• Resumo
• This paper uses multimethodology for evaluating proposals in public procurement by integrating the Complex Holographic Assessment of Paradoxical Problems (CHAP²) with Data Envelopment Analysis (DEA), focusing on Full Dimensional Efficient Faces (FDEFs) and Enhanced Russell Graph Measure (ERGM). Grounded in Systems Thinking, CHAP² structures the decision problem through conceptual mapping, capturing paradoxes, divergences, and contextual specificities before moving to quantitative modeling. DEA then constructs efficiency frontiers supported by reference decision-making units (DMUs) and evaluate proposals, ensuring transparent and strictly positive trade-offs among technical and economic attributes. The methodology was validated with the Brazilian Navy during the structuring phase and applied in a simulated tender using secondary vessel data. Results demonstrate that the approach enhances transparency, avoids distortions from zero-weight solutions, and strengthens compliance with the Most Economically Advantageous Tender (MEAT) principle. The study contributes by showing how Systems Thinking facilitates problem structuring and enables the design of robust multimethodological frameworks for complex procurement environments.
