【Abstract】 In order to improve the efficiency of computer-aided pipe routing,the paper used genetic algorithm(GA) to optimize pipe routes.The routes may be the shortest if pipes avoid accessories,other pipes,inspection spaces etc.A fitness model for creating pipe routes was built.Routing engineering restriction rules were integrated in the model.Three modes of genetic operation were discussed.The GA flow chart for pipe routing was provided.The algorithm and its program were tested for their feasibility to create pipe rocdes creating path on 2D barrier mockups.Twenty or so typical pipes were automatically routed on a digital model engine which was divided into 3D grids.This proved the feasibility of intelligent pipe routing.更多还原
