An approximation function of the fractal image regardless of black and white or colour can be considered as a fuzzy set. So the research of iterated fuzzy set system (IFZS) is necessary.

This paper uses the fuzzy system analysis to set up a regional L. R-L. P model, forecast with the parameter of the model and provide an auxiliary method.

This paper studies the addition model SAM in fuzzy system standard and analyzes the set function in the model.
