  The High-Energy Beam Transport system of GSI Campus is a complex system of
interconnected beamlines between SIS18 synchrotron and multiple experimental
stations and storage rings. This system is designed to be flexible and each
experimental station can be reached by several beam paths. The quadrupole
settings must fulfill constraints due to the beamline acceptance, limitations
of the installed magnets and experimental requirements. The number of degrees
of freedom is large and leaves operators with a vast number of possible optics
configurations. The choice of a particular configuration is often a matter of
compromises, very specific requirements, operational experience and personal
style. Once a satisfying configuration is found, the space of possible
solutions is usually not explored any further. Here the Monte Carlo method is
used to probe the space of all possible beamline optics configurations. The
focus is on a particular section, the HADES beamline, because this is one of
the most demanding lines due to high beam intensities required by the
experiment. The presented analysis gives an overview of the possible settings,
insight into beamline potential and flexibility and supports the choice of an
optimal operational setting.
