Operating Characteristic Curve Analysis
topic
Operating characteristic curves plot the probability of lot acceptance against the true lot fraction defective or quality level for a given sampling plan, graphically revealing producer risk at the acceptable quality level and consumer risk at the rejectable quality level, enabling quantitative comparison and selection between alternative sampling plans for specific textile inspection applications.
Role
Provides the transparent visual tool for communicating sampling plan discrimination power to quality managers and procurement staff, enabling informed selection of sampling plans that appropriately balance inspection cost against protection level for specific textile product risk categories from commodity basics to safety-critical technical textiles.
