摘要
The paper presents the uncertainty hull form optimization design method for minimum EEOI, considering the influence of travelling speed perturbation. Four types of perturbation parameters are addressed and applicable methods for each type are given. Firstly, uncertainty optimization methods: Interval optimization (IO) and robust optimization under moment uncertainty (DRO-MU) are introduced. Then, formula and parameters of EEOI with the numerical method for calculating resistance are described. Finally, hull form optimization model of minimum EEOI is given and four case studies are conducted to verify the feasibility and superiority of the novel approach. Results show that the uncertainty optimization design is of excellent adaptability and reliability in minimum EEOI ship hull lines design.
