Where: AZmp = Effective repair rate of main processor State 11- Power Supply State 11 is the failure of one of the dual power supplies in a channel. The transition from the initial state to the intermediate state is given by: k1,1 = 2 l X•s The transition from the intermediate state to the initial state representing the repair of the initial failure is given by: k11,1 = / The transition from the intermediate state to a spurious trip representing failure of the remaining power supply in the channel is given by: k11, 12 = s Where: 1 = Number of power supplies per channel XS = Safe failure rate for power supply M =ps Effective repair rate of power supply Effects of Common Cause Failures The effects of dual or triple mode failure is modeled directly as a transition from the initial state to the spurious trip state. The common cause failure includes two factors. The first factor (P3) is for the chance of the remaining two channels failing after the first channel fails. Three safe failures or three dangerous detected failures of any channel would cause a spurious trip. The second factor (P2) is for the chance of a second channel failing after the first fails. Two safe undetected failures could cause a spurious trip. Since no clear software model exists, the software contribution to common cause failure is not modeled or included. The common cause failure transition is given by: MPR Associates, Inc.
