船舶管路自适应导向步进优化方法研究
Research on adaptive guided step optimization method for ship pipeline
摘要
Abstract
To improve the efficiency of ship pipeline layout optimization and design,an improved whale optimization algorithm that integrates population evolution rate and Levy flight-LEWOA is proposed.The ship pipeline layout space and equipment are mathematically modeled,the evaluation functions based on the characteristics of ship pipeline layout are designed,and an adaptive guided step coding method is proposed to improve the operational efficiency of algorithms under the grid method.The initial population quality of pipeline paths is improved by bending mode,and the global and local search capabilities of the algorithm are effectively balanced by combining population evolution rate and Levy flight.A method to find branching points of branching pipelines is proposed using Fibonacci sequence.The robustness and accuracy of the algorithm are verified by comparing simulation cases of single pipeline and complex multi pipeline,which has certain guiding significance for the selection of ship pipeline layout schemes.关键词
