SBN(Series Bayesian Network) model and constructing algorithm of BN are introduced, and advantages and disadvantages of constructing SBN with MEBN(multi-entity Bayesian networks) are pointed out. Aiming at the demands of constructing SBN, expression of Markov MFrag(MEBN Fragment) within MEBN system is clarified, and probability mapping pseudo MFrags are added, then SBN constructing algorithm based on Markov extended MEBN system is studied and the constructing procedures are illuminated by an example. © (2014) Trans Tech Publications, Switzerland.

Aiming at the optimal decision problem of multi factors, model is proposed of establishing BN with cause-and-effect relationships, constructing evaluation function with multi factors by decision objectives, finally comparing and selecting the optimal solution of evaluation function from all possible decisions. The model inherits the ability of numerical reasoning and can analyze multi factors. Example illuminates procedures of the model in the paper. © (2014) Trans Tech Publications, Switzerland.
