    • The present invention relates to a method for operating a decision support system (DSS) with a Bayesian Network (BN), the Bayesian Network having conditional probabilities (CP) assigned to each node. There is applied a confidence measure (CM) during use of the decision support system (DSS) on a probability of interest (POI) in a node of interest (NOI), wherein the confidence measure (CM) is a measure for the change of the probability of interest (POI) with respect to a change in one conditional probability (CP_i=x). The invention can quite significantly increase the confidence in the proposed decision of the DSS. The DSS can, indirectly or indirectly, utilise one or more confidence measures (CM) as an input to the proposed decisions or tests to be made by the user; e.g., a clinician considering whether or not to make a certain diagnostic test can be informed of the confidence measure (CM) associated with the diagnostic value of the test as calculated from the BN.
    • 本发明涉及一种用贝叶斯网络(BN)操作决策支持系统(DSS)的方法,所述贝叶斯网络具有分配给每个节点的条件概率(CP)。 在使用感兴趣节点(NOI)中的感兴趣概率(POI)的决策支持系统(DSS)时使用置信度量度(CM),其中置信度量度(CM)是用于改变 关于一个条件概率(CP_i = x)的变化的兴趣概率(POI)。 本发明可以显着增加DSS提出的决定的信心。 DSS可以间接或间接地利用一个或多个置信度量度(CM)作为由用户作出的所提出的决定或测试的输入; 例如,可以考虑是否进行某种诊断测试的临床医生可以通知与从BN计算的测试的诊断值相关联的置信度量度(CM)。
