Supplier selection is one of the preliminary works for the establishment of Green Supply Chain Management. It is a process which incorporates planning, implementing, and controlling the activities of an industry from the conservation of environment point of view. With the advent of Globalization, Green Supply Chain Management has drawn maximum attention whether for the procurement of raw materials or for the delivery of the finished products as it costs about fifty percent of the company's cost and if not managed properly, the competitors get an edge over others. The selection of the best supplier out of the available alternatives has a long-lasting impact on the future of the business because any wrong decision taken in terms of evaluating the criteria and the suppliers would lead to the downfall of the firm. The process of supplier selection is cumbersome and requires strong statistical methods and decision making tools, which have the capabilities to trade-off amongst various cardinal and ordinal preferences. Thus, it is looked upon as a multi criteria decision-making problem, which includes both qualitative (quality, cost, minimum order quantities) and quantitative factors (Discipline, attitude, response, etc.) and hence of strategic importance.
