CAREER: Advancing Routing Methods in Hazardous Materials Transportation

该学院早期职业发展(Career)计划奖的目标是改进危险材料(危险物质)运输中的路线方法，以降低危险物质事故的风险，并为将当前的研究和实践提升到新的水平提供基本的基础。尽管风险管理理论取得了重大进展，但目前危险物质运输的研究和实践严重依赖于非常简单的风险衡量标准。对于规避风险的路由来说，这应该是不可接受的。此外，一个严重的数据不确定性问题没有得到很好的解决。该项目将提供应用于危险品运输的频谱风险度量(SRM)的基本理论和算法，这些可能从根本上改变当前政府规划中的研究和实践，以实现基础设施的更安全管理。该项目将在数据不确定性和时间依赖性下提供基于SRM概念的路由方法。SRM将被证明在低概率、高后果的应用中是有效的。如果成功，该项目将为危险物质布线提供最先进的风险缓解方法。由于这项研究将通过真实世界的案例进行测试，因此该结果具有很大的潜力应用于其他真实世界的危险物质运输问题。该项目还将对其他类似性质的交通问题产生影响。风险度量、模型和解决方案程序也适用于气体减排、供应链中断管理、人道主义物流和可靠网络的设计。该项目还将有助于建设研究和教学基础设施。基于网络的仿真系统将用于教学和测试研究思路，演示危险物质运输的性质，并培训实践者。该项目将教育和培训来自代表性不足群体的学生以及当地的高中生。

The objective of this Faculty Early Career Development (CAREER) Program award is to advance routing methods in hazardous materials (hazmat) transportation to mitigate the risk of hazmat accidents and provide fundamental building blocks to bring the current research and practice up to the next level. Despite significant advances in risk management theory, current research and practice in hazmat transportation heavily rely on very simple risk measures. This should be unacceptable for risk-averse routing. In addition, a serious issue of data uncertainty has not been well addressed. This project will provide essential theory and algorithms of Spectral Risk Measures (SRM) applied in hazmat transportation, which have the potential to radically change current research and practice in government planning for safer management of infrastructure. This project will deliver routing methods based on the SRM concept under data uncertainty and time dependency. SRM will be shown to be effective in low-probability, high-consequence applications. If successful, this project will provide the most advanced risk mitigation methods for hazmat routing. Since the research will be tested with real-world cases, the results have great potential to be applied to other real-world hazmat transportation problems. This project will also have an impact on other transportation problems of a similar nature. The risk measure, models, and solution procedures are also applicable to gas-emission reduction, supply-chain disruption management, humanitarian logistics, and the design of reliable networks. This project will also contribute to building research and teaching infrastructures. The web-based simulation system will be used for teaching and testing research ideas, demonstrating the nature of hazmat transportation, and training practitioners. This project will educate and train students from underrepresented groups as well as local high school students.
