摘要
分析了船舶设计中所包含的模糊因素,运用模糊数学方法给出各类模糊因素和模糊主观信息的解析化方法,在此基础上建立了船舶设计的多目标模糊优化模型,并根据工程需要给出了相应的求解方法,最后用算例给予说明.
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.
