Embodiment 1

[0051] Embodiment 1: as Figure 1-5 As shown, an optimal scheduling method for the tobacco shredded processing process, by determining the tobacco shredded process scheduling model and optimization goals in the factory, and using the optimized scheduling method based on the improved chaotic fireworks algorithm to optimize the goals; among them, the scheduling The model is established based on the maximum completion time of processed tobacco raw materials on each processing equipment, and the optimization goal is to minimize the maximum completion time C max (π):

[0052] C max (π)=C π(n),m

[0053] C π(i),j =max{C π(i-1),j ,C π(i),j-1}+p π(i),j

[0054] C π(1),j =C π(1),j-1 +p π(1),j

[0055] C π(i),1 =C π(i-1),1 +p π(i),1

[0056] C π(1),1 =p π(1),1

[0057]

[0058]

[0059] In the formula, the number of tobacco raw materials is n, and there are m machines in total. A solution to this optimal scheduling problem is π={π(1),π(2),K,π(n)}; O i,j Indicat...

Abstract

The invention relates to an optimization scheduling method of a tobacco shredding process, belonging to the technical field of intelligent optimization scheduling of a production workshop. The invention determines the tobacco shredding process scheduling model and the optimization target in the factory, and optimizes the target by using the optimization scheduling method based on the improved chaotic fireworks algorithm. The scheduling model is established according to the maximum completion time of tobacco raw materials processed on each piece of processing equipment, and the optimization objective is to minimize the maximum completion time. The invention can obtain an excellent solution to the tobacco silk processing process scheduling problem in a short time, thereby reducing the production cost of the factory, improving the production efficiency of the factory, enhancing the competitiveness of the enterprise, and effectively solving the problems of waste of the factory cost and loweconomic benefit caused by improper processing sequence in the tobacco silk processing process.

Description

technical field [0001] The invention relates to an optimal scheduling method for tobacco shredded processing, and belongs to the technical field of intelligent optimal scheduling of production workshops. Background technique [0002] In recent years, the competition in the industry among different tobacco industry companies and the restrictions of national programs have made the tobacco industry more and more competitive. For this reason, all enterprises urgently need to improve their competitiveness in the tobacco industry. Production planning and production job scheduling are undoubtedly the key to production organization and management, and are of great significance to improving the production efficiency and capacity utilization rate of enterprises and reducing production costs. In the tobacco production process, the silk production process is a very important link. It is a process in which tobacco leaves are made into qualified shredded tobacco through various processin...
