[Abstract]:With the globalization of market economy and the increasing demand of consumers, enterprises must respond to the market demand with the fastest speed and meet the personalized demand of consumers while reducing the cost and ensuring the quality. Multi-variety and small batch mixed flow mode can quickly respond to market changes, so more and more enterprises use mixed flow mode to deal with the rapidly changing market. The production organization mode of mixed flow assembly is to realize multi-variety mixed flow assembly by reasonably adjusting and optimizing the assembly line on the basis of basically not changing or less changing the current production conditions. Improve the production efficiency of enterprises and the ability to respond to the market. In this paper, taking the motorcycle assembly line as the background and the optimization of the production sequence of the motorcycle mixed flow assembly line as the research object, the two optimization objectives of the production sequence of the mixed flow assembly line are studied in detail. First of all, this paper introduces the background and significance of the topic, summarizes the research status of mixed current assembly line production at home and abroad, and clarifies the main research contents of the paper. Secondly, the balance of mixed flow assembly line and production sequence are studied theoretically, the relationship between assembly line balance and production sequence is analyzed, and the optimization goal of this paper is established: uniform consumption of parts and minimum production cycle; Then the uniform consumption model and the minimum production cycle minimum cycle model are established. Taking the mixed flow assembly line of motorcycle of L company as an example, according to the present situation of the assembly line of the enterprise, the model of uniform consumption and minimum production cycle of parts is established, and the uniform consumption model of parts is solved by genetic algorithm. The hybrid genetic algorithm is used to solve the minimum cyclic period minimum model. An example is given to verify that the two algorithms have certain advantages in solving both models. Finally, the minimum cycle shortest model is modeled and simulated by Witness software, and the reliability of hybrid genetic algorithm in solving the optimization problem of mixed flow assembly line production sequence is further verified, and the busy rate of workstation is analyzed. The analysis results show that the production sequence plays a decisive role in the balance problem of assembly line.
