关键的产品规划阶段，在产品开发周期的早期，需要一个设计工具来确定工程优先级，选择首选的设计概念，并在考虑消费者和生产者的需求的同时设定工程性能的目标水平。将质量功能展开（QFD）方法作为一种设计过程工具，将顾客需求转化为工程特性；然而，在产品计划中使用QFD方法的局限性已经被确定。本文基于基于决策的设计（DBD）原则，提出了一种新的设计工具——产品属性功能部署（PAFD），作为一种决策理论的企业级过程工具，用于指导概念设计阶段。PAFD方法在利用DBD的定量决策过程的同时，扩展了QFD的定性矩阵原理。PAFD方法建立在工程、市场营销和决策分析中已建立的方法的基础上，以消除QFD方法中对性能、优先级和属性耦合的用户评级和排名的需要。比较了QFD和PAFD方法的差异，并以汽车歧管绝对压力传感器的概念设计为例，说明了PAFD方法的特点和优点。
The critical product planning phase, early in the product development cycle, requires a design tool to establish engineering priorities, select the preferred design concept, and set target levels of engineering performance while considering the needs of both the consumer and producer. The quality function deployment (QFD) method was developed as a design process tool to translate customer needs into engineering characteristics; however, limitations have been identified in using the QFD method for product planning. In this paper, a new design tool called product attribute function deployment (PAFD), based on the principles of decision-based design (DBD), is introduced as a decision-theoretic, enterprise-level process tool to guide the conceptual design phase. The PAFD method extends the qualitative matrix principles of QFD while utilizing the quantitative decision-making processes of DBD. The PAFD method is built upon established methods in engineering, marketing, and decision analysis to eliminate the need for the user ratings and rankings of performance, priority, and attribute coupling in the QFD method. The differences between the QFD and the PAFD processes are compared and contrasted, and the conceptual design of an automotive manifold absolute pressure sensor is used as a case study to demonstrate the features and benefits of the PAFD method.
