Summary: The React Advanced Analytics dashboard enables you to see summary statistics on performance and downtimes. For line-oriented use cases (e.g. electronics or back-end assembly), data can be viewed at the levels of the area and the line. For areas of standalone machines (e.g. injection molding machines), data can be viewed at the levels of the area and the individual machine. You can choose whether to see downtimes for specific shift(s) or across all shifts.
Filters
You use these filters to select which machines you want to view:
- Site: Select the site you want to view.
- Area: Select the area(s) you want to view (or "All" for all areas).
- Line: Select the line(s) you want to view (or "All" for all lines) in line-oriented use cases.
- Machine: Select the machine(s) you want to view (or "All" for all machines) in standalone machines use cases.
- Shift: Select the shift(s) you want to view (or "All" to aggregate across all shifts).
- Group by: Choose Hour, Shift, or Day to indicate the granularity you want statistics shown at.
- Show Minor Downtimes: Yes means that "downtime" will include "minor downtimes" shorter than the Minor Downtime Threshold; No means that "downtime" will exclude them.
- Language: Choose the language you want to view the Downtime Categories and Reasons in.
Remember to use the date picker in the top-right corner to choose the time period you want to view.
Using this dashboard with lines or with areas of simple machines
This single dashboard can be used with lines of machines (as in the electronics or back-end assembly use cases) or with areas of standalone machines (e.g. with areas of injection molding machines). The meaning of some of the panels will change depending on the use case.
If a panel has "Line/Machine" in its title, that panel will show per-line information in assembly line use cases and per-machine information in areas of standalone machines use cases.
Performance panels
Timeline
The Timeline shows the idle time, running time, and downtime in chronological order over the time period selected. Each Line or Machine will be shown on its own bar. In the above screen shot, filters have been set to display a single Line named "L07." When you mouse over an event on the timeline, the hover event will show you the metadata about that event. In the above screen shot, the user has placed the mouse cursor over an unplanned downtime event, so its start time, end time, and duration are shown.
Statistics
The Statistics panel shows the total Units Lost, Time Lost, Throughput, Mean Time Between Failures (MTBF), and Mean Time To Recover (MTTR) for the chosen Line(s) or Machine(s) over the selected time period.
Time Lost is calculated in units of "Line Days" or "Machine Days." One Line (or Machine) being down for a 24 hour period equals one lost "Line/Machine Day" of production. For example, suppose that an Area of seven Lines loses power for two days and there is no production, when normally those Lines would have been running 24 hours a day. Time Lost would be (seven Lines) * (two days) = 14 "Line Days" lost over the two calendar-day period.
Once the lost time has been calculated in "Line/Machine Days," it is converted to Units Lost of potential production using the target takt times for the running jobs over that period. For example, suppose that a Line running Job "Server Board-Top" had a target takt time of 60 seconds and it went down for five minutes. That would equal five units of lost potential production for that Line over that time period.
Throughput is the number of production cycles that the chosen Line(s) or Machine(s) performed during the selected time period.
The time from the previous downtime to the next is averaged over the time period to calculate the Mean Time Between Failures (MTBF). The duration of all the downtimes over the time period is averaged to calculate Mean Time To Recovery (MTTR).
Availability
Availability shows what percentage of the time the selected Line(s) or Machine(s) was running, idle, or in planned, unplanned, or uncategorized downtime during the time period. If you mouse over the ring segments, you can see the percentage converted to an absolute duration.
MTBF/MTTR
The MTBF/MTTR panel charts hourly moving averages of the mean time between failures and the mean time to recovery for each selected Line or Machine during the time period.
For example, suppose that a line goes down two times during the 03:00 - 03:59:59 hour. The first time, it goes down after running continuously for 20 minutes. The second time, it goes down after running continuously for 30 minutes. Those two outages during the hour yield an average MTBF during that hour of 25 minutes. Once the production hour has finished at 04:00, a data point will be placed on the chart at 03:00 showing a MTBF of 25 minutes.
In the same scenario, let's say that it took 5 minutes to resolve the first downtime and 10 minutes to resolve the second downtime, for an average MTTR of 7.5 minutes. Once the production hour has finished at 04:00, a data point will be placed on the chart at 03:00 showing a MTTR of 7.5 minutes.
To View Data for a Shift, You Must Choose a Fully Enclosing Time Range
The next two panels both show data on a per-Shift basis. To see the data for a particular Shift, you must set the Grafana Time Range selector to a time range that fully encloses the Shift(s) you wish to display. For example, let's say that the schedule within ArchFX Cloud for a factory in Shanghai, China defines two twelve-hour Shifts, with the first one starting at 7:00 a.m. in the site's local time zone and the second one starting at 7:00 p.m. in the site's local time zone. To see data for both shifts, you must set Grafana's time range to be [first day] 07:00:00 [local time zone] - [second day] 07:00:00 [local time zone]. For this factory in Shanghai, China, that would be 2023-02-20 07:00:00 CST - 2023-02-21 07:00:00 CST. That will show you the data from 2023-02-20 07:00:00 CST (included) - 2023-02-21 07:00:00 CST (excluded), meaning that the moment of 2023-02-20 07:00:00 CST is included but the moment of 2023-02-21 07:00:00 CST is excluded.
