Avaliação da eficiência das unidades periciais da Polícia Técnico-Científica de Goiás: uma aplicação da análise envoltória de dados

Abstract

The growing demand for forensic investigations forces the Technical-Scientific Police of Goiás (PTC-GO) to constantly improve its work methods and its organizational structure. In this context, it is essential to use good techniques to assess the efficiency of forensic units in order to support decision-makers in structuring the public service provided by PTC-GO in order to meet public policies and the demands of the population. One good tool is Data Envelopment Analysis (DEA), which aims to measure and compare the efficiency of decision-making units according to their specific characteristics. Although it is a widely used technique in several areas, there are not many studies in which it has been applied in forensic field. In this context, this study used the DEA technique to measure the efficiency of the forensic units of the Goiás Technical-Scientific Police. To this end, the number of requests received and the number of experts in each unit per 100,000 inhabitants were considered as input variables, as well as the number of reports produced per 100,000 inhabitants, the ratio of reports to requests and the average time to produce the forensic report. The data were collected from the criminalistics information system – ODIN and the results allowed the construction of an overview of the efficiency levels of the PTC-GO units. From the calculation of targets, it was possible to identify possible bottlenecks and formulate suggestions for the units to reach standard efficiency.
