Abstract: Green remanufacturing is a key technology to support the recycling economy,and product modularization can effectively promote remanufacturing and improve product reusability.For product modularization of green remanufacturing,an approach to product modularity based on transmission network model of failure modes for remanufacturing was proposed.The failure mode of product parts was analyzed,and the transmission network model of failure mode-recycling mode was constructed.The fuzzy relation matrix between different levels was constructed by using fuzzy set theory,and the recycling mode of each part was analyzed through layer by layer mapping.The comprehensive relationships between components with function,structure as well as remanufacturing indexes were analyzed,which considered the information incompleteness and fuzziness of remanufacturability index at the end of product life,and the comprehensive correlation matrix was constructed.Based on the relationship between components with function and structure,the different clustering schemes were acquired by clustering algorithm based on transitive closure,and then the hierarchical structure of product modularity was built.The Minimum Description Length (MDL) degree of module independence and remanufacturing,were introduced to realize the reasonable division of modules.A case of permanent magnet retarder starter was provided to illustrate the analysis process on the proposed method.

Key words: product modularization, failure mode, transmission network model, hierarchical structure, remanufacturing

摘要： 绿色再制造是支持再循环经济的关键技术,而产品模块化可以有效促进再制造,提高产品再利用性。针对绿色再制造的产品模块化问题,提出一种基于失效模式传递网络模型的产品模块化方法。分析产品零部件失效模式,构建了失效模式—循环再利用方式传递网络模型,应用模糊集合理论构造不同层次之间的模糊关系矩阵,通过逐层映射以判析各零部件的循环再利用方式。综合分析零部件间功能—结构的关联关系及再制造特性的关联关系,考虑到产品寿命终结阶段再制造性指标的信息不完整性和模糊性,建立了综合关联矩阵。以零部件功能和结构的关联关系为聚类基础,基于传递闭包的聚类算法,获得不同的零部件聚类方案,建立产品模块化层次结构,以模块独立性和再制造性的最小描述长度为准则,实现模块的合理划分。以永磁减速起动机为例,验证了所提方法的有效性。
