Multistep Decision-Making in Case-Based Planning

During the course of decision-making in case-based planning, users´ experience and knowledge is very significant. This paper discusses how to incorporate them into PLANAUTHOR, a case-based planning system developed by us, before making a decision. Using templates, the authors give a new method, integrating case-based reasoning with decision tree algorithm, to make a multistep decision in case-based planning. The templates in this system were first used to obtain a plan frame in terms of notified situations. The integration helped the users decide whether a step should be carried out at the strategic level and how the step is performed at the tactical level, in turn. The results show that the integration can improve efficiency and quality of planning with templates. Most of all, past cases can make the users more confident about the solutions proposed by the system
