Description

Service-Oriented Computing (SOC) has been used in business environments in order to integrate heterogeneous systems. The dynamic nature of these environments causes \ changes in the application requirements. As a result, service composition must be flexible, dynamic and adaptive, which motivate the need to ensure the service composition behavior \ at runtime. The development of adaptive service compositions is still an opportunity due to the complexity of dealing with adaptation issues, for example, how to provide runtime verification \ and automatic adaptation. Formal description techniques can be used to detect runtime undesirable behaviors that help in adaptation process. However, formal techniques have been \ used only at design-time. In this paper, we propose an adaptive service composition approach based on the lightweight use of formal methods. The aim is detecting undesirable behaviors in \ the execution trace. Once an undesirable behavior is detected during the execution of a service composition, our approach triggers an adequate reconfiguration plan for the problem at \ runtime. In order to evaluate the effectiveness of the proposal, we illustrate it with a running example.
