چکیده

همکاری در زنجیره ی تامین به عنوان یک تفاوت در کسب و کار و یک منبع ایجاد مزیت رقابتی شناخته شده است. یکی از پرکاربردترین انواع همکاری در زنجیره ی تامین، قرارداد مدیریت موجودی توسط فروشنده می باشد. در این مقاله یک سیستم مدیریت موجودی توسط فروشنده دو سطحی با یک تامین کننده و چندین فروشنده مورد مطالعه قرار گرفته است. در این سیستم چند محصولی، تامین کننده کالاها را به صورت دوره ای برای فروشندگان ارسال می کند. با توجه به اینکه در واقعیت در مورد میزان بودجه و فضایی که شرکت ها می توانند دردسترس داشته باشند، قطعیتی وجود ندارد، محدودیت های تصادفی فضای انبار و بودجه ی تامین کننده و فروشندگان به مدل افزوده شده است. هدف مدل حداقل کردن کل هزینه های زنجیره ی تامین با تعیین مقادیر بهینه ی سفارش برای هر فروشنده به ازای هر کالا می باشد. در انتها ارایه ی مثال عددی حل شده بوسیله ی نرم افزار GAMS24.1.2 و تحلیل حساسیت روی پارامترهای تامین کننده و فروشندگان روشن ساخت که توجه به پارامترهای تامین کننده برای کاهش هزینه های کل سیستم موثرتر است

عنوان مقاله [English]

A robust optimization approach to multi-objective, multi-product and multi-period green supply chain network design by considering discount in uncertainty conditions

چکیده [English]

Supply chain collaboration has been recognized as a potential business differentiator and a source of creating competitive advantage. One of the most common collaborations in the supply chain is vendor managed inventory. In this paper a vendor managed inventory system at two echelons with one vendor and multi retailers is studied. At this multi products system, goods are send to retailers cyclically. At reality, there is no exactness about available capacity of warehouses space and budget of both partners. Therefore stochastic constraints of warehouse space and budget are added to the model. The goal of the model is to minimize the total cost of the supply chain by optimizing the order quantity of each product for each retailer. At the end a numerical example of the model is solved by GAMS24.1.2 software. The sensitive analysis on the partnerؘs parameters cleared that the parameters of the vendor is more effective to mitigate the total cost of the supply chain.
