【摘要】：随着中国制造业的崛起与快速发展,企业生产组织方式面临着新的挑战和机遇,客户需求逐渐增多,产品生命周期不断缩短,传统的备货式生产因不能快速响应市场环境和需求而逐渐被新的生产方式所代替:面向客户订单、多品种、中小批量、交货期短、行业竞争、利润空间缩小等,又给制造类型企业造成了转型的压力。如何加快研发能力,缩短生产周期,降低生产成本并在同行业竞争中胜出,成为企业亟需解决的问题。PCB生产行业体现出典型的按单制造(Make to order,MTO)特点,每日接单能力与订单品种数甚至成为了企业产能的衡量标准,如何加强工程研发与加快制造周期,实现快速交货,是企业生存的关键。本文以广州某PCB生产企业为研究对象,结合负荷控制的理论思想,重点关注企业的订单管理规则、订单业务流程改善以及生产计划与控制系统的建设规划三个问题。全面梳理订单管理规则、各设备资源组产能约束,以面向负荷的生产计划与控制原理,建立围绕瓶颈工序负荷评估的订单接收与投放体系,并在此基础上,根据负荷控制闭环反馈的特点,找到平衡各种订单大类混流路径规划与最大化利润的支点。本文以PCB企业实际案例为背景,提出了PCB行业以生产计划与控制思想指导订单接收与投放各项业务流程的方法,最后通过系统建模仿真方式验证以下几个问题:1,不同的负荷控制水平(关键工序订单结存量)及相应的订单规则环境下,车间制造提前期统计规律;2,急单接收能力/急件控制规则与交期保障能力分析实验;3,混流模式下各关键工艺路径负荷上限的设定。最后通过仿真结果,指导实施过程的各项关键变量,缩短制造周期,提升产能,快速应对内外环境变化,提升市场竞争力,为企业盈利水平的提升和生产组织方式与计划控制策略奠定良好基础。
[Abstract]:With the rise and rapid development of Chinese manufacturing industry, the enterprise production organization is facing new challenges and opportunities, customer demand is increasing gradually, the product life cycle is continuously shortened. The traditional stock-ready production has been replaced by the new production mode because of its inability to respond to the market environment and demand quickly: customer oriented order, multi-variety, medium and small batch, short delivery time, industry competition, shrinking profit space, etc. How to speed up R & D capabilities, shorten production cycle, reduce production costs and win in the same industry competition, PCB manufacturing industry embodies the typical characteristics of making order to order MTO. The ability to receive orders daily and the number of orders have even become the measurement standard of enterprise capacity. How to strengthen the engineering research and development and accelerate the manufacturing cycle, Fast delivery is the key to the survival of the enterprise. This paper takes a PCB production enterprise in Guangzhou as the research object, combining with the theory of load control, focuses on the order management rules of the enterprise. Order business process improvement and production planning and control system construction planning. The order management rules, capacity constraints of each equipment resource group, to load oriented production planning and control principle, The order receiving and delivery system around the bottleneck process load evaluation is established, and based on this, according to the characteristics of closed loop feedback of load control, To find the fulcrum of balancing the mixed flow path planning and profit maximization of various order types. Based on the actual case of PCB enterprise, this paper puts forward a method for PCB industry to use the idea of production planning and control to guide orders to receive and put in various business processes. Finally, the system modeling and simulation method is used to verify the following several questions: 1, different load control levels (order aggregate stock in key processes) and corresponding order rules. The statistical rule of manufacturing lead time of workshop is 2, the analysis experiment of the control rule of urgent single receiving / urgent part and the support ability of delivery time is made. The upper limit of each key process path load is set in mixed flow mode. Finally, the simulation results are given. The key variables to guide the implementation process, shorten the manufacturing cycle, improve production capacity, quickly respond to changes in the internal and external environment, enhance market competitiveness, and lay a good foundation for the promotion of profit level, production organization and planning control strategy.
