Abstract:This project analyzes different approaches for multi-criteria route selection for hazardous materials (hazmat) transportation on rail. Considering that hazmat transportation planning should regard many safety and risk factors, selecting a route for a shipment can be a challenging decision making problem. Furthermore, the safety and risk factors should be considered in an unbiased objective manner. Three unsupervised approaches are described route selection. A solution methodology is presented with these approaches. A set of numerical analyses is used to compare different approaches. Based on the results of the numerical analyses, it is discussed that, while each approach will output the best route based on a specific value, one of the approaches is more robust compared to the other two approaches. These approaches can be used by decision makers to select routes without a need for ranking and/or comparing various criteria. The total size of the described zip file is 51.1 MB. Files with the .xlsx extension are Microsoft Excel spreadsheet files. These can be opened in Excel or open-source spreadsheet programs. A file that ends in .m are files written in Objective-C. They help initialize variables and functions from other Objective-C source files. They can be viewed with Apple Xcode or using an iOS simulator. This file is used in conjunction with the .MAT file, which is a binary data container format used by MATLAB, an open source program.
