Desenvolvimento de um sistema computarizado para optimização da gestão de manutenção eléctrica na planta de processamento da Montepuez Ruby Mining

Abstract

This Final Year Project aimed to develop a computerized system to optimize electrical maintenance management at the Montepuez Ruby Mining (MRM) Processing Plant, located in Cabo Delgado, Mozambique. The project responded to practical challenges such as decentralized manual records, lack of technical performance indicators, limited traceability of interventions, and poor interdepartmental integration. The research adopted an applied approach, combining qualitative and quantitative methods, including literature review, field data collection, technical form analysis, and interviews. The diagnosis revealed a predominance of corrective maintenance actions, absence of KPIs such as MTTR and MTBF, and difficulties in accessing historical data. Based on this assessment, a customized Computerized Maintenance Management System (CMMS) was developed using PHP, HTML, CSS, JavaScript, and MySQL. The system allows for asset registration, digital work order management, automated KPI calculation, and report generation. After field validation, the solution demonstrated significant improvements in information organization, preventive planning, and response time reduction. The developed system aligns with Industry 4.0 principles, offering potential for future integration with IoT sensors and SCADA systems. The proposed solution proved to be technically feasible, functional, and effective in improving the reliability, efficiency, and operational continuity of electrical maintenance at MRM.
