From Multicriterial Data Analysis Up to the Exclusive Contract

In the present paper, we propose a heuristic for identifying the key supplier of a company. In order to develop the supplier’s evaluation tool, we use the multicriterial data analysis. The main statistical instrument here is the principal component analysis. Using the data from all realized orders of a chosen company in Slovakia from the year 2017, we identify its key supplier. Hence, this study helps to close the gap between theoretical work on principal component analysis and actual practice. The importance of the present work underlines the fact that the company is planning to sign an exclusive contract with the recommended supplier.
