Abstract:

This project was aimed at developing agent-based technology for dynamic plan management, i.e., for automatically monitoring, extending, and updating complex plans for a human user in a changing environment in which the set of goals to be achieved evolves over time. The project succeeded in achieving its objectives, and obtained both theoretical and practical results. In particular, representations and algorithms were developed for four key plan management tasks i deliberation, i.e., determining whether or not to adopt a new potential goal by assessing its cost in context ii plan merging, i.e., integrating plans for new goals into a set of existing commitments, while minimizing the disruption to those prior commitments iii contingency selection, i.e., making effective decisions about which contingency events to plan for in advance, and iii selective execution monitoring, i.e., determining which environmental features to attend to while a plan is being executed. Additionally, we designed and implemented a prototype plan management agent PMA, which builds on these and other plan management algorithms, and assists a user in managing a complex set of plans.
