Supplier selection and planning model using the analytic hierarchy process

Supplier selection is a multi-criteria decision making problem which includes evaluation of factors. In order to select the best suppliers it is crucial to consider both the qualitative and quantitative factors simultaneously. In the selection process of suppliers, manager also has to consider multi-criteria factors related with decision. Thus the integration of all the multi-criteria analysis and those analysis results by multi-analysis teams has an important meaning in supply chain design. In this paper we proposed a supplier selection analysis model considering both by AHP method and integration method of analysis results. The proposed first analysis model using AHP which is a three-step decision analysis model which converts the qualitative factors of suppliers transferred into the quantitative measure reliability. Then, the integration model integrates the results of multi-analysis and selects the best supplier. Also we developed a computer program for both the AHP model and for integration model.
