Abstract

In the field of quality control, statistical process control (SPC) has its significance. The control charts are important tools of the SPC to observe the outputs of the production process. The cumulative sum (CUSUM) charting structure is one such technique that is designed to identify the medium and slight changes in the process parameters. In the literature, the assumption of normality is considered ideal for the control chart but in practice, many quality characteristics do not follow the assumption of normality. The current study proposes a class of CUSUM control charts for the location parameter of the process and investigates the performance of said location charts based on ranked set sampling (RSS) for quality characteristics having different environments. Different point estimators of location are considered in this study to develop the location control charts under normal, and a variety of non‐normal environments. The numerical results show that the newly designed schemes perform uniformly well than their competitors. A real‐life example linked with the manufacturing process is also provided for the practical implementation of the proposed scheme.

针对不同环境正确选择累积总和控制图的位置

在质量控制领域，统计过程控制（SPC）具有重要意义。控制图是 SPC 观察生产过程输出的重要工具。累积总和（CUSUM）图表结构就是这样一种技术，旨在识别过程参数的中等和轻微变化。在文献中，正态性假设被认为是理想的控制图，但在实践中，许多质量特性并不遵循正态性假设。本研究针对过程位置参数提出了一类 CUSUM 控制图，并研究了基于排序集抽样（RSS）的上述位置图在不同环境下的质量特性性能。本研究考虑了不同的位置点估计器，以开发正常环境和各种非正常环境下的位置控制图。数值结果表明，新设计的方案比同类方案表现一致。本研究还提供了一个与生产流程相关的真实案例，以便实际应用所提出的方案。

期刊介绍： Quality and Reliability Engineering International is a journal devoted to practical engineering aspects of quality and reliability. A refereed technical journal published eight times per year, it covers the development and practical application of existing theoretical methods, research and industrial practices. Articles in the journal will be concerned with case studies, tutorial-type reviews and also with applications of new or well-known theory to the solution of actual quality and reliability problems in engineering. Papers describing the use of mathematical and statistical tools to solve real life industrial problems are encouraged, provided that the emphasis is placed on practical applications and demonstrated case studies. The scope of the journal is intended to include components, physics of failure, equipment and systems from the fields of electronic, electrical, mechanical and systems engineering. The areas of communications, aerospace, automotive, railways, shipboard equipment, control engineering and consumer products are all covered by the journal. Quality and reliability of hardware as well as software are covered. Papers on software engineering and its impact on product quality and reliability are encouraged. The journal will also cover the management of quality and reliability in the engineering industry. Special issues on a variety of key topics are published every year and contribute to the enhancement of Quality and Reliability Engineering International as a major reference in its field.
