Improvements to the maintenance system for radio-electronic equipment in companies in northern Holguín

Abstract

This paper focused on the analysis of the maintenance management of radio electronic equipment in companies in the northern Holguín region (ETNH). Changes were proposed that contributed to improved performance and outcomes. The Planned Preventive Maintenance system was applied, with acceptable results, but with significant room for improvement, which led to changes in the system. Several methods were used for all technological equipment to facilitate the acquisition of information that allowed for decision-making, but focused primarily on the systems and elements with the greatest impact on the occurrence of SWR (Standing Wave Ratio) failures, such as the antenna, low-pass filter, switching card, high-voltage source, and coaxial cable. This failure was the most significant, and allowed determining technical availability based on the mean time between failures, mean time to repair, maintenance and repair costs, and the actual operating conditions of the equipment. The main tools used are Criticality Analysis and Pareto. With the information available through the use of these tools, proposals for improvements were made based on the results obtained
