Title: Radio frequency identification (RFID) technologies for locating warehouse resources: A conceptual framework Authors: Hassan, M; Ali, M; Aktas, E Abstract: In the supply chain, a warehouse is a crucial component for linking all chain parties. It is necessary to track the real time resource location and status to support warehouse operations effectively. Therefore, RFID technology has been adopted to facilitate the collection and sharing of data in a warehouse environment. However, an essential decision should be made on the type of RFID tags the warehouse managers should adopt, because it is very important to implement RFID tags that work in warehouse environment. As a result, the warehouse resources will be easily tracked and accurately located which will improve the visibility of warehouse operations, enhance the productivity and reduce the operation costs of the warehouse. Therefore, it is crucial to evaluate the reading performance of all types of RFID tags in a warehouse environment in order to choose the most appropriate RFID tags which will enhance the operational efficiency of a warehouse. Reading performance of active and passive RFID tags have been evaluated before while, semi-passive RFID tag, which is battery-assisted with greater sensitivity than passive tags and cheaper than active tags, has not been examined yet in a warehouse environment. This research is in- progress research and it seeks to (i) provide a general overview of the existing real-time data management techniques in tracking warehouse resources location, (ii) provide an overall conceptual framework that can help warehouse managers to choose the best RFID technologies for a warehouse environment, (iii) Finally, the paper submits an experiment design for evaluating the reading performance of semi-passive RFID tags in a warehouse environment.

Title: The influences of social e-shopping in enhancing young women’s online shopping behaviour Authors: Dennis, C; Morgan, A; Wright, LT; Chanaka, J Abstract: The background to this paper is that shoppers, particularly women, are motivated by a variety of different reasons, including socialising and enjoyment. Despite the growth of Internet retailing (e-retailing), these social needs are largely unmet in e-shopping. In the high street, women do most of the shopping but online shopping (e-shopping) tends to be dominated by male shoppers. At the same time, social networking is growing fast and is especially popular amongst young females. The purpose of this paper is to draw on prior research about why people shop in order to explore the concept of social e-shopping, based on combining e-shopping with social networking. We propose that shoppers, particularly young females, will prefer social e-shopping to traditional e-shopping. We carried out a qualitative study for our propositions with a comparison experiment, semi-structured questionnaire and focus group, to compare a traditional e-shopping website with a social e-shopping one. The findings reveal that young women prefer social e-shopping sites. Both utilitarian and hedonic young adult female shoppers found social e-shopping enjoyable and useful. However, although many participants found the social e-shopping site more difficult to use, this was outweighed by their enjoyment of the site and its usefulness. The study demonstrates the potential value of the concept of social e-shopping for future research. The findings have practical implications in that social e-shopping can be a valuable strategy for e-retailers wanting to gain competitive advantage and to positively increase the e-shopping behaviour intentions of young women. This study is original in being the first academic study of which we are aware to propose the concept of social e-shopping and examine the influences of social e-shopping on consumer shopping behaviour.

Title: Analyzing competitiveness of automotive industry through cumulative belief degrees Authors: Kabak, O; Ulengin, F; Onsel, S; Ozaydin, O; Aktas, E Abstract: This study aims to analyze the automotive industry from competitiveness perspective using a novel cumulative belief degrees (CBD) approach. For this purpose, a mathematical model based on CBD is proposed to quantify the relations among the variables in a system. This model is used to analyze the Turkish Automotive Industry through scenario analysis. Description: Copyright @ 2012 The European Mathematical Society

Title: İstanbul`da itfaiye istasyonu yerlerinin seçimi için yeni bir model - Fire station location selection for Istanbul Authors: Aktas, E; Özaydin, Ö; Ülengin, F; Önsel, Ş; Agaran, B Abstract: Özellikle acil hizmetler veren polis, hastane, itfaiye gibi kurumlar için yer seçimi büyük önem taşımaktadır. Uygun bir yer seçimi gerçekleştirilmediği takdirde bunun sonuçları insan hayatını tehlikeye atabilir niteliktedir. İstanbul gibi büyük metropollerde, artan nüfus ve trafik yoğunluğunun yanı sıra bir de metropolün deprem kuşağında olması durumunda, itfaiye araçlarının olay yerine en hızlı şekilde ulaşması hayati önem taşımakta; bu da itfaiye istasyonu yerinin etkin seçimine kritik bir rol yüklemektedir. Bu çalışma; İstanbul Büyükşehir Belediyesi tarafından kararlaştırıldığı gibi, itfaiye teşkilatının her bölgeye en çok beş dakikada erişebilmesi ve kapsama alanının %100 olması hedeflenerek yeni kurulacak olan itfaiye istasyonlarının küme kapsama modeli yardımıyla konumlandırılmasını içermektedir. Bu amaçla bir tamsayı programlama modeli kurulmuş, coğrafi bilgi sistemlerinden elde edilen verilerle model çözülmüş, seçilen yerler için itfaiye kurulması durumunda yangın hizmet düzeyinin değişimi incelenmiştir. - For emergency services such as ambulance systems and fire departments, location selection plays a critical role due to the direct impact of these services on human lives. Timeliness plays a primary role in location selection decision of fire stations for large metropolitan cities such as Istanbul with increasing population with a high level of congestion coupled with an imminent earthquake risk. This study is based on a set-covering model for locating new fire stations, which target to serve each area at most in five minutes and improve their coverage area to 100% for Istanbul Municipality Fire Department. Accordingly, a set-covering model is built and solved using the data retrieved from geographical information systems. Finally the change in service level with proposed fire station locations is investigated and further suggestions are provided.
