Abstract

A method of garment cutting bed splitting based on trial-and-error particle swarm optimization is proposed. Based on the relatively fixed short interval integer matching problem, the trial-and-error method is used to quickly select the optimal matching ratio, and then combined with particle swarm optimization algorithm, the ideal combination scheme of cutting layers and nesting ratio can be obtained quickly. The hybrid algorithm makes use of the fast convergence of particle swarm optimization algorithm to enhance the global convergence of the algorithm and converge to the global optimal solution of the standard particle swarm optimization algorithm. Then the least square method is used to optimize the global optimal solution to reduce the experimental error, and then the optimal parametercombination in the garment cutting bed-splitting method can be obtained quickly. The invention provides an intelligent garment cutting bed splitting method capable of realizing quick bed splitting, effectively improving precision and effectively processing different garment orders.

Description

technical field [0001] The invention belongs to the technical field of computer-aided clothing bed separation, and in particular relates to a clothing cutting and bed separation method based on a trial and error particle swarm algorithm. Background technique [0002] The garment industry is one of the traditional pillar industries of our country and plays an important role in the national economy. In recent years, the increase in labor costs has made clothing production more and more expensive. At the same time, the personalization trend of clothing development has caused the problem of increasing the size of clothing orders, which puts forward higher requirements for the design of production plans. As the first process of garment production, cutting directly affects the quality and cost of garment products, and then affects the overall economic benefits of the enterprise. Therefore, how to optimize distribution to reduce the number of separate beds and cutting errors, the...
