چکیده

یک نوع خاص از ارزیابی انطباق که گاهی اوقات بازرسی نامیده می‌شود، جهت تعیین اینکه یک محصول الزامات معینی را برآورده می‌سازد، به اندازه‌گیری به عنوان منبع اصلی اطلاعات متکی است. در هر اندازه‌گیری ‌نتیجه به‌دست‌آمده همیشه دارای عدم‌قطعیت می‌باشد. به دلیل وجود عدم‌قطعیت در نتایج اندازه‌گیری همواره ریسک تصمیم‌گیری غلط در فرایند ارزیابی انطباق وجود دارد. تاکنون در خصوص نحوه ارزیابی این ریسک‌ها مطالعات زیادی انجام شده است. در بیش‌تر این مطالعات به ارزیابی ریسک‌های تصمیم‌گیری از منظر تولیدکننده با استفاده از دقت اندازه‌گیری و تغییرپذیری فرایند تولید پرداخته شده و مطالعات اندکی در خصوص ریسک‌های تصمیم‌گیری از منظر مصرف‌کننده با در نظر گرفتن عدم‌قطعیت اندازه‌گیری و تغییرپذیری فرایند تولید انجام شده است. بر این اساس در این مقاله همراه با یک مطالعه موردی نحوه ارزیابی ریسک‌های تصمیم‌گیری غلط از دو منظر تولیدکننده و مصرف‌کننده با استفاده از عدم‌قطعیت اندازه‌گیری و تغییرپذیری فرایند تولید به روش احتمال توام تشریح می‌شود و گزینه‌های مختلفی برای مقابله با این ریسک‌ها ارائه و بررسی می‌شوند. نتایج این پژوهش نشان می‌دهد که استفاده از عدم‌قطعیت اندازه‌گیری به‌جای دقت اندازه‌گیری در ارزیابی ریسک‌های تصمیم‌گیری غلط، براورد واقع‌بینانه‌تری از ریسک‌ها را ارائه می‌دهد و می‌توان با اصلاح قواعد تصمیم‌گیری در فرایند ارزیابی انطباق پیامدهای ناشی از این ریسک‌ها  را تعدیل نمود.

چکیده [English]

 special type of conformity assessment, sometimes called an inspection, relies on measurement as the primary source of information to determine whether a product meets certain requirements. In any measurement, the result obtained always has uncertainty. Due to the uncertainty in the measurement results, there is always the risk of making wrong decisions in the conformity assessment process. So far, many studies have been done on how to assess these risks. Most of these studies have evaluated the decision-making risks from the producer perspective using measurement accuracy and variability of the production process, and few studies on decisionmaking risks from the consumer perspective have taken into account the measurement uncertainty and variability of the production process. Accordingly, in this article, along with a case study, how to evaluate the risks of wrong decision-making from both producer and consumer perspectives using measurement uncertainty and variability of the production process by the probability method is described and various options to deal with these risks are presented and examined. The results of this study show that the use of measurement uncertainty instead of measurement accuracy in assessing wrong decision risks, provides a more realistic estimate of risks and can be adjusted by modifying the decision rules in the assessment process of compliance with the consequences of these risks.
