When non-stacking abilities match, the maximum is used. By non-stacking, note that the description of the RFs, etc, note that only one per planet matters; or, one per system (for a System RF). Actually, it's the *ability*, not the component, that isn't stacking.

A Robotoid Factory, for instance, has *three* abilities: roughly, "Increase FOO Production by X%" for each resource. A Mineral Scanner uses the exact same abilities (well, only one of them), so unless the MS level (I,II,III) is greater than the RF level, it's not giving you anything; "Increase FOO Production by X%" is a non-stacking ability. An MS II with an RF I should give you +20%/+10%/+10% resource production, methinks.

Note, however, that "Increase FOO Production by X% in System" is a separate ability from the per-planet one, so a System RF *does* stack with an RF, or with a Mineral Scanner. But you won't get any benefit from an SMS whose bonuses are less than or equal to those of a SRF since this also is a non-stacking ability.
