The invention relates to an optimization scheduling method for the ring spinning process in a spinning workshop, and belongs to the technical field of intelligent optimization scheduling of the production workshop. A scheduling model and an optimization target of a batch of spinning raw materials to be processed and formed in the ring spinning process are determined and the target is optimized bythe optimization scheduling method based on the improved firefly algorithm. The scheduling model is established according to the processing time of each batch of raw materials on each textile processing machine in ring spinning production, and the optimization objective is to minimize the maximum completion time. The excellent solution of the ring spinning process scheduling problem in the spinning workshop can be obtained in a relatively short time, thereby saving the production time, reducing the waste of factory production cost possibly caused by improper arrangement and improving the production efficiency and the economic benefit of the factory.
Description
technical field [0001] The invention relates to an optimal scheduling method for the production process of a ring spinning process in a spinning workshop, and belongs to the technical field of intelligent optimal scheduling of a production workshop. Background technique [0002] The textile industry is a traditional advantageous industry in my country, and it occupies a relatively large proportion in the national economy and industrial structure. With the increasingly fierce market competition in the textile industry, the awareness of energy-saving competition among enterprises is becoming stronger and stronger. And a good scheduling plan can reduce the production cost of the enterprise, improve the production efficiency, and enhance the competitive advantage of the enterprise. Therefore, it is very important for modern textile enterprises to develop efficient dispatching techniques and methods. [0003] The spinning types of textile enterprises mainly include ring spinnin...
