Decision analysis for transportation risk management

Modern transport systems are complex, therefore requiring highly effective management decision tools. These tools would aid in ranking alternatives, allocating resources, and certifying critical transportation operations. Existing methods may not accommodate the dynamics of changing environments and personnel threats. They also may not handle hard-to-quantify, disparate data, and may be unable to realistically estimate uncertainty. In this paper, the authors discuss a coordinated set of ongoing model development efforts to overcome such difficulties.
