ABSTRACT
In our day-to-day, we use so many products, some of which can be substituted by another product and some others are the complement of some other product. In the current business world, it is hard to get more profit working as an individual in the supply chain. Cooperation among the supply chain members plays an effective role in increasing the system’s total profit. But the exchange of incomplete information and conflicting interest among the supply chain members make the supply chain disorganized. The definition of sustainability from the point of view of economics is the specification of a set of actions to be taken by present persons that will not diminish the prospects of future persons to enjoy levels of consumption, wealth, utility, or welfare comparable to those enjoyed by present persons.
