物联网平台上两制造商间的制造能力共享策略

借助市场经济理论,分析物联网平台上制造企业之间制造能力共享的策略。考虑物联网环境下可以实现共享的资源和能力的丰富性,建立随机需求下两个制造商之间制造能力共享的模型。通过分析得到:在制造能力实现共享的模式下,两个制造商制造能力的最优准备水平存在,且随单位转移收益的升高而同时升高;集中决策情况下制造能力共享所获得利润不小于分散决策时的利润总和。最后,通过数值分析对上述结论作了进一步的验证。

Optimal ordering and pricing decisions for a target oriented newsvendor

This paper is the first to study pricing and target oriented decision making together in the newsvendor model. Specifically, this paper studies a newsvendor who decides on order quantity and selling price to maximize the probability of achieving both profit and revenue targets simultaneously. First, it is shown that the probability of a newsvendor achieving both targets depends critically on the relative magnitudes of the profit margin and the ratio between the profit target and the revenue target. Second, the closed-form expressions of the optimal order quantity, the optimal selling price, and the maximal profit and revenue probability are obtained. It is shown that if the product has greater price elasticity, the best strategy is always to price lower and order more.

Adaptive tests of regression functions via multiscale generalized likelihood ratios

Many applications of nonparametric tests based on curve estimation involve selecting a smoothing parameter. The author proposes an adaptive test that combines several generalized likelihood ratio tests in order to get power performance nearly equal to whichever of the component tests is best. She derives the asymptotic joint distribution of the component tests and that of the proposed test under the null hypothesis. She also develops a simple method of selecting the smoothing parameters for the proposed test and presents two approximate methods for obtaining its P‐value. Finally, she evaluates the proposed test through simulations and illustrates its application to a set of real data.     

Risk prediction of hypertension complications based on the intelligent algorithm optimized Bayesian network

Hypertension and its related complications could be a major threat issue for cardiopathy and stroke. Effective prevention and control can decrease the incidence rate of complications in hypertension. Based on the medical data of 3062 patients with cardiovascular and cerebrovascular diseases from 2017 to 2018 in a grade-A tertiary hospital in Shanghai, the study identified the risk factors of hypertension complications by text mining. On this basis, the K2 algorithm based on the improved particle swarm optimization was proposed to optimize the structure of the Bayesian network (BN) by establishing a multi-population cooperative search mechanism. Then the optimized BN was used to analyze and predict the incidence rate of hypertension complications. Results indicate that the major indicators of accuracy, sensitivity, specificity, and AUC have been improved, and the proposed algorithm is superior to the common data mining algorithms such as the back propagation neural network and the decision tree. Through the proposed model and algorithm, the high-risk factors were identified and the occurrence probability of hypertension complications was predicted, which could provide the personalized health management guidance for hypertensive patients to prevent and control hypertension complications.

圆柱绕流N一S方程数值解的非线性特性分析

数值模拟并分析了二维圆柱绕流向混沌转捩的情形．通过时间延迟技术和维数嵌入方法对速度时间序列重构相空间，并利用蛎线性动力系统理论方法（诸如相空分析、频谱分析、Ｐｏｉｎｃａｒｅ映射），以及通过对混沌计量（如关联维数、Ｋｏｌｍｏｇｒｏｖ熵、Ｌｙａｐｕｎｏｖ指数等）的计算，对不同雷诺数的Ｎ－Ｓ方程解的特征作了分辨．结果表明，在一定的雷诺数范围内解的是周期或周期的，并且有一个复杂的公叉途径向混沌转捩．     

论反倾销对对外直接投资的影响及其启示

反倾销对对外直接投资的影响是一个在国际学术界逐渐引起关注的问题.本文首先建立了一个反倾销对对外直接投资影响的微观模型,并以美国提起的反倾销为例,对反倾销在对外直接投资过程中的影响进行了实证分析,最后从启示的角度对我国实施的反倾销行为所引发的反倾销跳脱对外直接投资问题提出了政策建议.
