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 Ceará 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.
