After thoroughly researching and investigating automobile assembly process , this thesis plans and detailedly designs an automobile type and logistics information publication system , develops an assembly process and logistics publication system based on network . related theory and technology are mentioned in the paper as well 本论文在对汽车总装配生产过程进行深入研究和现场调研的基础上，规划并设计了车型及物流信息发布系统，在此基础上进一步开发了基于网络的装配工艺及物流信息发布系统，并对相关的理论和技术细节进行详细的阐述。
Aiming at the problems of the low - grade quality and low efficient in the screw thread assembly which exist in automobile assembly of china , it is expounded in this paper that the research and manufacture of the screw automatic tightening machine will accelerate the development of the chinese automobile industry greatly after the development situation of the screw tightening machine in china or in other countries is analyzed 本文针对我国汽车装配中的螺纹装配的质量和效率问题，分析了对螺纹进行自动装配的拧紧机在国内、国外的发展情况，阐述了研制螺纹自动拧紧机对我国汽车业发展的重大意义。
Like any other production line design , the design of automobile assembly - welding line focuses on two points : work - load balance and workshop layout , by aiming at reducing the cost of maintenance and operation , improving the production efficiency , and assuring the long - term operation efficiency of the line 同所有生产线系统设计一样,汽车装焊生产线优化设计的重点是解决生产线平衡和设备布局问题,其目的旨在降低维护费用和运行成本、提高设备利用率、确保生产线系统的长期高效运作。
Then , the mathematical models for workshop layout of general production line and automobile assembly - welding line are given , the topology model of multiple constraints expression and workshop layout is presented in depth , and then principles on position check and constraints check are also presented . a modified genetic algorithm is also proposed based on traditional generic algorithm 在此基础上,以物流优化和空间利用率最大化为目标,建立了车间设备布局的一般数学模型和汽车装焊车间设备布局的数学模型;深入探讨了多种约束表达和车间布局的拓扑模型,提出了约束检验的方法和位置判定的原则。
In this paper , the planning and design of an automobile assembly - welding line is conducted according to the specific requirement on production streamline and process of automobile assembly - welding production . the design is optimized centered by work - load balance and workshop layout . a small - scale automated layout software is also developed targeting at the design and optimization of automobile assembly - welding line 本文根据汽车装焊作业特定的生产流程和工艺要求进行了装焊生产线规划设计,并围绕生产线平衡问题和设备布局问题进行了设计优化,开发了相应的面向汽车装焊车间设备布局优化的小型自动布局软件系统。
