document: Adaptive scheduling of batch servers in flow shops Batch servicing is a common way of benefiting from economies of scale in manufacturing operations . Good examples of production systems that allow for batch processing are ovens found in the aircraft industry and in semiconductor manufacturing . In this paper we study the issue of dynamic scheduling of such systems within the context of multi-stage flow shops . So far , a great deal of research has concentrated on the development of control strategies , which only address the batch stage . This paper proposes an integral scheduling approach that also includes succeeding stages . In this way , we aim for shop optimization , instead of optimizing performance for a single stage . Our so-called look-ahead strategy adapts its scheduling decision to shop status , which includes information on a limited number of near-future arrivals . In particular , we study a two-stage flow shop , in which the batch stage is succeeded by a serial stage . The serial stage may be realized by a single machine or by parallel machines . Through an extensive simulation study it is demonstrated how shop performance can be improved by the proposed strategy relative to existing strategies
