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.
