Abstract The paper describes decision-making models based on a newly introduced notion of personal expected value. Such models exhibit the ambiguity aversion, which is controlled by a subjective parameter with the semantics of “the higher the aversion, the higher the coefficient”. For negative values of this parameter, the models thus manifest a positive attitude to ambiguity. If this parameter equals zero, then the respective model turns into the usual belief function without the aversion to ambiguity. In this case, the personal expected value equals the recently introduced Shenoy's expectation. Finally, the behavior of these models is briefly compared with experimental data.

歧义下的主观期望值

摘要 本文描述了基于新引入的个人期望值概念的决策模型。此类模型表现出歧义厌恶，由主观参数控制，语义为“厌恶程度越高，系数越高”。对于该参数的负值，模型因此表现出对歧义的积极态度。如果这个参数等于 0，那么相应的模型就会变成通常的信念函数，而没有对歧义的厌恶。在这种情况下，个人期望值等于最近引入的 Shenoy 期望值。最后，将这些模型的行为与实验数据进行了简要比较。
