Branch-pipe-routing approach for ships using improved genetic algorithm
Haiteng SUI,Wentie NIU
Frontiers of Mechanical Engineering 2016, Volume 11, Issue 3, Pages 316-323 doi: 10.1007/s11465-016-0384-z
Branch-pipe routing plays fundamental and critical roles in ship-pipe design. The branch-pipe-routing problem is a complex combinatorial optimization problem and is thus difficult to solve when depending only on human experts. A modified genetic-algorithm-based approach is proposed in this paper to solve this problem. The simplified layout space is first divided into three-dimensional (3D) grids to build its mathematical model. Branch pipes in layout space are regarded as a combination of several two-point pipes, and the pipe route between two connection points is generated using an improved maze algorithm. The coding of branch pipes is then defined, and the genetic operators are devised, especially the complete crossover strategy that greatly accelerates the convergence speed. Finally, simulation tests demonstrate the performance of proposed method.

Marine nuclear power equipment (MNPE) is crucial for the sustainable energy supply and carbon emission reduction during deep-sea resource exploitation. However, China has not achieved breakthroughs in the field of civil MNPE, although it has a good foundation in the nuclear and marine equipment industries. Based on the research of MNPE development practices in China and abroad, this study summarizes the advantages and technical sources of MNPE, analyzes future application scenarios and development trends, clarifies the strategic demand and problems of MNPE development in China, and proposes several development suggestions. Currently, MNPE is extending from military to civil use and from land to sea, and its main technical source is compact and integrated pressurized water reactors. In the near future, the equipment types of MNPE will focus on offshore floating nuclear power plants and nuclear-powered icebreakers. To promote the high-quality development of MNPE, it is necessary to clarify the major application scenarios of MNPE in China through top-level planning, formulate regulations, specifications, and supervisory systems through demonstration projects to match with practical development demands, and achieve breakthroughs regarding key technologies such as the construction of marine reactor systems and nuclear power platform assemblies.
