Avoiding Pitfalls in Case-based Planning

Case-based planning is considered as a valuable tool for improving efficiency in planning by reuse and modification of existing plans. In this paper, the results of an empirical study are discussed in which several factors influencing case-based planning are investigated. The results demonstrate relative efficiency gains or losses caused by different refitting strategies, different types of plans or typical properties of the application domain and identify possible pitfalls for case-based planning.
