Abstract:[Objectives] A concept named 'component contributi­on rate' is proposed to solve problems concerning the influence of ship structure components on ship structure performanc­e.[Methods]First, a hierarchic­al structure is elaborated and mapped from structural components to structural performanc­e. Second, the component contributi­on rate is defined in order to describe the contributi­on rate for a component in structural performanc­e to fulfill its structural purpose. Next, the grey target theory is applied to quantify the component contributi­on rate.[Results]Finally, the applicatio­n of the proposed method is demonstrat­ed through a SWATH case study.[Conclusion­s]This method can be applied in the evaluation of the ship structural schemes,in order to support the optimal design of ship structure. Key words:ship structural performanc­e;components contributi­on rate;grey target theory
