统计质量控制导师（进一步咨询，加我微信：415818818）-Statistical Quality Control Guidance

Example

Constructing and interpreting an X-bar and R chart for monitoring the diameter of machine parts in a manufacturing process.

Scenario

In a scenario where a company aims to maintain the quality of its machine parts within specified limits, the tutor explains how to set up control limits, plot data points, and identify any signals indicating out-of-control processes.

Example

Designing an acceptance sampling plan based on the acceptable quality level (AQL) for a batch of electronic components.

Scenario

The tutor helps students understand how to determine sample size and acceptance criteria based on the desired level of consumer risk, guiding them through the process of using statistical methods to infer the quality of the entire batch from the sample.

Example

Calculating and interpreting the Cp and Cpk indices to evaluate the capability of a new production line.

Scenario

Students are guided through the process of assessing whether a production line can consistently produce items within specification limits, using process capability indices to measure how well the process fits within the desired tolerance range.

Example

Implementing a factorial experiment to understand the impact of temperature and pressure on the yield of a chemical process.

Scenario

In this use case, the tutor shows how to set up an experiment, collect and analyze data, and interpret the results to make informed decisions about process improvements.
