Main Article Content
Abstract
Predictive maintenance is a critical aspect of ensuring the reliability and efficiency of mechanical systems in various industries. Machine learning (ML) techniques have emerged as powerful tools for predictive maintenance, enabling early detection of equipment failures and facilitating timely interventions to prevent costly downtime and repairs. This paper provides an overview of machine learning applications for predictive maintenance in mechanical systems, presenting case studies, algorithms, and performance evaluation metrics. We discuss the significance of predictive maintenance in enhancing operational efficiency, reducing maintenance costs, and minimizing unplanned downtime. Furthermore, we review various machine learning algorithms commonly employed for predictive maintenance, including supervised and unsupervised learning techniques, deep learning models, and ensemble methods. Additionally, we delve into real-world case studies that highlight the successful implementation of machine learning for predictive maintenance across different industries, such as manufacturing, automotive, aerospace, and energy. Finally, we discuss performance evaluation metrics and methodologies used to assess the effectiveness and reliability of predictive maintenance models, considering factors such as accuracy, precision, recall, and F1-score. Through this comprehensive exploration, this paper aims to provide insights into the practical application of machine learning for predictive maintenance and its potential impact on optimizing the performance and longevity of mechanical systems.
