PF Curve

A PF Curve is a graphical representation of the relationship between the probability of failure (PF) and the time to failure (TTF) of a system or component. It is used in maintenance operations and management to predict the likelihood of a system or component failing over a given period of time. The curve is typically constructed by plotting the probability of failure against the time to failure for a given system or component. The curve can be used to identify potential failure points and to plan maintenance activities accordingly. It can also be used to compare different systems or components and to assess the effectiveness of preventive maintenance strategies.
