产品寿命周期工程设计是绿色产品设计的有效方法。本文在深入分析产品寿命周期全过程的基础上 ,提出了LCED的三大设计原则 ,详细描述了LCED的设计过程。通过举例详细阐述了应用公理性设计方法对寿命周期中有关技术先进性、环境协调性 ,以及经济性等信息进行处理的方法 ,并作出设计决策。 Product life cycle engineering is an effective method of green product design. Based on the thorough analysis of the whole process of product life cycle, this paper presents three major design principles of LCED and describes the design process of LCED in detail. By way of example, this paper elaborates the method of using axiomatic design method to deal with the information such as technology advancement, environment coordination and economy in life cycle, and makes the design decision.
