appropriate alerts is equally important. PdM systems use
alerts as feedback systems for effective communication
between machines and maintenance teams.
A PdM system has to be capable of detecting and
averting false alerts, generating structured alerts from
specific data points. Accurate alerts that pinpoint loca-
tion or root sources of errors are preferable to generic
alerts. Creating a database for frequent alerts and error
sources forms a basis for companies to develop a func-
tional failure mode and root cause analysis model.
5. Dealing with security issues. Predictivemaintenance ties industrial assets to various cloud computing platforms, enabled by IoT connectivity. Theseplatforms are necessary for improving real-time dataanalysis and storage of equipment performance metrics.
Once plant equipment is connected to these plat-
forms, maintenance moves beyond physical protection,
bringing on board cybersecurity strategies toward man-
agement of industrial assets.
Priority should be given to safety ofIoT and cloud computing platforms adopted for PdM systems. There are severalinstances of attacks and security breacheson critical infrastructure facilities acrossthe world. There have been reports of severe cyberattacks that have predominantly targeted the Industrial Io T technology.It is important that a PdM system incorporates robust security features againstpossible internal and external attacks.
6. Starting with a pilot project. Before you switch to a predictivemaintenance model, it is important tolay down a strategic implementationplan. Implementation planning identi-fies critical plant assets and maps outpossible implementation bottlenecksthat may arise from adopting a predictive maintenance system.
Transitioning to a PdM system willtake less time if a pilot project is implemented in advance. The pilot projectcan be used as a tool to train staff, testsystem security, and optimize predictivealgorithms.
Many industries are shifting fromreactive maintenance strategies to predictive maintenance. This has been hastened by development of Io T technology,IoT-enabled CMMS solutions, and thefact that the cost of implementation isconstantly dropping down.
It takes time for PdM strategy to befully implemented. Challenges associated with implementation can be significantly reduced by performing prior, in-depth analysis of plant requirements,proper financial and material planning,and sufficient training of maintenanceteams.
