Proposta de aprimoramento do processo de avaliação e seleção de fornecedores: uma aplicação ao caso do Instituto Federal do Tocantins

Abstract

The problem of selection of suppliers has been addressed with greater relevance and importance for the organizations, since a proper choice and selection of suppliers can bring significant economic results. The need for public and private institutions to reduce costs, to get better quality products and services, looking to improve their competitiveness or even its stability in the market, is causing the supplier selection issue a strategic role in organizations. The current selection models employed by the vast majority of organizations seek to minimize costs, basically leaving aside other important criteria for the choice of suppliers. The present work proposes the assessment of the current model of selection of suppliers within the Federal Institute of Tocantins (IFTO) as well as the creation of two multicriteria decision support models. The research has a qualitative approach in problem formulation and identification of relevant and quantitative criteria for the construction of the multi-criteria models and analysis of results. The two proposed models to support decision have been built using the multi-criteria methods AHP and VIKOR. For the study applied, six vendors were evaluated in relation to quality, cost, delivery criteria and geographic location. The decision models were created from analysis of the evaluations of interviews with four experts in the purchase sector of the IFTO campus Araguaína. With the results of the two proposed models, a comparison was made between them and also in relation to vendor selection model currently practiced in the IFTO. After comparisons of the models, a sensitivity analysis was conducted, where it was noted that the VIKOR model showed up as the most appropriate and suitable for the selection of suppliers within the IFTO.
