Abstract: This paper used the artificial nerve network to research the design of suit pattern.Take the specifications and sizes of the finished suits as the input parameters,while the sizes of the detailed parts as the output parameter,then train the nerve network point by point to approach their nonlinear mapping relation.Here,the approaching function of arbitrary function of the nerve network is used to obtain the approximate function relation,and establishes the BP nerve network model for suit pattern design.The simulation results indicated that the research affords the theory and technology referrence for the realization of 2-D patterns produced automatically for the garment styles and that of intelligent garment production.It is a new attempt to associate the apparel science with the information processing science,which will bring new vitality to the research of apparel production technology.
