General Forms Based on Conditional Functional Event in M-DUCG

【目的】为克服在基于条件作用事件对所关注的假设事件进行展开时的困难过程。【方法】以命题的形式给出了基于M-DUCG中条件作用事件展开的一般形式,利用事件展开算法对结论进行了严谨的推导和证明。【结果】将所给的一般形式运用于展开事件的过程中,涉及到条件作用事件时,只需找出相应标号,代入所给命题的结论中,并将一般形式应用到实例中,实践结果体现出了直接利用一般形式展开的优越性。【结论】在基于证据确定化简图立即得到所关注假设事件的状态事件展开表达式,由此大大减少了计算量,为使用者提供了方便。

[Purposes]In order to simplify the difficulty of the expansion process that when the hypothetical events of interest are ex panded based on conditional events,especially when the number of parent variables is enormous.[Methods]The general forms based on conditional functional event in M-DUCG with propositional forms,a detailed deviation is given to make the proof.[Findings]The application of the general forms to a real problem,demonstrates the advantages of using it directly.[Conclusions]In the process of determining evidenee-based simplified graphs and expanding events which involves conditional functional event,the only requirement is to find corresp on ding labels and substitute them into the conclusion of given propositions,then the targeted expression of state event expansion of the hypothetical event can be obtained immediately,which greatly reduces the amount of time of calculation and also make it easier for interested researchers to use it.
