Desenvolvimento e aplicação de método multicritério e miltidecisor na gestão dos resíduos sólidos urbanos da região metropolitana de Campina Grande/PB.

Abstract

One of the sectors that has received a lot of attention from researchers have with regard to sustainable the development and environmental quality refers the management of waste, these are present on various everyday situations, as well as in any and all economic process / production. An aggravating factor is that the generation of waste is proportional to the increase of population and production / consumption, reflecting an increase in both the amount and the volumes of those materials, as well as to the lower suited to their final disposal places, contributing to pollution of the given the high levels of contamination when these overlooked. On the face of it, this thesis sought to systematize a model based on the application of multicriterial methods and multidecisor for assessing the management of solid urban waste in Metropolitan Campina Grande through the selection of indicators which could support the conditions of efficiency, effectiveness and sustainability the studied system. For both, it was adopted as a methodological strategy, structuring the problem in a systematic way, in which several indicators were selected from the literature and adapted when necessary, to the reality studied, reaching a proposal for composed of 46 indicators, divided into 15 categories review and four dimensions. The indicators were a hierarchical structure, with their weights assigned through an applied questionnaire by a specialist in the area of management of solid urban waste. After this step, made use of the PROMETHEE II for partial ordering of the indicators, as well as the COPELAND to obtain a final list of the municipalities with perform better of RSU management, considering, for both, the preference of decision makers. Based on the application of the proposed model, we observed that target municipalities Search feature distortions that attempt inequalities in the evaluated indicators, which reflected the performance of municipalities. It is emphasized, that despite having obtained from a ranking between the municipalities, the scenario gotten is nowhere to be considered optimal, considering that was identified among the participants, indicators considered unsatisfactory for an adequate management of RSU. The methodology presented is appropriate and can be easily adapted to include more information / indicators, which may be used as a strategic tool to induce enhancements and optimizations in the urban waste management systems in the municipalities surveyed, establishing a diagnosis of the situation of waste that will contribute in making specific decisions for the problems.
