An analytical framework for the design and analysis of continuous sampling plans (CSP) to manage import and export pathway risk

Overview

The Compliance-Based Intervention Scheme (CBIS) is used at the Australian border. CBIS is a type of continuous sampling plan (CSP). It uses a risk-based intervention approach to manage imports while reducing regulatory costs. Importers who consistently meet biosecurity requirements can qualify for reduced intervention rates.

This report provides new mathematical modelling techniques for continuous sampling plans. These methods support the design and monitoring of CBIS and other CSP plans. These new approaches are flexible, accurate and fast. They allow for risk and cost comparisons of CSP schemes used in Australia and overseas.
