Service domains constitute an application field where AI planning can significantly contribute towards achieving automatic and adaptable compositions. Within the last years, several approaches have addressed the problem of Web Service composition as a planning task. Most of these approaches, however, suffer from one or more of the following main limitations: they restrict the applicability of the domain to a set of predefined procedural templates; cannot efficiently deal with numeric-valued variables, especially when these regard sensing outcomes or operator inputs; and disregard recovery from runtime contingencies due to erroneous service behaviour or exogenous events that interfere with plan execution. To address these issues, we propose to use a domain-independent planning framework, called the RUG planner, which is based on modelling the planning task as a Constraint Satisfaction Problem. This planning system is used to meet the requirements posed by three different service-oriented platforms: a domain consisting of services publicly available on the Web, a Smart Home with intelligent devices, and a framework for Business Process recovery.
