Optimization of the logistics node layout model based on SGA

This paper builds an optimal logistics node layout model with considering the land constraints and scale economy of freight based on the analysis of connotation of logistics node layout and does computational analysis to the model by SGA and numerical example simulation in Matlab, the analysis of the example shows that the algorithm can search to the global optimal solution of the problem quickly and has high excellence rate. It is an effective algorithm to resolve problem of optimization of the Logistics node layout model which takes scale effect into consideration.
