Group Technology is a method of increasing the productivity for manufacturing high quality products and improving
the flexibility of manufacturing systems in the many variety and small batch production. The parts with the same or
similar process route are gathered into a group through production flow analysis. Each part processing route was
analyzed. The production flow analysis figure of the parts was drawn. The fuzzy clustering algorithm was used to
classify the machine tools and the parts. The fuzzy similar matrices and the relay closure matrices were obtained based
on MATLAB. Then the corresponding relations between each group of the parts and each group of the machine tools
were found. The similar parts were gathered and the workshop machine layout was reconstructed. The steps of
production flow analysis and the fuzzy clustering analysis were introduced. The effectiveness of the method was proved
by an example.
