In this treatment are considered coefficient perturbations in linear programming problems. For two cases the effects of these perturbations on the elements of the simplex-table are given. The first case consists in the linear dependence of the coefficients of one or several columns on one parameter, the second in the linear dependence of some columns of coefficients each on one parameter. It is shown, how formulas of perturbation according to the case of the polynomial dependence on one parameter and for the case of the simultaneous linear dependebce on some parameters can be formed. Finally and example of parametric linear programming with two columns of coefficients, which depend each on one parameter is presented.
