Publisher's Synopsis
When a Decision Maker is asked to provide his or her preferences, the response represents a snapshot in time. While their preference structure elicited at any given moment represents their revealed preferences at that point in time, it may change over time. These changing preferences over time represent ambiguity in the decision maker's preferences. Other sources of ambiguity may result from the presence of groups in the decision making process. One weakness of many decision analysis techniques today is the inability to incorporate this possible ambiguity into the basic decision model.
