In the master's thesis, we discuss the analysis of procurement sources and we upgrade the decision-making process using a multi-criteria decision model. Due to increasing competitiveness and the desire to make purchasing savings, the selected company Ebm-papst started searching for new purchasing sources in the area of Southeast Europe for the aluminum castings product group. With the analysis, we found that the company has only defined the process of evaluating existing suppliers, so we proceeded to upgrade the selection process of a new supplier. In the first step, based on a review of the professional literature, we empirically examine and highlight the most important criteria in selecting a new supplier. These were selected based on the SPM and PPM matrix. For obtaining data, quantitative and qualitative research methods were used. The analysis was performed on the basis of completed questionnaires and assessments performed during a visit to suppliers. An unstructured in-depth interview was also conducted with five experts, purchasers of aluminum castings. Due to the complexity, we divided the decision-making problem into two stages. In the first stage, we defined the exclusion criteria and tested the hypotheses with a t-test. We prepared a decision model using the DEX method and defined four strategies of approach to new suppliers in the inclusion of the latter in the panel of the suppliers, which will have practical implications for the selected company and more. We evaluated twelve suppliers and, based on practical tests, we evaluated the developed model and we also proposed model-related improvements. In conclusion, we made suggestions for improvements for the entire process of selecting new suppliers in the selected company. |
