Multi-criteria inoperability analysis of commodity-specific dock disruptions at an inland waterway port

Decision making for managing risks to critical infrastructure systems requires accounting for the widespread impacts of disruptions that render these systems inoperable. This paper integrates a dynamic risk-based interdependency model with a weighted multi-criteria decision analysis technique to evaluate discrete resource allocation alternatives to improve port preparedness. Dock-specific resource allocation provides a more tangible assessment of the effect of preparedness planning on particular commodities that flow through an inland waterway port. Uncertainty is accounted through the use of probability distributions of total expected loss per industry. We analyze a set of discrete allocations options of preparedness plans of a study of the Port of Catoosa in Oklahoma along the Mississippi River Navigation System.
