Integrated purchase management: a process model for supplier selection based on fuzzy logic

The search for competitive advantage through the interconnection of organizational processes allows the reduction of time and expenses for companies. 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. 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.
