Abstract: Advanced control of complex industrial process is the frontier domain of information and control science.It is due to the complexity of its background that little essential progresses have been made yet in practical engineering or even on the theoretical basis.Therefore,it may be an intelligence choice for large scale complex industrial process control to take away of stepwise intellectulization.In this stepwise,there is three types of thought analogue.this paper tries to discuss thought analogue applying problem in complex industrial process modeling from fuzzy system theory and extension theory.
