This article is intended to explain how to use the Shift Times menu so that users can define when their production is in progress or not. By doing so, metrics are correctly calculated on certain dashboards related to factory or assembly Line KPI's and behaviour is correctly carried out where shifts time information is needed.
Certain dashboards within DeMeter are closely linked to ongoing production. They can show the Overall Equipment Effectiveness (OEE) of an assembly line/factory as well as its constituents (Performance, Availability and Quality). Dashboards can also display ongoing alerts from stations/tool controllers and metrics like days since last accident or even rate of Direct OK from a production environment.
All of the above are affected by whether or not production is in progress, hence why it's important for the DeMeter Service(s) to understand when your production environments are active or inactive. By having this information available metrics can be correctly calculated and information is correctly conveyed to viewers of dashboards so that they have access to accurate information.
You are in full production based on your defined shift times. There has been no stoppage and operators are working as expected, producing exactly the number of parts at the expected run rate. DeMeter will count each new OK/NOK result from Pivotware connectors and affect the environment's OEE accordingly. Everything is reading as 100% in OEE ! Wow ! Go Team !
Suddenly an operator raises a very high level alert message stopping the line from running. DeMeter receives this call from Infinity Client and therefore displays "Stop" on all dashboards associated to that environment so everyone knows that there is an issue affecting the line/factory. DeMeter will then begin lowering the Availability of the affected environment because it was not able to produce for x period of time.
This kind of metric can only be done accurately by having shift times defined as 1 minute of downtime in a 4 hours long shift represent twice as much unavailability as in an 8 hour shift.

When defining a shift or set of shifts, users are able to define an appropriate name for the planning of production as well as when the times defined are applicable to dashboard calculation and actions.
- Name - Define the name of your shift/set of shifts.
- On which days - Define if the times (defined in the Slots menu) are repeated on multiple days throughout the week.
- When - Define an applicable start and end date for the times defined within the "Slots" menu.
- Exceptions - Define specific dates where the times defined within the "Slots" menu are not used.
When defining a shift or set of shifts, users are able to define the times that are applicable to their production for a given day. In order to define the types of ongoing activity as well as the expected start and finish times, users use the "Slots" menu.
You can use drag and drop to define the start and end time of a time slot within your slots menu:
On releasing the mouse button, a pop-up menu will appear allowing you define the shift time(s) in more detail as well the slot type.
Click "Save" to confirm the addition of the slot.
By defining the slot type, start times and end times, users have the ability to define their shifts from start to finish:
Different slot types results in different behaviour and have an intended usage in order for dashboard to be clear to viewers.
|Slot Type||Intended Usage||Dashboard Appearance||Behaviour|
|Production||Indicates that production is ongoing without any issues stopping the line/factory.||Production|
|Preparation||Indicates that preparation such as cleaning, stock taking or similar is ongoing.||Preparation|
|Break||Indicates that a break in production is ongoing.||Break|
|Maintenance||Indicates that planned maintenance of the production environment is ongoing.||Maintenance|
