In this framework engineering companies are strengthened and one of the sectors responsible for the increase of its revenues is Procurement. It is in this context that the subject of this research is inserted in proposing the construction of a model supporting the management of supply an engineering company based in supplier selection. To measure the scientific contribution, this work took advantage of methodological tools ProKnow-C (Knowledge Development Process-Constructivist) and MCDA-C (Multicriteria Decision Support Methodology - Constructivist). With ProKnow-C was selected a relevant bibliographic references and aligned research topic, highlighting the journals, articles, authors and prominent keywords, and held the systemic analysis of the literature, identifying knowledge gaps and opportunities scientific contribution in six analysis lenses - Approach; Uniqueness; Identification of objectives; Measurement; Integration; and Management. In turn, the MCDA-C was applied in an engineering company, specifically in the Supply area, in order to test and demonstrate the potential scientific contributions of this study. 61 PEAs were raised that led to 68 concepts, which were grouped into three FPVs - Team, Budget and Procurement - which in turn were divided into 7 EPVs. The model identified the performance current situation of the Supply area and generate improvement actions for the descriptors identified as most critical, as perceived by the decision maker. The results obtained at the end of the research proved the scientific contributions of the performance evaluation concepts, as a tool for decision support, especially the use of constructivist approach and the management process
