与信用期限相关的两阶段延期支付下的供应链协调决策

为研究延期支付对供应链企业的影响，在由制造商向零售商提供融资(延期支付）、零售商向消费者提供信用支付构成的两阶段延期支付供应链的基础上，综合考虑延期支付下需求量增加和资金占用成本因素.假设市场需求为延期支付期限的函数.在分散决策下分别给出使制造商和零售商利润最大化的最优延期支付期限和订购数量.在集中决策下给出使供应链总利润最大化的最优延期支付期限和最优生产数量，并比较分析得出，供应链协调时制造商允许零售商延期支付期限的取值范围,实现分散决策下的供应链总利润达到集中决策下的供应链总利润.数值分析表明，延期支付机制可以有效解决供应链成员企业资金短缺问题和实现供应链协调.     

在商业信用下考虑破产风险的供应链协调机制

为了探究在存在破产风险的二级供应链中供应商信用合同采购策略,构建在商业信用和商业贷款两种模式下一体化供应链和非一体化供应链的最优决策模型,并在决策时考虑因破产风险而导致的期望损失,分别采用集中决策的采购策略和收益共享的思想协调非一体化供应链。供应商通过调整施加给零售商的风险溢价和分销价格影响零售商订购行为。数值试验结果表明,在不同运作模式下采用不同的协调方式不仅可以实现供应链成员利润双赢,还能提高整个供应链系统的订购量。     

生产成本可变的两级供应链协调模型

为实现生产商利润最大化和供应链系统完美协调,针对由单一生产商和单一零售商构成的两级供应链系统,在确定市场需求和产品生产成本受生产能力影响的情况下,研究作为Stackelberg博弈主导方的生产商如何利用批量折扣机制来激励零售商合作,从而改善供应链协调性问题.给出作为理性Stackelberg的主导者,生产商如何提供批量折扣契约的一类生产成本可变的两级供应链协调模型,以实现自身利润最大和供应链系统的完美协调,并通过算例进行验证.理论分析结果和数值实验结果都表明该折扣模型对改善供需双方绩效和供应链运作协调十分有效.     

闭环供应链中回收价格变化的回收渠道选择问题

研究了闭环供应链中回收渠道选择问题,建立并求解了回收率随回收价格变动的单一制造商和单一零售商的最优利润模型．引入初始投入系数,以区分不同供应链成员建立回收通道的难易程度．通过案例分析,给出了不同情况下回收渠道选择策略．     

基于消费者补贴的多产品供应链碳减排和价格决策

为研究政府补贴消费者情况下的多产品供应链碳减排优化,考虑由一个制造商和一个零售商构成的多产品两级供应链(制造商处于主导地位),运用Stackelberg博弈理论分别构建制造商和零售商在无政府补贴和政府补贴消费者时的分散决策博弈模型,求解得到最优碳减排率、批发价和零售价。通过比较和分析发现:当政府补贴因子超过一定值时,供应链利润、低碳产品零售价和减排率均优于无政府补贴情形;政府补贴因子和减排难度的变化对制造商、零售商和供应链利润有不同的影响,政府补贴因子的增加和减排难度的降低会促进供应链利润的增加和碳减排率的提高。通过算例分析验证模型的有效性。     

物流服务商管理库存下的供应链三方合同

为建立起物流服务商管理库存(Logistics-service-supplier Managed Inventory,LMI)下供应链三方长期共赢的合作方式,总结归纳出LMI模式.在LMI模式下,在由单一制造商、单一物流服务商和单一零售商组成的三级供应链中,三方对补货方式中的库存量最小值和库存量最大值进行谈判,找到合适的库存量最小值和库存量最大值,使供应链总体利润和各方利润最优.结果发现,供应链成员中谈判能力较强的一方可能更愿意使用LMI模式.这可为制造企业下游库存外包提供决策依据和方法指导.     

