All technical and economic issues are suffering from an uncertainty which needs to be carefully considered in designs. In this model most technical and economic parameters where uncertainties have a significant impact on the outputs are Uniaxial Compressive Strength (UCS) Rock Density (SGr) Bit Life (BL) and Hourly Drilling Cost (HDC).
