Re-Engineering Complex Process Control Systems Using SubProcess Agents.
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 4
Abstract
A process control systems design method whose architecture incorporates the use of agents, process agents and subprocess agents to further reduce the complexity of the system was developed. This is an improvement on an earlier architecture which employed only agents and process agents in its processing. An Algorithmic State Machine (ASM) chart of a complex system with or without a natural divide can be segmented into sub-units and a sub-process agent assigned to each sub-unit. Each of these sub-process agents ensures that systems performance information of each sub-unit is obtained and stored. These information would be used when evaluating system performance or for error tracking. The information also serves for process optimization and maintenance. This improved architecture is therefore one that employes state agents to execute the activities of each of the states in an ASM chart, sub-process agents to take charge of the state agents in one sub-unit and a process agent to co-ordinate the activities of the sub-process agents. The upper tank control system of a beverage blending machine was developed using this improved architecture.
