文摘The development of multidisciplinary design optimization method and its broad application prospects in ship design are presented.The collaborative optimization is described in detail.According to its disadvantage,a dynamic penalty function method is proposed.It is based on the modification of the system level optimization problem,and is turned into an unconstrained optimization problems.It can reduce the difficulties and improve the calculation accuracy.A resistance and structural optimization problem of certain SWATH is simplified and solved,and the final result lowers fuel consumption,and shows that this algorithm application in ship's conceptual design is feasible.
