I believe that if you use the SMURF for constraint based planning, you
have the possibility to provide go/no go time window.
3.11.4 CLASS TimeWindows
The TimeWindows class is optional and may be used to submit a set
of time windows.
Each instance of the TimeWindows class must contain 1 or more
instances of the TimeWindow class described in section 3.11.5.
NOTE ? The TimeWindows class is a specialization of class
Constraints described in 3.10.2 and the generic description of the
parameters can be found there.
The use of the TimeWindows class allows the specification of a set
of one or more time windows that must either all be included or all
excluded in the resulting schedule.
Table 3-37 specifies the use of the parameters in the TimeWindows.
Table 3-37: Class TimeWindows Parameters
If true indicates that the time range specified by the window is
considered to be included.
If false indicates that the time range specified by the window is
considered to be excluded.

Hope you are safe and healthy.
We?ve been discussing with Jean-Michel on the different use cases of the
SMURF and we might have one use case for which we are unable to find a
In our existing tools we have the possibility to mark a pass as forbidden
when requesting for a schedule request. A pass is identified by a station,
a spacecraft, an AOS and a LOS. The ground control center has the
possibility to compute AOS and LOS for the different passes. This way our
planning tool will be able to fulfill all constraints without booking the
forbidden pass. The scenario we managed to make was that the scheduling
tool plans for a list of passes regarding to the constraints and then if
the pass is present, then we need to do a DeleteSrvPkg and then
reschedule again and request for another pass.
Do you have a solution for our use case, a simple one if possible?
