服装行业产品全生命周期需求流动链知识表达

 为了满足服装产品的客户需求，提出基于服装行业的产品全生命周期（PLM）需求流动链知识表达方法。采用系统化的知识表达方法描述其协同知识结构，分析PLM需求流动链协同知识表达的形成过程，并应用语义方法表达整个需求流动链上的协同知识。最后，开发服装产品的PLM需求流动链协同知识表达的原型系统――KESFCRFN，研究该系统的体系结构、建模技术和运行过程。结果表明，PLM需求流动链内应用知识表达方法描述需求协同，优化了系统实施的需求结构资源，提高了服装企业的竞争力。

Knowledge representation of product lifecycle management demand flow chain in garment sector

In order to meet customer demand on costime, The knowledge representation on coordination facing product lifecycle management demand flow chain based on costume enterprise is put forword. The forming of cooperating knowledge is analysed in PLM demand flow chain,and the cooperation knowledge is expressed in the whole demand flow chain through knowledge semantic. Finally, the prototype system of Cooperation Knowledge Representation System facing Requirement Flow Chain is developed. The system architecture, modeling technology and peration process is studied.The result objectively reveals that the study theory realises the knowledge management on cooperation mechanisms in PLM demand flow chain effectively,which improves the competence of costume enterprise.
