【摘要】：本文在对M公司酸轧机组产能现状进行分析的基础上,运用约束理论重点研究M公司酸轧机组产能提升方案,目的在于突破产能不足的制约,提升机组生产能力,提高其竞争力。市场的激烈竞争给企业带来了严峻的挑战,合同订单呈现小批量、多品种、高难度的特点,对钢铁行业中的这种连续性生产线而言,生产难度的加大对生产系统提出了更高的要求,如果产能不足将直接增加生产成本,如何对企业生产计划系统进行管理直接影响着企业产品订单的及时交付和企业竞争力。因此本研究对提升机组产能和增强市场竞争力有着一定的理论和现实意义。本文以提升酸轧机组产能为目标,通过定性和和定量分析识别产能不足的瓶颈工序,通过差值法有效甄别导致产线产能不足的真实瓶颈；针对瓶颈工序,从工艺技术攻关和生产管理改进两个角度提出产能提升策略,突破瓶颈工序产能发挥的制约,有效提升了瓶颈工序产能；进一步运用DBR方法对酸轧机组的生产计划和控制系统进行优化,对两个瓶颈工序设置三个功能不同的在线缓冲活套,对瓶颈工序的生产计划进行了详细的排程,通过活套来调节非瓶颈工序的生产节奏以配合和保护瓶颈工序的稳定生产。项目开展后的半年生产产能均完成了目标,实绩证明项目制定的方案是有效的。
[Abstract]:Based on the analysis of the present production capacity of acid rolling mill group in M Company, this paper focuses on the research of capacity upgrading scheme of acid rolling mill group in M Company by using constraint theory, the purpose of which is to break through the restriction of insufficient production capacity and to enhance the production capacity of the unit. Improve its competitiveness. The fierce competition in the market has brought severe challenges to the enterprises. The contract orders have the characteristics of small batch, many varieties and high difficulty. For this kind of continuous production line in the iron and steel industry, If the production capacity is insufficient, the production cost will be increased directly. How to manage the enterprise production planning system directly affects the timely delivery of the enterprise product orders and the competitiveness of the enterprise. Therefore, this study has certain theoretical and practical significance to improve unit capacity and enhance market competitiveness. The aim of this paper is to improve the production capacity of acid mill, identify the bottleneck process of insufficient production capacity by qualitative and quantitative analysis, and effectively identify the real bottleneck that leads to insufficient production capacity of production line by difference method, and aim at the bottleneck process, This paper puts forward the strategy of improving the production capacity from the two aspects of process technology research and production management improvement, which breaks through the restriction of the bottleneck process capacity, and effectively enhances the bottleneck process capacity. Furthermore, the production planning and control system of acid mill group is optimized by using DBR method. Three online buffering loopers with different functions are set up for the two bottleneck processes, and the production plan of the bottleneck process is arranged in detail. Adjust the production rhythm of non-bottleneck process through looper to coordinate and protect the stable production of bottleneck process. Six months after the project production capacity has been achieved, the performance of the project proved that the formulation of the program is effective.
