Extended BPEL System for e-Engineering Framework Considering the Characteristics of Mechanical Engineering Services

Product development in mechanical industry can be defined as an engineering process based on the collaboration between different experts using various engineering services. The e-Engineering framework aims to integrate engineering services and mediate between them for the processing of the engineering process. The collaboration within the framework is very similar to a business process, in terms of web service composition. However, the existing web service composition system shows some limitations when dealing with engineering services. This paper presents a QoS-based web service orchestration system for the e-Engineering framework by analyzing the characteristics of engineering services which usually perform numerical analysis. The characteristics of the services are expressed in the form of constraint and selection specification.
