许多研究已经进行，以尽量减少材料成本和提高效率，其中之一涉及使用遗传算法（GA）的材料选择。虽然GA提供了最好的解决方案，但它是计算密集型的。为了缓解这个问题，提出了一种简单的方法。选择船舶结构的主要部件--加强板作为本研究的优化模型，目的是使用所提出的简单方法使材料成本最小化。两个设计变量，板厚度（t）和板材料类型（m），选择特定的约束。采用简便的方法确定合适的板材种类，降低材料成本。此外，使用应力方程进行尺寸优化以产生最佳厚度。结果表明，该方法大大减少了船体结构的计算时间和材料成本。
Numerous studies have been conducted to minimize material costs and improve efficiency, one of which involves using the genetic algorithm (GA) for material selection. Although the GA provides the best solution, it is computationally intensive. To mitigate this issue, a simple method was proposed. The stiffened plate, a primary component of ship structure, was chosen as the optimization model for this study, with the objective of minimizing material costs using the proposed simple method. Two design variables, plate thickness (t) and plate material type (m), were selected with specific constraints. The simple method was used to determine the appropriate plate material types to reduce material costs. Additionally, size optimization was conducted using stress equations to produce the optimal thickness. The results showed that this method significantly reduced the computational time and material cost of the ship structure.
