Article Citation - WoS: 2A Generic, Multi-Period and Multi-Partner Cost Optimizing Model for Cloud-Based Supply Chain(Igi Global, 2016) Akyuz, Goknur Arzu; Rehan, MohammadCloud technology in a multi-enterprise, collaborative context is one of the most promising topics at IT-Supply Chain (SC) intersection. Cloud comes with well-proven advantages and cost savings; enabling collaboration and business intelligence. Cloud transition is still on-going with individual enterprise-level transitions. However, collaborative paradigm dictates that entire network well-being is to be considered over enterprise-level concerns. Thus, handling the transition of a single enterprise is not sufficient for strategic network leverage. Planning and managing across multiple enterprises is required, taking into consideration various cost items and budget constraints. In this study, a multi-period multi-partner cost-optimizing model is developed for network-level management of cloud transition for a SC. The model produces an optimal transition plan, indicating timing of the transition for each partner to obtain the maximum cost savings across network over a specified planning horizon. The model proposed is generic, flexible and customizable for different sectors/settings.Article Citation - WoS: 2A Generic, Cloud-Based Representation for Supply Chains (sc's)(Igi Global, 2013) Akyuz, Goknur Arzu; Rehan, MohammadAs a very recent IT paradigm, Cloud Computing is gaining momentum and receiving more and more interest in literature. With various characteristics such as offering flexibility, cost reductions, platform independence and on-demand service, cloud approach opens up tremendous opportunities from Supply Chain (SC) perspective. However, extant literature reveals that adoption and assimilation of the technology is not mature in SC domain and cloud-based modelling initiatives are only recent. To fill this gap, this study discusses the opportunities of cloud computing from SC perspective and proposes a generic representation based on cloud philosophy. The proposed representation is conceptual, flexible and customizable, utilizing and highlighting the cloud benefits in a multi-partner setting. Therefore, this article is an answer to the research questions: "what are the opportunities of cloud philosophy for SC domain?" and "how can supply chains be represented generically based on cloud technology in multi-actor environment?". Contribution of this study lies in comprehensive treatment of cloud computing and supply chain intersection as well as the generic representation.Article Citation - WoS: 3Citation - Scopus: 6The Predictive Impact of Socio-Demographic and Behavioural Factors on Professionals' E-Commerce Attitudes(Academic Journals, 2010) Akman, Ibrahim; Rehan, Mohammad; Information Systems Engineering; Computer EngineeringThis paper first reviews the e-commerce issues in general and then gives a detailed report of the findings of a survey concerning how sociodemographic (gender and income) and behavioural (computer experience and average daily use of the Internet) factors influence e-commerce attitude of professionals. The survey was conducted among professionals from the government and private sectors. The results indicated that income is significantly related to the usage of e-commerce. Additionally, computer experience and average daily use of the internet were found to be significant in explaining usage reason for e-commerce users whereas the variable income was found to be significant in explaining nonusage reason for e-commerce nonusers.Review Citation - WoS: 7Enterprise Application Integration (eai), Service Oriented Architectures (soa) and Their Relevance To E-Supply Chain Formation(Academic Journals, 2010) Rehan, Mohammad; Akyuz, Goknur ArzuThe greatest challenge of e-supply chain formation is the integration of cross-application processes in a seamless manner. As platform independent, web-based interoperability are becoming key issues in web-based integration and supply chain formation, organisations are in search of architectural solutions to overcome these challenges. Thus, this paper focuses on the service oriented architectures (SOA) as the recent trend in cross-platform enterprise application integration. SOA paradigm is discussed in detail with special focus on e-supply chain formation. Findings indicate that SOA still appears as the most convenient paradigm to meet the challenges of today's e-supply chain formation requirements.Article Citation - WoS: 45Citation - Scopus: 71Requirements for Forming an 'e-supply Chain'(Taylor & Francis Ltd, 2009) Akyuz, Goknur Arzu; Rehan, MohammadIn today's digital economy, web-based integration of the enterprises to form an e-supply chain is a critical weapon for orchestrating the whole supply chain towards competitiveness. This paper intends to discuss the requirements for forming an e-supply chain from different perspectives, such as integration with the legacy systems, timing and prior presence of ERP (enterprise resources planning) systems, BPR (business process re-engineering) needs of internal and external business processes and business intelligence/decision support needs. A look at technical knowledge and structure to construct an e-supply chain is provided. Challenges involved in forming an e-supply chain are also briefly mentioned as a separate section in this paper. During the study, requirements are gathered by making a review of recent literature.Article Citation - WoS: 3Citation - Scopus: 2Designing Senior Graduation Project Course for Computing Curricula: an Active Learning Approach(Tempus Publications, 2010) Kilic, Hurevren; Kılıç, Hürevren; Koyuncu, Murat; Koyuncu, Murat; Rehan, Mohammad; Rehan, Mohammad; Kılıç, Hürevren; Koyuncu, Murat; Rehan, Mohammad; Computer Engineering; Computer Engineering; Information Systems Engineering; Information Systems Engineering; Computer Engineering; Information Systems EngineeringThis paper proposes an active learning-based design approach to senior graduation project courses for computing curricula. The proposed approach focuses mainly on course requirements including increasing the interaction between instructor and project team members; providing better and fair student/team performance assessment; encouraging students to practise life-cycle driven development; preparing students for role-based team-working; motivating students to communicate with experts from industry and supporting cooperation between students. It is observed that implementation of the proposed approach increases the student course satisfaction level while higher quality student projects are achieved.Article Impact of Job Requirements on Ict Curriculum(Tempus Publications, 2011) Canturk, Mehmet; Rehan, Mohammad; Computer Engineering; Information Systems EngineeringThis study presents an approach to address the issue of keeping curriculum content in synch with the changing demands; in other words dynamic curriculum delivery or dynamic curriculum updating based on a model. In this approach, the analysis of Information and Communication Technology (ICT) job data from the industry, and as well as the ongoing use of expert knowledge from the field of information science keep the ICT curriculum content up-to-date, relevant, and consistent with the educational goals of the universities, and students in a variety of educational and cultural contexts. A number of recommendations are put forward for educating students in Turkish universities in order to enhance their opportunities in the international job market.
