Multi-Agent供应链信息共享协调机制研究——以中兴供应链为例

在供应链中牛鞭效应是不可避免的,信息流的传递总会发生或多或少的扭曲失真,但是各供应链成员通过信息共享能够有效地抑制牛鞭效应.通过分析深圳市中兴通讯股份有限公司为核心企业的多代理(Multi-Agent)供应链,结合牛鞭效应成因、影响和控制,对信息共享内容和协调模式进行研究,构建合理的信息共享模式以提高信息共享的程度,从而达到弱化牛鞭效应,提高整个供应链的运作效率.     

供应链运作中的时间压缩策略分析

为了提高供应链的市场竞争能力,本文从供应链的两条提前渠道———物流和信息流的传递渠道,分析供应链运作中的时间压缩策略。基于史蒂芬纽的研究成果,物流的时间压缩从以下三个方面进行分析:企业供应链、产品供应链、供应链合作伙伴关系。信息流的时间压缩通过信息共享和人员培训两种途径来进行。并指出:物流和信息流的时间压缩是并立而行的,只有两者的密切合作才能使全部循环时间达到最小。     

基于企业整体模型的供应链信息流研究

针对推拉驱动模式供应链驱动力的变化,在总结相关文献的基础上,构建了推拉驱动模式供应链信息整合能力测度的模糊综合评价指标体系,从物理设施、信息流程与信息内容、信息组织结构、信息用户体验与满意、供应链整体效益5个方面,结合实际调研资料,对种业供应链(A)与家电行业供应链(B)的信息整合能力进行了模糊综合评价.测度结果表明,所得出的量化指标符合测度对象信息整合能力的实际水平,对供应链运营策略的调整及运营绩效的提高能够起到积极的推进作用.     

供应链管理中的价值波动

企业供应链管理中信息流的传递存在着大量的不确定性和复杂性,由于信息传递的误差,供应链各级成员的订货量有逐渐增大的趋势,而其变化规律并不能真实反映市场需求的变化规律,引起这种信息失真的原因是多方面的,其中供应链管理者在供应链各基础组织中的行为是一个重要方面,本文从理论上分析了价格波动对供应链信息失真所造成的影响,并提出了一些解决对策。     

供应链信息共享度的模糊评价研究

供应链节点企业间的信息共享度对减缓供应链牛鞭效应、提高供应链运作效率有着重要的影响.在整合目前关于供应链信息共享度研究文献的基础上,构建了供应链信息共享度评价指标体系,并依据所建立的评价指标体系,结合实际企业运行数据,对供应链信息共享度进行了模糊综合评价.     

供应链协同绩效评价及其应用

在对供应链协同及绩效评价相关文献综述的基础上,考虑供应链管理中的信息流、业务流、资金流,并结合客户服务和系统适应性,选择了23个供应链协同评价指标,建立协同绩效评价指标体系.然后,以一食品公司为例,运用模糊综合分析法对其供应链进行协同评价,实现了对该指标体系的量化,并对评价结果进行分析.结果表明,企业在信息流、业务流、资金流、客户服务和系统适应性方面协同运作,可以提高供应链整体的运作绩效,从而进一步验证了评价指标体系的可行性和模糊综合评价方法的可操作性.最后,指出了供应链协同绩效评价的发展方向.     

面向供应链管理的行业信息系统问题域对象建模

基于供应链管理的结构模型和信息流传递模型,提出了一种行业信息系统问题域对象的建模方法.依照供应链的网络结构模型进行问题域的类结构设计,从供应链网络结构模型中的事物抽象出行业信息系统中的问题域类;依照供应链的集中式信息流传递模型进行问题域类的行为设计,将供应链信息流传递模型中的传递行为抽象为问题域的类行为.由此得出行业信息系统的问题域类结构模型和行为模型,并在一个实际应用系统中实现了该模型.     

供应链信息共享的激励问题研究

随着科学技术的不断提高,顾客的多元化、个性化需求向传统的管理模式提出了严峻的考验,供应链逐步发展成为了全球化市场竞争的核心。供应链是物流、资金流和信息流的统一体,而物流、资金流的展开都紧密围绕着信息流。为了使供应商、制造商、分销商、零售商能各司其职,充分发挥各自的优势,实现整个供应链的一体化发展,提高供应链的效率,降低成本,激励供应链各节点企业进行信息共享显得尤为重要。     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the     

An affordable accurate evaluation of the binding conformations predicted by molecular docking studies in bio-system

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of
