ABSTRACT For the coupling between modules in product family design, an approach to analysing coupled design for product family based on coupling incidence path and correlation impact degree is presented. The coupling of three cases is discussed, i.e. the coupling between platform modules, between platform module and customisation module, as well as between customisation modules. Then the interface among modules can be identified, and instigating components are considered as controllable factors and experimental design techniques are utilised to analyse their influence on the design objectives. According to analysis on coupling incidence path and correlation impact degree, the implementation sequence of modules is identified and corresponding decoupling strategies are proposed, if any, that may weaken the coupling of product family design. Finally, an example on the trolley design of gantry crane is provided to illustrate the proposed method for coupling analysis and decoupling of association modules in product family design.

一种产品族设计中关联模块的耦合分析方法

摘要 针对产品族设计中模块间的耦合问题，提出了一种基于耦合发生路径和相关影响度的产品族耦合设计分析方法。讨论了三种情况的耦合，即平台模块之间的耦合，平台模块与定制模块之间的耦合，以及定制模块之间的耦合。然后可以识别模块之间的接口，并将激励组件视为可控因素，并利用实验设计技术来分析它们对设计目标的影响。根据耦合发生路径和相关影响程度的分析，确定模块的实现顺序，并提出相应的解耦策略，如果有的话，可能会削弱产品系列设计的耦合。最后，
