中文摘要：
在深入分析产品平台定义及特点的基础上,结合复杂网络理论和公理设计中的信息公理,提出一种基于结构的产品平台设计方法。通过计算产品族零部件网络的节点总介数与平均介数确定节点在产品族和产品实例中的重要性,同时结合产品功能分析的结果提炼出平台关键节点。通过计算其他节点与关键节点的关联度,确定平台内的其他重要节点,并采用信息公理评价备选平台的性能,实现循环的设计过程。复杂网络与公理设计的结合使平台设计过程与结果更直观、更科学。以轮式装载机的产品平台设计为例证明了该方法良好的系统性与可操作性。
英文摘要：
Based on in-depth study of definition and characters of product platform,a structure-based product platform design method is proposed,which combines complex net theory and information axiom.It determines the importance of each node by calculating the total and average betweennesses of nodes in parts network of product family,and gets the key platform nodes with results of function analysis.Then it gets other important nodes by calculating the correlative coefficient between them and the key nodes.Using the information axiom evaluates the alternative platforms at last,and realizes the design loop.Complex net theory and axiomatic design method make this approach more clear and scientific.Taking the approach of wheel loader platform design as an example shows its systematicness and operability.
