چکیده

مهندسی ارزش نگرشی خلاق به منظور بهینه‌سازی هزینه‌های چرخه عمر، صرفه‌جویی در زمان، افزایش سود، بهبود کیفیت، و استفاده بهینه از منابع می‌باشد. این روش مدیریتی در ایران نیز دارای سوابق متعدد در پروژه‌ها است، و بسیاری از دستگاه‌های اجرایی کشور در پروژه‌ها استفاده می‌کنند. پیاده‌سازی روش مهندسی ارزش در سازه‌های هیدرولیکی، این امکان را می‌دهد تا با رفتار نظام‌مند در جهت ایجاد تعادل بین هزینه‌ها و کارکرد پروژه، با اتکاء به خلاقیت و کار گروهی، در راستای حذف هزینه‌های زائد، افزایش راندمان و بهره‌وری مناسب‌تر پروژه‌ها، گام‌های مؤثر برداشته شود. اجرای این روش، نتایج کاملا مطلوب و ملموسی را در دنیا و حتی در ایران به‌جا گذاشته که از آن می-توان به سد تنظیمی مارون، کانال کنترل سیلاب رامشیر، تونل انحراف سد کوهرنگ، و موارد دیگر اشاره نمود. سدهای مخزنی پروژه‌های عظیم ملی و چند‌منظوره‌‌ای هستند که ذخیرة آب جهت مصارف شرب، کشاورزی، صنعت، تولید برق، مهار سیلاب‌ها، امور سیاحتی، فرهنگی و تفریحی از اهداف آنها است. عمده‌ترین معضلی که اغلب پروژه‌های بزرگ با آن مواجه هستند، عدم انجام مهندسی ارزش در آنها می‌باشد. هدف از انجام این تحقیق اعمال مهندسی ارزش در اجرای بدنه سد مخزنی کوثر گچساران واقع در استان کهگیلویه و بویراحمد می‌باشد. در انجام این تحقیق از روش‌شناسی مهندسی ارزش به کمک روش تحلیل سلسله مراتبی استفاده گردید. نتایج نشان داد که هزینه اجرای بدنه سد با کاربرد مهندسی ارزش، %47/8 معادل 8/5 میلیارد تومان کاهش یافت؛ از نظر زمان اجراء نیز حدود %25/20 کاهش ایجاد شد و %25/9 کیفیت اجراء نیز افزایش یافت.

چکیده [English]

Value engineering is a creative approach to optimizing life cycle costs, saving time, increasing profits, improving quality, and optimizing the use of resources. This management approach in Iran also has numerous project backgrounds, and many of the country's executive agencies use it in projects. Implementing a value engineering approach in hydraulic structures enables systematic behavior to balance project costs and performance, relying on teamwork and creativity to eliminate unnecessary costs and increase efficiency. And take more effective steps to make projects more efficient. Implementation of this method has yielded tangible results worldwide and even in Iran, from which the Maroun Regulatory Dam, the Ramshir Dam Control Channel, the Kuhrang Dam diversion tunnel, and more can be mentioned. Reservoir dams are major national and multipurpose projects that aim to conserve water for drinking, agriculture, industry, power generation, flood control, tourism, cultural and recreational activities. The major problem most large projects face is the lack of value engineering. The purpose of this research is to apply value engineering in the implementation of Kowsar Gachsaran reservoir dam located in Kohgiluyeh and Boyer Ahmad province. In this research, value engineering methodology was used by "Analytical Hierarchy Process" method. The results showed that the cost of implementation of dam body with value engineering application decreased by 8.47%, equivalent to 5.8 billion Tomans; about 20.25% decrease in execution time and 9.25% increase in performance quality.
