Service Oriented Architecture (SOA) in Industrial Systems

Service oriented architecture (SOA) is attended as a design framework for realizing rapid and low-cost system development, easily modified system, and total system quality. SOA is mainly applied to business information systems using Web services standards and technologies, and is rapidly becoming a standard approach for enterprise IT systems. In industrial systems, SOA has been successfully applied such as SCM, order entry system, etc. However, in the low layer management and control systems, Web services cannot apply because of particular requirement. The specific functions needed to apply the concept of SOA to real-time system (response time, support of event-driven, asynchronous parallel applications, complicated human interface support, reliability, etc.). First of this talk, SOA will be briefly explained. Then, we will point out several issues arisen when the concept of SOA applied to the industrial systems. Finally, example industrial systems (business systems and command and control systems) applied SOA will be introduced.
