Análise multicritério AHP aplicado à homologação de fornecedores na indústria da construção civil

Abstract

The selection and approval of subcontractors are critical milestones in the development of construction projects within the civil engineering industry. The choice of supplier directly influences the quality, timeline, and cost of the final product. This study proposes the implementation of a decision-support tool based on the Analytic Hierarchy Process (AHP) to enhance this selection process. A literature review was conducted to examine the subcontractor selection and approval practices adopted by major construction firms. The study involved a bibliographic review to identify evaluation criteria, which were subsequently validated by 32 construction professionals in Curitiba, Brazil. The most relevant criteria were prioritized, and their respective weights were determined using the AHP method. As a result, a tool was developed to rank subcontractors based on technical, financial, quality, and relationship criteria. A practical application of the model, through a case study involving subcontractor selection, demonstrated its effectiveness and coherence in enabling more informed and accurate decisions. The model can be integrated into standardized selection and approval processes, promoting more rigorous and transparent practices in the industry.
