Probability theory in fuzzy sample spaces 总被引:2,自引:0,他引:2
This paper tries to develop a neat and comprehensive probability theory for sample spaces where the events are fuzzy subsets of The investigations are focussed on the discussion how to equip those sample spaces with suitable -algebras and metrics. In the end we can point out a unified concept of random elements in the sample spaces under consideration which is linked with compatible metrics to express random errors. The result is supported by presenting a strong law of large numbers, a central limit theorem and a Glivenko-Cantelli theorem for these kinds of random elements, formulated simultaneously w.r.t. the selected metrics. As a by-product the line of reasoning, which is followed within the paper, enables us to generalize as well as to bring together already known results and concepts from literature.Acknowledgement. The author would like to thank the participants of the 23rd Linz Seminar on Fuzzy Set Theory for the intensive discussion of the paper. Especially he is indebted to Professors Diamond and Höhle whose remarks have helped to get deeper insights into the subject. Additionally, the author is grateful to one anonymous referee for careful reading and valuable proposals which have led to an improvement of the first draft.This paper was presented at the 23rd Linz Seminar on Fuzzy Set Theory, Linz, Austria, February 5–9, 2002. 相似文献

This paper uses the Malmquist index to examine the sources of Total Factor Productivity (TFP) in Chinese agriculture. The
overall goal of this study is to create a framework for assessing the trend of China’s agricultural infrastructure and to
measure its impact on Total Factor Productivity. The main methodological contribution is to provide more contributive measure
of crop-specific technologies. Based on the province-level panel data set during 1988–2002, the primary finding is that infrastructure
has positively and statistically significant association with the estimated coefficient on Total Factor Productivity for rice,
wheat, maize, and bean.

目前河北省金融业发展水平较低,要建设沿海经济社会发展强省,河北省必须首先成为一个金融强省。河北省金融业定位于围绕京津两个金融中心的区域性产业金融,即立足河北省区域,服务于“三农”、京津冀梯度转移产业、港口产业和海洋产业。应制定金融产业发展规划,采取优化金融生态环境,调整金融产业结构,整合金融资源,开放金融市场等措施来推动金融产业的发展。 相似文献

Wheat yields from reported performance test results are of economic importance to wheat producers, since their profits depend on selecting the optimal variety for their location. However, our data shows differences in absolute and relative wheat yields between commercial and public wheat breeding program's performance test data in Kansas. Newly available data are used to test if the difference in yields arose from potential selectivity bias, and to determine the contribution of private and public wheat breeding programs to varietal yield improvement during 2007–2012. Both Heckman selection models and multiple regression showed no statistical evidence of the potential presence of selectivity bias rather, managerial practices, agronomic conditions, field location, and inherent genetic traits of the seed variety were identify as the source of yield differences. 相似文献

针对鹤煤九矿井下硐室出现浆皮开裂、底臌等类似现象,采用相似模拟的方法,以鹤煤九矿31采区避难硐室临近硐室群实际地质资料为基础,研究分析了给定应力环境下不同支护方式时硐室围岩的变形破坏情况、失稳过程。作者认为,随着顶部压力的逐渐改变,顶板裂隙逐渐增加,裂隙深度和宽度逐步增加,巷道出现离层、底鼓,进而呈现大面积破坏。该结果对区段巷道布置与加固方案优化有一定的参考价值。 相似文献
