内容简介：
This talk covers a couple of our recent work on acquisition planning in supply chain management. The problems are extensions of single period constrained newsvendor problem which takes into account both the supplier discounts and multiple periods. We formulate the problems as a Mixed Integer Nonlinear Programming model. A Lagrangian relaxation based approach is developed to solve the problems. Computational results show that the Lagrangian method can obtain very good solutions.
