Sometimes, the operators can not judge next possible monitoring object which would lead to monitoring delay or transfer error in the monitoring digital human-computer interface parameter information process in nuclear power plant. Aiming at the situation, the forecasting path plan method including forecasting path model, forecasting path plan algorithm and the calculation method of transfer path success probability and which is based on Markov process was proposed. Then the monitoring transfer behavior of the operators when SGTR(Stream Generator Tube Rupture) occurred abruption accidents is an...
