The Study on Sensing Technology for Cognitive Radio

随着软件无线电技术的发展和认知无线电概念的提出，人们已经认识到认知无线电技术是当前技术条件下解决无线频谱利用率低的最佳方案之一。频谱感知技术是认知无线电中最基本和最关键的技术，因此实现快速而准确地搜索可用频谱，为认知无线电其他关键技术的研究奠定坚实的基础。认知无线电网络，相对于传统无线网络，会面临一些新的安全隐患，比如冒充主用户信号的攻击（PUE攻击）等，一个网络能否得到广泛应用，它的安全性成为一个重要的因素，因此研究认知无线电的安全问题对认知无线电的应用有着重要的意义。 当前存在的几种频谱感知技术，都不能同时兼顾到感知的准确性和有效性。本文的研究内容之一就是对现有频谱感知方法进行改进，将W...With the development of software radio and the proposed concept of cognitive radio (CR), it is recognized that CR technology is one of the best options for solving the problem of low spectrum utilization.

The Dual-channel Pricing Decision-making and Quality Information Disclosure under the Information Asymmetry

探讨了质量信息不对称下制造商与零售商联合披露、制造商披露以及零售商披露3种披露方式下的双渠道定价策略,得到不同披露方式下的质量信息披露条件。结果表明:3种披露方式下的质量信息披露阈值都与披露成本、交叉价格弹性、渠道的潜在需求量相关,且披露成本越大,质量披露的动机就越小。同时借助于数值分析发现,当产品质量较低或较高时,零售商披露方式最优;当产品质量中等时,制造商披露要相对优于零售商披露,但只有联合披露可以使双渠道供应链系统达到最优状态。Under the information a symmetry of product quality,this paper discusses three quality information disclosure strategies： joint disclosure between the manufacturer and retailer,manufacturer disclosure and retailer disclosure and the pricing strategy of the dual channel. And the conditions to disclose the product quality under different quality information disclosure strategies are analyzed. Our conclusions show that the quality disclosure threshold under three disclosure formats related to disclosure cost,potential demand and the cross price elasticity,and the higher disclosure cost,the less motivation to disclosure quality. Finally,by using the numerical analysis,the obtained results show that when the product quality is low or high,it is better to adopt retailer disclosure; when product quality is medium,manufacturer disclosure is relatively better than retailer disclosure,but joint disclosure can make dual channel supply chain system reach the optimal state.国家自然科学基金项目(71571151、71371159)

Study on Tobacco- Leaf Inventory Management Strategy Based on Revenues Sharing Mechanism

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。Based on the background of integrated- logistics of cigarette and tobacco leaf in Fujian province,this paper builds a model revealing revenue sharing mechanism on tobacco- leaf inventory management strategy.Then Shapley value method is adopted to determine the revenue sharing proportion,risk factor is introduced to fix distribution of profit between Tobacco Logistics Company and redrying factory,and this paper's discussion will show revenue sharing ratio is influenced by the coefficient of inventory integration ability,the risk of Logistics Company and inventory cost of tobacco leaf accounts for the ratio of the total cost of redrying factory.On this basis,using the numerical analysis demonstrates the feasibility of this method.The analysis results show that the coefficient,the risk and the ratio is proportional to the revenue- sharing ratio,Shapley value method with risk factors is more reasonable for distribution of profit between tobacco logistics company and redrying factory.中国烟草总公司福建省公司“两烟物流一体化运行模式研究与实践”项目; 国家自然科学基金项目(71371159); 浙江省科技厅软科学研究计划(2014C35018
