Query: An Algorithm of Logistic Costs Minimization Under Constraints on Supply
  Volumes   A problem of minimization of delivery and storage costs of a product is
considered under constraints on volumes of delivery from each of the suppliers.
It is required to determine optimal volumes and times of product shipments. The
problem is NP-hard. In this paper, the problem is proved to be
pseudo-polynomially solvable and an algorithm for its solution is proposed.
