为了在产品设计开发过程中能有效地预防和控制设计缺陷,对设计缺陷因素进行了总结并根据设计缺陷因素的属性和对设计缺陷影响性质和方式的差异对其进行了分类；根据硬件产品设计开发过程,定性地分析了设计缺陷因素对设计过程的影响.以此为基础,构建了硬件产品设计缺陷因素与设计缺陷类型的关系网模型；运用logistic回归理论,建立了硬件产品设计缺陷因素的回归分析模型,实现了设计缺陷因素对设计缺陷影响的定量化分析.研究成果也为进一步深入研究设计缺陷的形成机理做了有益的尝试.%In order to prevent and control the defects of design effectively in the product design process, the factors affected the defect in design were classified according to the differences in the nature and manner of design defects. According to the hardware product design process, the effect of design factors on the design process has been analyzed qualitatively. Meanwhile, the relation web model that the types of hardware design defects as a function of the factors affecting design defects was established. The method of logistic regression was used to build the regression analysis of the factors affecting design defects. On this way, it Makes the quantitative analysis of defect factors of design flaws become possible. Those conclusions are also useful for the further studying on the formation mechanism of the hardware design defects.
