AI 中文摘要
船舶内部布置是一个复杂的空间设计问题，在固定容积内相互竞争的功能会影响空间关系、质量分布、纵倾和稳性。探索这些权衡需要大量采用通用格式的布局方案，然而公开的总布置图稀缺、不一致且为二维形式。本研究开发了一个通用框架，用于在六类船型中生成概念性三维内部布置：散货船、油船、集装箱船、近海支援船、巡逻艇和游艇。每种布置均使用成对的体素网格和拓扑图进行空间与连通性分析。该框架通过三个实验进行评估：(i) 将50,000个生成的布置与23个重建的真实参考方案进行比较；(ii) 对每个船型家族的一个参考方案进行包络约束重建；(iii) 生成的布局对请求功能容积的响应。生成的设计空间在各船型家族的采样范围内与参考方案总体吻合。搜索替代的空间细分方案可改善所有船型家族的重建效果，体素精度达到75.5%。燃油和压载水的分配对请求容积的响应接近正比，而其他功能则取决于细分容量、舱室资格和离散分配。一个固定船体近海支援船的应用案例表明，相同的船体和请求功能方案可以产生不同的相邻关系和纵倾结果，在500个备选方案中有119个满足稳性和功能标准，其中包含5个非支配概念。研究结果支持跨船型家族和变化需求下的布局设计空间探索，空间组织在容积合规之外仍具有重要意义。生成器和概念性总布置数据集已公开发布，用于可复现的分析、基准测试和基于学习的设计研究。
英文摘要
Ship internal arrangement is a complex spatial design problem in which competing functions within a fixed volume affect spatial relationships, mass distribution, trim, and stability. Exploring these trade-offs requires many layouts in a common format, yet public general-arrangement drawings are scarce, inconsistent, and two-dimensional. This study develops a common framework for generating conceptual 3D internal arrangements across six vessel families: bulk carriers, tankers, container vessels, offshore support vessels, patrol vessels, and yachts. Each arrangement uses paired voxel grids and topological graphs for spatial and connectivity analysis. The framework is evaluated through three experiments: (i) comparison of 50,000 generated arrangements with 23 reconstructed real references, (ii) envelope-constrained reconstruction of one reference per family, and (iii) response of generated layouts to requested function volumes. Generated design spaces broadly align with references within each family's sampling range. Searching alternative spatial subdivisions improves reconstruction across all families, with voxel accuracy reaching 75.5%. Fuel and ballast allocations respond near-proportionally to requested volume, while other functions depend on subdivision capacity, compartment eligibility, and discrete assignment. A fixed-hull offshore support vessel application shows that the same hull and requested programme can produce different adjacency and trim outcomes, with five nondominated concepts among 119 of 500 alternatives meeting stability and programme criteria. The results support layout design-space exploration across vessel families and changing requirements, with spatial organisation remaining important beyond volume compliance. The generator and conceptual general arrangement dataset are released publicly for reproducible analysis, benchmarking, and learning-based design studies.
