A MULTI-OBJECTIVE APPROACH FOR OPTIMUM QUOTA ALLOCATION TO SUPPLIERS IN SUPPLY CHAIN

In all industrial firms where a large number of parts and components are supplied by different suppliers to the raw materiel stores. So it is necessary to keep a track of their performances and supplier ratings individually. The shortages of many basic raw materials and unfriendly attitudes on the part of suppliers can seriously jeopardize production units. So supplier evaluation comes a necessary task. The supplier selection in the supply chain is a multi-criteria problem for this a problem is formulated. The formulated problem is including three primary objectives such as minimizing the net purchase cost, minimizing the net transportation cost and minimizing the net late deliveries subject to realistic constraints regarding buyer’s demand, vendor’s capacity, budget allocation to individual vendor, Vendor’s quality of the items, vendor’s quota flexibility, purchase value of items etc. This paper consists of allocating the quota to suppliers from a set of pre-selected candidates. In this paper the Lexicographic Method is used and solved above three objectives on the priority basis. A real life example is also presented and solved by the MATLAB and results are shown in the paper.
