Question

5. Suppose you are working in a ceramics factory and you are constructing control chart for an critical feature with batches of very fragile parts that common get broken during the measurements. You always start with 8 parts, but sometimes a few of them are broken while measuring them. What type of control chart would you construct and why

Answer 1

Explanation:

Analyzing the above scenario, the ideal type of control chart for construction would be the EWMA control chart integrated with the VSS and VSI control, because unlike traditional charts, it considers the variable sample size (VSS) and the variable sampling interval ( VSI) and therefore are more effective in considering the variations in the process in the control, which was what happened in the question above, since during the process of building the control chart there are some changes resulting from the breaking of the ceramic pieces, so it is ideal to build a graph that detects the changes in a more complete way.
