面向产品可持续设计的模块化划分方法

Modular Division Method for Sustainable Design of Products

目的为了实现可持续产品的快速开发,提出面向产品可持续设计的模块划分方法。方法基于功能流模型进行产品的功能分解并建立产品的功能结构,依据功能流的形式和关系实现产品功能模块的定性划分,在此基础上,基于参数流的相关性判断应用聚类分析实现模块的定量划分。将可持续性设计原则与产品生命周期特征集成,并基于设计结构矩阵的零件相关度进行面向可持续性设计的模块划分。综合2种模块划分结果,并从可持续性设计角度进行模块的合并、更替及再划分,获得最优模块划分方案。结果依据方法得到的产品模块在满足功能基础上具有可持续性,实现了对产品的可持续设计。结论该方法集成功能与全生命周期实现了产品基于可持续性的模块划分。

The work aims to propose a modular division method for product sustainable design to realize rapid development of sustainable products. The product functions were disassembled and the product function structure was established based on the function chain model. The qualitative division of function modules of the products was achieved based on the forms and the relations of function chain. On this basis, the quantitative division of modules was achieved by the clustering analysis according to the relativity judgment of parameter flow. The sustainable design principles and features of the product life cycle were integrated, and the modular division of sustainable design was conducted based on the component relevancy of design structure matrix. Combined with the two results of module division, the module was combined, replaced and redivided from the perspective of sustainable design, so as to achieve the best module division solution. The product module obtained in the proposed method has sustainability on the basis of satisfying the functions and realizes the sustainable design of products. This method integrating the function and the whole life cycle has achieved the modular division of products based on the sustainability.
