摘要: Abstract A persistent problem in machine planning is that of repairing plans fail. One approach to this has been shown be quite powerful based on the idea detailed descriptions causes a failure can used decide between different repairs applied. This paper presents an repair which plan failures are described terms causal explanations why they occurred. These domain-level access abstract strategies, then make specific changes faulty plans. The demonstrated using examples from CHEF, case-based planner creates and debugs domain Szechwan cooking. While discussed here examined actual failures, technique also discovered prior their running.
