Análise de decisão multicritério: modelo para identificação da viabilidade operacional das unidades de criminalística da Polícia Federal no Brasil

Abstract

Public security is an area of increasing importance in Brazil. Society requires that the public resources applied be managed more efficiently and effectively. Criminalistics is an integral and vital part of the Brazilian public security system and requires new management tools that allow the better allocation of human resources, equipment, and facilities. Faced with a challenging scenario with budgetary constraints in several areas in public administration, the search for innovative approaches should be a constant for the managers of federal forensic sector. The main objective of the research was to develop a multicriteria decision model to evaluate the operational viability of the forensic units of the Federal Police. The framework used produced a multicriteria model to support the decision that used the Best-Worst Method (BWM) to obtain the values of the scale constants of the criteria used, while the ordering of the forensic units was performed by applying the R-TOPSIS method, which uses a new approach to avoid the ranking reversal problem. The proposed hybrid model allowed the ordering of 23 forensic units of the Federal Police existing in the cities of the interior of Brazil. Among the last positions in the ranking, it was possible to recommend the closure of three units and agglutination of two others. The sensitivity analysis performed imposed variations of 10% and 20% in the original values of the scale constants and did not show abrupt variations in the original positions, confirming the robustness of the proposed solution. It is concluded that the model allowed an optimization of resources in the forensic units without compromising the quality of the services provided to society.
