Equivalent Information for Multiobjective Interactive Procedures
探讨多目标交互方法中不同信息类型（如局部权重、局部权衡、参考点）之间的等价关系，帮助决策者选择自己偏好的提问方式，从而提高回答一致性和方法成功率。
Despite the mathematical properties and algorithmic features of an interactive method, that method’s success usually lies in the kind of information it requires from the decision maker. In some cases, this information constrains the decision maker. If she does not find it easy and comfortable to answer the questions posed by the algorithm, then she will very likely give inconsistent answers, and the method will fail to find her most preferred solution. Therefore, it is of interest to find relations among the different kinds of information (local weights, local trade-offs, reference points, etc.) to allow the decision maker to choose what kind of questions he wants to answer, and to provide him with enough information to give such answers. In this paper, we define equivalent information—that is, different kinds of information—that produces the same solution when used in their corresponding interactive schemes.
