This volume is dedicated to ProfessorChristos T. Papadopoulos, the founder of theconference series which has led to theformation of the Stochastic Models ofManufacturing and Service Operations(SMMSO) of which the contributors of thisvolume are members. His tireless energy andenthusiasm for this research area has giveneveryone involved a shining example tofollow. We trust that the contributions withinthe volume live up to his exacting standards.
“Do not say a little in many words but agreat deal in a few” –Pythagoras.
Preface
The origins and history of the research work underlying this volume stem from a se-ries of conferences which began in 1997 on the Island of Samos, Greece. In May ofthat year, Professor Christos Papadopoulos convened thirty-five research scientistsand practitioners from all over the world to share their knowledge of the applicationof stochastic modeling and processes in manufacturing systems. Figure 1 shows theparticipants from the first conference
His organization and skill at managing the first and subsequent conferences in-spired us all to follow him in his quest to encapsulate and extend the work to what it

has become in the present day. Christos is seated in the center of the photo, identifiedas #23 in Fig. 2.
Since 1997, there have been eight workshop/conferences every 2 years contin-uing the important seminal efforts of Christos. The conference/workshops held todate include:
• First Conference, Performance Evaluation and Optimization of Production Lines,Samos Greece, May 19–22, 1997
• Second Conference, Analysis and Modeling of Manufacturing Systems, TinosIsland, Greece, May 16–20, 1999
• Third Conference, Design and Analysis of Manufacturing Systems, Tinos Island,Greece, May 19–22, 2001
• Fourth Conference, Analysis of Manufacturing Systems, Samos Island, Greece,July 1–4, 2003
• Fifth Conference, Analysis of Manufacturing Systems- Production Management,Zakynthos Island, Greece, May 20–25, 2005
Preface ix
• Sixth Conference, Analysis of Manufacturing Systems, Luntern, The Nether-lands, May 11–16 2007
• Seventh Conference, Stochastic Models of Manufacturing and Service Opera-tions, Ostuni, Italy, June 7–12, 2009
• Eighth Conference, Stochastic Models of Manufacturing and Service Operations,Kusadasi, Turkey, May 28-June 02, 2011
During the seventh workshop in the Netherlands, the scientific committee arrivedat the acronym Stochastic Models of Manufacturing and Service Operations(SMMSO) as a characterization of the research topics covered by the workshop.The IX th conference is scheduled to be held in Germany at the end of May 2013.
While there is some overlap and natural integration, the following nine categoriesof research issues and concerns have emerged as the academic discipline of theconferences:
• [Performance Analysis (PA)]: Decomposition, queueing theory, Markov pro-cesses, exact and heuristic methods and simulation.
• [Production Systems (PS)]: Flow, transfer, and Bernoulli lines, material handlingsystems, open, closed, and mixed queueing network models.
• [Supply Chains (SC)]: Bullwhip effect, cross-docking, transportation systems.• [Production and Inventory Control (IC)]: Part-release mechanisms, make-to-
order/make-to-stock, push/pull systems, base stock, lean manufacturing, leadtimes, lot sizing.
• [Quality Control (QC)]: Inspection stations, defects, machine failures, feedback.• [Energy and Environment (EE)]: Sustainability, recycling, and waste manage-
ment.• [Optimization (OP)]: Buffers, servers, workload allocation, and routing.• [Sequencing and Scheduling (SS)]: Job shops, open shops, admission control,
release dates.• [Engineering Economy and Finance (EF)]: Evaluating alternatives, amortization,
cost analysis, and cost savings.
Figure 3 graphically depicts the subject matter discussed at most all of theSMMSO conferences and while the theory of stochastic processes, optimization,and production-inventory systems remain the academic underpinning for all the top-ics, it is the unique way in which the participants interact with these topics that haslaid the foundation for this volume.
We conceived the idea of this volume as a way to document the foundationsand academic principles of the SMMSO philosophy. This volume is designed tobe a tutorial introduction to many of the research topics and issues encompassedby SMMSO. Thus, the intended audience of this volume are those people fromacademia and the practicing world who deal with all aspects of stochastic modelingin manufacturing and service systems.
The topics included in the various chapters are ordered as depicted in Fig. 4 andsummarized below:

The photo in Fig. 5 is from the most recent meeting in Ephesus, Turkey in 2011.One of the founding participants and the invited speaker at the VIII conference,Professor Tayfur Altiok from Rutgers University, recently passed away. Tayfur isthe fourth person to the right seated in the top leftmost row in Fig. 5 and also shownin Fig. 6. He was a vital member of the first conference and the last meeting. He willbe sorely missed.
We trust that you will find in this volume a valuable set of tutorials and funda-mentals of the various research topics of the SMMSO universe.
