【Abstract】 The state of the system is generally affected by many random factors.The state prediction model based on dynamic bayesian network can more accurately describe the relationship between the system state and the influencing factors.According to this model,the span of the reasoning is proposed to reduce the amount of data in the reasoning process.Meanwhile the multi-step state prediction algorithm is achieved by extending time-slice.更多还原
