Some research work on uncertainty analysis on numerical computation of ship model resistance is carried out. The method and procedure of verification is based on orthogonal design and variance analy-sis methods. The method and procedure of validation are based on statistic inference theory. Uncertainty analysis and assessment on numerical computation of ship model resistance for DTMB5415 are carried out. Significant factors and their interactions which strongly effect on the result of computations and all uncer-tainty components are obtained. Some suggestions are put forward to lower the uncertainty in numerical com-putation for ship model resistance.
