Title: Preservation of Additive Convexity and Its Applications in Stochastic Optimization Problems

Speaker: Dr. Xiting Gong

Affiliation: Department of Systems Engineering and Engineering Management, The Chinese University of Hong Kong

Abstract

In this paper, we establish two new preservation results of additive convexity for a class of optimal transformation problems and a class of optimal disposal problems. For both classes of problems, there are multiple resources and the optimal policies provide different priorities to transform/dispose these resources; and we prove that the additive-convexity property preserves under the optimal transformation/disposal decisions. We demonstrate the applications of our preservation results to three important stochastic optimization problems in operations management: stochastic inventory management with remanufacturing, dynamic inventory rationing with multiple demand classes, and dynamic capacity management with general upgrading. This is joint work with Tong Wang.
