摘　　要：目的研究单管路自动布局在建筑环境中的应用,为减少管路设计时间,提高建筑管道设计质量.方法在三维空间管道正交敷设的前提下,提出一种基于概率选择的初始路径生成方法,改善的初始管道路径生成的质量,并设计面向管道布局的粒子群算法,进行全局路径优化,从而给出一种自动管道布局方法.结果该管道自动布局方法,能够成功避开障碍物,达到管道合理自动布局.在初始路径生成方法研究方面,通过与基于中间点法的管道初始路径生成方法对比分析可知,基于概率选择的初始路径生成方法与全局优化算法配合能够取得管道长度更短、弯头数量更少、布局时间更快的优化效果.结论在不影响建筑内环境的情况下,基于中间点法的管道初始路径生成方法的进行管道自动布局规划可行,基于概率选择的初始路径生成方法能够使管道自动布局做到美观、合理、经济、安全.In order to short the design time and improve the quality of pipeline design,the application of automatic layout of single pipeline in buildings is studied.With the pipeline being laid orthogonally in three-dimensional space,a method for generating initial route based on probabilistic selection is proposed to improve the quality of the generation of initial route.The particle swarm optimization（PSO） algorithm is applied to optimizing the route of pipelines,and an automatic pipeline layout method is presented.Using this method the obstacles can be avoided successfully and the pipeline can be reasonably laid out automatically.In the research of the initial route generation method,comparing with the method based on intermediate point,the proposed method based on probabilistic selection can short the pipe length,decrease the bends and make a quick layout.Without changing the internal environment of buildings,it is feasible that using the pipeline initialroute generation method based on the intermediate point to lay out the pipeline automatically,but the results of pipeline layout are not reasonable,economical,and safe enough.While the proposed method can make the layout of pipeline more decorated,reasonable,economical and safe.
