About the Bad Actors Widget
The Bad Actors Widget provides a comprehensive overview of machines in a production environment that are causing significant concerns due to the presence of Extreme or Serious faults. The objective of this widget is to highlight the machines that notoriously require attention and corrective actions.
Typically, the widget displays the top five machines with the highest bad actor score. The bad actor score is a metric that evaluates the severity and likelihood of a faults. It considers the number of Extreme and Serious faults detected in each machine, as well as factors like fault recurrence, impact on production, and so on.
By displaying the top five machines with the highest bad actor scores, the widget helps prioritize and focus attention on those machines that are causing the most trouble and require immediate attention. It allows operators, maintenance personnel, or other relevant stakeholders to quickly identify critical machines that require immediate troubleshooting, repairs, or maintenance actions in order to reduce downtime, improve efficiency, and ensure smooth production operations.
About the Bad Actors (Troublesome/Intractable Machines)
A Bad Actor is a machine that has persistent and recurring serious or extreme mechanical faults that pose a significant risk to production. A Bad Actor machine, unlike a machine with a single fault that can be repaired, has ongoing issues that may reoccur even after repairs have been made. This never-ending cycle of mechanical failures compromises its dependability and reliability, making it problematic and potentially disruptive to operations.
The following factors can affect the Bad Actors:
- Faults that are new and unique: Bad actors may encounter faults that are not previously observed in other machines. The presence of new and unusual faults indicates a more serious underlying problem in the machine's design, construction, or operating conditions.
- Fault Classification: A variety of flaws contribute to the problematic nature of bad actors. Understanding the different types of faults allows for more targeted troubleshooting and maintenance efforts.
- Faults' Duration: Bad actors frequently exhibit flaws that last for an extended period of time. Analyzing the duration of faults assists in identifying machines that experience issues on a regular basis, necessitating more focused attention for resolution.
- Recurring flaws: The tendency of bad actors to have the same or different recurring problems is a key characteristic. Tracking and documenting recurring faults aids in the identification of root causes and the development of effective mitigation strategies.
About the Bad Actors Details Page
The View Details button on the Bad Actors widget enables you to view the details page, displaying a list of machines, along with columns presenting factors associated with the Bad Actor. Each factor is scored and totaled to rank the assets from worst actor to less severe ones. By default, the data is displayed for the last 12 months. You can change the time period to view data based on your requirements.
The following columns are displayed:
| Column Name | Description |
| Asset Name | Name of the machine along with the hierarchy (Plant > Area > Machine). |
| Bad Actor Score | The percentage of tests that exhibit at least one EXTREME or SERIOUS fault. |
| % Tests Priority |
The percentage of tests that detected at least one EXTREME or SERIOUS fault. For example, if a machine undergoes a total of 10 tests within a given time period, and two of those tests reveal two extreme faults and two serious faults each, then the Tests Priority percentage is computed as 20% (2/10 * 100). The same percentage value is also presented as the Bad Actor Score. |
| % Tests Healthy |
The percentage of tests that detected SLIGHT or OK faults. For example, if a machine undergoes a total of 10 tests within a given time period, and two of those tests reveal two SLIGHT faults and two OK faults each, then the Tests Healthy percentage is computed as 20% (2/10 * 100). |
| # Unique EXT Faults | Displays the number of unique EXTREME faults detected in the machine. It displays a list of these faults and the number of occurrences for each fault. EXTREME faults typically indicate severe issues or malfunctions in the machine. |
| # Unique SER Faults | Displays the number of unique SERIOUS faults detected in the machine. It displays a list of these faults and the number of occurrences for each fault. SERIOUS faults indicate significant issues or malfunctions that require attention and may affect the machine's performance or safety. |
| Total Machine Tests | Displays the total number of tests conducted on the machine within a specific time period. It provides an overall count of all the tests performed, regardless of the fault detected or severity level. |
| Compliance Periodicity | Displays the frequency at which the machine is tested for compliance. |
| MID Completion Score |
Represents the progress made towards completing the machine template and configuration for automated diagnostics and/or manual analysis. It is a metric that indicates how much of the necessary information and configuration for machine diagnostics has been completed. The score is displayed as a percentage, with a higher score indicating a higher level of completion. It helps in tracking the progress of the machine template and configuration, ensuring that all necessary data, parameters, and configurations are in place for effective diagnostics. |
