Evaluation of adaptive reuse of 4 buildings from the First National Architectural Period in Konya using TOPSIS decision support system

The concept of re-functioning is the preferred application within the protection approach by using the architectural cultural heritage of nations to transfer them to future generations. This application ensures that both historical buildings and cities are actively used and transferred to future generations. Within the framework of this main idea, it can be said that adaptable reuse applications are a preferred protection method for our cities to constantly change and transform and to adapt to changing needs. In this way, the cultural heritage of the cities we are in will be delivered to future generations in a healthy way and cultural continuity will be ensured. In this context, it is widely observed that especially historical buildings that have lost their function and historical structures located in historical city centers are given a new function or the scope of the function is expanded. Although the subject is such an accepted practice, when the application results are observed, it is observed that there are intervention decisions that cannot be agreed upon in terms of content. The most important of these decisions is how to choose the most appropriate function for architectural cultural heritage that cannot continue its function. While decisions are made based on intuitive and experience that varies from person to person in traditional decision-making processes, today, especially in parallel with the developments in statistical science, modern decision-making processes are needed in architectural practices. With this method, modern decision-making processes aim to obtain objective results in order to minimize errors arising from subjective decision-making processes and aim to reduce the error rate in the results. The TOPSIS (Technique for Order Preference by Similarity) Method used as a method in the thesis study suggests a method to search for the most ideal solution by ranking the best and worst alternatives, especially when choosing a function for architectural cultural heritage. An analytical and objective evaluation has been provided in the evaluations made with different expert opinions. In this context, differentiating from subjective evaluations, ways of making a qualified evaluation with the TOPSIS multi-criteria decision support system have been investigated. Within the scope of the study, the qualified decision-making process for the new function proposals of four (4) National Architecture Period buildings re-functioned in Konya City Center has been evaluated.
