[cssm] [CSSM] SMURF forbidden pass use case

[Martin.Unal at esa.int]

Hello

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

Dear all, 
 
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 
response.
 
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? 
 
Best regards,
Claudia Ciocirlan
