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

Abstract

This paper proposes a multicriteria decision-making model, combining the Fuzzy-Delphi and TOPSIS techniques, to support managers in making decisions to determine management practices with the best impact to improve efficiency and reduce waste, ensuring the prerequisites of planned activities. The approach combined the opinions of the decision makers interviewed and subsequently integrated into a decision matrix involving multiple criteria, the subjectivity of the views in the classification of alternatives and the assigned weights. The proposed model showed the diversity of application of the model and the importance of the results, ensuring a complete kit for reducing make-do waste. It is concluded that the three best management solutions that most influence the guarantee of prerequisite activities are process standardization, event simulation and Lean practices.
