基于KBOM的BOM工程变更研究

为了对产品族中的BOM变更进行有效管理,通过对产品生命周期中的BOM演进的研究,揭示了以KBOM为知识源的BOM视图演进规律,深入剖析了KBOM的知识内涵,进而研究了基于KBOM的BOM工程变更物理模型,揭示了变更请求、评估、实施、传播等变更环节间的内在联系,给出了变更影响分析和评估模型,给出了变更实施、传播实现策略,以此为基础建立了BOM结构工程变更信息模型,开发了相应的软件模块,通过软件后期的实施应用,验证了文中所述方法的可行性和有效性。

Study of BOM Engineering Change Based on KBOM

To effectively manage BOM Engineering Change(BOMEC) of product family, the internal relations among BOM views which regarded as knowledge source was revealed by study of the rule of BOM evolution in the product 1ife cycle, knowledge connotation of KBOM was analyzed. Then by detailed researching on the physical model of BOM engineering change based on KBOM, the internal relations among BOM engineering change processes which included request, evaluation,implementation and propagation were revealed. The change impacts analysis and evaluation model was presented, the realization strategy of implementation and propagation was given. Based on it, the information model for BOM engineering change was constructed, and the software module for BOM engineering change was developed. The practical application showed the system was efficient and feasible
