AVAILABILITY MANAGEMENT IN CONFIGURE-TO-ORDER MANUFACTURING SYSTEMS Yöntem, Hüseyin Erdem M.Sc., Operational Research Supervisor: Asst. Prof. Dr. Sedef Meral December 2009, 98 pages In resource constrained supply chains, where demand is higher than the supply, the decision whether to accept or reject the customer order is a very critical task from resource planning and customer service level perspectives. Since the customers, in today‘s e-business environment, expect quick responses to their orders, some in-advance work has to be done before the arrival of actual customer orders, especially in configure-to-order (CTO) and make-to-order (MTO) production systems. Available-to-Promise (ATP) is a business function that is becoming the central management system for today‘s dynamic supply chains whose responsibility is to respond customer orders by considering the trade-off between front-end customer satisfaction and back-end capacity allocation. In this study, we propose an availability management approach that introduces push-based allocation planning by using order segmentation before the arrival of actual customer orders in CTO production environments. Moreover, a two-step order promising framework is introduced in order to increase customer service levels through giving certain or v tentative delivery dates immediately to customer orders before the batch, rule-based actual resource consumption processes. The proposed approach is applied to the real-life processes of an enterprise in order to analyze its applicability and evaluate the benefits that accrue. The results of the experiments prove that, the four-phased availability management approach contribute to both overall profit and customer service levels.

A Holistic Work System Framework (HWSF) Development Using Systems Thinking Ozalp, Egemen; Baykal, Buyurman (2014-07-31) Technology and Engineering Management Activities induced the awareness of Work Systems (WS) in Business Conduction. During WS activities and decisions settings, typically technical perspectives are espoused heavily. Although, remedies of this kind require holistic approaches, such approaches are not very common. One of the main reasons for this inadequacy is the lack of conforming guidance. In this work, the aim is to create a framework as guidance for WS activities. The Holistic Work System Framework (HWSF...
Finding the optimum route for transmission lines within GIS Öztürk, Tünay; Akyürek, Sevda Zuhal; Department of Geodetic and Geographical Information Technologies (2007) This study defines the optimum route planning for Electric Transmission Lines by Multicriteria Decision Analysis which is based on Geographic Information Systems (GIS). Determination of the optimum route is performed by using both the spatial and Euclidean distances between two points located on the Earth’s surface. The criteria needed to be taken into account to define the route of the Electrical Transmission Lines were evaluated with help of the experts who are doing this business in the available system ...
Organizational factors required for IT and business strategies alignment Altınışık, Said; Çetin, Yasemin; Department of Information Systems (2015) Previous literature strongly supports that the alignment of a firm’s information systems with business strategies leads to superior business performance and provides the firm a competitive advantage in the market. This study examines the antecedent factors of IT and business strategies alignment particularly for the Turkish context. Our research method in this study is embedded correlational model under the umbrella of mixed method research design. We derived the factors that were shown to contribute to bus...
Competition, Speculative Risks, and IT Security Outsourcing Cezar, Asunur; Cavusoglu, Huseyin; Raghunathan, Srinivasan (2009-06-25) Information security management is becoming a more critical and, simultaneously, a challenging function for many firms. Even though many security managers are skeptical about outsourcing of IT security, others have cited reasons that are used for outsourcing of traditional IT functions for why security outsourcing is likely to increase. Our research offers a novel explanation, based on competitive externalities associated with IT security, for firms' decisions to outsource IT security. We show that if compe...
Requirements Engineering for Cloud Systems: A Mapping Study Design Wanderley, Fernando; Souza, Eric; Goulao, Miguel; Araujo, Joao; Cysneiros, Gilberto; Misra, Ananya (2017-07-06) Cloud Computing gets increasingly established in industrial practice as an option for modelling cost-efficient and demand-oriented information systems. Despite the increasing acceptance of cloud computing within the industry, many important questions remain unanswered. Issues related to the best software architectures decisions for cloud-based systems are faced with the question of appropriate techniques applying at early phase like requirements engineering. The goal of this paper defines a design of a mapp...
