Overview

The purpose of this DAG is to streamline the retraining process of machine learning models used for predictive maintenance in the Defense and Aerospace industry. By automating the integration of new data, the DAG enhances model accuracy and responsiveness to changing operational conditions. The data sources include sensor data from aircraft systems, maintenance logs, and historical failure data. The ingestion pipeline captures these inputs, ensuring they are pre-processed and formatted for analy

The purpose of this DAG is to streamline the retraining process of machine learning models used for predictive maintenance in the Defense and Aerospace industry. By automating the integration of new data, the DAG enhances model accuracy and responsiveness to changing operational conditions. The data sources include sensor data from aircraft systems, maintenance logs, and historical failure data. The ingestion pipeline captures these inputs, ensuring they are pre-processed and formatted for analysis. Processing steps involve evaluating the current model's performance, applying retraining algorithms, and validating the updated models against predefined KPIs. Quality controls are implemented to monitor retraining time and improvements in accuracy. The outputs consist of updated predictive models, performance reports, and alerts for any anomalies detected during the retraining process. Key performance indicators (KPIs) include retraining duration and accuracy enhancement metrics. This automated approach not only reduces manual intervention but also increases the reliability of predictive maintenance forecasts, ultimately leading to reduced downtime and enhanced operational efficiency. The business value lies in the ability to proactively address maintenance needs, thereby minimizing costs associated with unexpected failures and extending the lifecycle of critical assets.
