Enterprise Application Integration (EAI), Service Oriented Architectures (SOA) and their relevance to e-supply chain formation
(Academic Journals, 2010) Rehan, Mohammad; Akyuz, Goknur Arzu; Information Systems Engineering; Industrial Engineering
The 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.

A Generic, Cloud-Based Representation for Supply Chains (SC's)
(Igi Global, 2013) Akyuz, Goknur Arzu; Rehan, Mohammad; Information Systems Engineering; Industrial Engineering
As 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.

A Generic, Multi-Period and Multi-Partner Cost Optimizing Model for Cloud-Based Supply Chain
(Igi Global, 2016) Akyuz, Goknur Arzu; Rehan, Mohammad; Information Systems Engineering; Industrial Engineering
Cloud 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.

Paradigm shift in supply chain management (SCM)
(American Society for Engineering Management, 2013) Akyuz,G.A.; Gursoy,G.; Industrial Engineering
In today's world, the way we do business is not the only changing phenomenon but also the pace of change is changing. The business is global, highly competitive, technology-intense, prices are market driven with shorter product life cycles, integrated processes starving to collaboration. Within this context, supply chain management (SCM) has earned its right place in the strategic management arena. Technology became the enabler for SCM development, making visibility, transparency and integrity possible among the SC partners. This leads the transformation of SC's from dyadic, material management oriented relationships into complex, collaborative, networked, web-enabled, extended architectures. With multiple, global actors and complex dependencies, enterprise borders vanish and enterprise-centric strategy development becomes insufficient. What defines success in such an environment is a network-centric, collaborative and holistic approach characterized by network level strategy development and decision making based on business intelligence with the partners. Integration of multi-function and multi-agent systems will be the main key performance index (KPI) for the SCM development. This is a radical paradigm shift in which collaborative long-term partnerships reign, managerial borders extend, and network-level results dominate the enterprise-centric results. Thus, this study provides a comprehensive discussion of this paradigm shift in SCM from organizational, technological, and managerial perspectives. Following the "leagile" philosophy, capabilities and advantages of lean and agile SCM can be achieved. In this paradigm, network level performance and risk management is the key for chain-level managerial control and trust among partners is the vital binding glue keeping the partnerships alive.

Supply chain in the cloud: Opportunities, barriers, and a generic treatment
(IGI Global, 2015) Akyuz,G.A.; Rehan,M.; Information Systems Engineering; Industrial Engineering
Cloud concept is directly related with the beyond-ERP integrity and collaboration across a number of heterogeneous Supply Chain (SC) partner infrastructures. The technology enables partners to form a collaborative SC community without the burden of significant IT investment. Cloud applications offer significant opportunities from SC perspective, and the assimilation of the Cloud Technology is not complete yet in the Supply Chain domain. It also involves various barriers from implementation perspective, as well as the concerns related with vendor lock-in, security, reliability, privacy and data ownership. This chapter provides a comprehensive coverage of the opportunities and barriers as well as the generic treatment from SC perspective. It also highlights how the cloud technology represents a perfect fit with the ideas of 'Collaborative Supply Chains', 'Business Process Outsourcing' and 'long-term strategic partnerships, which are the key themes characterizing the Supply Chains of today's era. This chapter reveals that the intersection of the topics 'Cloud computing' and 'Supply Chain' is a promising area for further research. Further studies in a multi-partner setting with respect to a variety of configurations, case studies and applications, as well as the security, reliability and data ownership issues are justified. © 2015 by IGI Global.
