代步汽车摘  要：
多品种小批量混流生产能够快速、灵活地组织生产特定的产品，从而响应市场日益变化的不同需求。这种新的生产模式已被越来越多的大型汽车制造企业所采用，但与之相关的投产排序问题也日益成为研究的热点。
本文概述了国内外轿车混流生产的应用状况及混流装配线的投产排序优化对于提高企业生产效率的重大意义，介绍了该课题在国内外研究状况及能用于解决该课题的遗传算法的基本原理和运行步骤。通过研究“柳州裕信方盛”实行的多品种混流生产方式，发现优化投产顺序可以降低目前存在于不同装配工位工作负荷不均衡导致暗灯停线频率的现象。这种现象因混流装配线上不同产品所需的装配工艺和装配时间不同而难以避免，并造成一定的浪费。本文以工作负荷均衡化为投产排序目标建立了数学模型，并运用遗传算法对该数学模型进行解算。
本文按上述遗传算法编写MATLAB程序，通过算实例验证了该算法和MATLAB程序的可行性。结合“柳州裕信方盛”三课汽车内饰件装配车间的应用实例的研究，通过对混流生产线上的车型进行排序，在理论上验证了该投产排序方法能有效降低制造成本，为企业带来收益。最后在总结全文的基础上，提出了对多品种混流生产调度系统的展望。

Abstract
Many kinds of small batch mixed flow production can fast flexibility to organize production of specific products, response to changing market needs. This new production model has been more and more large car manufacturing enterprise used, But the related production scheduling problems are also increasingly become the research focus.
This paper summarizes the domestic and foreign cars mixed flow production application status and mixed flow assembly line production of the sort to improve production efficiency optimization of the great significance, introduces the domestic and foreign research status and project can be used to solve this topic, the basic principle of genetic algorithms and operation procedures. Through the study of a “YuXin FangCheng LiuZhou” margin of mixed flow mode of production, find optimization can reduce production order at present are found in different assembly location imbalance working load in dark light stop line frequency phenomenon. This phenomenon for mixed flow on th
e assembly line for different product assembly process and assembly time different and hard to avoid, and cause certain waste. This paper work load equilibrium production in order to target a mathematical model is set up,and the use of genetic algorithms in the mathematical model for calculating.
This paper according to the above writing MATLAB genetic algorithm,through the calculation examples show that the proposed algorithm is and the feasibility of MATLAB. Liuzhou margin FangCheng letter with three class car inner decoration assembly workshop examples of application of research, through to the mixed flow line type of order, in theory to prove the production scheduling method can effectively reduce the production cost, for enterprise to bring in revenue last on the basis of summing up,proposed to the many kinds of mixed flow production scheduling system outlook
