There are several mathematical models in present researches or applications about uncertain structural analysis, such as stochastic model, fuzzy model, convex model and interval one etc.
现在结构分析中应用的不确定性模型主要有随机模型，模糊模型，凸模型以及区间模型。
In this paper, the uncertainty analysis and design problems for structural and multidisciplinary system were investigated in detail base on a non-probabilistic approach that is convex model theory.
本文基于不确定参量的凸集合描述，研究了结构和多学科系统的不确定性分析与考虑不确定因素的优化设计问题。
