چکیده مقاله :
امروزه رقابت بر تمامی فرآیند ها تولید و عرضه محصولات تاثیر گذار است به طوریکه تقریبا اکثر تولید کننده ها و تامین کنندگان مواد اگر به فکر افزایش کیفیت و کاهش قیمت نباشند نمی توانند در بازار سهمی برای خود داشته باشند از این رو دراین مقاله تاثیر رقابت تامین کنندگان مواد اولیه بر هزینه تامین و تدارک مواد برای سازندگان در یک زنجیره تامین چند محصولی حلقه بسته سبز مورد بررسی قرار گرفته است در ابتدا مدل سازی رقابتی در فرآیند تامین مواد بین تامین کنندگان مواد اولیه در گروه های مختلف انجام می پذیرد و از طریق تخمین تقاضا برای هر کدام از محصولات زنجیره و قرار دادن پارامتر های مقدار تقاضای هر محصول و میزان جریان برگشتی در مدل رقابتی با استفاده از اصول تئوری بازی ها به یافتن نقطه تعادل رقابت در میان هر گروه از تامین کنندگان زنجیره می پردازیم در ادامه نیز با حل مدل میزان تغییرات هزینه های تامین و تدارکات کالا برای سازندگان محصولات و تامین کنندگان مواد اولیه زنجیره در دو حالت وجود رقابت و عدم وجود آن با هم مقایسه و تصمیم گیری انجام می شود
Nowaday, competition affects all processes of production and supply of products, so that most manufacturers and suppliers of materials can not have a market share if they do not think about increasing quality and reducing prices, so in this article the effect of competition of raw material suppliers on supply and procurement costs Materials for manufacturers in a multi-product supply chain Green closed loop is examined. First, competitive modeling in the supply process between raw material suppliers in different groups is done by estimating the demand for each of the chain products and setting the demand quantity parameters of each product. And the rate of return flow in the competitive model using the principles of game theory to find the equilibrium point of competition among each group of chain suppliers. Then by solving the model of changes in the cost of supply and goods for manufacturers and suppliers of chain raw materials in two cases The existence of competition and its absence are compared and decisions are made
