物流一词源于英文的”logistics”,原意是军事后勤保障,在第二方世界大战以后被广泛地应用于经济领域。美国物流管理协会对物流的定义为”物流是为满足消费者需求而进行的对原材料、中间产品、最终产品及相关信息从起始地到消费地的有效流动与存储的、实施和控制的过程”。
物流由四个关键部分组成:实质流动、实质存储、信息流动及管理协调。物流的主要功能是创造时间效用和空间效用,主要方式是通过仓储克服空间距离。
第三方物流是在物流渠道中由中间商提供的服务,中间商以合同的形式在一定期限内提供需的全部或部分物流服务。第三方物流公司是一个为外部客户管理、控制和提供物流服务作业的公司。
据统计,欧洲目前使用第三方物流服务的比例为76%,美国约为58%,且其需求仍在增长;欧洲24%和美国33%的非第三方物流服务用户正在积极考虑使用第三方物流服务。第三方物流作为一个提高物资流通速度、节省仓储费用和资金在途费用的有效手段,已经越来越引起人们的高度重视。
一、使用第三方物流的优越性
使用第三方物流产可以给企业带来众多益处,主要表现在:
1、集中主业
生产企业使用第三方物流可以使企业实现资源的优化配置,将有限的人力、财力集中于核心精力,进行重点研究,发展基本技术,开发新产品参与世界竞争,增强企业的核心竞争力。
2、节省费用
专业的第三方物流提供者利用规模生产的专业优势和成本优势,通过提供各环节能力的利用率实现费用节省,使企业能从分离费用结构中获益。生产企业随着规模的不断扩大,对营销服务的任何程度的深入参与,都会引起费用的大幅度增长,只有使用专业服务公司提供的公共服务,才能够减少额外损失。根据美国田纳西大学、英国EXEL公司和美国EMST&YOUNG咨询公司共同组织的一项调查显示:很多货主表示,使用第三方物流使他们的物流成本平均下降了1.18%,货物周转期平均从7.1天缩短到3.9天,库存降低了8.2%。
3、减少库存
第三方物流服务提供者借助精心策划的物流和适时的运送手段,最大限度地减少库存,改善了企业的现金流量,实现成本优势。
4、提升企业形象
第三方物流服务提供与顾客是一种战略伙伴关系,第三方物流提供者利用完备的设施和训练有素的员工对整个供应链实现完全的控制,减少物流的复杂性,通过自己的网络体系帮助顾客改进服务,不仅树立自己的品牌形象,而且使顾客在竞争中脱颖而出。
二、我国企业在使用第三方物流方面存在的问题
尽管与第三方物流公司合作有很多优势,但是很多企业并不是将更多的物流业务外包出去,原因归结为:
1、抵制变化
很多公司不愿意通过物流外包的方式来改变现在的精力模式。尤其是一些国有企业,物
流业务外包还将意味着解雇大批员工,这对于国有企业的管理者来说意味着一个非常大的风险。
2、缺乏认识
企业对于第三方物流公司的认识程度普遍还很低,企业没有认识到供应链管理在企业竞争中的巨大作用。
3、害怕失去控制
由于供应链的实施在提高公司竞争力方面的重要作用,很多公司宁愿有一个小而全的物流部门,也不情愿将这些功能交给别人,主要原因是担心如果失去内部物流能力,会在客户交往和其他方面过度依赖第三方物流公司。
4、物流业务外包本身有其复杂性
供应链物流业务通常和公司其他业务,如财务、营销或生产集成在一起,物流业务外包本身就具有复杂性。对一些实际业务,包括运输和仓储的集成可能会带来组织上、行政上和实施上的一系列问题。此外,公司内部信息系统的集成性特点,使得把物流业务交给第三方物流公司来运作变得很困难。
5、衡量物流外包的效果受诸多因素的影响
准确地衡量物流成本对信息技术和人力资源的影响比较困难。很难确定物流业务外包到底能够给企业带来多少潜在的成本好外。另外,各个公司业务的独特性和公司供应链作业能力,通常被认为是不宜向外部公开的内部信息,很难准确地比较公司间的供应链作业能力。
尽管有些生产企业已经意识到利用第三方物流可以给企业带来很多好外,但是在实际应用时往往分成几个步骤,同时选择数个物流服务提供商作为合作伙伴,以避免将业务交由一个物流服务提供商而带来的依赖性。
三、我国第三方物流企业在发展中遇到的问题
一个成功的物流企业,必须具备较大的运营规模,建立有效地地区覆盖区域,具有强大的指挥和控制中心,具备高水准的综合技术、财务资源和经营策略。
我国第三方物流企业在发展中遇到的问题可以归纳如下:
1、运营模式问题
目前世界大型物流公司大都采取总公司与分公司体制,总部采取集权式物流运作,以业务实行垂直管理。建立现代物流企业必须有一个能力很强、指挥灵活的调控中心对整个物流业务进行控制与协调。真正的现代物流必须是一个指挥中心、一个利润中心,企业的组织、框架、体制等形式都要与一个中心相匹配。我国的物流企业在运营模式上存在问题,国外物流企业的管理模式值得国内物流企业借鉴。
2、仓储或运输能力欠缺
物流的主要功能是创造时间盗用和空间效用。就目前中国的第三方物流企业而言,有些公司偏重于仓储,运输能力不足;另外一些公司则是运输车辆很多而在全国没有多少仓库,靠租用社会仓库来完成对客户的承诺。
3、网络问题
我国有几家大的物流企业拥有全车性的仓储网络或货运网络,但是这个网络的覆盖区域并不是十全十美的。客户在选择物流合作伙伴时,很关注网络的覆盖区域及网络网点的密度问题。有关网点的建设问题应引起物流企业的重视。
4、信息技术
世界大的物流企业都拥有”一流三网”,即订单信息流、全球供应链资源网络、全球用户资源网络和计算机信息网络。凭借先进的计算机管理技术,这些物流客户也是高附加值产品的生产企业,国内物流企业必须在信息系统上增加投入才可以改变自己的市场定位。
