Abstract
The chapter provides the concepts of group technology and cellular manufacturing. Grouping objects into groups based on the object features has been done using group technology (GT) approaches. Similar components can be grouped into design families, and new designs can be created by modifying an existing component design from the same family. The philosophy of group technology is an important concept in the design of advanced integrated manufacturing systems. Group technology is not an answer to all manufacturing problems, but it is a good management technique to standardize efforts and eliminate duplication. A well-designed classification and coding system may result in several benefits for the manufacturing plant.
