Oriented Middleware " approach to HYSYS extensibility

and Scope of the Work The present work is part of a research project that is currently in progress at Tarragona with the main objective to develop an open and distributed architecture capable of supporting applications of collaborative intelligent techniques to control chemical processing plants. In this paper new ways to integrate external components with the HYSYS Process Simulator are explored, so that applications designed by developers can be distributed across TCP/IP based networks. The registration of applications with components generated by HYSYS requires the development of a module that links the process simulator with an external "Message Bus". To validate the proposed framework or architecture an intelligent control application based on Radial Basis Functions (RBF) neural networks has been conceived and implemented. This neuro-monitoring application based on Kohonen’s self-organizing maps (SOM) registers with a dynamic simulation running on HYSYS and uses the simulated output to learn the dynamics of the process. A third party library for the construction of intelligent agent systems is also used to demonstrate that the proposed framework can be easily integrated with other systems.
