The paper presents a bundle method for constrained convex optimization. Instead of using penalty functions, it shifts iterates towards feasibility, by way of a SIater point, assumed to be known. Besides, the method accepts an oracle delivering function and subgradient vaIues with unknown accuracy. The proposed approach is motivated by a number of applications in column generation, in which constraints are positively homogeneous - so that 0 is a natural Slater point - and an exact oracle may be time consuming. Finally, this convergence analysis empIoys arguments which have been little used so far in the bundle community. The method is illustrated on a number of cutting-stock problems.
