【摘要】 现代工程涉及电、磁、声、光和热等多物理场作用以及宏观、细观和微观的多尺度效应,在设计上呈现出多学科交融特点。本文针对现代工程设计的复杂性和发展趋势,重点讨论了近年来在工程优化领域广泛应用的黑箱优化方法,对其中的kriging替代模型进行了较详细的论述,并介绍了常用的几种采样和加点方法。更多还原

【Abstract】 Since the effects of coupled physics and multi-scale analysis on modern engineering problems,the optimization models for engineering design are even more complicated and have to be solved by means of the interdiscipline composed of many different fields.In this paper,the black-box methods in engineering optimization are introduced,then the details of optimization method based on Kriging surrogate model are given.And some methods of sampling and point addition are discussed.更多还原
