摘要

Acceptance sampling is widely used in practice to verify product quality and reliability. Recently, variable quick-switching sampling systems (VQSSs) have gained attention in product verification, especially in high-cost inspections, due to their enhanced cost-effectiveness. Existing VQSSs implement normal and tightened inspections by adjusting the required number of failures in lifetime tests or modifying acceptance criteria, enabling lot disposition based on previous lot outcomes. This paper introduces an adaptive VQSS (AVQSS) model that builds on traditional VQSS by simultaneously adjusting both the required number of failures and acceptance criteria to construct normal and tightened inspections. By integrating AVQSS with the lifetime performance index, we provide a more robust framework for quantifying and evaluating product reliability. Our investigation demonstrates that AVQSS achieves greater cost-effectiveness than existing VQSSs, with these advantages being particularly pronounced in high-cost lifetime testing. Furthermore, AVQSS maintains balanced discriminatory power between lot reliability levels while maximizing cost-efficiency, which is expected to further streamline sampling inspections in practical applications. To illustrate its practical value, we also apply the proposed AVQSS to a real-world case study.
