ABSTRACT

Three level control charts are used to monitor processes, where the quality of products is characterized by classifying the product characteristic into three discrete levels. Recent studies have approved the advantages of using adaptive schemes rather than static one in monitoring such processes. In this paper, we develop adaptive control charts for monitoring three level products from an economic statistical perspective. Using numerical examples, we illustrate the performance of the proposed models. A sensitivity analysis is also carried out to investigate the effects of model parameters on the solution of the economic design by using the design of experiments (DOE) technique and multiple linear regression analysis method.

摘要

三级控制图用​​于监控过程，其中通过将产品特性分为三个离散级别来表征产品质量。最近的研究已经认可使用自适应方案而不是静态方案来监控此类过程的优势。在本文中，我们从经济统计的角度开发了用于监控三级产品的自适应控制图。我们使用数值例子来说明所提出模型的性能。还通过使用实验设计（DOE）技术和多元线性回归分析方法进行了敏感性分析，以研究模型参数对经济设计解决方案的影响。
