It is difficult for operators in main control room (MCR) of nuclear power plant (NPP) to determine the next possible monitoring object when they are monitoring digital human-machine interface (DHMI) parameter information process, so monitoring delay or transfer error would occurs. According to this situation, a forecasting path programming method (FPPM) in monitoring process was proposed based on human factor reliability. Firstly, forecasting path model in monitoring process is proposed; then a FPPM which covers path tree algorithm building based on information filtration and searching path al...
