A multicriteria model for ranking best practices to mitigate making-do waste

Abstract

This article proposes a multicriteria model for ranking best practices to mitigate making-do waste, combining Fuzzy-Delphi and TOPSIS. The study aims to present a model that supports construction managers in ranking practices and assessing their impacts on efficiency and waste reduction, ensuring planned activities, confirming complete work packages, and mitigating waste. The approach incorporated decision-makers’ opinions, who evaluated which solutions have the greatest influence on securing activity prerequisites. These evaluations were integrated into a decision matrix involving multiple criteria, including subjective perspectives in classifying alternatives and the weights assigned. Results confirmed the occurrence of complete work packages capable of reducing making-do waste. The study concludes that the three solutions with the greatest influence are process standardization, event simulation, and lean practices. Future research includes enhancing the model by integrating and comparing rankings with other multicriteria techniques and incorporating additional solutions not assessed here.
