Freight networks are a case of systems that multiple participants are composing interrelations along the complete supply chain. Their interrelations correspond to alternative behavior, namely, cooperation, non-cooperation and competition, while they are large-scale spatially distributed systems combining multiple means of transportation and the infrastructure and equipment typically utilized fo...

The paper presents a model for the collaboration among independent freight forwarding entities. In the modern highly competitive transportation branch freight forwarders reduce their fulfillment costs by exploiting different execution modes (self-fulfillment and subcontraction). For self-fulfillment they use their own vehicles to execute the requests and for subcontracting they forward the orde...

The Transportation Research Forum, founded in 1958, is an independent, nonprofit organization of transportation professionals who conduct, use, and benefit from research. Its purpose is to provide an impartial meeting ground for carriers, shippers, government officials, consultants, university researchers, suppliers, and others seeking exchange of information and ideas related to both passenger...

We study the joint problem of scheduling passenger and freight trains for complex railway networks, where the objective is to minimize the tardiness of passenger trains at station stops and the delay of freight trains. We model the problem as a mixed integer program and propose a twostep decomposition heuristic to solve the problem. The heuristic first vertically decomposes the train schedules ...

a r t i c l e i n f o We investigate the role of competitive transport markets in shaping the location of economic activity and the pattern of trade. In our model, carriers supply transport services for shipping manufactured goods, and freight rates are set to clear transport markets. Each carrier must commit to the maximum capacity for a round-trip and thus faces a logistics problem as there a...

From a societal perspective, it is desirable for all transportation users to pay their full social (private and external) costs. We estimate four general types of external costs for intercity freight trucking and compare them with the private costs incurred by carriers. Estimated external costs include: accidents (fatalities, injuries, and property damage); emissions (air pollution and greenhou...

This paper introduces a modelling and distributed simulation platform to be realized as a system of systems in the logistic domain. The presentation of the project context gives a sight onto the current progress of the research in the field of the networked enterprise modelling and in the implementation methods of information systems solutions, integrating the interoperability into the context ...

A systems perspective for regional strategic transportation planning (RSTP) for freight movements involves an understanding of Supply Chain Management (SCM). This thesis argues that private sector freight shippers and carriers do not simply need capacity improvements from the regional transportation system, but also a subtle understanding by public sector planners of their supply chain needs. T...

Ro-Ro transportation refers to a way of maritime transportation that uses Ro-Ro to bring goods and shipment together. Developments of Ro-Ro transport at home and abroad are outlined, and development process of China’s Ro-Ro transport is reviewed. The development and status of Ro-Ro transport of Yangtze River are analyzed in detail. Based on survey research, due to the change of road structure o...
