Fuzzy method of construction of solving rules in systems screening diagnostics

A screening diagnostics systems critical rules building method, allowing medical algorithms correct description to be carried out has been suggested. The method is based upon the fuzzy sets theory. At membership function formation it is necessary to take into account that the nosological format and symptom relation may be expressed highly as well as lowly. Real diagnostic systems should take into consideration the symptoms value gradation in the context of the nosological format being considered and single symptoms obligation and non-obligation indicating means are necessary to be presented. A chronic diseases risk estimation critical rules building mathematical provision was suggested.
