生态环保城市街道微商业设施合理布局仿真

当前城市街道微商业设施布局方法存在指标显著度低和布局合理性低的问题。提出生态环保城市街道微商业设施合理布局方法,采用专家评价法和问卷调查法在城市系统需求、行为需求、心理需求和环境感知需求四个方面选取微商业设施布局的合理性指标,计算指标的权重,根据计算结果,将通行性、可达性和均好性作为合理规划城市街道微商业设施的重要指标。在考虑微商业设施布局通行性、可达性和均好性的基础上,构建微商业设施布局规划数学模型,将模糊理论引入模型中,建立模糊多目标非线性布局规划模型,设置约束条件,采用粒子群算法求解模糊多目标非线性布局规划模型,得到最优解,完成生态环保城市街道微商业设施的布局。仿真结果表明,所提方法的指标显著度高、布局合理性高。

Rational Layout Simulation of Micro-Commercial Facilities in Eco-Friendly Urban Streets

In current facility layout method of micro-commerce of urban street, the index significance is low. Meanwhile, the rationality of layout is poor. Therefore, a rational layout method with ecological and environmental protection is proposed in this article. Expert assessment method and questionnaire method were used to select rationality index of the facility layout in aspects of system requirement, behavior requirement, psychological requirement, and environment awareness requirement of urban. Weight of index was calculated. According to the calculation result, traffic ability, accessibility, and homogeneity were used as important index for reasonable plan of facility of the micro-commerce. On that basis, mathematical model of the plan of facility layout was built. The fuzzy theory was introduced to the model. Fuzzy multi-target nonlinear layout plan model was built and constraint condition was set. The layout plan model was solved via particle swarm algorithm and the optimum solution was obtained. Finally, the facility layout was completed. Simulation results show that the proposed method has high index and layout rationality.
