Item Open Access Diffusion of geograpgic information system at municipalities in Istanbul(Chamber of Mining Engineers of Turkey, 2015-04) Çavur, M.; Özturan, M.; Karaduman, C.; İçli, Abdullah BeraThis study aims to develop a better understanding of diffusion of Geographic Information Systems within municipalities and examines the infrastructure of Istanbul municipalities and whether they are ready for this technology or not. This study uses two research methods: The first one comprises interviews with the experts of GIS in Turkey. The second one comprises questionnaires conducted with Geographic Information Systems - related departments of Istanbul municipalities. Data collected online have been analyzed by using descriptive statistics, reliability tests, Anova and regression to test the hypotheses. One of the findings is that almost half of the municipalities implement Geographic Information Systems without a vision or a plan for the future. Another finding is that Geographic Information Systems is mainly used to perform registration and maintenance functions instead of supporting the decision-making process. Finally, there is an optimistic expectation of municipalities regarding the use of Geographic Information Systems in the future.Item Open Access Examining proactive strategic decision-making flexibility in new product development(Wiley-Blackwell Publishing, 2012) Kandemir, D.; Acur, N.While strategic flexibility is widely accepted as a prerequisite for a firm's success, its application in strategic decision making to a firm's new product development (NPD) activities is limited to only a few studies. Furthermore, many organizations still have difficulties creating proactive strategic flexibility in their decision-making processes. Past research studies have largely ignored the relationship between strategic decision-making flexibility and firms' resources and/or capabilities and success in the context of NPD. This study advances strategic flexibility by adopting the proactive approach of NPD decision-making flexibility and by examining its role in translating organizational resources and capabilities into NPD success. This study draws upon the resources, capabilities (i.e., flexibility), and performance framework to show how proactive strategic decision-making flexibility plays a crucial role in developing new products that can create new opportunities and comply with market needs. Therefore, this research aims to (1) develop an operational definition of strategic decision-making flexibility and (2) propose a framework to understand the drivers and the subsequent new product performance outcomes of strategic decision-making flexibility. This study adopts the proactive perspective of strategic decision-making flexibility and defines it as a capability that enables firms to develop NPD strategies to respond to future changes in the environment. The analysis, based on data collected from 103 European firms, shows that that the effects of long-term orientation, strategic planning, internal commitment, and innovative climate on proactive strategic decision-making flexibility are significant. The findings indicate specifically the roles of both champions and gatekeepers, who infuse a firm's knowledge with a clear understanding of its resources, constraints, and market needs, thereby enhancing decision makers' motivation to behave proactively to precipitate transformation. The results also reveal a positive association between proactive strategic decision-making flexibility and NPD performance outcomes. As such, strategic flexibility provides firms with an ability to adapt to changing environments and to create new market opportunities, product, and technological arenas, and to deliver successful new products. When firms open new market, technological, and product arenas, they can easily foresee their new demands and changes and successfully deliver new products, meeting customer needs/demands, and offering benefits such as quality, cost, and timeliness. This study therefore provides a valuable reference point for future research in strategic decision-making flexibility in NPD.Item Open Access A game theoretical modeling and simulation framework for the integration of unmanned aircraft systems in to the national airspace(AIAA, 2016) Musavi, Negin; Tekelioğlu, K. B.; Yıldız, Yıldıray; Güneş, Kerem; Onural, DenizThe focus of this paper is to present a game theoretical modeling and simulation frame- work for the integration of Unmanned Aircraft Systems (UAS) into the National Airspace system (NAS). The problem of predicting the outcome of complex scenarios, where UAS and manned air vehicles co-exist, is the research problem of this work. The fundamental gap in the literature in terms of developing models for UAS integration into NAS is that the models of interaction between manned and unmanned vehicles are insufficient. These models are insufficient because a) they assume that human behavior is known a priori and b) they disregard human reaction and decision making process. The contribution of this paper is proposing a realistic modeling and simulation framework that will fill this gap in the literature. The foundations of the proposed modeling method is formed by game theory, which analyzes strategic decision making between intelligent agents, bounded rationality concept, which is based on the fact that humans cannot always make perfect decisions, and reinforcement learning, which is shown to be effective in human behavior in psychology literature. These concepts are used to develop a simulator which can be used to obtain the outcomes of scenarios consisting of UAS, manned vehicles, automation and their interactions. An analysis of the UAS integration is done with a specifically designed scenario for this paper. In the scenario, a UAS equipped with sense and avoid algorithm, moves along a predefined trajectory in a crowded airspace. Then the effect of various system parameters on the safety and performance of the overall system is investigated.Item Open Access Progression of color decision making in introductory design education(Wiley, 2017-04) Ertez Ural, Sibel; Akbay, S.; Altay, BurçakColor comprises both subjective and objective aspects within its contextual nature. Research on color design tends to explore this seemingly contradictory concerns from theoretical point of view, as well as architectural and design practice. The aim of this study was to observe subjective, intuitive or heuristic and objective, knowledge‐based or analytical attitudes toward color in design education. In the study 84 introductory design students were surveyed progressively to understand their color decision criteria after completion of three 2‐dimensional colored exercises, specific in terms of color education. Students' responses to open‐ended questions were coded according to the 5 categories, under 2 decision making processes derived from the literature; heuristic approach: preferential and symbolic criteria, and analytic reasoning: formal, thematic, and systematic criteria. A distinction between associative and emotional aspects of symbolic criteria was also revealed by the data analysis. The findings showed a shift from heuristic responses to analytic reasoning, as expected. Additionally, it is also investigated that students not only used heuristic approaches but also analytical components (formal and systematic) of color decision making in varying degrees as well, even before any color subjects covered. Thematic color decisions became a major part of the students' design considerations upon completion of color subjects. The observed increase in the number of color criteria interrelated by the students' among almost all categories explicated a complex decision making process particularly in color design and education. These findings were expected to lead to some further understanding in color decision making in design.
