The data-driven newsvendor problem

The classical approach to the newsvendor problem is to first estimate the demand distribution (or assume it to be given) and then determine the optimal inventory level. Data-driven optimization offers an alternative, where the inventory level is dete

Heuristics for the stochastic economic lot sizing problem with remanufacturing under backordering costs

Autor: Huseyin Tunc, Onur A. Kilic

Publikováno v: European Journal of Operational Research, 276(3), 880-892. ELSEVIER SCIENCE BV

We consider a production system where demand can be met by manufacturing new products and re manufacturing returned products, and address the economic lot sizing problem therein. The system faces stochastic and time-varying demands and returns over a

In this paper we address the single-item, single-stocking point, non-stationary stochastic lot-sizing problem under backorder costs. It is well known that the (s, S) policy provides the optimal control for such inventory systems. However the computat
