【摘要】：推土机作为一种工程车辆,在道路工程、水利工程、环保工程等建设中起着不可或缺的作用。随着“十二五”计划的出台,工程机械迎来了前所未有的发展机遇,但我国推土机生产制造技术明显落后于发达国家,由于推土机生产具有加工要求高、难度大、生产周期长、投资大等特点,这些特点为企业优化生产系统带来了很大的困难。计算机仿真可以大大缩短开发时间、节约成本,采用仿真技术对生产线进行规划设计成为推土机制造企业的优先选择的手段。生产线仿真技术是目前制造业广泛采用的先进技术之一,它以计算机仿真技术为基础,通过软件中的模型模拟现实中的生产制造过程,实现对生产系统运行状况的预测,从而发现生产过程中的瓶颈问题,帮助决策者发现问题、解决问题,实现生产效率的提高。本文首先阐述了制造物流系统的定义以及离散事件系统仿真的相关理论知识,同时介绍了本文所涉及的乐龙物流仿真软件Ra LC;其次,对生产线基本概念和生产线平衡的重要性进行了详细的研究,列举了制造业制造物流系统几种常见的评价指标;第三,详细地分析了企业新厂的总体规划和推土机联合车间制造物流系统要求及相关信息;第四,结合生产线工艺流程,利用Ra LC建立推土机联合车间制造物流系统的仿真分析模型;最后,基于生产线平衡理论,对模型进行仿真分析,确定生产系统中的瓶颈问题,利用现代物流技术和先进的物流手段,提出优化措施,将优化措施纳入仿真模型中重新分析,验证优化措施的可行性。本文通过设计一个应用现代物流方式的制造物流系统,旨在满足企业新厂效率高、成本低和安全性高的目的,具有一定的实际意义和理论价值。
[Abstract]:As a kind of engineering vehicle, bulldozer plays an indispensable role in the construction of road engineering, water conservancy project, environmental protection project and so on. With the introduction of the 12th Five-Year Plan, construction machinery has ushered in unprecedented opportunities for development. However, the production and manufacturing technology of bulldozer in our country lags behind that in developed countries obviously. Because of the characteristics of bulldozer production with high processing requirements, great difficulty, long production cycle and large investment, etc. These characteristics bring great difficulties to the optimization of production system. Computer simulation can greatly shorten the development time and save the cost. Planning and design of production line by simulation technology has become the first choice means for bulldozer manufacturing enterprises. Production line simulation technology is one of the advanced technologies widely used in manufacturing industry at present, and it is based on computer simulation technology. The model in the software simulates the production manufacturing process in reality, realizes the forecast to the production system running condition, thus discovers the bottleneck problem in the production process, helps the decision maker to discover the problem, solves the problem. In this paper, the definition of manufacturing logistics system and the relevant theoretical knowledge of discrete event system simulation are introduced. At the same time, the Lulong logistics simulation software Ra LC. which is involved in this paper, is introduced. The basic concept of production line and the importance of production line balance are studied in detail, and several common evaluation indexes of manufacturing logistics system are listed. The general plan of the new factory and the requirements and relevant information of the manufacturing logistics system in the bulldozer joint workshop are analyzed in detail. 4th, the simulation analysis model of the manufacturing logistics system of the bulldozer joint workshop is established by using Ra LC combined with the production line process. Finally, based on the balance theory of production line, the model is simulated and analyzed, the bottleneck problem in production system is determined, the optimization measures are put forward by using modern logistics technology and advanced logistics means, and the optimization measures are reanalyzed in the simulation model. To verify the feasibility of optimization measures, this paper designs a manufacturing logistics system using modern logistics mode, which aims to meet the purpose of high efficiency, low cost and high safety of new plant, which has certain practical and theoretical value.
