Reachable Matrix and Directed Graph - Based Identification Algorithm of Module Change Propagation Path for Product Family

摘要

Product family design is the core of mass customization and has been identified as an effective tool to quickly respond to the customers' demands, and achieve the proliferation of product variants by diverse market niches. There are often coupling dependence relationships between modules, which will increase the difficulty of product design. For this reason, an identification algorithm of change propagation path for modular product family. Instigating component and affected component between association modules are determined, and the latter is regarded as feeding component inside the module. Applying reachable matrix, the target components influenced by affected component can be confirmed. Then the directed graph combined, the search process of change propagation path is presented.
