In particular, a solution has been developed and evaluated in the context of an automated home care system. Design/methodology/approach – The work has built on an existing policy-based management system called Advanced Component Control Enhancing Network Technologies (ACCENT). This includes automated management of home care using two forms of rules: higher-level (user) goals and lower-level (system) policies.
