Issue:
USDA’s Plant Protection and Quarantine (PPQ) division is accountable for reducing the pest threat to U.S. agriculture in a way that does not unduly restrict commerce. To accomplish this, PPQ is moving to better methods for determining not only what to inspect, but how to inspect it. Fundamentally, the issue is that USDA and DHS have limited resources available to inspect the vast amounts of people and cargo that enter the U.S. through ports of entry. The problem is to allocate these resources to conduct inspections as efficiently as possible in order to minimize the damages caused by pests imported into the U.S.
Objectives:
- Assess the performance of existing random sampling protocols using historical data from inspections.
- Formulate a mathematical decision support model that optimizes inspections at ports of entry based on pest arrival data and estimated economic damages caused by pests that enter the U.S.
- Demonstrate how the model can be employed to efficiently allocate inspection resources and sample arriving units using data from real-world case studies.
Value Proposition:
Mathematical tools, software, and results produced in this project will help the USDA and DHS minimize the damages caused by pests imported into the U.S.
