For any organization to remain competitive, it has to work closely with its supply chain partners i.e. suppliers. Thus, now-a-days supplier plays an important role in an organization for timely manufacturing finished good products which is directly shipped to the markets. Hence, the selection of suppliers becomes an important aspect of any business organization. In any supplier selection process, generally six main decision processes takes place viz: (1) make or buy, (2) supplier selection, (3) contract negotiation, (4) design collaboration, (5) procurement, and (6) sourcing analysis. Of these six decision process, supplier selection is one of the most vital and crucial decision which not only responsible of supplying the parts but also responsible in keeping the organization in a competitive mode. Selection of suppliers becomes more important when an organization has to select the supplier for more than one period and when the supplier’s capacity, their quality level, lead time, and various cost parameters also vary.
