Modeling the Impact of Raw Materials Suppliers Competition on Procurement Costs in the Green Closed Loop Supply Chain

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...
