چکیده

قابلیت فرآیند یکنواختی و تکرارپذیری یک فرآیند را باتوجه به نیازمندی­های مشتری و مشخصات محصول اندازه­گیری می­کند. توسعه نمودارهای کنترل برای قابلیت فرآیند، راه جامع­تری برای پایش عملکرد فرآیند ارائه می­دهد. در این تحقیق، یک نمودار کنترل برای پایش قابلیت فرآیند فرآیندهایی که از توزیع لجستیک پیروی می­کنند، ارائه شده است. در این نمودار کنترل، بازده فرآیند براساس پارامترهای توزیع فرآیند پایش می­شود. همچنین، در این تحقیق رویکردی برای افزایش توان تشخیص نمودار کنترل پیشنهاد شده است. مزیت نمودار کنترل پیشنهادی توانایی آن در پایش همزمان پارامترهای توزیع فرآیند است. عملکرد نمودار کنترل از طریق آزمایش‌های شبیه‌سازی براساس شاخص‌های میانگین طول اجرا (ARL) و انحراف استاندارد طول اجرا(SDRL)  ارزیابی می‌شود. باتوجه به نتایج شبیه‌سازی، نمودار کنترل پیشنهادی می­تواند عملکرد مؤثری در تشخیص شرایط خارج از کنترل داشته باشد.

چکیده [English]

Process capability measures the uniformity and repeatability of a process with regard to customer requirements and product specifications. Developing control charts for the capability of a process offers a more comprehensive way to monitor the process performance. In this research, a control chart is developed for the process capability of processes that follow Logistic distribution. In this control chart, process yield is monitored based on the process distribution parameters. A procedure is proposed to enhance the detection power of the control chart. The advantage of the proposed control chart is its ability to simultaneous monitoring of process distribution parameters. The performance of the control chart is evaluated through simulation experiments based on the average run length (ARL) and standard deviation of run length (SDRL) indices. According to simulation results, the proposed control chart can effectively detect out-of-control conditions.
