Key-Words: - Supply chain management; Information technology; Support System; Information flow; Supply chain; Information

1 Introduction

Supply Chain Management (SCM) rise is attributed to enterprises trying to eliminate production and inventory plans misleading as information slow transmission or errors. In 1990s, some of computer manufacturers such as HP, or P & G which product household appliances begin integrate information systems of down-upstream, hope to archieve purposes for rapid responsion to the demand of market and lower inventory by correct and rapid transmission, analysis and integration of information. Therefore, effective supply chain management is built on the basis of the high quality of information transmission and sharing, This will rely heavily on information technology to provide reliable support.

In today's age, information has become a key factor in the decision to the survival and development of enterprises, any business must face the issue of how to integrate information. Information is from both the vertical information of the upstream and downstream firms and the horizontal information of the internal enterprise, as well as

information of the macro level. How to transmit and share information, to coordinate economic behavior of the upstream and downstream enterprises and functional behavior of interal enterprise which is the core questions supply chain management is to deal with. Compared with the individual enterprises, supply chain as an extended enterprise, shows own characteristics by its way of information flow and acquisition.

2 The Characteristics of the Supply Chain Information Flow

2.1 Wide coverage

The information of the supply chain covers from all links of suppliers, manufacturers to distributors and then retailers in the supply chain. Information flow distinct into information flow of demand and supply, these are two different flows of information flow. When demand information (such as customer orders, production planning, procurement, etc.) takes direction from the demand-side to the supply-side movement, it triggered logistics. Meanwhile supply information (such as storage lists, the inventory records for sales, deliver lists), together again along with materials for the direction of the supply chain from supply-side to demand-side movement. The information flow of individual enterprises mainly confined to the internal Invoicing records (see figure 1).

2.2 More access channels

As businesses in the supply chain is a collaboration relationship and community interests, information of the supply chain have so many channels to obtain. demand information isn’t only from the customers but also distributors and retailers; the supply Information is from various suppliers, These information flow and share in all enterprises through the supply chain information systems . For individual enterprises,

as it haven’t formed the Community interests with upstream and downstream businesses, so it is totally dependent on own collection.

2.3 High-quality information

Because of specialization, the quality of the supply chain was superior to the information of the single enterprise, For example, distributors and retailers can be specifically responsible for the collection of demond information, the suppliers will collect supply information, Product manufacturers collect information of products.

3 Information Technology and Supply Chain Management

The development of information technology provides an effective support to supply chain management. About some issues how to thank of the impact of information technology on supply chain management, and how to use information technology in supply chain management, and so on, through studies, it basically can be summed up in three aspects :

3.1Enhance the sharing of information on the supply chain can effectively improve supply chain management

When members of the supply chain based only on information from neighbor member of lower levels to make decision, the system will have a phenomenon of magnification of demand. The reason for this situation is not the irrational of all members, but rational decision-making in the actual circumstances of unclear information, included demand forecast in the unbalanced demand, increasing orders in the expected shortage, increasing EOQ for the fixed orders costs and effects of batch. The occurrence of this phenomenon will have a negative impact on all members of the supply chain. To eliminate or contain this phenomenon, within the scope of the supply chain, we can take appropriate countermeasures, such as to strengthen information sharing, shorten the delay time, coordinate purchasing and simplify marketing behavior and so on.

3.2 The development of information technology enhances internal collaboration in the supply chain

The development of information technology makes enterprises more accessible to use information technology to exchange and collaborate with other members of and

supply chain, therefore the use costs relatively lower, so that enterprises can choose more supplies to get cheaper supply and services in the same level of information use costs. In other words, the relationship between enterprises and their suppliers will likely become unreliable and unstable, but the number of suppliers which successful enterprises choose don’t increase, but reduce. In fact, "between enterprises and their suppliers and customers, it is necessary to establish a collaborative relationship" that it has a clear requirement in the JIT, it just has not been given sufficient attention.

