1. Multispeed drive hub is as the example to verify the application of fuzzy theory in product modular design.2. The algorithms of fuzzy interpretive structural model (FISM) and fuzzy clustering analysis (FCA) are proposed for the planning of ponents in product.3. the relationship between the assessed values of parts indicates the strength of connection in ponents.Keywords: Interpretive Structural Model, Fuzzy Synthesized Evaluation, Fuzzy Clustering Analysis, Fuzzy Sorting2 / 2
