MCDA to improve resources distribution on criminal investigations at Brazilian Federal Police: sorting crime reports in importance and urgency categories
This study presents an MCDA model to deal with crime reports that arrives at the many units of Brazilian Federal Police, using FlowSort methods (crispy, interval and fuzzy). The model aggregates several criteria in two dimensions, one of importance and another of urgency. The importance dimension takes into account seven criteria, like minimum and maximum Amount of Imprisonment penalty, Complexity of Crime, Value of Economic Injury, Hierarchy of Legal Goods and Days After the Facts. In the other side, to characterize the urgency dimension were utilized five criteria, like the Moment of Offense Commitment, Situation of Crime Product, Situation of Crime Evidences, Suspect Behavior and Punitive Prescription. The FlowSort method is then applied to assist in the distribution of crime reports into ordered categories of importance and in another ordered categories of urgency. Both dimensions are considered simultaneously to analyze criminal reports. As a case study, fifteen real criminal reports were chosen and submitted to the model, approved by most consulted experts (89.1% for importance and 83.2% for urgency approval rates). Extending the research and in order to improve the analysis of each Criminal Report when there is a higher level of uncertainty, two other models for importance sorting were created using Interval FlowSort and Fuzzy FlowSort methods. Applying these models, it was possible to observe more differences between the actions, exploring the imprecision and the uncertainty, preserving the decision maker’s subjective information, that was not possible using the traditional FlowSort method. Wherefore, the model supports appropriate use of public resources, aligned with the objective of the Brazilian Federal Police and required from National Constitutional Law, by highlighting more important and urgent investigations. The introduction and adoption of these techniques on the organization are gradually occurring. Moreover, because the number of investigations, policemen and police units, the wide dissemination of MCDA methods also depends on computational resources availability. Hence, the developing of specifics applications are required to aggregate the necessary information and to report the decision makerīs recommendations.
