Abstract :
A method for estimating operating time using existing time meter readings by calculating the duty factors for each unit in the system is described. The duty factor is used with the Reliability Block Diagram database, which gives the configuration for each hull and failure database (i.e., the Logistics Support Center Failure database and the 3-M database) to calculate the failure rates and MTBFs (mean times between failure) for parts, units, and systems. Percentage of time used is tested in a regression analysis. It is shown that there is no statistical relationship between the total number of failures per year and the percentage of time a system is on
