Time for smarter PMs: How intelligent technologies are improving preventive maintenance routines
When budgets are tight, advanced maintenance strategies are reserved for the most critical assets. Predictive maintenance (PdM) and prescriptive maintenance (RxM) fall into this category, with timely intervention triggered by asset condition or performance anomalies.
The other end of the spectrum is the run-to-failure (RTF) approach, which may be perfectly acceptable for non-crucial assets that have reasonable downtime and repair or replacement costs. In between is the widely used practice of preventive maintenance (PM).
