Aiming at these problems, a new agent-based service-oriented integration architecture was proposed for chemical process automation system. Web services were dynamically orchestrated on the internet and agent behaviors were built in them. Data analysis, model, optimization, control, fault diagnosis and so on were capsuled into different web services. Agents were used for service compositions by negotiation. A prototype system of poly(ethylene terephthalate) process automation was used as the case study to demonstrate the validation of the integration.展开更多

The popularity of the ESB has given rise to a number of commercial off the shelf (COTS) products as well as open source ESBs. In this study, we evaluated three open source ESBs and compared them both qualitatively and quantitatively. The empirical results were statistically tested to determine the statistical significance of the results.展开更多

It is a key for successful diagnosis and treatment to view accurate and up-to-date patient data in a single information dashboard in real time. But the fact is that many hospitals and healthcare providers today are struggling with legacy system or internally developed systems that cannot easily scale to support new interfaces; the plethora of inflexible point-to-point interfaces make changing in one system deleteriously impact other systems; some systems could not support information sharing; and the standards followed by different systems are not compatible to each other. This is making it increasingly difficult to meet the rapidly changing and demanding of healthcare service.展开更多

For the purpose of accommodating the characteristics of mold making companies, an event-driven enterprise service bus working as the heart of the platform is realized. A prototype system combining Web services, Business Process Execution Language （BPEL） and Web Ontology Language （OWL） is implemented. The clients and suppliers and the applications of mold making company are integrated in a loosely-coupled way through the services provided by the platform. Meanwhile the sharing of data and knowledge, and the coordination of business process are realized. By adopting the platform, a new approach is provided to solve the problem of design and manufacture integration for intra and inter mold making companies.展开更多

The usage of proprietary integration products results in the increased cost of enterprises. During the integration, the focus area has been found to often address only the functional requirements, while the non-functional requirements are side-stepped during the initial stages of a project. Moreover, the use of proprietary integration products and non-standards-based integration platform has given rise to an inflexible integration infrastructure resulting in adaptability concerns. Web services-based integration, based on open standards, is deemed to be the only feasible solution in such cases. This paper explains the performance analysis of enterprise integration in heterogeneous environments for the distributed and the transactional applications. The analysis presented in this paper is seen as a step towards making intelligent decisions well in advance when choosing the integration mechanism/products to address the functional as well as the non-functional requirements considering the future integration needs.展开更多
