MULTI-CRITERIA ANALYSIS IN SUSTAINABLE ENGINEERING DECISION MAKING

The problem of cities in relation to solid waste has been recognised as a significant issue especially in relation to civil construction. The environmental impacts caused by them are vast: air water and soil contamination disease dispersion etc. This work aims to investigate possible ways to minimize and/or avoid negative environmental impacts through the multi-criteria decision-making methodology known as the Analytic Hierarchy Process (AHP). It is a management tool developed in 1970 by Professor Thomas Saaty based on mathematics and psychology which helps to determine a correct decision. In this document it will focus on the technical analysis of a construction waste management model (RCCs) applied to a company in the construction industry 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 company that was studied.
