چکیده | ||
This paper proposes a neuro fuzzy model for analyzing the relationship between contractor’s qualifications and project quality in research projects. The proposed model has been implemented in a research-based organization, IIES. Cross validation method has been used in order to generate some set of data which have been used for different evaluations. The proposed neuro fuzzy model has dominated the linear regression model not only in average, but also in each data set. Moreover, the results showed a confident relationship between project quality and three criteria used for evaluating the contractor’s qualifications. | ||

چکیده [English] | ||
ایجاد و توسعة کیفیت در پروژهها دستاوردهایی چون افزایش رضایت کارفرما، کاهش هزینه، افزایش سود، و افزایش قدرت رقابت را دربردارد. در این پژوهش، با بهکارگیری مدلی عصبیـ فازی، ارتباط بین فاکتورهای ارزیابی توان فنی پیمانکاران پژوهشی و کیفیت اجرای این پروژهها تحلیل میشود. مدل توسعهدادهشده در مؤسسة مطالعات بینالمللی انرژی اجرا شد. برای افزایش قابلیت اتکا به نتایج، با استفاده از روش وارسی اعتبار، چندین مجموعهداده ایجاد و میانگین خطای تخمین در تکرارهای مختلف ارزیابی شد. رویکرد عصبیـ فازی خطیـ محلی نهتنها در حالت میانگین، بلکه در هر یک از تکرارها نیز قادر بود تخمینهای دقیقتری در مقایسه با رگرسیون خطی ارائه کند. نتیجة دیگری که از دادههای گردآوریشده به دست آمد وجود ارتباط معنادار بین کیفیت اجرای پروژهها و سه گروه شاخص از چهار گروه شاخص استفادهشده برای ارزیابی توان فنی پیمانکاران بود. | ||
