Reliable container line supply chains

Container line supply chains, based on a near-frictionless international transport belief, have contributed to economic prosperity and also rendered themselves uniquely vulnerable to various risks. 9/11 terrorists attacks, the lock-out of American West Ports and the global breakout of SARS disease have gradually shown that a) the safety and reliability in the chains are facing an unprecedented challenge and b) traditional engineeringbased risk assessment methods are inadequate to deal with the threats from variational environments, especially in the era of terrorism rampancy. The purpose of this paper is, therefore, to develop a conceptual risk assessment model for container line supply chains based on a modified Formal Safety Assessment (FSA) methodology that takes risks from vulnerability rather than only hazards into account. It gives particular emphasis on the analysis of the threats with a high level of uncertainty from both safety and economic viewpoints. The advantages of the vulnerability-based risk analysis approach to the hazard-based one are clarified and both engineering-based and managerial risk assessments are also discussed.     

Simulation studies of information propagation in a self-organizing distributed traffic information system

This paper investigates the feasibility of a self-organizing, completely distributed traffic information system based upon vehicle-to-vehicle communication technologies. Unlike centralized traffic information systems, the proposed system does not need public infrastructure investment as a prerequisite for implementation. Due to the complexity of the proposed system, simulation is selected as the primary approach in the feasibility studies. A simulation framework is built based on an existing microscopic traffic simulation model for the simulation studies. The critical questions for building the proposed market-driven system are examined both from communication requirements and traffic engineering points of view. Traffic information propagation both in freeway and arterial networks via information exchange among IVC-equipped vehicles is tested within the simulation framework. Results on the probability of successful IVC and traffic information propagation distance obtained from the simulation studies are generated and analyzed under incident-free and incident conditions for various roadway formats and parameter combinations. Comparisons between the speed of the incident information wave and the speed of the corresponding traffic shock wave due to the incident are analyzed for different scenarios as the most crucial aspect of the information propagation as a potential foundation for application in such a decentralized traffic information system.
