Firstly , this paper compares the common methods to uncertainty analysis based on being definite the elemental conception of project economic evaluation 首先,本文在明确项目经济评价基本概念的基础上,对不确定性分析的常用方法进行了比较。
An entire analysis on the closed loop system with the controller is presented , including stability analysis , response analysis , parametrical uncertainty analysis , and so on 最后对开环系统及控制器作用下的闭环系统分别作了一个全面的分析,包括稳定性分析、响应分析等。
Through uncertainty analysis , the testing precision of quenched rail surface hardness has met the requirements 1 hrc of measurements in production , and the testing example is given 经不确定度分析,达到了工业上淬火钢轨踏面硬度检测1hrc精度的技术目标,并给出了测试实例。
It is able to make investor acknowledge the risk of project in all - sided , and efficiently control the variety of factors which affect the project mostly by taking uncertainty analysis , and then to enhance scientific decision - making and to lessen the loss of investment 通过不确定性分析,可以使投资者较为全面地了解项目的风险,有效地控制对项目影响较大因素的变化,从而提高决策的科学性,减少投资损失。
Probability analysis can take risk evaluation of project all - sidedly in the common methods of uncertainty analysis , but it is difficulty to conclude the probability distribution of uncertainty factors " variety which affect project . so it is not applied widely in real operation 在不确定性分析常用的方法中概率分析能够全面地对项目风险进行评价,但是因影响项目的不确定性因素变化的概率分布较难确定,所以在实际操作中没能得到广泛的应用。
In the paper , we systemally analysised the basic theory and method of the uncertainty , and researched the detection methods and uncertainty analysis of the measurement standard apparatus and important parameters in production process , which is necessary in turbine production . also we brought forward the structure and technique of the computer realization based on the uncertainty quality information . and we developed the uncertainty software , which is applicable for the practice in works 本论文在系统分析不确定度基本理论与方法的基础之上,研究了针对汽轮机生产所需的计量标准器与生产过程中重要参数的检测方法和不确定度分析,提出了基于不确定度质量信息的计算机实现的框架与技术,研制了适用于工厂实践中使用的不确定度分析软件。
Finally , a new decision - making method would be proposed to ensure that the operation manager of the firm could make a correct decision on whether the factory ’ s capacity should be changed as well as its volume . consequently the uncertainty of the long range capacity planning in semiconductor manufacturing could be controlled effectively . then the high level uncertainty analysis of long range capacity planning ? factory ’ s space resource planning was discussed in detail 本文首先对半导体长期生产能力计划过程中的不确定性进行了研究:定义生产能力计划过程中的关键不确定性因素;量化这些关键不确定因素对生产能力的影响;在此基础上,提出一种新的决策方法,保证工厂运营管理者正确做出是否改变以及改变多少生产能力的决策,从而达到有效地控制半导体长期生产能力计划过程中不确定因素的目的。
