Use this option, to define a kind of resource group without a detailed planning of the elements. A resource can represent a group of machines (e.g. 5 milling machines) or a group of workers (e.g. 5 technicians). To do so, enter a number greater than 1.
Example: 5 employees are working on one machine. They are not planned separately -> enter 5
The resource represents a person who can work in parallel on 5 turning machines -> enter 0,2
IMPACT ON CAPACITY PLANNING:
The field "planned capacity" and "Number of machines / persons" are multiplied, resulting in the total capacity of the resource. (s. resource scheduling calendar)
In capacity planning, only one machine from the group is dispatched to minimize set-up times. If you want to prevent this, enter the group with only one machine but with the corresponding multiplied planned capacity.
Attention: If the APS calculation is planned as "backward", no resource limits should be checked, and the setting of this field > 1 results in the system not doing a detailed capacity planning.
Beas only calculates with the total available capacity for a day. In this example the resource has 3 * 8hr. = 24 hrs. per day.
As Beas only plans with the capacity, the “start time” is the same for all resources and. The given start time can be ignored, also the given end time, only the day is relevant.
Example:
All WO’s need the resource for 5 hrs.
We assume the calculation starts the next day at 8:00 and the day “ends” at 16:00 (this is 8 hrs. working time for one machine)
Based on this, the calculation works as follows:.
1. WO:
Starts 8:00, End:13:00, takes 5 hours from the 24 --> now for next WO 19 hours remain
2. WO
Starts 8:00, End:13:00, takes 5 hours from the19 --> for next WO 14 hours. remain
3. WO
Starts 8:00, End:13:00, takes 5 hours from the14 --> for next WO 9 hours remain
4. WO
Starts 8:00, End:13:00, takes 5 hours from the 9 --> for next WO 4 hours remain
5. WO -->
Starts 8:00, takes the remaining 4 hours --> there is 1 hour less to finish at this day.
This 1 hour is taken to the next day and the WO ends the next day at e.g. 9:00.
REMEMBER: The start and end times are theoretical and are set normally by the defined starting time of a machine, and the duration of the operation.
Important: If this value is higher than 1, the Quantity tool field value is ignored by the system.
