Moderated Information Sets
In this chapter, the information set theory is extended with a moderator’s information about the elements of the information set. The role of moderator is to provide a second opinion about the validity of the information values comprising the information set. The properties of the proposed moderator information sets (MIS) are also investigated. Many illustrative examples are included to show the usefulness of MIS in the real world decision-making.