集中与整合是第三方物流企业的发展趋势。原因是:第一,大的公司有意将供应链的主要环节外包给尽可能少的几家物流公司;第二,建立一个高效的全球第三方物流企业所需资本的投入日益增加;第三,许多第三方物流供应商都通过兼并和联合的方式来扩大其服务能力。
Logistics from the English word "logistics", the original intent of the military logistics support, in the second side after World War II has been widely used in the economic field. Logistics Management Association of the United States is defined as the logistics, "Logistics is to meet the needs of consumers of raw materials, intermediate procts, final procts and related information to the consumer from the beginning to the effective flow and storage, implementation and control of the process of . "
Logistics consists of four key components: the real flow, real storage, and management to coordinate the flow of information. The primary function of logistics is to create time and space effectiveness of the effectiveness of the main ways to overcome the space through the storage distance.
Third-party logistics in the logistics channel services provided by brokers, middlemen in the form of the contract within a certain period of time required to provide logistics services in whole or in part. Is a third-party logistics companies for the external customer management, control and operation of the provision of logistics services company.
According to statistics, currently used in Europe the proportion of third-party logistics services for 76 percent, the United States is about 58%, and the demand is still growing; 24 percent in Europe and the United States 33% of non-third-party logistics service users are actively considering the use of third-party logistics services. As a third-party logistics to improve the speed of material flow, warehousing costs and financial savings in the cost effective means of passers-by, has become increasingly attracted great attention.
First, the advantages of using a third-party logistics
The use of third-party logistics enterprises can yield many benefits, mainly reflected in:
1, focus on core business
Manufacturers can use a third-party logistics companies to achieve optimal distribution of resources, limited human and financial resources to concentrate on their core energy, to focus on the development of basic skills, develop new procts in the world competition, and enhance the core competitiveness of enterprises.
