Determining the Valid Available
Capacity
Purpose
You can define different categories of capacity for a resource:
· Standard available capacity of the time-continuous capacity and the SNP bucket capacity
To call up an overview of the standard available capacity generated from the time-continuous capacity and SNP bucket capacity of a resource, choose the relevant pushbuttons on the Time-continuous Capacity and SNP Bucket Capacity tab page.
By choosing the Capacity Profile pushbutton, you can call up an overview of the standard available capacity, the available capacity generated from the capacity variants or the capacity defined externally.
To determine the capacity that is available at a specific point in time at a resource for scheduling, the system takes these different capacity categories into consideration in a hierarchical sequence.
No capacity is available in downtimes.
This process describes how the system determines the valid capacity.
Process Flow
The system checks the resource at the current point in time in the following sequence. If the result of the check is negative, the system moves on to the next step:
...
1. If a downtime is defined for the resource for the current point in time, no capacity is available.
2. If it is specified in the resource that the capacity is determined in an external system,
...
a. And an active variant is also specified at the resource for which a capacity profile with different data exists, the system uses the data defined in this capacity profile
b. And different data exists for the external capacity in a capacity profile for the current point in time, the system takes this variance into account
c. And no active variant is specified and no capacity profile is defined, the system uses the external capacity.
3. If an active capacity variant is specified in the resource, and different data is defined in a capacity profile for the current date, the system uses the capacity defined in the capacity profile.
4. If an active capacity variant, for which a capacity profile does not exist, is specified in the resource,
...
a. And an interval with a capacity that is valid at the current time is defined in this variant, the system uses this capacity
b. And no interval is found with a capacity that is valid for the current time, the system checks if a reference resource is assigned to the resource
i. If the same (not necessarily active) capacity variant with a valid interval exists for the reference resource, the system uses the capacity of the capacity variant for the reference resource.
ii. If a valid interval does not exist in the same capacity variant at the reference resource either, the system uses the standard capacity of the reference resource.
5. If you have also created a capacity profile for the standard available capacity, the system uses the capacity defined in the capacity profile.
6. If a reference resource is specified at the resource, the system uses the standard capacity of the reference resource.
The capacity profile of the reference resource, should it exist, is ignored. If, on the other hand, another reference resource is specified at the reference resource, the system determines the capacity as described here.
7. The system only uses the standard available capacity if it was not able to determine a valid resource capacity for the current point in time during one of the previous checks.
8. If no standard available capacity is defined at the resource, the resource does not have any capacity.
