[eclipse-users] Applying conditionals on ranges

One of the requirements of the model I am trying to simulate using Eclipse
is to be able to apply conditionals on variables where different outcomes
lead to different constraints.

For example,

(A > 75 -> B $= 0.95 * A; B $= A)

i.e. depending on A's value, B may be either 0.95 of A or A.

Since A may be a range this is of course problematic.

Anyone have any ideas about how this may be handled?

Thanks
