We'll cover seven specific types of maintenance, including preventive, planned, condition-based, predictive, reactive, emergency, and corrective maintenance. The 6 different types are: default maintenance, preventive maintenance, corrective maintenance, condition-based maintenance, predictive maintenance and reactive maintenance. Workplace maintenance refers to the process of ensuring that a certain piece of equipment, machine, item or facility is in good condition and working before and after use. It comes in different types, namely preventive maintenance, corrective maintenance, state-based maintenance, planned maintenance, predictive maintenance, risk-based maintenance, reliability-focused maintenance, and proactive maintenance. Risk-based maintenance (RBM) consists of using a risk assessment methodology to assign scarce maintenance resources to the assets that pose the greatest risk in the event of a failure (remembering that risk = probability x consequence).
Until recently, when talking about predictive maintenance (PDM), this basically referred to a synonym for condition-based maintenance. However, with the advent of artificial intelligence, the much lower costs of equipment sensors (IIoT) and machine learning, the difference between predictive maintenance (PDM) and condition-based maintenance (CBM) is evident, at least in my opinion.
