A Parametric Representation of Additive Value Functions
提出一种新参数来度量属性间的确定性偏好权衡，并给出价值函数可加性的充要条件，为评估和转换非加性表示为加性形式提供方法。
This paper introduces a new parameter for measuring deterministic preference tradeoffs between pairs of attributes. In terms of this parameter, necessary and sufficient conditions for a value function to be additive are established. When additivity conditions are satisfied, a set of these parameters is shown to characterize the value function uniquely up to a set of scaling constants. Implications for assessment, for transforming a nonadditive representation into an additive one, and for multiattribute utility functions are presented.
