چکیده

بررسی کالاهای دارای طول عمر محدود در زنجیره تامین در زنجیره تامین تولید و توزیع مواد غذایی اهمیت فوق العاده ای دارد. یکی از این محصولات روغن زیتون تولیدی شرکت فروشگاه‌های اتکا است که تولید و توزیع آن با توجه به عمر محدود همواره با چالش‌های مختلفی همراه است. لذا در این تحقیق، با توجه به بررسی وضعیت کنونی زنجیره تامین شرکت فروشگاه‌های اتکا در سه سطح تولید کننده، انبارش و توزیع کننده، مدل جدیدی برای تعیین مقدار بهینه توزیع که منجر به کاهش هزینه‌ها در این شرکت شود، ارائه شده است. ابتدا مدل سه سطحی ای را ارایه و تشریح شده و سپس با استفاده از نرم افزار گمز و هم چنین الگوریتم ژنتیک و با استفاده از اطلاعات دریافتی از شرکت فروشگاه‌های مقدار بهینه توزیع روغن زیتون تعیین شده است. که با توجه به نتایجی که از حل مدل بدست آمده است، اجرای مدل برای شرکت فروشگاه‌های اتکا نه تنها مقدار بهینه  توزیع را مشخص کرده بلکه منجر به کاهش هزینه‌ها می‌شود که می‌توان هزینه‌های حاصله از آن را در بخش‌های مختلف دیگری سرمایه گذاری کرد.

چکیده [English]

Studying the Supply chain for products with the limited lifespan is important not only in the supply chain but also in production and distribution of food. One of these products is the Olive oil produced by the ETKA Company, whose production and distribution always have different challenges with regard to their limited life. Therefore, in this study, considering the current status of the supply chain of the supermarket stores in three levels of producer, storage, and distributor, a new model for determining the optimal distribution that leads to lower costs in the company is presented. Firstly, the three-level model was presented and described and then using the GAMS software and also the GA algorithm and by using the information received from the company, the optimum distribution of olive oil was determined. Based on the results obtained from the model’s solution, implementation of the model for the supermarket stores not only determines the optimal distribution but also leads to lower costs, which can be spent on investment in different sectors.
