Abstract

The invention discloses a cutting and bed separating method based on a double-population hybrid algorithm. The cutting and bed separating method is specifically implemented according to the following steps: 1, initializing the algorithm; 2, determining a target function of a cutting and bed separation scheme, setting targets on multiple dimensions, and performing processing to obtain a target function of a final algorithm; 3, according to the maximum value interval and the minimum value interval, obtained in the step 1, of the number of the cutting beds and the objective function, obtained in the step 2, of the model, selecting the minimum number M of the cutting beds, and carrying out initialization of a hybrid algorithm; 4, evolving a common population in the hybrid algorithm; 5, carrying out elite population evolution; 6, comparing the final superiority of the optimal scheme under a plurality of cutting beds; and 7, finally outputting one or more groups of excellent cutting and bed separation schemes according to specified cutting and bed separation requirements and targets.

Description

technical field [0001] The invention belongs to the technical field of computer-aided garment cutting and bed separation, and relates to a cutting and bed separation method based on a double-population mixing algorithm. Background technique [0002] The formulation of the cutting and dividing bed plan is a difficult problem faced by all garment manufacturers, and it is also the core issue of the entire production process. The production of clothing has the characteristics of short delivery time, multiple styles and sizes, and small and medium batches, so an excellent cutting and dividing bed plan is especially important. important. Only by formulating a suitable cutting and splitting plan can the high efficiency and low cost requirements of enterprise production be met. The greater the profit in the order production of the enterprise, the stronger the competitiveness in the industry will be. [0003] In the traditional garment production, when formulating the cutting and di...
