Tomada de decisão multicritério aplicada a avaliação de vias urbanas.

Abstract

This paper deals with the presentation and study of methods of multidimensional analysis without conflicts and its applications to decision making at the individual level, with some topics related to collective decision making. The objectives of the work are: - to present methods of evaluating projects, from the most traditional to the most current; - show the limitations of certain types of analysis; - show the possibility of applying multicriteria analysis to urban transport programs; - implement the most common decision-making methods and buy them in the light of an application. The enormous series of impacts that alternative investments of transport facilities in urban areas can have, in terms of socio-economic development, highlights the advantages of the methods studied in relation to those traditionally used, that is, the purely economic analysis. Thus, it was initially proposed to expose the diversity and complexity of the factors involved in a process of evaluation and decision making of a transport project, justifying the reason for choosing the theme of the work presented. Then, in chapter I I, a critical analysis was analyzed economically, its theoretical basis and techniques used in the solution of problems related to transportation. Taking an evolutionary course in the exposition of methods in the evaluation of projects, the cost-effectiveness analysis comprising, mathematical formulation of the model, weighting processes and critical considerations is presented in chapter I I I. The proposed methods (ELECTRE I I and the denominated method Autran) that are objectives of this study are exposed in the following chapters. They aim to solve problems of decision making, incorporating socioeconomic factors. The methodology involves the use of judgments from representatives of local communities and governmental bodies at the federal, state and municipal levels and users of the transportation system. The case study to which the methods were applied includes multicriteria decision making regarding the implantation of six urban roads located in the municipality of Maceió. Ten criteria were taken into account being one quantitative (cost of implantation) and the other qualitative ones.
