Abstract
Events like the 9/11 terrorist attack on the World Trade Center and the 11-day work stoppage at 29 West Coast ports have exposed the vulnerabilities of a key element of America's economic infrastructure-business supply chains. To sustain business in today's new risk environment, it is necessary to assess the vulnerability of business chains and develop continuity and operational plans to mitigate consequences and assure continuation of critical processes. This paper reviews existing techniques used in decision making for risk analysis and presents a modeling and analysis framework for assessing business risk and evaluating safeguards to secure the supply chain.
