The diagram titled “RESEARCH METHODOLOGY” is a flowchart that outlines each step of the research process. The diagram is divided into five steps, each representing a distinct phase in the methodology. The flow starts from the top with the first step, including a vertical oval in both the first and second steps labeled “Data Preparation and Collection.” The arrow-shaped box in the first step is labeled “Application and Criteria Identification.” The corresponding horizontal process boxes on the right are labeled “Literature Review,” followed by “Identification of Most Used Documents in Each Area,” and then “Evaluation Criteria Identification.” The second step has an arrow-shaped box labeled “Research Questionnaire.” The horizontal sequence to the right contains three boxes labeled “Target Population and Sampling Method Determination,” “Compilation and Distribution of Questionnaires,” and “Response’s Validity and Reliability Check.” A vertical oval is common in the third and fourth steps on the left side and labeled “Model Implementation.” The third step has an arrow-shaped box labeled “Criteria’s Relation Model and Weighting.” Three horizontally aligned rectangular boxes follow: “Fuzzy-DEMATEL Model Implementation,” “Evaluation of Model’s Results,” and “Validation of Model’s Results.” The fourth step has an arrow-shaped box labeled “Evaluation Model of Ranked Technologies.” The corresponding horizontal process boxes are labeled “Fuzzy-TOPSIS Model Implementation,” “Evaluation of Model’s Results,” and “Validation of Model’s Results.” The final section, labeled “Fifth Step,” includes one large horizontal rectangular box that spans the row, labeled “Evaluation of Final Results and Suggestions.” All process boxes and step indicators are shaded in light green, with black text and connecting rightward arrows between boxes. Each step’s progression continues downward, visually guided by large gray vertical arrows at the right edge.Overview of the research methodology process. Source: Authors’ own work
