Özet:
This study focuses on the improvement of supplier evaluation and order allocation decisions for one of the leaders of the white-goods manufacturers in Turkey. A decision support system (DSS) is developed to increase the quality and speed of decision making. In the current purchasing system, the decision maker evaluates the supplier candidates informally and after tough negotiations quota diversification is established. In the proposed system, a tool is developed to evaluate the suppliers with qualitative and quantitative criteria and allocate annual quota so as to optimize a set of purchasing goals.
