[Abstract]:The aluminum alloy door and window mixed flow production line belongs to the typical multi-variety small batch mixed production mode. With the increase of raw material and manpower cost and customer's individualized demand, the competition pressure of door and window manufacturing industry is increasing constantly, so it is necessary to seek new development. Reasonable allocation of production resources and effective scheduling to solve the problems in production and ensure the efficient operation of mixed production of aluminum alloy doors and windows has become the primary problem of aluminum window and door production enterprises. This paper focuses on a mixed flow production system of aluminum alloy doors and windows, and models and simulates the production line of the workshop with the help of digital factory simulation technology. The balance optimization of the production line and the sequence optimization of the mixed flow are studied emphatically, which is of great significance to improve the comprehensive performance of the mixed flow production line of aluminum alloy doors and windows. On the basis of the actual investigation, this paper firstly analyzes the production of aluminum alloy doors and windows, and summarizes the connotation and key technology of the digital factory used in the production of aluminum alloy doors and windows. According to the structure and characteristics of mixed flow production system for aluminum alloy doors and windows, a unique simulation framework is proposed. Then, based on the analysis of the mixed flow production of aluminum alloy doors and windows, this paper introduces the simulation objectives, modeling principles and assumptions, data collection and processing. The simulation model of mixed flow production system of aluminum alloy doors and windows is established by em-plant, and the process of modeling is described in detail. After the simulation model is verified, through the design of simulation experiment, the balance analysis of production line, the comparative analysis of operation mode, the bottleneck analysis and improvement, and the optimization of logistics delivery system are carried out to improve the performance of the production line synthetically. Finally, the production sequence problem and optimization goal of mixed flow production line are determined, GA tools are imported into em-plant and genetic algorithm is set up. The optimal solution based on the total completion time, the average idle time rate of each station and the maximum number of in-process products is obtained. In this paper, the simulation and optimization of the mixed production line of aluminum alloy doors and windows are carried out based on the digital factory, and the optimization work is carried out, which has a good effect on improving the performance of the production system.
