面向产品生命周期的BOM相似性度量方法

为满足大规模定制、单元制造等制造模式下产品族划分的需求,全面分析了BOM在产品生命周期中的相似特征,提出基于相似系统论的面向产品生命周期的BOM相似性度量(PL BSM)方法.给出包含组成元素、相似元和相似特征及其权重的面向产品生命周期的BOM相似度计算公式,提出广度优先遍历有序树的相似性度量算法,并给出可扩展相似性计算框架,构成完整的PL BSM方法.以实例说明PL BSM方法能以全局优化的方式给出可靠的计算结果,提高产品族划分的效率和质量.

Product Lifecycle-oriented BOM Similarity Metric Method

To meet the requirements of grouping product families for advanced manufacturing paradigm such as mass customization,product lifecycle-oriented
BOM similarity metric (PL BSM) method was presented based on similarity system theory through comprehensively analyzing similar properties of BOM in lifecycle. Firstly an all
weighting formula was proposed,whose factors consisted of constituent element,similar unit,similar property and their weights.Then an algorithm based on ordered tree breadth-first search and an extensible calculation framework were presented.The formula, algorithm and framework consisted of the complete PL BSM method.At last,an application instance is shown to confirm that PL BSM can get reliable result by global optimization calculation,and improve the efficiency and quality of grouping product families.
