Industries incur huge costs for maintenance of their assets, be it fixed assets like compressors, etc or mobile assets like trucks, etc. This is because scheduled/preventive maintenance is still prevailing across many sectors. On the other hand, breakdowns/unplanned shutdowns also lead to further production losses, costing manifold compared to the cost of the failed component itself.

The Engineering Analytics team of Capgemini DEMS (Digital Engineering and Manufacturing Services), developed an accelerator, PredictEAP, which computes asset health score and predicts its failure well in advance by computing its RUL (Remaining Useful Life) and as well prescribes relevant advisory to the operators for necessary action to minimize the impact.
PredictEAP is a cloud-based analytics framework for asset health prognostics. The framework enables condition-based asset maintenance and production scheduling. It is developed using reusable components and pluggable modules. This framework is technology agnostic and has the ability to integrate with market leading platforms such as Amazon Web Services and Microsoft Azure.
PredictEAP Reference Architecture
The multi-tier view of PredictEAP framework, shows framework insights, right from data sources layer which constitutes Sensors, Historian, Machines logs or PLM data, or it could be coming from Asset life cycle management or Enterprise asset management systems.
The next layer is OT Data ingestion and integration layer, where custom scripts or self-tools such as Apache SQOOP and Azure data factory are used for data ingestion and data pre-processing where most of the data cleaning is done. The next layer is the cognitive computing engine comprising of prediction models, be it fully data-driven or a hybrid model also involving physics as well as expertise of domain consultants. The top layer shows the business solution suite where use cases are implemented.
PredictEAP Dashboards showing Advisory Statistics
The analytics dashboard shows various views based on diagnostics advisory. The advisory page provides options to select and filter advisories based on site, category, asset type, priority, and date range. The advisory statistics page (shown above) displays a spectrum of graphs to provide details on advisory based statistics, like site-wise advisory details, priority-wise site advisories, and so on. Our framework supports tools like Microsoft PowerBI and Tableau for visualization of live dashboards and interactive reports.
