Application of Focus Group Method in Modified fuzzy DEMATEL technique (Integration of effective factors in lean and sustainable construction)
Fariba Shokoohi *
Abstract:   (180 Views)
The process of collecting valid and efficient data is a critical challenge in scientific research. Traditional methods of collecting quantitative or qualitative data, such as questionnaire surveys or expert interviews, are time-consuming, costly, and limited in scope. The COVID-19 pandemic has made these methods even more challenging due to social constraints. As a result, new communication technologies are needed to develop faster, less expensive, and more effective data collection methods. This study proposes the "Focus Group" method as an alternative for qualitative fuzzy-based studies. We provide a detailed history, instruction, and advantages of the approach, which overcomes research limitations in multidimensional, interdisciplinary, and ambiguous issues. The method integrates an efficient and systematic approach using online technology to collect expert opinions with high speed and accuracy, thereby reducing the possibility of omitted variables. We present an example of the Focus Group method's application in a study of the integration of influential variables in lean and sustainable construction using a fuzzy DEMATEL method. The results indicate that the Focus Group method can provide a deep, systematic, and efficient approach to data collection in qualitative research, allowing researchers to overcome various limitations and produce reliable and comprehensive results.
Keywords: Deep qualitative evaluation, Trapezoidal fuzzy DEMATEL, MCDA methods
