First, when they are pre-set, the amount of possible information about Indifferent Event tends to be large. Therefore, since the decision is risk tolerant, the Max-Product method of Tanaka et al. is used to calculate the expected utility possibility. Next, in the case of automatic derivation after the fact, the amount of information on the possibility of Indifferent Event is relatively small, so the expected utility possibility is derived using Zadeh’s Fuzzy Event Possibility Measure. Here, it is assumed that the setting of the utility function is independent of the information on the occurrence of the Indifferent Event and is identified by the decision maker by lot drawing using the certainty equivalence method. As a concrete example, we focus on the pass/fail decision of a recommendation test, which is a two choice question in the No-Data Problem, and illustrate the multistage state identification method. .展开更多
通过对1949年至今全国大豆(Glycine max L.)历史数据的整理,详细分析了各地区大豆产量、播种面积和单产变动规律、分布特征和波动周期,探讨了影响中国大豆生产的重要因素,建立了中国大豆单产预测模型(指数拟合曲线、线性拟合曲线和多项...通过对1949年至今全国大豆(Glycine max L.)历史数据的整理,详细分析了各地区大豆产量、播种面积和单产变动规律、分布特征和波动周期,探讨了影响中国大豆生产的重要因素,建立了中国大豆单产预测模型(指数拟合曲线、线性拟合曲线和多项式拟合曲线),对未来(2020—2035年)中国大豆产量进行展望。研究发现,中华人民共和国成立以来中国大豆产量的增加主要来自单产增长;与其他粮食品种相比,中国大豆生产表现出生产地区相对集中、产量波动频率高、波动周期短和波动幅度大的特点;预计2030年中国大豆产量将达0.25亿t,到2035年将增加至0.27亿t,低于美国、巴西等国家的产量水平,但远高于加拿大、澳大利亚以及印度等国家。展开更多
