基于产品全生命周期的产品规划建模与应用

市场竞争的不断升级迫使企业将产品价值的挖掘延伸至产品的全生命周期，这为企业带来了更多的产品创新空间和盈利机会，但同时也带来了产品决策的难题。首先以设计域理论为基础建立了一个能够有效表明基于全生命周期系统化特征的产品规划建模框架，以确保产品决策能够有效地融合设计人员的产品设计理念、市场人员对产品需求的分析、生产人员对产品实现过程的分析以及售后服务人员对产品服务过程的分析；接下来，以产品进化设计为研究对象，提出了基于全生命周期的产品规划所必须依赖的决策指标体系和有效表明其权衡取舍机制的建模方法；最后通过在家用轿车产品上的应用，具体表明了方法的有效性和实用价值。提出的方法明确了企业不同的参与者在产品规划过程中需要进行信息交互的具体内容，建立了以不断完善产品信息建构体系为导向的决策机制，是一个符合企业实际需要的系统化方法。

Product Planning Decision Based on Product Life Cycles:Modeling and Application

The constant upgrading of market competition forces enterprises to extend the product value to the product life cycles (PLC). This brings about more opportunities for product innovation and benefit, while makes the product decision more difficult in the meantime. A product planning decision framework is firstly set up along the entire spectrum of PLC on the basis of the concept of design domains to reflect the systematic characteristics of the PLC and to promote the integration of the analysis on the customer needs, the design conceptions, the analysis on product realization and after-sales maintenance. Secondly, by the case of the generational design, the metrics for PLC-based decision are presented and the modeling method is explored to effectively demonstrate the trade-off mechanism. Lastly, by way of illustration, a product example of family sedan is planned and its results demonstrate the effectiveness of the modeling. The presented method sets up the decision mechanism oriented by the establishment of information connection among the different department in the company and should show its practical value by forward application.
