There exists a considerable knowledge of stochastic models and methods. Nevertheless, there is still demand forfurtherextensions,inparticularwhenitcomestocombininganoperationsview withotherbusinessperspectiveslikeastrongercustomerfocus. Thisbookcomprisesacollectionoffourresearchpaperstheauthorhasprepared duringhis timeasaPh.D.studentinthe “Logistics andOperationsManagement” program at the University of Vienna. The work’s innovation is the simultaneous consideration of classical performance measures and decision variables of manufacturing systems and the impact of customer-required lead times which varyamongdifferentcustomers. The contributions in detail analyze inventory, waiting time performance, and service-level measures under distributed customer-required lead times, both for single- and multistage manufacturing systems. The basic results are utilized to simultaneously optimize strategic and tactical means of a manufacturing system, i.e.,capacityontheonehandandwork-release rulesastacticalparameters onthe otherhand. Using simple queuing models, Klaus Altendorfer’s thesis aims at deriving analytical expressions for performance measures and insights derived from those. The obtained results will inspire future work on production control and manufacturing systems design with a particular emphasis on customer requirements. Munich,March2013 StefanMinner v ThiSisaFMBlankPage Acknowledgments The Ph.D. thesis, which is published with minor improvements in this book, was greatly inspired by one ofProf. Jodlbauer’s papers. The thesis was written during my time as a Research Assistant and later on as an Assistant Professor in his departmentattheUpperAustriaUniversityofAppliedSciencesinSteyr.Iwould liketothankProf.Jodlbauerforhissupportandfortheworkingconditionsenabling the generation of a Ph.D. thesis in his department. Furthermore, I would like to thank Prof. Hartl for the possibility to start my Ph.D. studies at the University of Viennaandforhisfurthersupport. IamespeciallythankfultomySupervisorProf.Minnerforhiscriticalcomments onmymanuscripts,leadingtoaconsiderableimprovementoftheresultsandtheir presentation.Thiscriticalreview hasenabledamuchdeeperunderstandingofthe conceptsusedandwillguidemyfutureresearchworkaswell.
