Sürdürülebilirlik perspektifinden küresel bulanık TOPSIS metodolojisine dayalı BT proje yatırım değerlendirme çerçevesi

IT project investmen decision is a challenging process in the current technological dynamic environment because of the multiple criteria and requirements that need to be taken into account. The purpose of this paper is to design a suitable decision model to assess the IT projects, with a unique emphasis on the sustainability context. This study uses the MCDM technique with criteria selected and weighted according to sustainability aspects, including economic, environmental, social, and cultural. Consequently, the Spherical Fuzzy TOPSIS approach is applied to prioritize the IT projects based on their correspondence to the sustainability criteria. A theoretical background of Spherical Fuzzy TOPSIS is introduced to evaluate the sustainability effect of different undertakings. Reviewers of this study identified that Optimization on Flight Planning System as the most sustainable IT project among all the projects in this study and closely followed by the Carbon Offset Project. Based on these findings, this study concludes that projects that are most sustainable are those that directly influence the operational efficiency and resource usage within highly technological industries like the aviation industry especially if one considers long term gains such as; fuel conservation, integration, and effective information processing. To sum up, the conclusions give a clear signal that even though the high-cost projects imply a high level of risk, the achievement of sustainability concerns in many organizations' strategic objectives like operating efficiency, environmental sensitivity, and customer experiences would be enormously beneficial. Currently, there is a lack of information about sustainability analysis of IT projects in the existing literature. This study fills that void by considering sustainability issues in the assessment process and urging decision-makers to approach projects from this perspective. The proposed framework enables organizations to evaluate and select IT projects that best align with their sustainability strategies and operational constraints. Unlike previous studies, which often rely on traditional project evaluation criteria, this research introduces novel criteria such as Impact on Customer Experience, Flexibility, and Compatibility with Existing Systems, offering a more holistic approach to IT project evaluation.
