Customized Early Warning System Based on HTN for Home Healthcare Model

We adopted hierarchical task network (HTN) planning in a customized early warning system for home healthcare model. It is necessary to design a customized early warning system for the patients who were in various health states, because regular or irregular report format and alarm delivery systems were diversified according to severity of health state. HTN planning is suitable for use of constraint programming so as to effectively prune the search space during the search for solution. An efficient and scalable information control is presented by use of HTN. The paper also briefly deals with a process strategy for the early warning system.
