Abstract:	A waste transfer station is a critical infrastructure for daily municipal solid waste management. In this paper, we showcase the modeling and simulation for a complex, largescale, and real domestic waste transfer station in Shanghai, China. Thanks to the actual operation situation and historical operation data, our work establishes a high-fidelity multistep transfer station simulation model. First, the holistic simulation model consists of two sub-models as per the actual operation rules of the transfer station. Without knowing the exact distribution form, a time probability density distribution model is established based on kernel density estimation and incorporated into the two sub-models. Second, built on the simulation model, two operational schemes are proposed to improve waste processing efficiency. The simulation results show that the proposed model can accurately capture the behaviors of the waste transfer system. Furthermore, the model carries out validation results and quantitatively analyzes the feasibility of operational schemes in a real-time manner to assist in decisionmaking for system operators.
