Logistics park functional zone phased layout method

Abstract

The invention relates to a logistics park functional zone layout method in the logistics system planning field, in particular to a logistics park functional zone phased layout method. According to themethod, the layer-by-layer recurrence thought is utilized to decompose a logistics park functional zone layout problem into the three phases of functional zone interrelation determination, functionalzone layout structure determination and functional zone position and shape determination, and an optimal logistics park functional zone layout scheme is solved in a united mode through layer-by-layeroptimization. Through the method, the logistics relation and the non-logistics relation among logistics park functional zones are quantified to obtain a functional zone comprehensive function, a functional zone layout structure is obtained in combination with a to-be-allocated functional zone selection process, an arrangement judgment process and placement rules, a multi-target planning model anda genetic algorithm are utilized to clearly quantify the relation among the functional zones and the relevant position relation among operation units, the positions and shapes of all the functional zones are precisely solved, the solving difficulty of a traditional layout planning model is lowered, and the design requirement of a logistics park functional zone integrated layout scheme under a stated objective is met.

Description

technical field [0001] The invention relates to a method for layout of a logistics park functional area in the field of logistics system planning, in particular to a method for the layout of a logistics park according to the functional division and stages. Background technique [0002] A reasonable layout of the functional areas of the logistics park can reduce the cost of internal material handling, improve the efficiency of land use, promote the full play of scale benefits, and optimize the smoothness of the connection between various functional areas. Accurate, quantitative, and green design of logistics park functional area layout method is the key issue of current research. There are three main types of existing logistics park layout methods: [0003] (1) A layout method based on simulation optimization. Ge Yanyan (2013) used the Em-Plant simulation platform to establish the internal structure model of the logistics park, and refined the principles of vehicle driving ...
