The procedures of the calculation of estimations for the lasting effects of interaction of factors on the basis of expert data are developed. The evaluations of the influence of some factors on others as the estimation of the changes in factors are interpreting as the objects of valued logic. The method of calculation of full temporary delays when modeling processes of interference of factors is considered. The object of examination is the method of expert analysis, which uses reflexive procedures of multi -valued logical conclusion for obtaining the transitive closing of the estimations of the mutual influence of the factors in question.
