Özet:

Selection of an optimal supplier along the supply chain is strategically important for those companies that strive to match supply with demand. Multicriteria nature of the supplier selection problem enables the modelling of the problem by multicriteria decision-making methods. By taking into consideration the interaction between alternative suppliers and the criteria that effect the selection, this study provides background information about multicriteria decision making methods that support companies in decision-making processes. WASPAS (Weighted Aggregated Sum Product Assessment) method is a relatively new and efficient multicriteria decision making method that integrates the basic multicriteria decision making methods of the Weighted Sum and Weighted Product models. This study introduces the theory of WASPAS, the solution of a supplier selection problem with this method and evaluates the comparative results.