2, cost-saving
Professional use of third-party logistics providers, the professional advantages of mass proction and cost advantages, by providing the link capacity utilization to achieve cost savings, so that enterprises can benefit from the separation of the cost structure. Manufacturing enterprises with the expansion of marketing services to participate in any degree of depth, would give rise to a substantial increase in costs, only the use of professional services provided by public services, in order to minimize additional losses. University of Tennessee in accordance with the United States, United Kingdom and the United States EXEL company EMST & YOUNG consulting firm co-organized a survey: a lot of cargo that enable them to use third-party logistics logistics costs declined by an average of 1.18 percent, the average flow of goods from 7.1 days to 3.9 days, stock 8.2% lower.
3, rection of inventory
Third-party logistics service providers with well-planned logistics and timely delivery means, to minimize inventory, improve cash flow of the enterprise to achieve cost advantages.
4, enhance the corporate image
Third-party logistics service providers and customers is a strategic partnership, the use of third-party logistics provider of comprehensive facilities and trained staff on the whole supply chain to achieve complete control, recing the complexity of logistics, through their own networks to help improve customer service, not only to establish their own brand image, but also customers in the competition.
Second, China's enterprises in the use of third-party logistics problems in
While third-party logistics company has many advantages, but not many enterprises will be more outsourcing of the logistics business, the reasons boil down to:
1, resistance to change
Many companies do not want the way through the logistics outsourcing efforts to change the current mode. In particular, some state-owned enterprises, were
Flow will also mean that the dismissal of outsourcing a large number of employees, which the managers of state-owned enterprises would mean a very great risk.
2, lack of awareness
For third-party logistics enterprise's generally low level of awareness, lack of awareness of enterprise supply chain management in the enterprise of the great role in the competition.
3, fear of losing control
As a result of the implementation of supply chain companies in enhancing the competitiveness of the important role that many companies would rather have a small but complete logistics department and they do not prefer these functions will be handed over to others, the main reasons it is worried that if they lose the internal logistics capabilities, customers will be exchanges and over-reliance on other third-party logistics companies.
4, the logistics outsourcing has its own complexity
Supply chain logistics business and companies are usually other services, such as finance, marketing or proction of integrated logistics outsourcing itself with complexity. On a number of practical business, including the integration of transport and storage may lead to organizational, administrative and implementation problems. In addition, the company's internal information system integration features, making the logistics business to a third party logistics companies have become very difficult to operate.
5, to measure the effect of logistics outsourcing by many factors
Accurately measure the cost of information technology, logistics and human resources more difficult. It is difficult to determine the logistics outsourcing companies in the end be able to bring the cost of how many potential good things. In addition, all the uniqueness of the company's business and corporate supply chain operational capability, is usually not considered to be internal to the external public information, it is difficult to accurately compare the inter-company supply chain operational capability.
Although some manufacturers have been aware of the use of third-party logistics companies can bring a lot of good things, but in practical applications are often divided into several steps, at the same time choose a number of logistics service providers as partners in order to avoid the business by a logistics service providers brought about by dependence.
Third, China's third-party logistics companies in the development of the problems encountered
A successful logistics company, the operator must have a larger scale, the establishment of effective regional coverage area, with a strong command and control center with the high standard of integrated technical, financial resources and business strategy.
China's third-party logistics companies in the development of the problems encountered can be summarized as follows:
1, operating model
At present, most of the world's largest logistics companies take the head office and branch system, centralized headquarters-style logistics operation to take to the implementation of vertical business management. The establishment of a modern logistics enterprise must have a strong, flexible command and control center to control the entire logistics operations and coordination. Real must be a modern logistics center, a profit center, business organizations, the framework, the institutional form of every match with a center. China's logistics enterprises in the operating mode of the problems of foreign logistics enterprises in the management model should be from the domestic logistics enterprises.
