摘要
本文给出了一个船舶板架结构交互式多目标模糊优化设计方法,主要内容包括: (1)考虑使用、设计、建造过程中的不精确因素,引进相应的隶属函数使模糊目标和约束定量化。 (2)适当兼顾重量、可靠度和布置等多项质量指标,使优化过程能体现设计者的观点和正确决断。 (3)为提高优化算法的效率,采用了分级优化方法。 基于以上各点,运用模糊集理论,导出了一个实用优化方法并编制了程序系统。
In this paper an interactive multiobjective fuzzy optimization design method is proposed for grillage structures.Considering the imprecision in use, design and construction, etc., the authors assume that the objective functions and some of the constraints in the optimization problem are fuzzy. By introducing the corresponding membership functions we can quantify the fuzzy objectives and constraints. In addition, the weight, reliability and arrangement of structure are considered as the objectives In order to improve convergence, the multistage, hierarchical optimization and monotonicity analysis are employed. A practical pogram system was developed on a microcomputer.
