Multi-Kriterien-Analyse Bei Der Entscheidungsfindung Im Bereich Des Nachhaltigen Ingenieurwesens

The problem of cities regarding solid waste has been recognized as a significant issue, particularly in relation to the construction industry. The environmental impacts caused by this are enormous: air, water, and soil pollution, the spread of diseases, and so on. The aim of this work is to explore possible ways to minimize and/or avoid negative environmental impacts through a multi-criteria decision-making method known as the Analytic Hierarchy Process (AHP). This management tool, developed by Professor Thomas Saaty in the 1970s, is based on mathematics and psychology and helps in making sound decisions. This document focuses on the technical analysis of a model for the disposal of construction waste (RCCs), which was applied to a construction company in the city of Teresina, Piauí, including some aspects relevant to the case study. The modeling results showed a favorable consistency index for the alternatives presented within the scenario of the studied company.
