Sistema de apoio à decisão: avaliação de cenários de gestão integrada de resíduos sólidos urbanos domiciliares.
Resumo
The amount of waste generated by human activities associated with the decrease of
appropriate final disposal sites have been presented as one of the great challenges to be
faced by local administrations as well as by waste generating communities. Nowadays,
household solid waste management is analyzed according to Descartes and Newton
models, which are characterized by the separation and analysis of a system through its
parts, resulting in isolated and narrow sighted decisions. Aspects such as the lack of
technical training and financial resources contribute to this ongoing scenario.
Considering the exposed problem this work aims to develop a decision support system
to support the managers in the evaluation household solid waste management scenarios.
The method consisted in defining and delimiting the work field of decision support
system, followed by the construction of a conceptual model based on the acquired
knowledge. The model was then translated in action screens and decision workflows,
which were programmed in Delphi 6.0. The Extreme Programming (XP) methodology
was applied, meaning that programmer and cognitive agent act together in the code of
the system. Finally, the validation of the SIMGERE software in São Carlos (São Paulo
State) was made in two moments - first on program s usability, in other words, if the
system is friendly and easy understanding by user for treating of a new environment for
him and; second on the coherence of the results obtained by the simulation of the
municipal household solid waste management. For São Carlos case study, the landfill
lifetime projection, nearly 2 years, was coherent with the expected. However, the
economical simulation needs to be revised in order to better reflect the current
management model.
