摘　　要：产品价格既是制造销售商与用户双方利益平衡的反映,也是双方对产品性能、质量的综合认识,可以直接用于度量产品上市后给社会带来的损失.基于此观点,提出了一种分段线性质量损失模型(以下简称为价格模型).以某型号微电机的铁芯外径为例,深入探讨该模型中的重要参数对铁芯质量损失的影响,并通过与田口质量损失模型对比分析,得出价格模型比田口模型更加符合实际.该模型为产品的公差优化设计提供了条件,丰富了质量损失领域的内容.The product price is the combination of a reflection of interest balance and a comprehensive understanding of product performance and quality between manufacturing vendors and users, which can be used directly to measure the loss that brought to society after entering the market. Therefore, a piecewise linear quality loss model （hereinafter referred to as the price model） was developed. The outer diameter of the iron core were taken in micro - motor as an example to explore the influence of the important parameters in the model on iron core quality loss, and to contrast with Taguchi quality loss model. The results show that the price model is more realistic than Taguchi quality loss model. The new price model provides the condition for product tolerance optimization design, and enriches the content of the field of quality loss.
