Time-Continuous Capacity 

Use

You define the standard available capacity and the planning parameters for the time-continuous capacity on this tab page. This available capacity is valid for an unlimited period. If you are not working in multiple-shift operations, and want to plan shifts, then you can define the data for the standard available capacity on this tab page.

You can define data for the time-continuous capacity for the following resource types

·        Single-Activity and Multimixed Resources

·        Multi-Activity and Multimixed Resources

·        Line Resources

·        Vehicle Resources

·        Calendar Resources

Integration

If you want to transfer work centers from the R/3 system to SAP APO, the APO system can adopt the standard available capacity from the R/3 system:

·        If you have already maintained APO data for the header data of the scheduling-relevant capacity of the work center, the system adopts the standard available capacity that you specified.

·        If you have not maintained any APO data, then the system adopts the available capacity of the scheduling-relevant capacity type of the work center.

Features

Capacity

You must maintain the following data to define the standard available capacity of the time-continuous capacity:

·        Start and end of daily working time

·        Break duration

·        Rate of resource utilization

·        For multiresources, you enter the capacity and the associated dimension, such as the number of individual capacities. Single resources always have the dimension-free capacity 1.

·        In the case of line resources, you also specify the rates for takt-based scheduling.

 

Planning Parameters

The following parameters are provided for planning on time-continuous capacity (dependent on resource type):

Planning Parameters	Meaning	Resource Types
Setup Matrix	Setup matrix that the system uses to determine the setup time and setup costs of sequence-dependent setup activities on the resource. The setup matrix must be assigned to both the planning-version-independent and the planning-version-dependent resource.	·        Single resources ·        Line Resource
Synchronization Start	The system can synchronize the start dates/times of activities with the same duration and classification.	Multiresources
Time buffer	Time interval in which the components have to be staged at the resource before the planned operation begins.	·        Single resources ·        Multiresources
Maximum overlap	Maximum time (in seconds) by which 2 activities processed at the resource may overlap, before the system interprets the overlap as a capacity overload and generates an alert if necessary.	·        Single resources ·        Multiresources ·        Line Resource
Campaign-relevant	Specifies if the resource can be used for planning production campaigns.	·        Single resources ·        Multiresources

Activities

Calculating the Productive Time

The system determines the productive time in hours from the parameters that you defined for the available capacity according to the following formula:

Productive time = (Working time in hours – Break duration) x Rate of Capacity Utilization

If you have only defined these data, then the productive time corresponds to the standard available capacity of the resource.

Displaying the Available Capacity of the Time-Continuous Capacity

You can display the available capacity of the time-continuous capacity by choosing the Capacity function key. The system creates a list that displays the available capacity in hours for each day. In the Standard column, you can see if the standard available capacity is used for planning (marked with the indicator X).

If you have defined an active capacity variant, the system evaluates the shift sequence and calculates the available capacity.

If you have specified a reference resource, the system calculates the available capacity of the resource from the reference resource data.
