Abstract :

Introduction: The waste generation is the product of different human activities that have been transformed because of the change of life style and multilateral development. By progression in science and technology, waste management has been reviewed scientifically. Within the eight branches of functional elements of municipal solid waste management system, generation, collection and transportation have especial importance. The significance of waste generation is due to being the first loop in the chain of recycling and reducing production is the base of comprehensive solid waste management pyramid .Otherwise the greatest part of costs for managing solid waste systems relates to collection and transportation of wastes. Materials & Method: In this paper we described municipal solid waste management system and dynamic modeling methodology. After that we reviewed the literature research about dynamic modeling of municipal solid waste management systems. In the next step, we illustrated a dynamic model for generation, collection and transportation of wastes in the city of Tehran. Then we analyzed the findings from the base run of model and examined that with validation tests to gain accredited model. Result& Discussion: After achieving a valid model the improved scenario have been built based on 3R techniques and policy and sensitivity analysis. In Tehran city, emphasis on reducing production and decreasing of per capita waste generation, awaken citizens and officials on necessity of separation wet and dry wastes in era and Effort to improving the performance of Dry waste separation plan are the best options to manage generation ,collection and transportation  wastes  subsystems .
