摘要
针对质量屋(HOQ)矩阵维数大、工程上不便处理的问题,提出了一种基于HOQ矩阵的产品模块两阶段分解方法.首先根据产品工程性能互相关矩阵,按照最大-最小划分方法,通过求解Fiedler特征值以及相应的Fiedler特征向量的方法,将产品工程性能进行分组,然后根据用户需求与产品工程特性的关系矩阵以及按工程性能分组所确定的分组数,按照惟一及最大相关度的原则通过求解0-1优化问题,将用户需求分配到相应的组中,从而将具有强耦合的用户需求与产品工程性能紧密相连,实现了对产品模块的划分.通过对某机床设计的实例,验证了该方法对于产品模块化设计的有效性.
A two-step modular cluster method for products based on house of quality(HOQ) matrix was proposed to solve the difficulties of extremely vast matrix dimensions in engineering fields. According to engineering performance(EP) correlation matrix, the EPs were first clustered via solving the Fiedler eigenvalue and the corresponding eigenvector with min-max cut algorithm. Considered the relation matrix of customer requirements(CRs) and EPs and solved a 0-1 optimal problem, the CRs were then clustered with the EPs determined group number, which confirmed the unique and maximum relation criterions; thus the tight coupling customer requirements and engineering performance were clustered into modules. A machine tool case verifies the effectiveness of the proposed approach for modularizing product design.
