In this paper, we study production planning models for semiconductor wafer fabrication
facilities (wafer fabs) that consider both safety stocks at the finished goods inventory level …

The value of demand forecast information has been the subject of numerous studies in the
inventory literature, but has had limited application in production planning. This paper …

We study the performance of production planning models for wafer fabs in a rolling horizon
setting under stochastic demand modeled using the Martingale Model of Forecast Evolution …

Rolling horizon procedures, where an infinite horizon problem is approximated by the
solution to a sequence of finite horizon problems, are common in production planning …

We consider a single stage multi-item production-inventory system under stochastic
demand. We had previously proposed a production planning model integrating ideas from …

Multi-period capacitated production inventory problems are computationally challenging.
These problems have been researched extensively, and various approximations to solve …

Die vorliegende Dissertation entstand im Rahmen meiner Tätigkeit als wissenschaftlicher
Mitarbeiter an der FernUniversität in Hagen. Sie ist das Ergebnis von dort durchgeführten …

The previous chapters have motivated the need for more advanced anticipation functions
that can reflect, at least to a reasonable level of accuracy, the nonlinear relations between …

We consider a single stage multi-item production-inventory system under stochastic
demand. We had previously proposed a production planning model integrating ideas from …

Rolling-horizon production planning is based on the periodic update of forecasts and
decisions. In practice, companies implement a combination of deterministic models and …
