WPS (web processing service) is the specifications launched by OGC organizations for dealing with space data, which is different from the conventional Web Service. There aren't dedicated workflow environment for WPS service framework, and support of workflow environments in WPS application is the key technical challenges. Some of the workflow environment, such as Shark, still lack of effective implementation...
When a business process fails to deliver the quality of service (QoS), it is necessary to identify the faulty services that cause the problem. In this paper, we present a framework for diagnosing QoS problems in SOA. A set-covering algorithm is used to select the locations of run-time service data collection, or probes. The framework then creates a dependency matrix to denote the relationships between...
In SOA, services may become volatile and fail to deliver the quality of service as requested by users. In this paper, we present an approach for repairing failed services by replacing them with new services and ensuring the new service process still meets the user specified end-to-end QoS constraints. An iterative structural inspection algorithm is designed to produce reconfiguration regions that...
As a business process is essential in running an enterprise, this paper aims toward improving software architecture by extracting business-relevant semantics from business logic and transforming them as important elements that need to be molded and represented in software architecture. This allows for the development of a business process-oriented software architecture (BPOSA) that can support smoother...
