Estudo do impacto da gestão da manutenção na confiabilidade da operação de veículos: estudo de caso de frota da força policiais

Abstract

Automobile patrols face challenges such as mechanical wear and technological obsolescence, compromising their efficiency. This study examines the impact of maintenance management on the reliability of police vehicles, highlighting preventive and strategic approaches to renewing the fleet. Collaboration with production engineers facilitates effective practices that guarantee public safety and optimize emergency response. Maintenance processes, vehicle reliability levels, bottlenecks and fleet management improvements were analyzed. The study, carried out between January and May 2024, used daily summaries from a battalion in Maranhão, detailing data on each vehicle, such as mileage, oil changes and mechanical problems. This information was organized in spreadsheets to identify bottlenecks that affect reliability. The analysis included checking mileage, calculating monthly averages, quantifying problems and recurring patterns. Recommendations were made to optimize management, improve efficiency, reduce downtime and increase reliability. During the period, 15 vehicles covered 297,000 km, with a daily average of 255.2 km. Most faced recurring mechanical problems, generating high costs and reducing availability. Only two vehicles operated without constant failures, while seven were active on less than 50% of the days analyzed.Inadequate management of preventive maintenance and excessive wear and tear have hampered efficiency and public safety, reinforcing the need for maintenance schedules, better allocation of resources and renewal of the old fleet
