Le dÃveloppement de l'Ãconomie avec la croissance de la population et l'augmentation correspondante de leur pouvoir d'achat entraÃnent une augmentation de la consommation et, par consÃquent, influencer des facteurs et des services qui sont directement liÃs à l'assainissement de la ville. Un exemple de ces services est la gestion des dÃchets solides municipaux. De ce contexte, la recherche est dÃveloppà sur le sujet de l'Ãvolution de la qualità et de la logistique inverse efficacità de dÃchets solides municipaux d'une ville. Par consÃquent, aprÃs avoir observà comment la logistique inverse est actuellement effectuà dans deux villes brÃsiliennes (Fortaleza dans l'Ãtat de Cearà et Osasco à SÃo Paulo), une optimisation de cette gestion de maniÃre quantitative et qualitative a Ãtà suggÃrÃ. En d'autres termes, cette optimisation suggÃre que les modÃles traditionnels de gestion actuellement utilisÃes dans l'administration publique, peut amÃliorer les performances et l'efficacità quand il est utilisà des outils mathÃmatiques, informatiques et la gestion appropriÃe. Un modÃle mathÃmatique a Ãtà formulà capable d'effectuer une analyse quantitative optimisà pour l'emplacement des installations au sein de la logistique inverse, puis il a Ãtà nommà le meilleur type de gouvernance pour ce modÃle pour Ãtre utilisà avec la haute performance et l'efficacitÃ. Pour optimiser les solutions dans le cadre des techniques de gestion des dÃchets solides municipaux sont utilisÃs programmation linÃaire mathÃmatique. Programme d'ordinateur mis au point pour cette Ãtude a Ãtà utilisà pour effectuer les simulations. L'efficacità et la polyvalence du programme d'ordinateur ont Ãtà ÃvaluÃs par une analyse de plusieurs exemples pour dÃterminer les installations de localisation optimisÃs à Singapour et à Osasco. La recherche opÃrationnelle est la base pour la construction de ce modÃle mathÃmatique tandis que le modÃle de gestion de partenariat public-privà est l'indication du type de gestion appropriÃe pour les affichages d'outils mathÃmatiques et informatiques mentionnÃs solutions optimisÃes dans le modÃle de gestion des dÃchets de la logistique inverse Solide proposÃe urbaine === The development of the economy together with the population growth and the corresponding increase of purchasing power generate an increase in consumption and, consequently, affect factors and services which have direct relationship with the basic sanitation services in a city. An example of such service is urban solid waste management. From this context, the research is developed in connection with the evolution in quality and efficiency of reverse logistics of urban solid waste. Therefore, after observing how reverse logistics is currently being executed in two Brazilian cities (Fortaleza, State of Cearà and Osasco, State of SÃo Paulo), quantitative and qualitative management optimization procedures are suggested. In other words, such optimization procedures suggest that traditional management models currently used in public administration can enhance performance and efficiency if appropriate mathematical, computational and managerial tools are used. A mathematical model was formulated capable to accomplish an optimized quantitative analysis for the location of facilities within the ambit of reverse logistics and, then, it was indicated which is the best type of public management so that the proposed model is used with high performance and efficiency. To optimize solutions in the context of urban solid waste management, linear programming techniques are used. A computer program developed for this research was used to perform the simulations. The efficiency and versatility of the computer program were evaluated through the analysis of several examples for determining the optimized location of facilities in Fortaleza and in Osasco. Operational research is the basis for the construction of the mathematical model while the public-private partnership management model is the indication of the type of appropriate management so that the aforementioned mathematical and computational tool may present optimized solutions in the proposed reverse logistics urban solid waste management model.