网上直销渠道的动态投资对供应商及零售商策略选择的影响

为研究网上直销商与传统供应商之间的竞争,建立可分析供应商对网上直销动态投资策略对供应链影响的供应商、网上直销渠道和传统零售商竞争的微分博弈模型.经过系统动力学模拟,得出供应商和零售商的最优策略.通过不开设和开设网上直销渠道2种情况下供应商利润总和的对比表明:开设网上直销渠道可以改变供应商和零售商的竞争模式,加强零售市场的差异化竞争程度,进而增加供应商的利润;而生产成本和需求弹性较低的商品更适合网上直销.     

港口供应链利益共享契约的协调机制

鉴于港口供应链存在特殊性,以及实际供应链中港口业务服务商的资源没有得到充分利用,影响了港口功能的发挥和供应链整体及各方的利益,考虑一个由港口业务服务商与港口企业组成的二级港口供应链,建立博弈模型.运用利益共享契约作为协调机制,分别分析港口物流服务需求具有和不具有价格敏感性两种情况下的博弈均衡.结果显示,利益共享契约在这两种情况下均可达到Pareto改进,实现港口供应链的利益协调.     

供应链生产系统信息共享的经济分析及实现途径

从运营的角度看,供应链由生产系统、消费系统、社会系统与环境系统四个子系统组成。为了提高每个企业的竞争能力和经济效益,有必要实现整个供应链的信,息共享。从生产系统内成员间信息共享的博弈分析可知,供应链生产系统内信息共享的实现可以提高整个供应链的利润水平。这就涉及到企业战略联盟中的信任问题．信息共享成本的合理分摊和额外利润的合理分配,信息共享与企业自身的商业秘密等诸多问题。这就要求生产系统内成员间信息共享的技术做到：操作交互性,操作安全性,配置动态化,技术标准化。     

考虑物流服务水平影响的三级物流服务供应链协调

为实现物流服务供应链(Logistics Service Supply Chain,LSSC)整体利润的最大化,研究一个由物流服务集成商、物流服务提供商和功能型物流服务分包商组成的三级LSSC的协调问题.在考虑物流服务水平影响市场需求的情况下,建立以物流服务集成商为主导的Stackelberg博弈模型,提出一个由期权契约和成本共担收益共享契约组成的联合契约协调机制,即在LSSC的两个交易过程中,物流服务集成商与提供商之间采用期权契约协调,物流服务提供商与分包商之间执行成本共担收益共享契约.通过契约参数的合理选择实现LSSC最大收益和各成员共赢.通过均匀分布随机环境下的算例分析,验证契约机制的可行性和有效性.     

Cross Culture Communication——in Our Daily Life

Since the late 1960s,culture has been considered tighter with communication.Culture IS based on the community of communication.Communication involves people and their environment.Thus culture is an important factor in communication.Today with modem economic and technological development,intercultural communication is mole important than ever before. When people from different cultural background communicate with each other,their social stereotype pattern of behavior, their habits of language and thought differ from one another,because these are the possible factors that affect intercultural communications.Culture norms also change,culture may be transferred as signs but we have to study and understand the above carefially.

Using Context Clue in Reading

The context of a word consists of the other words surrounding it and the situation in which it is used.When we come across a new word in our reading,instead of looking it up in a dictionary for its definition,we can guess its meaning from its context.     

痛定思痛：当代中国武术发展之缺失——刍议武术所缺乏宽容态度、自省精神、固守品质、稳定情感、真正说教与现代反思

当代中国武术经历了时代的沧桑和变迁,在历经了文化和历史的发展与洗礼之后,依然发展、繁衍至今。在这样一个漫长的过程中,伴随着以社会环境和社会人群价值取向为主的变迁与变化,当代中国武术的发展与当代社会的发展正逐渐的呈现出某些相背离和不和谐的表象。通过研究,我们发觉中国武术中原本一些内在的东西正在不断的被遗忘,正在不断的流逝。本文试从中国武术在当代发展中的问题境域入手,解读中国武术在当今世界和社会中存在的一些问题,希望能够从中找到中国武术发展的＂合法性＂或＂合时性＂的内在依据,以挺立中国武术的脊梁。
