Study on General Situation Assessment Method Based on Search Strategy
Wang Xiaoying · Acta Simulata Systematica Sinica · 2005
A general situation assessment search strategy, based on the representation of situation transfer graph, is proposed, and the process of situation assessment is looked upon that of identification and search of situation path in the graph. In the proposed algorithm, Bayesian path classifier is used to classify target situation that is probably reached, Parzen window algorithm is used to modify the conditional probability density of each situation path, and the search in situation graph is realized via the improved depth-first search algorithm. In the experiment, the method had been successfully applied in the running state assessment system of Hydro-generators of Hydroelectric Simulation System of Jilin Fengman. The performance takes precedence over that of the traditional method.