UPH vs Target
For complete shifts that are fully enclosed within the currently-selected time range, "UPH vs Target per Shift" charts what the target was for each shift (red dots) and what the actual production in units was during each shift (blue bar), summed across all Lines or Machines that have been selected. Hovering over a blue bar will cause the data for that bar to be displayed, as shown in the above screen shot.
Throughput by Line/Machine per Shift
For complete shifts that are fully enclosed within the currently-selected time range, "Throughput by Line/Machine per Shift" shows the total production in units across all selected Lines (in Line-oriented use cases) or Machines (in standalone machines use cases) in the selected Area. Each Shift is shown as a separate bar. Within that bar, the production of each selected Line/Machine is stacked as a separate color. Hovering over a bar displays the per-Line/Machine unit totals.
Potential Throughput
Potential Throughput charts how much potential additional throughput was lost summed over all the selected Lines/Machines in the Area during the selected time period due to slow cycles and downtime during periods of time the lines were scheduled to be running. Each point represents one hour, shift, or day of time (depending on the setting of the Group By filter). That point shows how many additional units could have been produced during the preceding hour, shift, or day if it were not for slow cycles and downtime.
Idle time is excluded because no job was running, so there's no basis for converting time to units of lost production. Scheduled downtime is likewise excluded.
For example, let's say that you select Line 1 and Line 2 and look at the chart. From 02:00 through 02:59:59, Line 1 was running a job with a 60-second takt time, and Line 2 was running a job with a 120-second takt time. There were no slow cycles, idle time, or scheduled downtime during the period, only running time and downtime. Line 1 had 30 minutes of downtime (representing 30 units of lost production) and Line 2 had 16 minutes of downtime (representing 8 units of lost production). At 03:00, the chart will show 38 units of lost production due to downtime in the preceding hour.
Downtimes (categorized only) panels
Total Downtimes Duration per Category
Total Downtimes Duration per Category sums the total duration of downtimes by category during the selected time period for all selected Lines/Machines. Each category's portion of the downtime is shown as a percentage. If you hover over a ring segment, you can see the absolute duration of downtime for that category.
Total Downtime Events per Category
Total Downtime Events per Category sums the total number of downtime events by category during the selected time period for all selected Lines/Machines. Each category's portion of the downtime events total is shown as a percentage. If you hover over a ring segment, you can see the absolute number of of downtime events for that category.
Total Downtimes Duration per Reason
Total Downtimes Duration per Reason sums the total duration of downtimes by reason during the selected time period for all selected Lines/Machines. Each reason's portion of the downtime is shown as a percentage. If you hover over a ring segment, you can see the absolute duration of downtime for that reason.
Total Downtime Events per Reason
Total Downtime Events per Reason sums the total number of downtime events by reason during the selected time period for all selected Lines/Machines. Each reason's portion of the downtime events total is shown as a percentage. If you hover over a ring segment, you can see the absolute number of of downtime events for that reason.
Total Duration and Number of Events
This panel shows the total duration of downtimes (in "Line Days" for Lines, or "Machine Days" for Areas of standalone Machines) for all selected Lines/Machines during the selected time period. It also shows the total number of downtime events for the selected Lines/Machines during the selected time period.
If more than one Line or Machine is selected, the "Total Duration" of downtimes can easily exceed the amount of calendar time during the selected time period. One Line (or Machine) being down for a 24 hour period equals one lost "Line/Machine Day" of production. For example, suppose that an Area of seven Lines loses power for two days and there is no production, when normally those Lines would have been running 24 hours a day. Time Lost would be (seven Lines) * (two days) = 14 "Line Days" lost over the two calendar-day period.
Downtime Categories Trend
For each hour, shift, or day during the selected time period (depending on the setting of the Group By menu), Downtime Categories Trend shows the total amount of downtime (across all selected Lines/Machines), broken down by category. The height of the bar shows the total amount of downtime during the hour, shift, or day (summed across all selected Lines/Machines). Each color within the bar shows the amount of downtime during that hour, shift, or day due to that category (summed across all selected Lines/Machines).
When you hover over a bar, you can see the detailed information for that hour.
Downtime Reasons Trend
For each hour, shift, or day during the selected time period(depending on the setting of the Group By menu), Downtime Reasons Trend shows the total amount of downtime (across all selected Lines/Machines), broken down by reason. The height of the bar shows the total amount of downtime during that hour, shift, or day (summed across all selected Lines/Machines).
