Evaluating the location of regional return centers in reverse logistics through integration of GIS, AHP and integer programming
(University of Cincinnati, 2015) Acar,A.Z.; Önden,I.; Kara,K.
Reverse logistics network problems are accepted as sophisticated research areas in the existing literature due to difficulties of the prediction of the material flow in the network and the conflicting objectives of minimizing total cost and energy consumption while maximizing customer satisfaction and control of the pollution. There are different approaches to dealing with the difficulties of the problem, yet these approaches overlook the geographical aspect of the issues. In this paper, a reversed network of a governmental organization is evaluated. A methodology is proposed that integrates Analytic Hierarchy Process, Geographic Information Systems and integer programming to determine the locations of the return centers and to deal with the complicated structure. Population, airport locations, maritime facilities, railroad lines and highway lines are accepted as the decision criteria. Based on these decision criteria, suitability levels of the candidate cities are calculated. A closed-loop supply chain is taken into consideration and reverse functions of the chain are evaluated with the proposed methodology. Finally, the locations of regional return centers are determined. © INTERNATIONAL JOURNAL OF INDUSTRIAL ENGINEERING.

Logistic performance development of the countries on the path along the new silk road
(Institute for Transport Studies in the European Economic Integration, 2015) Acar,A.Z.; Bentyn,Z.; Kocaoʇlu,B.
The one of the connections between Asia and Europe leads along the path throughout countries: Kazakhstan, Azerbaijan, Georgia, and Turkey. The changing economic environment creates different local strategies to elicit the development of logistical infrastructure in those countries. The purpose of this paper is to present the changes over time measured by the logistic performance index. Thanks to that it is possible to create the path of progress in achieving the desired performance. As a result of the common effort of countries increasing the efficiency of logistic operations, the realization of reliable Euro-Asian interconnections may become reality.

Process development in customer order information systems to gain competitive advantage: A SME case study
(Inderscience Publishers, 2016) Kocaoglu,B.; Acar,A.Z.
In today's intensely competitive business environment improvement in sales order cycle time is vital for the company's success. Controlling credits and measuring payment, especially crucial for a SME to manage its cash flow more efficiently, and to gain customer satisfaction, as well. So, the order management process should be robustly designed and optimally controlled. Thus, to gain superior performance firms must initiate new process development activities using information systems in order to find new methods of improving sales order cycle time. The purpose of this study is to develop a more efficient order management process for a SME also that can be generalised for the others. This process development aims to strike an appropriate balance between measuring lost times and managing customer credit limits. In this study, after analysing the pre-sales process of a focal SME, a framework is developed that is compatible with the current ERP system and can measure required metrics.

Strategic Orientations and Their Effects on Firm Performance in Turkish Family Owned Firms
(Springer International Publishing, 2011) Altindag,E.; Zehir,C.; Acar,A.Z.
In this day and age, family based companies need more flexible and faster organization structures to respond effectively to the customers’ growing various type of needs in the dynamic markets. Family owned firms use more strategic tools to increase their firm performance. These tools include some strategic orientations as customer, innovation, entrepreneurship, and learning orientations. This new concept requires new strategic alternatives for the companies. This study tries to explore the relationship between effects of strategic orientations levels on firm performance and the family firms in Turkey. As total of 280 questionnaires are collected from the managers whom have key roles in the organizational structure in different scaled family owned firms. After the findings are examined by data reliability and exploring factor analyses, regression analyses are used for evaluating the relations between the dimensions. Consequently, it is presented the positive effects of strategic orientations on the qualitative and quantitative performance of family firms. In the conclusion section, various suggestions are offered for academicians and managers. © 2010, Eurasia Business and Economics Society.
