    Abstract: Disclosed are modularized garment manufacturing method and system for small quantity batch production of garments. Basic components constituting an ordered garment are generated by analyzing shape graphic data of the ordered garment. For each basic component, basic patterns are generated for each dimension of the ordered garment. The basic patterns are compared with reference garment patterns stored in a garment pattern database to determine a pattern category of each basic pattern. Based on the pattern category of the basic patterns and information on garment production lines currently in operation, subdivided work modules are determined for each basic pattern.
