N2  - The dissertation considers am ultiperiod lotsizing problem on a complex production or inventory  system where demaqds are random. The problem is formulated as a stochastic network flow model  which also incorporates service level constraints. The model is approximated with a capacitated  and deterministic network flow problem with concave cost function. A scaling method is proposed  to solve this approximate flow problem. The method is efficient and produces an exact local optimum  flow. The Lagrange relaxation method is also applied to find lower bounds for the optimum system  cost. As an application, a stochastic coordinated multi-item lotsizing problem is considered and  .solved. Some computation experiments are carried out, showing the efficiency of the new methods  in handling practical problems
