require a new level of mastery of real-time information about not only the state of their shipments and./or fleets, but also about the entire system transacted through those markets. The methodological contributions of the research have applications that extend beyond the realm of transportation systems to include various infrastructure services that are distributed over space and time.

运输部门继续采用电信和信息技术，这些技术提供实时信息以提高生产力和绩效。最近，这些技术已经开始通过市场机制动态匹配的需求和供应来修改合同谈判的方式。运输市场的结构可能会发生重大变化，随着交通服务拍卖市场的发展，互联网站点的形式与运输（托运人需求）和运输能力（运营商提供）的形式。 这些虚拟枢纽的开发及其特征对分析此类系统的性能以及将这些机制纳入运营商和托运人（和/或其代理商）的操作决策的方法具有根本性的影响。这项研究项目将开发建模技术，以在在线运输市场上分析载流相互作用。运营商和托运人被建模为实体，这些实体决定了其与其他代理商的互动以及与其环境的互动，并基于历史（经验），学习，对当前行动的未来后果的期望以及不断发展的策略。除了开发在具有不同信息共享程度的非合作决策环境中支持各个玩家策略的方法外，该研究还调查了整体市场行为，其效率以及在不同的市场环境和个人参与者策略下的托运人服务水平。获得的结果与在在线市场中运营的托运人和运营商以及与运输系统的结构和效率有关的政府机构和政策制定实体均相关。为了利用实时拍卖市场的潜在机会，托运人和运营商都需要新的掌握实时信息的新水平，不仅是其货运状况和船队的状态。 研究的方法论贡献具有超出运输系统领域的应用程序，包括在时空和时间上分布的各种基础设施服务。
