Application: Food Defense - Detailed Topological Mapping of Food Supply Chains
The capability to trace contaminated foods forward (to consumers) and backward (to providers) is needed for rapid recalls during biological, chemical or radiological food contamination events resulting from terrorist attacks. The difficulties in adequately characterizing food supply chain topologies present a major uncertainty in conducting risk assessments. Our goal is to develop capabilities that stochastically map food supply chains to support food defense and understand, model and articulate risks. A system-level understanding is necessary because food pathogens traverse multiple parts of the food delivery system.
- Supply chain topology varies markedly from one sector to another
- Supplier/customer relationships vary within sectors: some are enduring, others are market-based and highly transitory.
- Iinformation about supplier/customer relationships is often proprietary and difficult to obtain
- Knowledge about supply chain topology is generally limited to direct supplier and direct customer
- Spot-market relationships are ephemeral as suppliers may change daily
