** Description:** The task of construction of mathematical model of the homoeostatic system is decided, utillizing structurallyfunctional, approach at which structurization and working out in detail of model is conducted not in morphological, but only in a functional aspect and there is only a dynamics of level of glikemia on periphery, with the mediated account through him all of other substantial factors. On the basis of the offered mathematical model a method and criterion is developed diagnosticians which are utillized in the computer system of classification.
