The welfare properties of Agricultural Futures Market [PDF]
, 2006 本研究的目的是探讨农产品期货市场通过同时改变供给方和需求方预期进而影响市场预期所产生的福利效应。本研究构建了不存在期货交易的现货市场单均衡模型和存在期货交易的期货市场、现货市场一般均衡模型。在理性预期的框架下，本研究分别确定引进期货市场前后的现货价格行为方程，并以此计算相应的社会福利水平。结合数值技术对非线性模型求解的基础上，本研究从三个角度分析期货市场所产生的福利效应：狭义的福利效应（社会福利水平改变程度）、系统效应（市场均衡收敛效率改变程度）和方差效应（对现货市场价格波动改变程度 ...

Guangtongxin yanjiu, 2009 文章提出一种新的数值计算分析法,运用该计算方法得到了密集波分复用（DWDM）系统在衰减、色散走离和受激拉曼散射（SRS）效应耦合条件下的输出信号功率的数值解。并使用MATLAB软件进行了数值模拟仿真,通过数值计算绘出了在短距离传输条件下,不同输入光功率以及不同信道数时SRS效应对光通信系统性能的影响图。

Study on Tobacco- Leaf Inventory Management Strategy Based on Revenues Sharing Mechanism [PDF]
, 2015 文中以福建省两烟物流一体化为背景,建立了基于收益共享机制的烟叶代管策略模型,然后采用SHAPlEy值法来确定收益共享比例,并引入了风险修正因子,修正了物流公司与复烤厂之间的收益分配,探讨了物流公司的整合能力、所承担的风险大小、复烤厂烟叶库存成本占总成本之比对收益共享比例的影响。在此基础上,通过数值分析论证了该方法的可行性。分析结果表明,收益共享比例与物流公司库存整合能力系数、承担风险大小、复烤厂烟叶库存成本占总成本之比成正比,采用带修正因子的SHAPlEy值法对于物流公司与复烤厂之间的收益分配更加合理 ...
