本文件通过稳健的参数设计为QFD相关的优化方法提供指导，以确保客户对新产品、服务和信息系统的满意度。它适用于在产品设计阶段，基于对其功能鲁棒性的评估，确定设计参数的最佳标称值。 注:本文件中描述的一些活动可在早期和后期使用。附件B列出了解决新技术和产品开发过程中优化问题的其他方法。

This document provides guidance for QFD-related approaches to optimization through robust parameter design to ensure customer satisfaction with new products, services, and information systems. It is applicable to identify optimum nominal values of design parameters based on the assessment of robustness of its function at the product design phase. NOTE Some of the activities described in this document can be used at earlier and later stages. Other approaches to solve optimization problems in new technology and product development processes are listed in Annex B.