2, the lack of storage or transport capacity
The primary function of logistics is to create time and space utility theft. For now China's third-party logistics enterprises, some companies focus on storage, lack of transport capacity; other companies is a lot of transport vehicles and warehouses throughout the country little by renting warehouses to complete the community's commitment to customers.
3, network problems
There are a few large companies have the logistics of the entire vehicle cargo storage network or networks, but the network coverage area is not perfect. Customers in the choice of logistics partner, are very concerned about network coverage and network of regional branches of the density problem. The building of the network should be of great importance to logistics enterprises.
4, information technology
The world's largest logistics enterprises have "three-class network", that is, orders for information flow, resources, global supply chain network, the global Resource Network users and computer information network. With the management of advanced computer technology, these customers are also the logistics of the proction of high value-added procts business, the domestic logistics enterprises must increase investment in information systems can change their market position.
Concentration and integration is the third-party logistics trends in the development of enterprises. The reasons are: firstly, the company intends to major aspects of supply chain outsourcing to the lowest possible number of several logistics companies; the second, the establishment of an efficient global third party logistics inputs required for increasing the capital; the third Many third-party logistics providers through mergers and joint approaches to expand its service capabilities.

Abstract
A method is presented to predict the complete stress–strain curve of concrete subjected to triaxial compressive stresses caused by axial load plus lateral pressure e to the confinement action in circular, box and octagonal shaped concrete-filled steel tubes. Available empirical formulas are adopted to determine the lateral pressure exerted on concrete in circular concrete-filled steel columns. To evaluate the lateral pressure exerted on the concrete in box and octagonal shaped columns, FEM analysis is adopted with the help of a concrete–steel interaction model. Subsequently, an extensive parametric study is concted to propose an empirical
equation for the maximum average lateral pressure, which depends on the material and geometric properties of the columns. Lateral pressure so calculated is correlated to confined concrete strength through a well known empirical formula. For determination of the post-peak stress–strain relation, available experimental results are used. Based on the test results, approximated expressions to predict the slope of the descending branch and the strain at sustained concrete strength are derived for the confined concrete in columns having each type of sectional shapes. The predicted concrete strength and post-peak behavior are found to exhibit good
agreement with the test results within the accepted limits. The proposed model is intended to be used in fiber analysis involving beam–column elements in order to establish an ultimate state prediction criterion for concrete-filled steel columns designed as earthquake resisting structures. •2001 Elsevier Science Ltd.

1. Introction
Concrete-filled steel tubes (CFT) are becoming increasingly popular in recent decades e to their excellent earthquake resisting characteristics such as high ctility and improved strength. As a result, numerous experimental investigations have been carried out in recent years to examine the overall performance of CFT columns [1–11]. Although the behavior of CFT columns has been extensively examined, the concrete core confinement is not yet well understood. Many of the previous research works have been mainly focused on investigating the performance of CFT columns with various limitations. The main variables subjected to such limitations were the concrete strength, plate width-to- thickness (or radius-to-thickness) ratios and shapes of the sections. Steel strength, column slenderness ratio and rate of loading were also additionally considered. It is understandable that examination of the effects of all the above factors on performances of CFTs in a wider range, exclusively on experimental manner, is difficult and costly. This can be overcome by following a suitable numerical theoretical approach which is capable of handling many experimentally unmanageable situations. At present, finite element analysis (FEM) is considered as the most powerful and accurate tool to simulate the actual behavior of structures. The accurate constitutive relationships for materials are essential for reliable results when such analysis proceres are involved. For example, CFT behavior may well be investigated through a suitable FEM analysis procere, provided that appropriate steel and concrete material models are available. One of the simplest yet powerful techniques for the examination of CFTs is fiber analysis. In this procere the cross section is discretized into many small regions where a uniaxial constitutive relationship of either concrete or steel is assigned. This type of analysis can be employed to predict the load–displacement relationships of CFT columns designed as earthquake resisting structures. The accuracy involved with the fiber analysis is found to be quite satisfactory with respect to the practical design purposes.
