APPLICATION OF AHP AND ADDITIVE METHOD IN SUPPLIER SELECTION

With the main aim of selecting the optimal supplier of plastic joinery, in the present study two well-known multiple criteria decision making methods, namely Analytical Hierarchy Process (AHP) methodology and additive method, were applied. Four alternatives, i.e., four suppliers were evaluated according to the suggested criteria: price, delivery time and after-treatment following the installation of joinery. The results obtained by the AHP methodology and additive method were compared, and conclusions on the effect of each criterion weight were adopted.
