To deeply understand homogeneous Markov transition probability method, the authors firstly consider a structure with three conditions. The model structure is shown in Fig. 2. The model structure shown in Fig. 2 is called Hidden Markov Model (HMM) with conditions. According to the model structure, homogeneous Markov transition probability, namely, P{objectn+1, Hi, Sj, Ak|Objectn}, is defined as: pTRijk,Hi,Sj,Ak=pTjk,Hi,Sj,Ak|Tik=pTjk|Hi,Sj,Akp{Hi}+pSj(t)|Sj(t-1)+pAk(t)|Ak(t-1) For the convenience of

摘要:
Monitoring process is an important part in a high safety digital main control room of nuclear power plant (NPP), it is the source extracted information and found abnormal information in time. As the human factors events arisen from monitoring process recently take place more and more frequent, the authors propose a reliability Markov model to effectively decrease these abnormal events. The model mainly analyzes next monitoring object probability in terms of current information and plant state. The authors divide digital human-machine interface into two parts that are referred as logical homoge...
