چکیده

هدف نهایی از هر بهبودی آن است که محصول یا خدمت با کیفیت بالاتری در اختیار مشتری قرار گیرد. متداولترین متدولوژی در شش سیگمای ناب ، متدولوژی DMAIC است .این متدولوژی بر مبنای پنج فاز : تعریف مساله، اندازه گیری و سنجش ، تحلیل ، بهبود و کنترل تعریف شده است. در این میان یکی از مهم ترین فازها ، فاز تحلیل است به دلیل آنکه در این فاز علل ریشه ای بالقوه با توجه به تاثیراتی که بر عوامل بحرانی کیفیت می گذارند، شناسایی و تعریف می شوند. هدف از این تحقیق سنجش میزان اثرگذاری متغیرها بر طولانی بودن زمان انجام فرآیند با استفاده مدل رگرسیون فازی بود. نتایج حاصل از اجرای مدل نشان داد که تمامی پنج متغیر شناسایی شده بر طولانی شدن زمان انجام فرآیند تاثیر گذار بوده و به ترتیب سه متغیر : مهارت ناکافی پرسنل ،خرابی ابزار و تجهیزات لازم و کمبود ابزار و تجهیرات لازم بیشترین تاثیر را بر متغیر مستقل دارند همچنین از میان این سه متغیر، متغیر مهارت ناکافی پرسنل، اثرگذارترین متغیر مستقل بر متغیر وابسته است. با توجه به نوع داده های تحقیق و تعداد متغیرها، مدل رگرسیون فازی تحلیل دقیقی از میزان اثرگذاری متغیرهای مستقل بر متغیر وابسته ارائه داد.

چکیده [English]

The ultimate goal of any improvements that provide higher quality product or service is customer. The most common methodology, Six Sigma and Lean Six Sigma methodology is DMAIC. This methodology based on five phases: defining the problem, measure, analyze, improve and control is defined. In the meantime one of the most important phases, phase analysis because in this phase of the root causes of potential due to its effects on the quality of critical factors are identified and defined. The purpose of this study is to assess the impact of process variables on the length of time in Lean Six Sigma methodology using fuzzy regression model was. The results of the study showed that all five variables known to influence the length of time to process. The results also showed that three variables: inadequate staff skills, and lack of necessary equipment, tools, and equipment breakdowns and tools necessary to have the greatest impact on the independent variable Also among these three variables inadequate staff skills, influential independent variable on the dependent variable. According to the research data and the number of variables, fuzzy regression model detailed and correct analysis of the impact of independent variables on the dependent variable was provided.
