Abstract：To assess reliability of the diesel engine monitoring system，reliability assessment method for diesel engine monitoring system based on Markov process was proposed. The system's function structure was extracted，and system reliability model was established by taking Markov process to describe system state. Component failure rate parameter was collected by different ways. The influence of component failure rate and repair rate changes on system reliability and availability was analyzed with Matlab numerical evaluation，then component that influenced system reliability much was obtained.  The results show that ratio of failure rate to repair rate impacts on system availability is drawn.
