Simulation techniques can be effectively applied to solid waste management systems, as an aid to understanding and analyzing existing systems or as part of the planning and design of new systems. Analysis of these systems using simulations can proceed at various levels of detail, depending on particular needs of the analysis (i.e., the questions for which answers are sought). This paper discusses the major system dimension variables for simulation of solid waste management systems, and how they can be related to each other to plan or understand a solid waste management system. Examples of the simulations at different levels of detail are included. In addition, the selection of appropriate simulation tools is addressed
