Estimating Alarm Thresholds for Process Monitoring Data under Different Assumptions about the Data Generating Mechanism
Figure 15
Realizations of 600 values in arbitrary units (a.u.). In (a) there are 600 MBs with cleanout between every batch of 3 MBs, with the amount to holdup each period having a normal distribution. Subplot (b) is the same as (a), but with the amount to holdup each period having a uniform distribution. Subplots (c) and (d) are for 600 realizations from a normal distribution for comparison.
