Bad actor management

When certain components of the process machinery consistently malfunction, we call it bad actor management. 

Another way to think of bad actor management is to liken it to Pareto s law, where 20 per cent of the components are causing 80 per cent of the problems. Many of the causes previously identified in connection with machinery component failure modes lend hand to bad actor management however, some of the more significant are listed as follows ... 

Bad actor management is preoccupied with the following necessary problem solving steps ... 

A critical analysis of the alarm metrics can result in significant improvements in alarm management. In particular, it can identify potentially dangerous alarm fioods where operators are overwhelmed by a large number of alarms in a small time interval. It can also delineate bad actors. An industrial example of an alarm fiood is shown in Fig. 10.6 identification of the associated bad actors is shown in Fig. 10.7. Analysis of bad actor alarm data can identify process problems or alarm limits that are inappropriate (e.g., too aggressive). Figure 10.7 indicates that only four alarms generate over 40% of the total number of alarms.
