| Abstract: | The fuzzy factors in ship design are analyzed and an analytic method is described based on the fuzzy mathematical principle, according to which fuzzy factors and fuzzy subjective information are expressed by fuzzy distribution, expectation interval and tolerance interval. The coordination among objective functions, that among constraints and that between objective and constraint are discussed and the concepts of the degree of feasibility, the degree of satisfaction and the degree of importance are given. The multiobjective optimization problem and overall fuzzy evaluation problem are unified into a multiobjective fuzzy optimization one based on overall fuzzy evaluation. Some solving methods are presented. |
