Summer Schools

Every “non-symposium” year ISIR organizes Summer Schools with the objective to bring together junior and senior researchersand to create an atmosphere for intensive discussion on the Ph.D. student?s research topics that fit under the general theme. This is usually accompanied by tutorial overviews on selected topics given by invited scholars of the field.

IMPORTANT DATES:

April 30, 2013: Submission of extended abtstract and senior researchers? application

May 15, 2013: Notification on acceptance

June 15, 2013: Registration deadline

June 30, 2013: Submission of working papers

There are no doubts that inventory research has many intersections with other disciplines that open new research perspectives. Therefore, the idea of this summer school is to bring together researchers from the field of inventory management as well as inventory modeling. This will facilitate research in emerging areas, as for example, innovative inventory control, integrated demand and supply management, sustainable supply chain management, behavioral aspects of inventory management, coordinated decision making, reverse logistics, inventory management in service operations, and humanitarian logistics. The 11th ISIR Summer School is organized by ISIR and Prof. Gerald Reiner (University of Neuchatel, Faculty of Economics and Business).

Objective

The objective of the summer school is to provide a place for Ph.D. students to present their research work and to discuss various aspects with fellow students and senior researchers. For each presentation given by a Ph.D. student two participants – one Ph.D. student and one senior researcher – will act as discussants. In addition to the presentations of Ph.D. students, senior researchers will give talks and offer tutorials.

A detailed program of the summer school is available through the summer school’s web site (http://www2.unine.ch/isir-summer2013).

Application and Registration

We invite Ph.D. students to apply to participate in the summer school by submitting an extended abstract (about 400?500 words) of their working paper until April 30, 2013. Ph.D. students will be notified about the acceptance of their paper before May 15, 2013. Upon acceptance, Ph.D. students are asked to submit a complete working paper until June 30, 2013.

Senior researchers who would like to give a presentation or act as a discussant are asked to send a note before April 30, 2013. Senior researchers are encouraged to participate together with a Ph.D. student.

Ph.D. students and senior researchers have to register before June 15, 2013. The registration fee for the summer school is 190 EUR and includes lunches, an excursion, the social program and a gala dinner.

Location and Venue

The summer school will be held at the University of Neuchatel (http://www.unine.ch), located in the heart of the city of Neuchatel, Switzerland.

9th ISIR Summer School

Changing Paradigm for Inventory Management in a Supply Chain Context

The Karol Adamiecki University of Economics

Katowice, Poland – 25 – 29 August, 2009

The ninth ISIR Summer School was organized at the Department of Business Logistics at the Karol Adamiecki Universiy of Economics in Katowice (Poland). The members of the organizing committee were Artur Swierczek (Ph.D.) and Edyta Klosa (M. Sc.), under the supervision of Prof. Danuta Kisperska-Moron.

The general theme of the workshop was: ?Changing Paradigm for Inventory Management in a Supply Chain Context?. The opportunity to participate in the workshop was addressed to a global group of young scientists (especially Ph.D. students) interested in logistics, supply chain management operations and operation research.

There were 20 participants who came from the Netherlands, Denmark, Germany, Slovenia, Hong Kong, Turkey, Hungary, Italy and Poland. The Ph.D. students presented the concepts of their doctoral dissertations or other research projects during several sessions. After that they answered the questions raised by other participants. The discussion was quite lively and content-related.

The other group of participants were senior researchers who moderated the discussion and conducted the session tracks. They also offered tutorials for the Ph. D. students and shared the practical and research experience pointing at significant problems of contemporary logistics and supply chain management. The senior researchers indicated else the potential dilemmas being ahead of young scientists, starting their academic carriers.

Visits in logistic companies operating in the Silesian region were another part of the workshop. During their visits in a distribution center and a brewery, the participants were able to confront their theoretical knowledge with practical business activities. Everyone also liked a very interesting social program which tightened the relationships between participants. Hopefully it will contribute to establishing the network of young scientists? jointly conducting international research projects, as well as exchanging and sharing their scientific concepts and ideas.

The following papers were presented by the PhD Students:

Soheil Abginehchi: Quality?s role in the sole versus dual-sourcing decisions

Joachim Arts: Efficient optimization of the dual-index policy using Markov Chain approximations

Bisheng Du: Investigating comparative advantages of advanced demand information in presence of heterogeneous demand

Cicekli Ural Gokay, Zalluhoglu Ali Erhan: Smoothing Bullwhip Effects in Supply Chain by Information Systems? Simulation Cases

Yick-Hin Hung: Matching short life-cycle product demand-supply by Trading Super Capacity Futures

Kristel Hoen: A simple and accurate approximation for the order fill rates in lost-sales Assemble-to-Order systems

Michał Jakubiak: Different methods of optimization of production cell in a factory

Daniel Kovacic: Some results on the multistage revers logistics in extended MRP model

