A DYNAMIC MODEL FOR STRUCTURING DECISION PROBLEMS

This paper develops a new model of decision problem structuring which synthesises a number of models and approaches cited in the decision making literature in general and the multi-criteria literature in particular. The model advocates a dynamic interaction between criteria and alternatives as a decision maker understands his preferences and expands the set of alternatives. This model endeavours to bridge the gap between prescriptive and descriptive approaches. It is prescriptive in its orientation, recommending an approach based on earlier prescriptive work. The model, however, is also validated empirically, based on the descriptive decision making literature and reported case studies of actual decision making.
