本文提出了一个合理化的选择功能,违反了“无关选项的独立性”公理的概念。一个线性排序的集合被称为提供了一个合理化的选择功能的多个理由,如果选择从任何选择集可以合理化的顺序之一。我们刻画了一个紧上界的最小数量的排序,需要合理化任意选择功能,并计算了几个特定的选择程序的最小数量。
The paper presents a notion of rationalizing choice functions that violate the “Independence of Irrelevant Alternatives” axiom. A collection of linear orderings is said to provide a rationalization by multiple rationales for a choice function if the choice from any choice set can be rationalized by one of the orderings. We characterize a tight upper bound on the minimal number of orderings that is required to rationalize arbitrary choice functions, and calculate the minimal number for several specific choice procedures.
