Considering the transfer function of garbage collection and transport, we should set up different ideal model to researchnecessarily. In this article we takethe refusing transfer station location of nanshan district in Shenzhen as an example and discuss the theoretical location coordinatespreliminary.By analyzing the problems and making reasonable assumptions, weestablished the multi-objective programming model: taking the transportation cost as a target,usingthe load capacity of the truckand all the rubbish must be cleaned up as constraint conditions, whether the trucks go from thedistrict transporting station to another as decision variable ,we established the multi-objective programming model which made the minimumtransport costs.By the help of MATLAB, LINGO software and EXCEL data exchanges, and logistics location
