An agent-based service-oriented integration architecture for chemical process automation

In reality, traditional process control system built upon centralized and hierarchical structures presents a weak response to change and is easy to shut down by single failure. 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.

This paper proposed a new agent-based service-oriented integration architecture for chemical process automation system to quickly response and well integrate the old systems. Different operations/analysis modal are capsuled into web services and these services negotiate using agents. Though it is a hard work to integrate all the old systems, a prototype system has been given to illustrate the Architecture.Figure optionsDownload as PowerPoint slide
