The Recurrence Analysis platform analyzes event times like the other Reliability and Survival platforms, but the events can recur several times for each unit. Typically, these events occur when a unit breaks down, is repaired, and then put back into service after the repair.
The units are followed until they are ultimately taken out of service. Similarly, recurrence analysis can be used to analyze data from continuing treatments of a long-term disease, such as the recurrence of tumors in patients receiving treatment for bladder cancer. The goal of the analysis is to obtain the MCF, the mean cumulative function, which shows the total cost per unit as a function of time. Cost can be just the number of repairs, or it can be the actual cost of repair.
