Painel de apoio à decisão para priorização das ações da gestão da manutenção corretiva

Abstract

The Brazilian electrical system is formed by inumerous interconnections between transmission and distribution lines and various equipments. In order to keep the entire system working in order, it is required a great amount of work from all the agents involved in its management, especially those focused on maintenance tasks. One way of evaluating the efficiency of the services performed is through the quality and consumer satisfaction indicators, which have specific values that must be followed in all regions of the country and their non-compliance generate penalties for the distributors. In order to characterize an efficient way of prioritizing maintenance actions, an analysis of the historical basis of defects of a local energy distributor was carried out, considering the records made from 2016 to 2019, using some quality tools. Focusing efforts on the defects that have the greatest impact, those with high criticality, it was observed that almost 50% of the corrected defects were executed after the deadline and that most defects are concentrated in a few classifications. At the end, it was suggested to cross the prioritization indicators defined in the study with the base of defects registration to create a prioritization dashboard of corrective maintenance actions, which eneables the efficiency of work groups and gives support to reduce the impacts of feeder failures due to system and equipment defects.
