چکیده

هدف: در اقتصاد رقابتی، عرضه محصولات در کمیت و کیفیت مناسب با حداقل هزینه در زمان تعیین شده، رمز بقا و موفقیت کسب و کار‌ها‌ محسوب می‌شود. زنجیره‌تامین کارآمد نقش مهمی در تضمین این موفقیت دارد. هدف تحقیق حاضر مدل‌سازی‌ شبکه زنجیره‌تامین یکپارچه برای دستیابی به حداکثر سود و حداقل کردن زمان پاسخگویی می‌باشد.
روش: باتوجه به اهمیت مدیریت زنجیره‌تامین و لجستیک در شرایط حاضر، طراحی و ‌بهینه‌سازی‌ شبکه زنجیره‌تامین یکی از مهمترین تصمیمات جهت ایجاد مزیت رقابتی می‌باشد و ‌بهینه‌سازی‌ تصمیمات در هر یک از سطوح تصمیم‌گیری را به دنبال دارد. این تحقیق شامل دو مرحله در سطح استراتژیک برای طراحی زیرساخت‌ها‌ی زنجیره‌تامین و سطح تاکتیکی برای برنامه‌ریزی عملیاتی زنجیره‌تامین انجام شده است که مدل‌سازی‌ ریاضی در این دو سطح فرموله شد. جهت تایید و اعتبار مدل پیشنهادی، از داده‌ها‌ی یک شرکت تولید کیس‌ها‌ی کامپیوتری استفاده شد و بعد از مدل‌سازی‌‌،‌ حل شده است.
یافته‌ها: تحقیق حاضر ابزاری برای ‌بهینه‌سازی‌ شبکه یکپارچه زنجیره‌تامین جهت استفاده مدیران و تصمیم گیرندگان در طراحی و بهره برداری شبکه‌ها‌ی تولید و توزیع را فراهم می‌آورد. اعتبار مدل پیشنهادی به‌دلیل بهبود در مقادیر توابع هدف نسبت به وضع موجود مورد بررسی و تایید قرار گرفت.
نتیجه‌گیری: نتایج نشان می‌دهد که مدل پیشنهادی می‌تواند رویکردی مناسب، برای تحقق یک برنامه‌ریزی موثر در یک زنجیره‌تامین در دو سطح استراتژیک و تاکتیکی فراهم کند و نیز مدیران می‌توانند با بکارگیری این مدل،‌ نسبت به پارامترهای عملکردی زنجیره تامین اطمینان حاصل نمایند.

چکیده [English]

Objective: In today's competitive economy, the supply of a product in an optimal quantity, quality and minimum cost at the right time are the pillars of success in a business. A continually efficient supply chain also plays an important role in solidifying this success. This research aims to model an integrated supply chain network to achieve maximum profit while minimizing the overall response time.
Methods: In view of the importance of supply chain management and logistics in recent times, the design and optimization of the supply chain network are extremely critical. This is mostly because, at each decision level, a well-optimized decision will result in a competitive advantage in the market.  In this research, the said design and optimization is explained in two levels; a strategic level where a supply chain is designed, and a tactical level dedicated to operational planning of the supply chain. In this paper, a mathematical model has been formulated for these levels. To verify and validate the proposed model, the acquired data from a computer case manufacturing company are examined and the outcomes were highlighted.
Results: This paper provides a tool in order to optimize the supply chain network. This tool can be useful for any manager or for those who are planning a supply chain from production or designing a product distribution network. Managers can also use this model to ensure the performance parameters of a particular supply chain.
Conclusion: The results show that the proposed model can provide an effective and easy-to-follow method to achieve a well-established plan in an integrated supply chain
