Extended Goals for Composing Services

چکیده
The ability to automatically compose Web Services is critical for realising more complex functionalities. Several proposals to use automated planning to deal with the problem of service composition have been recently made. We present an approach, based on modelling the problem as a CSP (Constraint Satisfaction Problem), that accommodates for the use of numeric variables, sensing and incomplete knowledge. We introduce a language for expressing extended goals, equipped with temporal constructs, maintainability properties, and an explicit distinction between sensing and achievement goals, in order to avoid undesirable situations.

However, in order to automatically compose new services, existing services need to be encoded in a machine understandable form. The semantics of a service can be described by annotating it with respect to service ontol...
متن کاملPlanning with Workflows - An Emerging Paradigm for Web Service Composition
In a previous work, we had analyzed the gaps in the prevalent approaches (i.e., Semantic Web Services and WSDLdescribed Web Services) for the problems of modeling, composing, executing, and verifying Web services, and derived challenges for the AI planning community. The challenges were in representation of complex actions, handling of richly typed messages, dynamic object creation and specific...
متن کاملChallenges in Composing and Decomposing Assurances for Self-Adaptive Systems
Self-adaptive software systems adapt to changes in the environment, in the system itself, in their requirements, or in their business objectives. Typically, these systems attempt to maintain system goals at run time and often provide assurance that they will meet their goals under dynamic and uncertain circumstances. While significant research has focused on ways to engineer selfadaptive capabi...

Abstract: In recent decades, high profits of extended warranty have caused that third-party firms consider it as a lucrative after-sales service. However, customers division in terms of risk aversion and effect of offering extended warranty on manufacturers’ basic warranty should be investigated through adjusting such services.
