课程名称：七大质量控制工具、质量控制与保障（六西格玛、PDCA） 概述：本课程涵盖了决策与问题解决方面极为重要的主题，主要教授如何解决问题并选择合适的工具。课程重点介绍七大质量控制工具（如过程流程图、控制图、直方图、检查表、散点图、帕累托图、因果图），这些工具用于深入了解过程中的不确定性和异常情况。它们帮助分析生产过程，识别关键问题，控制产品质量波动，并提供解决方案以避免未来缺陷。 在质量保证领域，还介绍了其他不同工具，如PDCA（计划-执行-检查-行动）循环、六西格玛、过程能力（Cp和Cpk值）、ISO、ASTM和ASME标准等，这些工具有助于优化过程，解决基本问题。质量管理工具仍被视为处理各种质量问题的黄金标准，常与当前广泛使用的过程改进方法共同实施，包括六西格玛的各个阶段和持续改进过程。 此外，课程还提及计量学，即测量的科学，定义了用于实验和质量控制的测量仪器特点。课程说明了在过程开发和规划中指定仪器性能的重要性，并通过简单的统计模型展示了一个基本的计量原则：测量仪器的性能应比要测量的对象好十倍。 课程还探讨了准确性和精确性的定义。例如，国际计量标准是米，如果仪器读数为一米，则其准确性是与国际标准的对比。精确性则指的是测量的细致程度，通常可通过检查仪器显示的数字位数或最小刻度来确定。 总之，该课程为学习者提供了丰富的质量控制知识，致力于帮助组织有效处理质量问题和提高生产效率。
This course has been covered most of the topics which you should need to know as it is very important in term of decision-making and problem-solving but the main thing is that it solves the problem and allow you to decide on TOOLS ( 7QC tools such as process flow chart, control chart, histogram, check sheet, scatter diagram, Pareto chart, cause, and effect diagram ), so these are the 7 QC tool which tells about the reality of uncertainty and the unusual thing which occur during processes. They are used to examine the production process, identify the key issues, control fluctuations in product quality, and give solutions to avoid future defects.In QA there are different tools such as PDCA (plan do check act) cycle, Six Sigma, Process Capability (Cp and Cpk) values, ISO, ASTM, and ASME standards, so these will tell about the concepts of optimization processes, these are the tools which facilitate the organization to resolve the basic problems and these quality management tools are still considered the gold standard for troubleshooting a variety of quality issues. They are frequently implemented in conjunction with today's most widely used process improvement methodologies, including various phases of Six Sigma and continuous improvement processes.Metrology is the science of measurement. Characteristics used to specify measurement instruments for experiments and process or quality control are defined. While there are numerous ways to make process measurements, specifying instrument performance is an important part of process development and planning. A way to make these specifications is illustrated with a simple statistical model that demonstrates the metrology rule of thumb that the instrument should be ten times better than what you want to measure.Accuracy is the degree of conformity to a standard or true value.For example, since the international standard for length measurement is the meter, if an instrument reads a meter, its accuracy would be in comparison to this international standard.Precision defines the degree of refinement with which a measurement can be stated. This can usually be determined by inspecting the instrument and finding out the number of digits displayed or the "least count".For example, on a meter scale, the least count might be 10 mm, or for a digital micrometer the number of decimal places on the liquid crystal display indicates the precision, in Metrology, there are unique measuring instruments which are used for measuring the product accuracy and precision.
