Abstract: With the acceleration of urbanization in China, it has become increasingly important to deal with the refuse collection and classification in the home community. How to process city refuse effectively and realize the recycling of resource has escalated from environmental problem to social problem, therefore, the construction of city refuse recycling logistics has become a matter of social economic and social benefit concern. The paper starts from constitution and construction of city refuse collection logistics network, and works out a practical simulation model for refuse collection and recycling logistics by classification of waste from five refuse collection sections in one residential community. The computer model is constructed and simulated by application of Witness Software; after simulation clock running for a period of time, the system is then optimized based on the results of simulation.
