基于差异产品的政府最优R&D补贴策略研究

本文建立考虑产品差异的三阶段双寡头博弈模型:第一阶段政府选择R&D(Research and Development)补贴率,第二阶段企业确定自己的R&D水平,第三阶段企业确定产品价格进行伯川德竞争。根据双寡头在第二和第三阶段是否合作,给出了R&D竞争、R&D卡特尔、共同实验、技术共享联盟和研究共同体等五种R&D策略,得到了相应的政府最优R&D补贴率。研究表明,当技术溢出程度较低且产品水平差异不大时,政府给予采用R&D竞争策略企业的补贴率不高于采用R&D卡特尔策略的企业;当技术溢出程度较高且产品水平差异较大时,结果则相反。在政府进行最优补贴后,从促进技术进步、扩大企业规模以及社会福利最大化的角度来看,五种R&D策略中,共同实验最差,技术共享联盟和研究共同体则最优。     

再制造逆向供应链协调的奖励与奖惩机制设计

设计了政府的奖惩机制,建立了7种情形的决策模型,研究了5种情形下激励机制对于引导回收商提高回收量的有效性。结果表明:制造商对于回收商的奖惩机制不能有效协调逆向供应链;政府对于回收商或制造商的奖励机制均能有效协调逆向供应链且效果相同;政府无论给予制造商还是回收商奖惩机制均能有效协调逆向供应链;政府给予制造商比给予回收商奖惩机制更能调动制造商和回收商的积极性;奖惩机制与奖励机制在引导回收商与制造商的作用方面相似,两种机制下的均衡价格相同,但受到奖惩机制的回收商或制造商的利润与奖励机制相比有所减少,减少量与奖惩力度成正比。     

基于杂合遗传算法的工艺路线可变Job Shop调度研究

提出一种将遗传算法与启发式规则、模拟退火法等搜索方法结合在一起的杂合遗传算法,用于求解工艺路线可变的JobShop调度问题。通过对某双极型集成电路封装企业的JobShop调度仿真,结果表明算法是有效和可行的。     

在ARIMA(0,1,1)需求下的牛鞭效应与信息共享的评价

本文考虑一个包含一个供应商和一个零售商的两级供应链,研究在需求模型ARIMA(0,1,1)下牛鞭效应的量化和信息共享的价值,比较信息共享之前和之后的差异,其结果表明信息共享能给供应商带来减轻牛鞭效应、减少现有平均库存以及降低成本等好处。     

基于方案贴近度的不确定型多属性决策模型

针对属性权重不能完全确知的不确定型多属性决策问题,提出了衡量决策方案的一个新指标-方案贴近度,并给出了一种基于方案贴近度的决策模型。通过实例说明了该模型的合理性和可行性。     

多次投资情况下企业最优容量投资策略研究

与仅考虑一次投资机会情况不同,研究分析了多次投资机会对企业最优容量投资策略的影响,利用实物期权方法建立了企业投资时机和容量选择模型.研究结果表明当拥有较多的投资机会时,企业将会拥有较大的容量投资期权,并会提前实施投资,而且最终投资达到的容量规模也越大.     

Energy and U.K. agriculture

This paper makes the point that although U.K. agriculture has become more efficient in many ways, it has become less efficient in its use of energy. Moreover, although farming utilises less than 3 per cent of national power energy consumption and produces over 40 per cent of the nation's food, there are no predominant users of energy in the U.K. Thus small savings in each individual industry, including agriculture, must be effected. How this can be achieved is discussed. But the paper concludes that it may well take another ‘energy crisis’ before farmers and growers respond by modifying their production systems accordingly.     

Futures forecasting for strategic planning at general electric

Without in any way denying that there are forces for stability, I want to state, as strongly as I can, my conviction that change is now more rapid, more complex and more pervasive than ever before in human history. There are forces loose in the world, particularly in the ‘post-industrial society’ of the United States, that go far beyond the youth movement in creating change. As a result, it is utterly unrealistic to pretend that business can continue to plan its strategies in the traditional mode.     

Verbal and Nonverbal Dynamics of Privacy, Secrecy, and Deceit

We discuss the ways in which deception can be used to protect privacy, as well as the ways in which claims to privacy can provide the latitude to lie. In their attempts to maintain their own privacy and their secrets, people can be assisted by others who overlook their lies. Habits of honoring other people's verbal and nonverbal claims about themselves, even when they are not totally convincing, and expectations of similar indulgences from others can keep interactions from getting derailed by small interpersonal bumps. But they also enable exploitation in the form of frauds and scams .
