چکیده
هدف: هدف این مقاله، بررسی یکی از چالش‌های اساسی است که سازمان‌ها در عصر حاضر با آن روبرو هستند؛ کنترل انتشار دی‌اکسید‌‌کربن. این مطالعه قصد دارد مدلی برای طراحی شبکه زنجیره‌تامین سبز ارایه دهد که هزینه‌های کلی شبکه را به حداقل برساند و در عین‌حال، ملاحظات زیست‌محیطی را نیز مد‌نظر قرار دهد. این پژوهش در پی دستیابی به یک بهینه‌سازی متعادل میان هزینه‌ها، انتشار کربن و سطح خدمات در حوزه مدیریت زنجیره‌تامین است.
روش‌شناسی پژوهش: این مطالعه یک مدل بهینه‌سازی یکپارچه نوآورانه ارایه می‌دهد که جنبه‌های اقتصادی، زیست‌محیطی و رضایت مشتری را در شبکه زنجیره‌تامین در‌نظر می‌گیرد. مدل ریاضی به‌صورت یک مساله برنامه‌ریزی غیرخطی مختلط-عدد صحیح فرمول‌بندی شده است. یک روش دقیق برای حل مدل به‌کار گرفته شده که با استفاده از نرم‌افزار بهینه‌سازی GAMS کدنویسی و پیاده‌سازی شده است. کارایی و اثربخشی مدل از طریق مثال‌های عددی و تحلیل داده‌ها مورد اعتبارسنجی قرار گرفته است.
یافته‌ها: نتایج، توانایی مدل را در بهینه‌سازی ابعاد اقتصادی و زیست‌محیطی در کنار حفظ سطح بالای خدمات و رضایت مشتری نشان می‌دهد. مثال‌های عددی که برای مسایل با ابعاد مختلف حل شده‌اند، کاربردی و موثر‌بودن رویکرد پیشنهادی را تایید می‌کنند. یافته‌ها به تعادل‌های میان کاهش هزینه، کاهش انتشار کربن و کیفیت خدمات در شبکه‌های زنجیره‌تامین اشاره دارند.
اصالت/ارزش افزوده علمی: این پژوهش با ارایه یک مدل بهینه‌سازی یکپارچه جدید که به‌طور هم‌زمان به کارایی هزینه، پایداری زیست‌محیطی و رضایت مشتری در طراحی زنجیره‌تامین سبز می‌پردازد، به حوزه علمی کمک می‌کند. استفاده از رویکرد برنامه‌ریزی غیرخطی مختلط-عدد صحیح و پیاده‌سازی آن در نرم‌افزار GAMS، چارچوبی قوی برای حل مسایل پیچیده زنجیره‌تامین فراهم می‌کند. این مطالعه بینش‌های ارزشمندی را برای سازمان‌هایی ارایه می‌دهد که قصد دارند به اهداف پایداری دست یابند، در حالی‌که به قابلیت‌های اقتصادی و عملیات مشتری‌محور خود پایبند هستند.

چکیده English

Purpose: The purpose of this paper is to address one of the most critical challenges faced by organizations today: controlling carbon dioxide emissions. This study aims to provide a model for designing a green supply chain network that minimizes total network costs while incorporating environmental considerations. The research seeks to achieve a balanced optimization of costs, carbon emissions, and service levels in supply chain management.
Methodology: This study proposes a novel integrated optimization model that considers economic, environmental, and customer satisfaction aspects within the supply chain network. The mathematical model is formulated as a Mixed-Integer Nonlinear Programming (MINLP) problem. An exact method is employed to solve the model, which is coded and implemented using GAMS optimization software. The efficiency and effectiveness of the model are validated through numerical examples and data analysis.
Findings: The results demonstrate the model's ability to optimize both economic and environmental dimensions while maintaining high service levels and customer satisfaction. The numerical examples, solved for problems of varying dimensions, confirm the practicality and effectiveness of the proposed approach. The findings highlight the trade-offs between cost minimization, carbon emission reduction, and service quality in supply chain networks.
Originality/Value: This research contributes to the field by presenting a new integrated optimization model that simultaneously addresses cost efficiency, environmental sustainability, and customer satisfaction in green supply chain design. The use of a mixed-integer nonlinear programming approach and its implementation in GAMS provides a robust framework for solving complex supply chain problems. The study offers valuable insights for organizations aiming to achieve sustainability goals while maintaining economic viability and customer-centric operations.
