Meer weergeven To calculate the failure rate, divide the number of failures by the total number of hours, such as 4/3,647 = 0.0011 failures per hour. In this example, the failure rate per hour is so small that it is almost insignificant. Meer weergeven For example, if two components are arranged in parallel, each with reliability R 1 = R 2 = 0.9, that is, F 1 = F 2= 0.1, the resultant probability of failure is F = 0.1 0.1 = 0.01. The resultant reliability is R = 1 0.01 = 0.99. Meer weergeven Failure rate can be defined as the anticipated number of times that an item fails in a specified period of time.
