摘要

When designing the layout of a ship engine room, which typically has limited space and numerous equipment, using the existing optimization algorithms often faces challenges, such as multiple optimization objectives, complex constraints, a very low proportion of feasible solutions, and convergence difficulties. To solve the above problems, this paper carries out a research on many-objective optimization system suitable for the layout design of ship engine rooms. Firstly, after comprehensively considering the main constraints, such as equipment intervals, maintenance space, and cabin aisles, we propose a hybrid algorithm that integrates the skyline algorithm and shelf algorithm to abstract the layout optimization problem into a packing problem. We complete the quantitative algorithms for overall space utilization, main aisle and maintenance aisle space, equipment maintenance and repair work efficiency, and piping length based on the proposed hybrid algorithm. Secondly, the optimization process is decomposed into a fractional-step optimization process consisting of an initial layout and a detailed layout. In the initial layout stage, we adopt the integer optimization coupled with the Tabu Search algorithm and NSGA-III algorithm and take the equipment layout order as design variables. In the detailed layout stage, the optimal result from the previous stage is taken as an initial solution, with the equipment spacing and cabin aisle width as design variables. Then, the optimization based on the NSGA-III algorithm outputs the Pareto solution set. Finally, we propose an optimal solution decision-making strategy suitable for many-objective optimization problems by combining subjective and objective weighting methods, achieving automatic and reasonable output of the optimal layout scheme. In order to verify the feasibility and applicability of the proposed optimized design system, we carried out an optimization design example for an actual engine room. The results show that the proposed optimization system can automatically generate the optimal layout scheme, and all performance metrics are better than the original manual layout scheme.
