自有品牌主机板抽样检验分析研究
发布时间：2019-01-03 14:08
【摘要】： 产品质量检验是质量管理活动中不可缺少的重要手段,也是客户能够得到合格乃至满意产品的重要保障。在产品质量检验活动中成品检验是模拟客户端实际使用条件的一种检验方式,其检验数据不仅可以反馈出企业内部产品整体质量变化趋势,也可以反馈出产品在客户端的质量表现状况,其在企业内部的检验活动中占据十分重要的地位,故本文所研究的质量检验主要是指成品检验。 自有品牌主机板的成品检验方式是完全由企业自身制定,但其是否科学合理需要研究。本文首先通过分析接收概率和抽检特性曲线(OC曲线)论证了自有品牌主机板成品检验采用百分比抽样的不合理性,然后通过分析自有品牌主机板实际生产流程,并运用过程平均模型构建了符合自有品牌主机板实际质量水准的成品抽样检验方案。本论文为主机板企业建立适合自有品牌主机板实际质量状况的抽样检验方案提供了科学的理论依据,为有效监控自有品牌主机板产品质量波动趋势奠定了基础,从而达到改善提升产品质量之目的。
[Abstract]:Product quality inspection is not only an indispensable means in quality management activities, but also an important guarantee for customers to get qualified and even satisfied products. In the product quality inspection activity, the finished product inspection is a kind of inspection method which simulates the actual use condition of the client, and its inspection data can not only feedback the overall quality change trend of the product inside the enterprise, It can also feedback the quality performance of the product in the client, which occupies a very important position in the inspection activities of the enterprise, so the quality inspection studied in this paper mainly refers to the finished product inspection. The finished product inspection method of the own brand motherboard is made entirely by the enterprise itself, but whether it is scientific and reasonable needs to be studied. In this paper, the irrationality of percentage sampling is demonstrated by analyzing the reception probability and the characteristic curve of sampling (OC curve), and then the actual production process of the private brand motherboard is analyzed. The process average model is used to construct the sampling inspection scheme of finished product which accords with the actual quality level of private brand motherboard. This paper provides a scientific theoretical basis for the mainboard enterprises to establish a sampling inspection scheme suitable for the actual quality status of the own-brand motherboard, and lays a foundation for effectively monitoring the trend of the quality fluctuation of the own-brand motherboard products. In order to achieve the goal of improving the quality of products.
