Quick switching sampling (QSS) system comprises a pair of single sampling plans with switching rules and has been developed for lot disposition. The traditional QSS system for variables data only focused on products’ yield evaluation but ignored the additional loss caused when the quality deviated from the target value. Therefore, the purpose of this research is to develop a variables QSS system based on the loss-based capability index. To determine the designed plan parameters, a nonlinear optimization problem is constructed. The objective function is minimizing the required average sample number, and the constraints are set to satisfy the quality requests and allowable risks demanded by the producers and consumers, simultaneously. The performance of the proposed system is investigated and compared with other existing methods in terms of the operating characteristic, average sample number, and average run length. Finally, a practical case is presented for illustrating the applicability of the proposed plan.

快速切换抽样 (QSS) 系统包括一对具有切换规则的单一抽样计划，并已开发用于批量处理。传统的变量数据QSS系统只关注产品的良率评价，而忽略了质量偏离目标值时造成的额外损失。因此，本研究的目的是开发一个基于基于损失的能力指数的变量 QSS 系统。为了确定设计的计划参数，构建了一个非线性优化问题。目标函数是最小化所需的平均样本数，并设置约束以同时满足生产者和消费者要求的质量要求和允许风险。研究了所提出系统的性能，并在操作特性、平均样本数和平均运行长度方面与其他现有方法进行了比较。最后，提出了一个实际案例来说明拟议计划的适用性。
