Proposes a new approach to the dependability modeling of complex repairable systems by combining quantitative identification to critical failures upon listing situations of mission in succession. According to quantitative expression to critical failures, the mission success probability is chosen as a measure of the dependability of complex repairable systems. The approach can provide a numerical solution for mission success probability when both the Mission Time Between Critical Failures (MTBCF) and the Mission Time To Restore Function (MTTRF) is constant. Finally, a detailed application of the approach to dependability modeling during the campaign mobile mission of a ground vehicle is given as an engineering example.
