【摘要】：近年来,整车市场需求旺盛,带动了汽车内饰部件生产企业的蓬勃发展。面对多品种小批量的需求,大多数中小汽车内饰部件企业采用按计划生产模式,由于计划生产与实际需求之间存在产品差异和时间差异,造成了在制品库存高和生产周期长的问题。JIT管理方式实现了将必要的零件以必要的数量在必要的时间送到生产线,并且只将所需要的零件、只以所需要的数量、只在正好需要的时间送到生产,从而降低在制品库存,建立起平滑而更有效的生产流程。文献显示,目前对汽车内饰部件企业的研究主要集中于产品的材料研究,尚缺乏针对汽车内饰部件生产看板系统的研究与应用。本文研究汽车内饰部件看板系统,具有一定的理论研究与推广应用价值。本文首先阐述了拉动式生产、看板以及Petri网技术在生产中应用的相关理论,以及生产系统中资源配置方法。在此基础上,以汽车内饰部件生产企业为研究对象,考虑汽车内饰部件生产过程中生产准备时间长、前后工序生产节奏差异大等因素,根据库存补充式拉动系统策略,建立了生产过程中关键看板—生产指示看板与缓冲区补货触发看板模型,提出了看板系统中的制造资源配置模型与看板关键参数的计算方法。最后,应用赋时Petri网建模方法,对汽车内饰部件生产看板系统建模,建立了各环节差异最小的平均加工时间优化模型,求解系统中缓冲区存储量与各个工序设备资源的优化配置方案,同时针对模型中资源冲突工序,提出了 Petri网看板系统资源冲突的解决方案。依据本文所设计的内饰部件拉动式管理规则,设计了看板生产信息管理原型系统,提出了生产指示看板、缓冲区补货触发看板和设备状态看板信息处理规则,提供了车间的看板布局规划,为企业实施看板信息管理系统奠定了基础。
[Abstract]:In recent years, the automobile market demand is exuberant, has driven the automobile interior decoration component production enterprise vigorous development. Facing the demand of many kinds and small quantities, most small and medium-sized automobile interior parts enterprises adopt the planned production mode, because of the product difference and the time difference between the planned production and the actual demand. The problem of high in-process inventory and long production cycle. JIT management enables the necessary parts to be delivered to the production line in the necessary quantity at the necessary time, and only the required parts, in the required quantity, are delivered to the production line, Deliver production only in time, thus reducing WIP inventory and establishing a smooth and more efficient production process. The literature shows that the current research on automobile interior parts enterprises is mainly focused on the material of products, and the research and application of Kanban system for automobile interior parts production is still lacking. This paper studies the Kanban system of automobile interior parts, which has certain theoretical research and popularizing application value. In this paper, the related theories of the application of pull production, Kanban and Petri net technology in production and the method of resource allocation in production system are introduced. On this basis, taking the automobile interior parts manufacturing enterprise as the research object, considering the factors such as the long production preparation time in the production process of the automobile interior decoration parts and the large difference in the production rhythm before and after the production process, and according to the strategy of the inventory supplementary pull system, The production indicator Kanban and buffer restocking trigger Kanban model are established in the production process. The manufacturing resource allocation model and the calculation method of the key parameters of the Kanban system are put forward. Finally, using timed Petri net modeling method, the Kanban system of automobile interior parts production is modeled, and the average processing time optimization model with minimum difference of each link is established. The optimal allocation scheme of buffer storage and equipment resources in each process is solved. At the same time, a solution to resource conflict of Kanban system based on Petri net is proposed for the resource conflict process in the model. According to the pull management rules of interior parts designed in this paper, the prototype system of Kanban production information management is designed, and the production indication Kanban, buffer restocking trigger Kanban and equipment status Kanban information processing rules are put forward. Provides the workshop Kanban layout planning, for enterprises to implement Kanban information management system laid the foundation.
