Developing a Decision-Making Support System for a Smart Construction and Demolition Waste Transition to a Circular Economy

This research work aimed to develop a decision support system (DSS) to select the most appropriate concrete waste management method, which is the most critical issue in the construction industry. The research process began with the study of the current situation of concrete waste management problems. Related theories and literature were reviewed, and experts were interviewed in depth. After that, the Delphi technique and the fuzzy analytic hierarchy process (FAHP) were used to analyze the decision-making structure and consider factors related to the waste management methods. Then, the FAHP process was analyzed, calculated, and prioritized using MS Excel until the results were obtained. Finally, decision structures were shown, evaluated, and prioritized using a case study by a group of experts belonging to the Thai circular economy construction industry (CECI). The contribution of this research line in the DSS model is by analyzing, calculating, and finding the most appropriate alternative solution for the construction waste industry. Limitations, recommendations, and future research directions are also presented.
