stochastic uncertainty meaning in Chinese
随机不确定性
Examples
- Uncertainty of structure can be classed into two different categories . one is stochastic uncertainty . the other is fuzzy uncertainty
结构的不确定性分为两类，一类为随机性，另一类为模糊性。 - The pavement system with the complicated structure is always considered as a large surface layer bearing on the infinitely deep foundation . due to complexity and variety of materials and stochastic uncertainty of load boundary condition , many mathematic and mechanic problems will occur in obtaining stress and displacement solutions of the pavement system
路面体系在构造上比较复杂，它通常是一个大面层，支承在无限深的地基上，由于体系材料复杂性、多样性和荷载边界条件的随机不确定性，在解算它的内力、位移时会遇到很多的数学和力学上的困难。 - This paper first presents the uncertainty of water resources and the process of fuzzy set theory in this field , then analyzes the current conditions of agricultural water resources and its sustainable developments in our country . based on the researches in this field , considering its character of multi - objective , multi - layer , multi - function and multistage , this paper mainly deals with the fuzziness and stochastic uncertainty of agricultural water resources system . the major contents and research results are as follows : 1 based on chen shouyu ' s fuzzy set theory , this paper presents a fuzzy optimal multi - dimension and multi - objective dynamic programming model , then two methods are given
本文首先阐述了水文水资源的不确定性及模糊水文水资源学的发展现状，分析了我国农业水资源现状及其可持续利用，在论述区域农业水资源优化领域研究现状的基础上，鉴于农业水资源系统优化的多目标、多层次、多功能、多阶段、多维与随机的特征，针对系统中普遍存在的模糊性和随机性开展研究，主要研究内容和研究成果概括如下： 1 、基于陈守煜提出的多目标模糊优选动态规划理论，提出复杂水资源系统的多维多目标模糊优选动态规划问题的两种求解办法：多维多目标的决策序列相对优属度总和最大法和多维多目标阶段模糊优选动态规划方法。
