产品设计是一项多学科活动，需要将并行工程方法集成到设计过程中，以确保产品质量的竞争优势。在并行工程中，田口方法展示了一种提高产品质量的有效设计方法。然而，田口方法直观地使用参数和水平来衡量设计参数值的最佳组合，这可能不能保证最终的解决方案是最优的。这项工作提出了一种集成程序，涉及田口质量设计过程中的神经网络训练和遗传算法模拟，以帮助寻找具有更精确设计参数值的最佳解决方案，从而改进产品开发。在产品形式替代方案的生成中也考虑了计算机图形学中的分形概念，以展示其在产品设计中的应用。所提出程序的一般方法的阶段包括：（1）田口实验设计程序的使用，（2）神经网络和遗传算法过程的分析，以及（3）设计备选方案的生成。以电风扇设计为例来描述所提出程序的开发并探索其适用性。结果表明，所提出的程序可以将产品设计工作的效率提高约 7.8%。预计所提出的设计程序将为设计人员提供更有效的产品开发方法。
Product design is a multidisciplinary activity that requires the integration of concurrent engineering approaches into a design process that secures competitive advantages in product quality. In concurrent engineering, the Taguchi method has demonstrated an efficient design approach for product quality improvement. However, the Taguchi method intuitively uses parameters and levels in measuring the optimum combination of design parameter values, which might not guarantee that the final solution is the most optimal. This work proposes an integrated procedure that involves neural network training and genetic algorithm simulation within the Taguchi quality design process to aid in searching for the optimum solution with more precise design parameter values for improving the product development. The concept of fractals in computer graphics is also considered in the generation of product form alternatives to demonstrate its application in product design. The stages in the general approach of the proposed procedures include: (1) use of the Taguchi experimental design procedure, (2) analysis of the neural network and genetic algorithm process, and (3) generation of design alternatives. An electric fan design is used as an example to describe the development and explore the applicability of the proposed procedures. The results indicate that the proposed procedures could enhance the efficiency of product design efforts by approximately 7.8%. It is also expected that the proposed design procedure will provide designers with a more effective approach to product development.
