These are the models we know yet :

A : Augusta's 8-component model. Also, there is the Systemic variant, with dimensionality of functions, and a different flow system.
B : 16-component model which resembles Model A. (resembles Model A but has +/-)
G : Model which *seems* to resemble Model A, but really very different. (click here) and see article #32.
T : Physiological model with thresholds of excitation and inhibition. ILE would be +I- +L+ -S- -E+
X : Ganin's Model which contains the valuable functions (1256).
Ю : Model which contains the functions 1245. (also called Model J or Model Yu) ILE would be
AM : A weird dynamic model with gears which I don't really understand.
