The GURPS Traveller supplement for designing starsystems (cannot remember
what it is called) had a fairly simple system for binaries (sorry as I can't
find my copy I don't remember what it did for systems with more than two
stars). But for binaries what you did was work out the closest and farthest
distances apart of the two stars. The eccentricity of the orbit and the mean
distances will give you this. Then divide the closest approach by three and
multiply the farthest separation by three. This would give you the stable
orbit bands. Any bodies orbiting their primary at greater than a third the
minimum seperation were deleted unless they were at greater than three times
the maximum separation.
