Abstract
Solid waste management is a topic that has been drawing the attention of researches in operational research (OR) and system modeling in the last years. This article presents the development, validation and experimentation of simulation model using systems dynamics methodology, which allows users and managers to evaluate and analyze scenarios about the generation and disposal of urban solid waste. The developed model takes into account the following rates and information:rate of population natural increase (births and deaths), percentage of urban solid waste sent to each type of final disposal and the quantity of waste generated perinhabitant. The simulated scenarios take into account three distinct situations: (a) current scenario with varying rates, (b) current scenario with static rates, and (c) scenario with similar rates of the Netherlands. The model’s validation was developed through the analysis of future scenarios for a municipality in Brazil’s Southern. For the system modeling and development, Vensim - Ventana systems was used. With the generated results, the area managers may, in advance,evaluate and decide possible ways for improvements or adjustments in the management of municipal solid waste. Key words: Computational simulation, solid waste management, decision-making process, population growth.
