Abstract

We consider a procurement problem where suppliers offer concave quantity discounts. The resulting continuous knapsack problem involves the minimization of a sum of separable concave functions. We identify polynomially solvable special cases of this NP-hard problem, and provide a fully polynomial-time approximation scheme for the general problem.
