| dc.description.abstract (摘要) | A single chart, instead of X-bar and R charts or X-bar and S charts, to monitor simultaneously the process mean and the variability if found would cut down the time and effort. Some researches have been done in finding such charts. In reality, process target is more important than process mean. A much easier average loss chart is first proposed here to detect the increases in the difference of the process mean and the target and the variability simultaneously. An example of the customer complaint processing time of the customer service center of an IT company shows the application and the performance of the proposed average loss control chart. Furthermore, a more efficient optimal average loss chart with variable sampling intervals is proposed and performs better than the average loss chart with fixed sampling intervals and the Shewhart joint X-bar and S charts. Some numerical analyses demonstrated the findings. [ABSTRACT FROM AUTHOR] | en_US |
