چکیده

مهندسی ارزش یکی از ابزارهای خلق و بهبود ارزش می‌باشد که ضمن کاهش هزینه‌های غیرضروری و حفظ کارکرد اصلی، منجر به افزایش کارایی می‌گردد. امروزه این تکنیک به‌منظور کاهش هزینه در صنایعی همچون برق که با هزینه‌های بالا مواجه هستند استفاده می‌شود. از آنجا که در بسیاری موارد، کارایی پایین در زنجیره تأمین این صنعت منجر به افزایش هزینه‌ها‌ می‌گردد، لذا بهره‌گیری از گام‌های مهندسی ارزش بسیار اثربخش خواهد بود. در این مقاله سعی شده تا با ترکیب مبحث زنجیره ارزش و روش‌های نوین تصمیم‌گیری چندشاخصه نسبت به شناسایی و اولویت‌بندی راهکارهای کاهش هزینه در زنجیره تأمین کابل و تجهیزات جانبی نیروگاه سیکل ترکیبی سیرجان (گل گهر) اقدام شود. بدین منظور نخست راهکارهای نهایی کاهش هزینه پس از برگزاری جلسات متعدد با خبرگان تیم مهندسی ارزش پروژه شناسایی شدند. سپس این راهکارها با معیارهایی که از ادبیات تحقیق استخراج و با نظر خبرگان تیم مهندسی ارزش پروژه (در قالب فرآیند دلفی فازی) تعدیل و نهایی شد، مورد ارزیابی قرار گرفت. معیارهای نهایی و هریک از زیرمعیارها با روش سوآرا وزن‌دهی شدند. سپس وزن نهایی هریک از زیرمعیارها محاسبه شد. در ادامه برای اولویت‌بندی راهکارهای نهایی از روش آراس خاکستری بهره گرفته شد. پس از اولویت‌بندی راهکارها، راهکار دوازدهم (کاهش زمان سفارش تا خرید و تحویل از طریق اصلاح رویه خرید)، به‌عنوان بهترین راهکار برای کاهش هزینه و در نتیجه افزایش کارایی زنجیره تأمین موردنظر شناسایی شد.

چکیده [English]

Value engineering is one of the tools to create and improvement value while reduces unnecessary costs and keeps the original function, leads to increased efficiency. Today this technique used to reduce the cost in industries that are facing high costs such as the electricity industry. The evidence and expert’s opinion implying that many factors causing costs in the industry is related to the supply chain the low efficiency in the supply chain, resulting in increased costs. So to increase performance and reduce costs, the research was conducted aimed to identify and prioritize solutions reduce costs in the supply chain for cables and accessories combined cycle power plant Sirjan (Gol Gohar), who has a major role in the country's electricity supply. The final solutions for cost reduction after holding several meetings with experts of the project value engineering team were identified. Then these solutions were evaluated with criteria extracted of the research literature and opinions of experts of the project value engineering team were moderated and finalized. The final criteria and each of the sub-criteria were weighted by SWARA. Then final weight was calculated for each of the sub-criteria. In order to prioritize final solutions we used ARAS-G. After prioritizing solutions, solution the twelfth (reducing the time of order up to purchase and deliver through the reform procedures purchase), as the best solution was identified to reduce costs and thus increase performance supply chain target
