【摘要】：汽车混流装配具有生产设施柔性高、工序相似、员工多技能化等特点,通过合理安排混流线上不同汽车产品的投产顺序,实现多车型共线装配,能够快速响应汽车市场的个性化需求。本文以SW汽车总装车间混流装配线研究对象,研究了混合品种装配线投产优化的关键技术。混合品种装配线投产优化的目标主要有:物料消耗平准化,品种切换时混流线总调整成本最小和最小化工作站的工作超载。物料消耗平准化指汽车混装线不同车型装配所需零件在单位时间的消耗量尽可能保持不变.本文以物料消耗速率波动最小化为目标,结合SW总装车间混流投产情况,建立了改进的投产优化数学模型,采用丰田的目标追迹算法进行了模型求解,并用Flexsim 3D软件进行了仿真验证。主要内容如下:1.介绍了国内外有关汽车混流装配投产排序方面的研究现状,并简要阐述了汽车混流装配线的概念,以及汽车混流装配的排序研究问题;2.介绍了物料消耗平准化的定义以及平准化投产的必要性,结合SW公司总装车间汽车混流装配实际情况建立了物料消耗平准化的投产优化数学模型,采用目标追迹算法对数学模型进行求解,并设计了快速求解混流装配线上不同车型投产排序的平台,实现了混流线汽车装配物料消耗的平准化。3.用Flexsim软件对汽车混流装配线进行了建模仿真,对SW公司实际投产顺序和优化的投产两种方案进行了仿真与分析,仿真结果表明优化后的投产顺序能使物流消耗更均匀,平准化程度更高。
[Abstract]:Automobile mixed assembly has the characteristics of high flexibility of production facilities, similar working procedures, multi-skilled employees, and so on. By reasonably arranging the production sequence of different automobile products on the mixed line, the collinear assembly of multiple models can be realized. Can quickly respond to the personalized demand of the automobile market. In this paper, the research object of hybrid assembly line in SW automobile assembly shop is studied, and the key technology for optimization of hybrid assembly line is studied. The objectives of optimization of hybrid assembly line are as follows: material consumption leveling, total adjusting cost of mixed flow line minimized and workstation overloading minimized. Material consumption equalization means that the consumption of parts per unit time of different vehicle assembly line is as constant as possible. In this paper, with the aim of minimizing the fluctuation of material consumption rate, an improved optimization mathematical model is established, which is based on the mixed flow of SW assembly shop, and the model is solved by using Toyota's target tracing algorithm. The simulation is carried out with Flexsim 3D software. The main content is as follows: 1. This paper introduces the research status quo of automobile mixed flow assembly and commissioning scheduling at home and abroad, and briefly expounds the concept of automobile mixed flow assembly line and the research problem of vehicle mixed flow assembly sequencing. This paper introduces the definition of material consumption leveling and the necessity of leveling production. Combined with the actual situation of automobile mixed flow assembly in the assembly shop of SW Company, the optimization mathematical model of material consumption leveling is established. The mathematical model is solved by using the target tracing algorithm, and a platform is designed to quickly solve the sequencing of different vehicle models on the mixed flow assembly line, which realizes the leveling of material consumption of hybrid line automobile assembly. 3. The vehicle mixed flow assembly line is modeled and simulated with Flexsim software. The simulation and analysis of the actual commissioning sequence and the optimized commissioning scheme of SW Company are carried out. The simulation results show that the optimized commissioning sequence can make the logistics consumption more uniform. The level of equalization is higher.
