Goal-Directed Decision Structuring Systems.
Abstract
The report summarizes the development and evaluation of computerized decision structuring systems based on a new representational structure which offers several advantages over the traditional decision-tree representation. The design and operating characteristics of GODDESS (A Goal-Directed Decision Structuring System) and several environment simulators used for evaluating decision aiding tools are briefly outlined. The main body of the report focuses on an experimental evaluation of the effectiveness of two structuring procedures: decision-tree elicitation and goal-directed structuring. The goal-directed procedure appeared superior in encouraging subjects to generate novel (non-habitual) sets of effective options. The tree-elicitation procedure, on the other hand, permitted subjects to articulate more valid judgments and assessments, which in turn facilitated a more accurate recognition of the best action among the options given. The combined use of goal-directed procedures for structuring problems and tree-elicitation for optimization promises to utilize the strengths of both methods. (Author)
