在城市规划设计中,对各种公建设施的定点、布局及其规模的确定,一般采用调查分析或套用定额指标,为较粗糙的计算方法。本文运用排队服务计算机仿真技术,实例计算社会经济生活中常见复杂多因素的“不确定模型”,进行城市公建设施的定量计算,提高了城市规划的科学性。 In the planning and design of cities, the determination of the fixed point, the layout and the scale of various public facilities are generally based on the investigation and analysis or the application of fixed quotas, which are relatively rough calculation methods. In this paper, we use the computer simulation technology of queuing service to calculate the “uncertain model” of common and complex multi-factors in social and economic life by examples, and calculate the urban public facilities quantitatively, which improves the scientificity of urban planning.
