Abstract: Aiming at the limitation of effect evaluation in ship equipment maintenance cost forecasting,which would result in high risks by adopting single accuracy criteria.The evaluation criteria of forecasting methods were s ummarized,which was based on the analysis of researching development on existing forecast evaluation criteria.Then,the characteristics of ship equipment maintenance cost forecasting were analyzed.Finally,combining the above two parts,the evaluation criteria system of forecast methods which fit for maintenance cost of ship equipment is established,which is in favor of improving reliability of ship equipment maintenance cost forecasti ng,reducing forecasting risk,and providing reliable foundation for ship equipment life cycle cost(LCC) forecast and maintenance.
