Decision problem structuring: generating options

An integrative framework of methods for generating options for subsequent evaluation in a formal decision analysis is proposed. The overall process of decision problem structuring is briefly discussed. An associative network model of the way knowledge is represented cognitively is presented. Five categories of option-generating procedures are identified, including attribute-based, state-based, composite, option-based, and creativity techniques. The different option-generating procedures are seen as different strategies for traversing the cognitive network to search for and/or create options. The approaches differ by the type of cognitive unit (decision problem attribute, state, or option) to be brought into short-term memory to stimulate further search. Criteria for evaluating the sufficiency of the set of generated options are also presented. A discussion of future research directions is included
