本文以 S 公司质量管理实例为背景,结合所学管理相关知识,提出 S 公司在质量管
理中存在的质量控制问题，基于对质量管理中过程控制方面的认识以及 PDCA 循环
理论,找出了频繁出现质量问题的原因是过程控制流于形式、非标准化作业、工序管
理的陈旧三方面因素。针对 S 公司质量管理在过程控制问题已经过程控制引起的资
源浪费，生产效率低等问题提出质量管理的改善方案。本文这着重于以下几个方
面：第一、S 公司过程控制必须明确控制点，提高过程控制的有效性和实用性。第
二、以精益管理为基础制定标准化的作业流程，防止质量管理失效的发生。第三、
改进工序，提高过程控制力和生产效率
本人的研究不仅能对 S 公司目前的质量状况有所改善，提高 S 公司的生产效
率，促进 S 公司自身快速发展，也能为其他中小型加工企业中出现的质量问题提供
一定的理论数据和实践参考。机械加工企业通过过程控制，实现产品质量有效提升是
质量管理的一种重要手段

Research on process control in quality management

Abstract
With the many-year development of processing industry in China, the China
processing and manufacturing industry has become the important part of the global
manufacturing industry, in which, mechanical manufacturing industry has occupied a
significant position. It guarantees the high-speed development of each industry in our
country through providing various of machines and equipment’s. In the recent years, the
demand of mechanical products is reducing, therefore, the domestic output is excess, the
processing and manufacturing industry has entered into a hard time, the competition has
become more and more fierce. Mr. Ishikawa Kaoru, the Japanese authority in quality, said
Many industries from Japan can own a very strong competitiveness in the global market,
and can have great amount of export to different countries or areas globally, one of the
important reason is the quality management has been implemented.The S company is an
enterprise focusing on the petrochemical equipment. How to improve the product quality,
increase the productivity, strengthen the competitiveness has become a problem that S
company needs to resolve urgently. The quality management is the major management
method to improve the product quality. However, comparing with the developed
companies, there is still a certain gap on the quality of China products. To analyze the root
cause, it is mainly resulted from the insufficient quality management.
The thesis raises the existing problems on the quality control in the quality
management in the S companies in the background of the real example of the S company
quality management, combining the learnt related knowledge of the management. Based
on the understanding on the process control in the quality management and PDCA cycle
theory, the cause of frequent quality problems is found that there are 3 factors which are
formalistic process control, non-standardized work, obsolete process management. Aiming
at the problems occurred in the process control, the waste of the resources in the process过程控制在S公司质量管理中的研究英文摘要
III
control, the low productivity etc. for the quality management of S company, the
improvement plan has been proposed. The thesis is focusing on the aspects below:1st, the
company the control point must be specified in the company&39;s process control, to improve
the effective and practicability of the process control.2nd, to establish the standardized
work flow based on the lean management to avoid the occurrences of the management
failures.3rd, improve the process to increase the process control force and the productivity.
My research not only can improve the current quality of the S company, increase the
productivity, to facilitate the fast development of the S company, but also to provide a
certain theoretical data and practical reference for quality problems occurred to the other
SMEs. It is an important means to realize the effective improvement of product quality
through the SMEs process control.
