Interaction balance method for large-scale industrial processes with fuzzy parameters

Considering the difference between model and reality, model coefficients of large-scale industrial processes are treated as fuzzy numbers, and an interaction balance method based on fuzzy model is proposed. Three types of interaction balance method: general interaction balance method, interaction balance method with global feedback and interaction balance method with double iterative techniques are studied. Simulation shows that the method provides a faster convergence and better objective function. Furthermore double iterative techniques with fuzzy parameters is the coordination method that requires the smallest number of on-line iterations so far.
