چکیده مقاله :
هدف این مقاله ارزیابی کیفیت فرایند تولید با رویکرد نمودارهای کنترلی نوع X-R و قابلیت فرایند تولید می باشد. جامعه آماری تعداد 170نفرازمدیران ارشد، میانی و کاربران بخش کنترل کیفیت، پرسنل بخش تولید و کارکنان بخش پشتیبانی تولید شرکت بین‌المللی سیمان ایلام می‌باشد، که تعداد 118 نفر به عنوان نمونه و با استفاده از فرمول کوکران انتخاب شده اند. برای دست یابی به این هدف از رگرسیون خطی چند گانه استفاده شده است، که داده های مورد نیاز آن با استفاده از یک پرسشنامه استاندارد شده جمع آوری و سپس با استفاده از نرم افزار SPSS مورد تجزیه و تحلیل قرار گرفت و معلوم شد که نوع مواد اولیه و تجهیزات تولید این نمودارها را تحت تاثیر قرار می دهد، اما اپراتورها و تکنسین های نزدیک به فرایند تولید نمی توانند این نمودارها را تحت تاثیر قراردهند. همچنین نتایج نشان داد که مشتریان و بازار فروش، شرایط عملیاتی فرایند تولید و نمونه گیری نیز بر روی قابلیت فرایند تولید تاثیر گذار هستند.
چکیده انگلیسی:
The main purpose of this paper is to estimate the process quality estimation by using control charts type X-R and quality capability of the process. The population of research was 170 senior executives, middle managers, quality control, and support staff from Ilam cement manufacturing International Corporation. Using Cochran formula, 118 subjects were selected out of the total number of the population. Using multiple linear regression, random selection of the population was done. Then, the collected data, which was collected by using a standardized questionnaire were analyzed by using Spss software. Results showed that the type of material and equipment will affect the charts, but operators and technicians in the production process cannot affect the graphs. Also, the result showed that such factors as the customers and market, operational conditions, sampling are affecting the capability of the production process.
