...Xuanyi Bian; Yan Lin; Zongran Dong Pipe route design is one of the most complex and time-consuming steps in the ship detailed design. A large number of scholars have studied the optimization of ship pipe routes, but there is still a lack of a fast and effective method for the automatic design...

... methods are as follows. First, attention was paid to piping systems of multiple bulk carrier series of different sizes. The cost and length of the piping system as well as the similarity and the commonness of the modules and arrangements were considered. Second, to define an effective module that could...

... a lot of piping, and there are many materials as much as piping. For a shipyard that executes multiple projects at once, it is not easy to correlate so much piping material. A piping designer should check all materials based on his or her understanding of the design characteristics. However, depending...

...Zongran Dong; Yan Lin Pipe routing is one of the most time-consuming and complicated jobs in shipbuilding design. This article presents the automatic ship pipe routing method. To improve the efficiency of single pipe routing, the fixed-length encoding genetic algorithm (GA) is first used...
