Abstract:

According to service need of electric power information, PoSOA is developed as a onestop integrated information service system based on serviceoriented architecture (SOA).Inevitably, there are varied services with similar functions and service indicators (response time, available time, cost, etc.), since they are from different provides. This makes services selection and replacement difficult. Driven by the requirements of PoSOA, it presents a QoS property description model that helps to customize the description set of QoS properties with relevant problem domain for different applications, and provide better supports to service selection and exception handling in serviceoriented applications. The model has been applied in power application system.
