چکیده

در این مقاله یک مدل برنامه‌ریزی عدد صحیح مختلط چندهدفه، چند محصولی جهت برنامه‌ریزی تولید،توزیع،حمل‌ونقل با در نظر گرفتن شاخص‌های پایداری در شبکه زنجیره تأمین حلقه بسته صنعت غذا ارائه شده است. ابتدا پس از مرور ادبیات موضوع و با استفاده از نظرات خبرگان دانشگاه و صنعت غذا مهم‌ترین شاخص‌های پایداری با ابعاد سه‌گانه اقتصادی،زیست‌محیطی و اجتماعی در این صنعت،استخراج و ساختار روابط شبکه و میزان تأثیرگذاری و تأثیرپذیری هریک از شاخص‌ها از طریق تکنیک دیمتل تعیین شده‌اند سپس این تکنیک با روش فرآیند تحلیل شبکه‌ای به‌منظور تعیین اوزان هر بعد و شاخص‌های آن ترکیب گردیده و درنهایت شاخص‌های دارای اولویت بالاتر انتخاب شده‌اند.در ادامه یک مدل ریاضی عدد صحیح مختلط جهت برنامه‌ریزی تولید،توزیع،حمل‌ونقل زنجیره تأمین پایدار حلقه بسته با ابعاد سه‌گانه فوق‌الذکر ارائه شده است که در آن شاخص‌های حاصل از تکنیک دنپ،هزینه کل از بعد اقتصادی با وزن 1301/0مصرف آب ‌و مصرف ‌انرژی از بعد زیست‌محیطی با اوزان0578/0، 0580/0و فرصت‌های شغلی از بعد اجتماعی با وزن0911/0به‌عنوان توابع هدف مدل‌سازی شده سپس با روش L-P متریک و با استفاده از نرم‌افزار گمز حل‌شده‌اند و مجموعه جواب‌های بهینه پارتویی به دست آمده است در پایان مطالعه موردی درزمینه صنایع لبنی به کمک داده‌های واقعی صورت گرفته است. اجرای مدل منجر به یافتن 8 دسته جواب بهینه پارتویی شده به‌طوری‌که کمترین میزان هزینه در بین جواب‌ها حدود 68 میلیون ریال در ماه، کمترین میزان مصرف آب حدود 660 مترمکعب در ماه و بیشترین میزان فرصت‌های اشتغال حدود 39 هزار نفر ساعت در ماه می‌باشد.

چکیده [English]

This paper presents a multi-purpose, multi-product mixed integer planning model considering the sustainability criteria to plan production, distribution, transportation in the food industry’s closed-loop supply chain. After reviewing the literature on the subject and using the opinions of university and food industry experts determining the most important sustainability indices with the three economic, environmental and social dimensions in the food industry, the relationship structure and effectiveness and impressionability levels of each indices were determined by DEMATEL technique and The technique is combined with a analysis network process to determine the weights of dimensions and their indices. In the second step, a mixed integer mathematical model was presented for planning the production, distribution, transportation of sustainable closed-loop supply chain dimensions with the above three dimensions, in which indicators from the DANP technique. Total cost of economic dimension of weighting 0/0101, for environmental dimension water consumption and energy consumption with weightings of 0/0578, 0/0580 and job opportunities of social dimension for weighting of 0/0911 modeled as goal functions. Then with the L-P metric method was solved by using GAMS and some optimal Pareto solutions were obtained. At the end, a case study was performed on the dairy industry with the help of Real data. Based on the solutions obtained, the lowest cost was found to be about 68 million rial per month, the lowest consumption rate of water was found to be about 660 m3 per month and the highest employment opportunities was found to be 39,000 man hours per month.
