Preventivepredictive

Preventivepredictive is a hybrid maintenance concept that integrates traditional time-based preventive maintenance with condition-based predictive maintenance to optimize asset reliability and maintenance costs.

The approach uses sensors and data collected from equipment to monitor health indicators. It combines prescribed service intervals with model-based predictions of failure probability or remaining useful life, enabling maintenance actions to be scheduled when warranted rather than strictly by time or by fault detection alone. Implementation typically involves data acquisition from industrial Internet of Things devices, data preprocessing, analytics or machine learning models, and integration with a computerized maintenance management system to update work orders and inventory plans.

Benefits include reduced unplanned downtime, longer equipment life, and more efficient spare parts usage. By aligning preventive tasks with predictive insights, organizations can adjust maintenance windows and optimize resource allocation while maintaining required reliability levels. The approach can support better planning of maintenance budgets and inventory, as well as clearer prioritization of interventions across a portfolio of assets.

Challenges include ensuring data quality and interoperability, selecting appropriate models, and justifying the upfront analytics investment. Organizations must manage change, address cybersecurity risks, and maintain governance over data standards and decision rules. Success often depends on clear ownership, skilled personnel, and an iterative process of model validation and process refinement.
