田口方法的适用性研究

Research on the Applicability of Taguchi Method

摘要:

基于1989-2019年的75篇国内外田口方法研究文献，对田口方法在经济实践中的应用进行了归纳，发现田口方法的线下质量控制包括系统设计、参数设计和容差设计三个阶段，聚焦于设计优化和工艺优化两方面，针对这两个方面总结田口方法的质量控制实践，证明田口方法具有高度适用性和优越性，是一种可以增强产品稳健性、实现低成本高效益的优化设计和工艺的方法，应用前景广泛。此外，尽管田口方法可以实现质量和效益的统一，但仍具有一定局限，需要与其他方法结合使用予以补充。

Abstract:

Based on 75 domestic and foreign Taguchi method research literatures from 1989 to 2019, the application of Taguchi method in economic practice was summarized. It was found that the Taguchi method's offline quality control included three stages: system design, parameter design and tolerance design. Focus on the two aspects of design optimization and process optimization. Summarize the quality control practice of the Taguchi method for these two aspects. It proves that the Taguchi method is highly applicable and superior. It is an optimization that can enhance the robustness of the product and achieve low cost and high efficiency. The design and process methods have wide application prospects. In addition, although the Taguchi method can achieve the unification of quality and efficiency, it still has certain limitations and needs to be supplemented in combination with other methods.
