基于小批量生产的统计质量控制

Statistical Quality Control Based on Low-Volume Production

以多品种小批量为主的高智能、高柔性自动化生产加工系统是未来的主导生产方式。传统的控制图应用于小批量生产质量控制时 ,存在着“误发警报”概率增加的问题。新的基于小样本的控制图模型 ,其控制界限可靠稳定 ,不受样本组数量的限制 。

High intellectual, high flexible manufacturing system based on multi-type low-volume production is the main mode in future. The paper analyzes the shortcoming of the traditional control chart applied in low-volume production, and presents a new control chart based on a small number of sample, which resolves the issue that there are not sufficient available observations. The control limits is setting reliably regardless of the number of subgroups.
