The The search for competitive advantage through the interconnection of organizational processes allows companies to reduce their time and expenses. Therefore, this study had as main objective to propose strategies that allow to find good practices for these actions, whose main objective was to present a model for the selection process of suppliers based on fuzzy logic to improve activities. In this context, integrated purchasing management, supplier selection, fuzzy logic, its pertinence variables and the use of rules established to meet the procurement procedures of a foundation to support Research, Extension and R&D. Finally, the result is a final assessment of suppliers, using the fuzzy inference method developed in the Matlab® software, in the Fuzzy Logic Toolbox environment, in the Mamdani model, taking into account the social and economic criteria for a possible purchase of a very relevant electronic product in the institution, allowing this tool to become practical and applicable to the needs of the sector. After data obtained, it was concluded that the model proved to be very efficient, presenting a minimum difference from one supplier to the other, where the first place obtained a score of 2.06 more in relation to the selected room, seen as the longest distance in compared to the other classifieds, and it is important to continue the relationship with them in future acquisitions, one must also adopt the use of tools to recover those that did not show good results, in addition to the development of new suppliers.

Today's highly competitive environment is forcing manufacturing organizations to establish effective long-term collaboration with efficient organizations. As a result, an effective supplier selection process is very important to the success of any manufacturing organization for cooperation and is essential for companies to get competitive advantage. The purpose of this dissertation is to develop a model that support the decision making on the parts suppliers selection, through the Fuzzy Analysis Hierarchical Process (FAHP), in a supply chain. In order to carry out the suppliers selection process, as data input was used the experts team of Procurement, Quality and Process Engineering areas. From this model, a tool was developed that provided the supplier selection automatic result. The main results were achieved: increasing knowledge, applying the FAHP, defining and presenting the priority and the weights of the criteria for decision making of suppliers selection. It was concluded that the presented model is reliable and simple execution, however, it depends on the expertise and the technical knowledge of the participants on the subject in question. The study presented has its importance for the industry as well as the process presenting relevant results.
