  1. Settings 1-3 consider different values of lead time variability of intermodal transport (low to high), settings 4-6 have different values of demand variability (low to high), settings 7-9 consider different cost differentials of road versus intermodal and settings 10-12 vary the target service level (90, 98 and 99%)
