An algorithm for the parametrization of the cost vector of a particular class of linear programming problems with staircase matrices is designed. Formulas for the calculation of the intervals of stability are given, which are constructed by working only with the so-called ‘local’ inverses, instead of the inverse of the matrix A of the original problem.
