The relations of parameters of interval-structure equations of working-capacity region and geometrical models of tolerance regions for interval and normal distribution laws are investigated. The method of estimating external actions on interval parameters of elements for interval coefficients of external actions is suggested. The method of forming branching interval-structure models of working-capacity region for non-linear output functions and interval coefficients of external actions. The relations of parameters of branching interval-structure equations of working-capacity region and geometrical models of tolerance regions for interval distribution law of parameters of elements and interval coefficients of external actions are investigated. The algorithms of assigning nominal tolerances for interval distribution law of parameters of elements and interval coefficients of externalactions are developed.
