This method is realized in the fuzzy expert system of risk estimation of the professionally conditioned diseases dynamics. The quantitative estimation of professional risks was determined on the basis of analysis of homoeostasis resistance estimation curves. A method can be used for the risk dynamics levels differentiation of wide circle of diseases.