Zsolt Matyusz: The Impact of Lean Practices on Inventory Turnover

Lorant Venter: Supply Chain Risk Management Strategies

July 30 -August 3, 2007
The 8th ISIR Summer School, titled ?New and Classical Stream in Inventory Management:   Advances in Research and Opening Frontiers?,
was held in Brescia (Italy) starting on July, 30th, to August 3rd, 2007.
The organization, supervised by Lucio Zavanella, was logistically supported by the Faculty of Engineering and obtained financial and logistic support by companies such as CSMT Gestione S.c.a.r.l., Brescia Trasporti, Cybertec, Metal Work and Legno Energia.
The School had the pleasure to welcome 36 participants: professors, researchers and doctoral students from 11 different countries throughout the world.
The School program, introduced on Monday by prof. H. Zijm (ISIR President-elected), scheduled the five-day event including tutorials, paper presentations and discussions, an industrial case and excursions. The appreciated research communications and tutorials marked the School programme: on Monday, Prof. A. Chik?n by the Corvinus University discussed the ?Stocks and Flows in the Supply Chain: a New Role of Inventories?; on Tuesday, Prof. P. Kochel (Chemnitz University) addressed the topic of ?Simulation (Optimization) in Inventory Theory?. Wednesday?s tutorial was presented by Prof. J. Wijngaard (University of Groningen), bringing the focus on ?Models for Production Planning and Control?. In the following two days, Prof. P. Kelle by Louisiana State University gave a tutorial on ?Healthcare Supply Chain Management: Specific Solutions and Challenges? (Thursday) and, finally, Prof. K. Inderfurth from the University of Magdeburg discussed the ?Contracting in Supply Chain Management? (Friday). Research focuses were broadened on Monday by the ISIR President, Prof. H. Zijm, University of Twente, who discussed the topic of ?Inventory Systems ? Design and Modeling? and, on Thursday, by the challenging speech on ?Humanitarian Logistics?  presented by Prof. C. Whybark, North Carolina University (Thursday).
Presentations of doctoral students and researchers always led to lively debates accurately coordinated by chairmen. It is worth noting the industrial case study described by Cybertec company and subsequently discussed by the participants.
Aside the lectures, the Summer School participants enjoyed their time in Brescia with two excursions: the first on Thursday to Sirmione, a well known and beautiful city on the Garda Lake, with its historic and naturalistic views, and the second one on Friday to the city of Brescia. The group discovered and tasted the history of the city walking along its streets. The two visits, as well as the entire course, represented an opportunity for people to meet each other and discuss on academic and non academic themes.
The organizers are extremely grateful to the participants for their fundamental contribution to the School success: the event succeeded in knowledge and friendship thanks to them all. A more detailed summary of the School may be downloaded at http://giano.ing.unibs.it/ISIR2007/

The Fifth ISIR Summer School was hosted by Robert W. Grubbström who received much support from his wife Anne-Marie and his team from Linköping Institute of Technology.

The school was organized in Loftahammar in the Archipelago of Tjust, a lovely resort on the Baltic Sea in the eastern part of Southern Sweden. There were about 30 participants from 12 different countries with a good mix of doctoral students and established academics.

The following presentations were given (in chronological order):

Attila Chikán: Supply chains in the global economy

Peter Köchel: The fleet sizing and allocation problem – the simulation optimization approach

Roger M. Hill: Ordering policies which take account of indivisible units of transfer

Zhiping Wang: Capacity-constrained production-inventory systems – using Laplace transforms and input-output analysis

A selection of the papers presented will be published as a Special Issue of the International Journal of Production Economics. In addition to the academic programme there was an extremely rich cultural programme. It started with an interesting visit of the Cultural Museum in Loftahammar with the mayor Holger Egmyr. We enjoyed boating through the Archipelago with a salmon lunch at Grindö made into a ritual by the Master of Ceremonies of the Nobel prize banquets Jan Hartman. We visited modern factories as Wienerbagarn where the works manager Fred Liljedahl presented automated production lines for cakes and pastries, and in an excursion to Västervik?s Slip-Naxos AB where VD Karl Barath discused and illustrated inventory control and product development in the grinding of such diverse products as steel, automotive components, tools and crystal glass. We had plenty of opportunity for close and productive contacts between the young and old participants in Källvik?s region and at the party on the wonderful estate of our host among others.

Bob has done a great job, all participants are pleased and grateful for this ISIR event of 2001. Despite the very high bar he laid the tradition of ISIR Summer School should and will be continued in 2003.

Sponsorship and support for this summer school was provided by

*ISIR

* the Operational Research Society

* the London Mathematical Society (the main UK mathematical society)

* the Institute of Operations Management (IOM, formerly BPICS, the British Production and Inventory Control Society)

Stockton Press (the division of MacMillan Publishing (UK) which publishes, among other titles, the Journal of the Operational Research Society) and the Visitor and Research Funds of University of Exeter’s School of Mathematical Sciences.

In fact three presenters at the school participated as a result of publicity provided by IOM and offered a distinctively practitioner’s view of inventory modelling.

In addition to the academic programme there was a ‘wine and nibbles’ reception, an organised walk through some of the older parts of Exeter including the cathedral and the city wall and a School dinner in the manor house in whose attractively landscaped grounds most of the buildings of the university campus are set.

Finally there was a day excursion which included a refreshing walk around the tors (hills) on Dartmoor (England’s largest national park) and a visit to Saltram House, a preserved National Trust house which was used for much of the location work for the film ‘Sense and Sensibility’. The school seems to have been enjoyed by the participants who had derived something both academically and socially from meeting and discussing ideas with colleagues researching in the same area. If there was a criticism to make it was that the programme was perhaps rather too full to allow sufficient time for a more extended discussion of the work being done by the research students and also that the programme structure had drifted somewhat towards a small conference format. Organisers of future summer schools may wish to consider how best to redress the balance in the programme.

The active participation of a number of senior researchers was greatly appreciated but particular thanks should go to Attila Chikán who found time in his particularly busy schedule to come and participate.

The Summer School has become an important part of ISIR’s activities, alternating as it does with the Budapest Symposium and moving from country to country. Robert Grubbström has kindly agreed to host the next Summer School in Sweden in August 2001 and we wish him every success.
