中文摘要：

作为产品族规划或再设计的关键环节,通用性决策有效缓解产品系列繁殖的负面效应,成为企业资源整合的重要手段。通过研究产品族通用性相关文献,回顾了产品族通用性的基本概念并分析了通用性决策在产品族设计中的关键作用;基于通用性决策过程,着重从零部件层次、正反两个方面论述了通用性对产品族全生命周期各阶段成本的影响,总结了基于产品族体系结构的通用性评价指标和面向参数化产品族的通用性评价指标,分析了通用性与产品性能、通用性与市场绩效之间的权衡模型及其应用;最后讨论了目前研究中的不足之处并指出了产品族通用性的未来研究方向。

英文摘要：

As a key link in product family/platform planning or redesign,commonality decision effectively alleviates the negative effects of product line propagation,leading to an important measure in enterprise resources integration. Via analysis of pertinent literatures on product family commonality,basic concepts were reviewed and the pivotal role of commonality decision in product family design was demonstrated firstly. Then,based on the process of commonality decision,impacts of commonality on costs at each stage of the whole lifecycle were discussed from component level and both positive and negative aspects,evaluation indexes both based on the product family architecture and for parametric product family were summarized,tradeoff models between commonality and product performance and between commonality and market performance were examined in detail. Finally,deficiencies in recent researches were pointed out and future research directions were discussed.
