Efes Beverage Group makes location and distribution decisions for its malt plants

We conducted a study for Efes Beverage Group to evaluate various sites as potential locations for new malt plants. We performed an economic analysis that showed the inferiority of some alternatives. To evaluate the remaining alternatives, we developed. a mixed-integer-programming model that considers both the location of new malt plants and the distribution of barley and malt. It considers the long-run effects of the decisions and minimizes the present value of total costs. Sakarya, Izmir, and Ankara turned out to be the best locations for new malt plants. Efes is currently using the model for distribution decisions. Based on our results and new developments that occurred since then, top managers are currently debating where and when to locate the new malt plants.

Analysis and improvement of the product delivery system of a beer producer in Ankara
Pamuk, S; Köksalan, Mustafa Murat; Gullu, R (Informa UK Limited, 2004-11-01)
We outline our analysis of the product delivery system of a major beer producer in Ankara, Turkey. We demonstrate a savings potential of up to 25% of distribution costs from the implementation of a number of suggested improvements, most notably that of reducing the number of weekly deliveries to a portion of the customers, and of constructing a geographical partitioning of the city that ensures a balanced distribution of the delivery workload over the days of the week. A geographic information system (GIS) ...
Using boolean- and fuzzy-logic-based methods to analyze multiple case study evidence in management research
Oz, O (SAGE Publications, 2004-06-01)
The case study method has been widely used as a research strategy in the management field. The issues of comparability and of generalizability when using this method, however, continue to raise profound challenges for researchers. Boolean- and fuzzy-logic-based methods offer a valuable basis for a contribution in this respect because they enable researchers to derive valid meaning from data and to introduce additional analytical rigor into case study research. Inspired by this opportunity, the present artic...
Analysis of an inventory system with advance emand information and supply uncertainty
Arıkan, Emel; Süral, Haldun; Department of Industrial Engineering (2005)
In this study we address a periodic review capacitated inventory system with supply uncertainty where advance demand information is available. A stochastic dynamic programming formulation is applied with the objective of minimizing the expected inventory related costs over a finite horizon. Three different supply processes are assumed. Under the all-or-nothing type supply process and partially available supply process, the structure of optimal policy is proved to be a base stock policy and numerical example...
Systemic Change in a Higher Education Institution: Inquiring into Organizational and Instructional Transformation
İpek, Ömer Faruk; Karaman, Abdullah Cendel (Springer Science and Business Media LLC, 2020-01-01)
© 2020, Springer Science+Business Media, LLC, part of Springer Nature.Changes often occur in organizational systems due to the technology, new methods, new understandings and emerging needs. This study examined the reasons, components, roles of the people involved and results of the systemic change process at a university preparatory department by using a self-initiated, prescriptive, and planned systemic change process. The aim of the study is to investigate how the planned systemic change initiative was p...
Operational fixed job scheduling problem under spread time constraints: a branch-and-price algorithm
Solyali, O.; Ozpeynirci, O. (Informa UK Limited, 2009-01-01)
This study addresses the operational fixed job scheduling problem under spread time constraints. The problem is to select a subset of jobs having fixed ready times and deadlines for processing on identical parallel machines such that total weight of the selected jobs is maximised. We first give a mathematical formulation of the problem and then reformulate it using Dantzig-Wolfe decomposition. We propose a branch-and-price algorithm that works on the reformulation of the problem. Computational results show ...
