This paper presents a reliability assessment method for the system with multiple degradation parameters based on SVDD and SVR. The method transforms different performance parameters of the system to a distance measure by SVDD, uses SVR to analyze and predict the distribution parameters of SVDD distance, then create the overall system performance degradation assessment model. Through vehicle tracking experiment, collecting different degradation parameters of the diesel engine, a reliability curve stands for the whole system degradation is achieved. Compared to traditional reliability assessment method, the new method combines the various parameters so that more effectively describes the diesel engine performance degradation, and is more instructive for the maintenance of the vehicle.