At present, an accurate stress–strain relationship for steel, which is readily applicable in the fiber analysis, is currently available [12]. However, in the case of concrete, only a few models that are suited for such analysis can be found [3,8,9]. Among them, in Tomii and Sakino’s model [3], which is applicable to square shaped columns, the strength improvement e to confinement has been neglected. Tang et al. [8] developed a model for circular tubes by taking into account the effect of geometry and material properties on strength enhancement as well as the post-peak behavior. Watanabe et al. [9] concted model tests to determine a stress–strain relationship for confined concrete and subsequently proposed a method to analyze the ultimate behavior of concrete-filled box columns considering local buckling of component plates and initial imperfections. Among the other recent investigations, the work done by Schneider [10] investigated the effect of steel tube shape and wall thickness on the ultimate strength of the composite columns. El-Tawil and Deierlein [11] reviewed and evaluated the concrete encased composite design provisions of the American Concrete Institute Code (ACI 318) [13], the AISC-LRFD Specifications [14] and the AISC Seismic Provisions [15], based on fiber section analyses considering the inelastic behavior of steel and concrete.
In this study, an analytical approach based on the existing experimental results is attempted to determine a complete uniaxial stress–strain law for confined concrete in relatively thick-walled CFT columns. The primary objective of the proposed stress–strain model is its application in fiber analysis to investigate the inelastic behavior of CFT columns in compression or combined compression and bending. Such analyses are useful in establishing rational strength and ctility prediction proceres of seismic resisting structures. Three types of sectional shapes such as circular, box and octagonal are considered. A concrete–steel interaction model is employed to estimate the lateral pressure on concrete. Then, the maximum lateral pressure is correlated to the strength of confined concrete through an empirical formula. A method based on the results of fiber analysis using assumed concrete models is adopted to calibrate the post-peak behavior of the proposed model. Finally, the complete axial load–average axial strain curves obtained through the fiber analysis using the newly proposed material model are compared with the test results. It should be noted that a similar type of interaction model as used in this study has been adopted by Nishiyama et al. [16], which has been combined with a so called peak load condition line in order to determine the maximum lateral pressure on reinforced concrete columns.
Meanwhile, previous researches [17,18] indicate that the stress–strain relationship of concrete under compressive load histories proces an envelope curve identical to the stress–strain curve obtained under monotonic loading. Therefore, in further studies, the proposed confined uniaxial stress–strain law can be extended to a cyclic stress–strain relationship of confined concrete by including a suitable unloading/reloading stress–strain rule.

(7) papers, endnotes or conclusions should write clearly the conclusion of the paper reliable results, the conclusions. Write conclusive The paper should be concise, can literally text. Do not use "summary" ambiguous word. (8) papers - this is offering reference righteousness is an important papers, and existing problems of more. The paper lists reference purpose is to let the reader know the ins and outs of research propositions for search, also respect the previous work, for his work is accurate positioning. So here are both technical problems, and scientific moral problems. An essay in almost all necessary throughout the reference. This introction should be led to ontology is the most important and directly relevant literature, In the method should be adopted in the owner or reference method, Sometimes in the literature of the owner to comparative data, In discussions with the relevant papers should be led all kinds of support or conflicting results or views. All carelessness, don't check literature, Intentionally don't lead, itself, innovation, To tease others overinflate, The trivial, posturings practices are wrong. This phenomenon is now in many papers or see somewhat, it should be considered as the big fear the research workers. Among them, don't find missing important documents and literature, intentionally don't lead others denouncing others work or documents such mistakes is more apparent, easy to find. Some methods are compared, such as the lead concealed in the introction, it led to the discussion. It was originally you be the basis for an essay or put your papers, and the position of the second-best. And as research work is graally deep development, your work is always in the previous work on the foundation of the development. The correct method, this should be made to the subject, what this person in this basis and made what results in them, now I completed this based on a research. This is the realistic manner, this statement harming your contribution. Some of the papers, authors did not say so, but this did not make someone this term, and done ontology is someone without, I now. It is not realistic manner. So sometimes can deceive some unknown, but just outside the truth is a paper tiger chuo, professional, the reputation. Outsmart oneself, This kind of phenomenon in real life or not. (9) papers - thanks to the thesis guides, and provide special agents or equipment, sponsors and raised funds thanks all belong to an important proponent. Papers should be sincere thanks, true of, don't vulgar. Don't thank broadly, not only professor xie xie others don't. Thanks for essay before the agreed to be thanked LaDaQi, cannot ZuoHuPi. (10) -- the papers in 200 words or abstract: briefly summarized about full papers. Always put this paper. The paper should carefully compose and attractive. Let the reader looked like see the epitome of the paper, or see the paper will continue to see the relevant papers. In addition, still should give a few words, keywords should write the real key to academic vocabulary, don't YingCou general terms.

