CAREER: Advancing Routing Methods in Hazardous Materials Transportation

该教师早期职业发展（CAREER）计划奖的目标是推进危险材料（hazmat）运输的路由方法，以减轻危险材料事故的风险，并提供基本的构建模块，将当前的研究和实践提升到一个新的水平。尽管风险管理理论取得了重大进展，但目前危险品运输的研究和实践严重依赖于非常简单的风险措施。这对于风险规避路由来说是不可接受的。此外，数据不确定性这一严重问题也没有得到很好的解决。该项目将提供应用于危险品运输的光谱风险度量（SRM）的基本理论和算法，这些理论和算法有可能从根本上改变政府规划基础设施安全管理的研究和实践。这个项目将提供路由方法的基础上SRM的概念下的数据不确定性和时间依赖性。SRM将被证明是有效的低概率，高后果的应用。如果成功，该项目将为危险品路由提供最先进的风险缓解方法。由于研究将与现实世界的情况下进行测试，结果有很大的潜力，可应用于其他现实世界的危险品运输问题。这一项目也将对类似性质的其他运输问题产生影响。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。基于网络的模拟系统将用于教学和测试研究思路，展示危险品运输的性质，并培训从业人员。该项目将教育和培训代表性不足群体的学生以及当地高中学生。

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.
