Abstract: Functional area layout of underground logistic terminal is an important part of urban underground logistic system planning so that it will indirectly affect the building and development of underground logistic terminal and even the whole urban underground logistics system. Based on genetic algorithm and Automod simulation platform, the functional area layout planning method of underground logistic terminal was built in order to avoid underground operation invalidation because of the illogical functional area layout. First by analyzing relative operation of underground logistic terminal, multi-objective 0-1 mixed integer programming model of functional area layout was built based on two indexes of relativity and transit cost between every two functional areas. Then the genetic algorithm was used to solve the mathematical model and find out the layout scheme after quantifying the indicators. Finally the final layout was gained by simulation and optimization based on Automod simulation platform. There was an example for proving the feasibility of the method. The results showed that the method was available to analyze the functional area layout impact and it was very important for decision-making of building the underground logistic terminal.

Keywords: Underground logistic terminal, modeling, simulation, automod and optimization