例如,简支梁桥图。 9月2日(一)可
所代表的集中质量
第53页
模型图。 2.9 ( b )项。所有结构有一些固有频率时,他们往往
震动。如果大桥图。 2.9很高兴,风,也就是说,它可能震动以下
频率所示,图。 2月10日。形状的结构振动是在这样的
被称为模式形状。
最简单形式的动态分析,源的励磁桥不是
认为,只有自然频率和振型决心。如果可以
结果表明,自然频率的桥梁不能接近的频率的所有预期
来源激励,可能是没有必要进一步动态分析。常见形式
激励卡车振动,风,慢跑或散步的行人。即使
频率不紧密,往往会是如此的公路桥兴奋交通,
突然载荷产生显着更多的压力比静态应用之一。
然而,等效静荷载中指定的实务守则考虑到这一
现象,并纳入动态放大因子。可以动态放大
定义为比率的实际应力,由于相应的静态负荷。
如果激励频率接近一个自然频率的桥梁,进一步
分析必须确定动态扩增什么是所谓的'强迫
振动分析。在这样的分析,互动
图。 2.9 Idealisation梁的动态分析: (一)原梁; (二)集中质量模型
图。 2月10日模态的简支梁: (一)典型的第一振型; (二)典型的第二
模式形成

适用于装载和桥梁考虑。在道路交通,应用
装货的卡车或货车相当大,振动自己的轮胎和悬挂。
此外,卡车正在做的位置,他们的人民群众是随时间变化。
这种分析是目前唯一可能与专业的计算机程序,
把复杂的卡车摇晃,弹跳运动和变化
卡车动态特性可预期的典型交通。
在第2.5节,设计的影响,车辆碰撞桥梁进行了讨论。为了
这种情况下,该草案规定了相当于欧洲规范静力。作为一种替代办法,代码
可进行动态分析。在这种情况下,相当于武力
假定以增加从零到其全部价值在很短的时间内(以
毫秒) ,并保持恒定值为进一步短的时间内(该命令的200毫秒) 。
这种载入中可以很容易地指明了一个计算机模型和最大分布

⑥ 跪求道路设计方面的英文文献+翻译。没有翻译也可以。大概3000字左右
每个大学都是购买了电子文献的,你要不是不用了话就亏了!现在告诉版你怎么找文献:登权陆你们学校图书馆网站(必须是你们学校的校园网),找到“外文文献”(可能各学校名字不一样,大概就这个意思),点击进入,里面可能会有很多电子图书期刊的索引,你找道路方面的就可以,或有的是适合全校各学院的,网站上一般有说明,然后点击进入,之后就想用网络一样了,输入你的关键字、题目或作者,就可以找到很多这方面的文献了!说的不是很清楚,你自己摸索下吧,很简单的!其实一般大学入学的时候应该会有一个图书馆的培训的! 码字很累,谢谢采纳。
⑦ 想要路桥毕业设计英文翻译或者是二建音频教材的可以联系我,留下邮箱抽空给你们发过去。。。
现在路桥也用英语了 接轨了