3.3 The development of information technology can help to build a more perfect user demand model

The end-user is an important component of the supply chain, the response situation to customer demand is a very important supply chain management evaluation. Better graspping the demands of users is the basis of supply chain management. Many articles used similar assumption for a variety of needs and distribution, but demand is random, its release is not as ideal as we generally assumed. Therefore, it is necessary to consider the demand forecast in the supply chain inventorycontrol problems, choose different model according to different circumstances, establish an appropriate demand model.

4 Information Technology Support System of Supply Chain Management

The establishment of the supply chain information systems needs a large number of information technology to support, we discuss information technology support system in the forming of supplychain management from the main areas of supply chain management.

The main areas of supply chain management involved: products (services) design, manufacturing, marketing, customer service, logistics and so on. It is a synchronized, integrated production plan as a guide, through use different types of information technology to improve the performance in these areas (see figure 2).

Information technology to support the supply chain can be divided into two levels.

4.1 The first level

The first level is component with technology of identification code, automatic identification and data collection technology, electronic data interchange technology, Information technology on the basis of Internet technology.

4.1.1 Technology of Identification Codes

A unified information coding is the basis of the exchange and sharing of data among supply chain trading partners. Without it, automatic identification technology and electronic data interchange (EDI) can not be realized. Through standardization technology of information coding applied to the supply chain management system, it is realized that automated data collection in the activities of supply chain systems and exchange of data and sharing ofresources between systems. It can promote the efficient functioning of the supply chain activities.

4.1.2 Automatic Identification and Data Collection Technology

Automatic identification and data collection (AIDC) has become the ideal technology of dealing with the logistics information in process to supply chain management. Through automatic identification technology, automatic data identification and data collection, it is ensured that High-speed and accurate data acquisition and real-time control in the links of supply chain. At present, in the supply chain management, the most commonly AIDC technology is barcode technology and radio frequency

identification technology. Barcode technology can facilitate the timely capture the needs of the consumer, improve sales results, as take placeimmediately automatic retrieval of information in the activities. Barcode alternative keyboard input and improve the accuracy of data collection, the application of technology solve the "bottleneck" problems of the data entry and data collection.

Radio Frequency Identification (RFID) technology is a relatively new automatic identification technology. RFID technology can be characterized as non-contact identification (identification distance from a few centimeters to tens of meters), identification of high-speed moving objects, resistance of harsh environment, secrecy, it can also identify a number of identified targets, therefore widely used in the manufacturing and other unfit barcode labels environment. In the supply chain process control, it was widely used transport vichoel identification (A VI), tracking and monitoring goods, shop alarm systems, expressway toll and intelligent transportation system (ITS), production line automation and process control as well. 4.1.3 Electronic Data Interchange (EDI)

EDI technology is method that transmit and exchange data between different enterprises in order to improve the efficiency of business activities on the basis of standardized data through computer networks. EDI is a essential technology of Replenishment methods of rapid response (QR), Efficient Consumer Response (ECR). At present, almost all of the supply chain management methods of operation without the support of EDI technology. the main functions of EDI performance electronic data transmission and exchange, evidence for transmission data, instruments standard format for data conversion, security, and providing information inquiries, providing technical advisory services, providing the value-added information services. Global 500 biggest enterprises which are selected by the American Fortune magazine have applied their EDI systems with major customers and suppliers to exchange business information.

4.1.4 Internet Technology

The development of Internet technology supplies a the basis tool of relatively, quick and cheap for members of the supply chain to share and exchange information. With

development and mature of wireless Internet technology, the members of supply chain can not be restricted to commercial space activities.

4.2 The Second Level

The second level is component with various information systems and application software whichare developed to support production and various aspects of the management on the basis of information technology infrastructure. When integrated and applicate systems, they not only will be considered to be a technical solution, but also a deep refraction of management thinking should be understand.

4.2.1 Point of Sale System(POS)

POS is system through automated retrieval equipment (cash register) in the direct sale of merchandise sales information retrieval, and then through communication networks and computer systems transmitted to the relevant authorities for analysis to enhance the operating efficiency of the processing.

4.2.2 Electronic Automatic Ordering System (EOS)

EOS refers to use the communication network (V AN or Internet) and the terminal equipment by the means of on-line (ON-LINE) to carry out orders and the exchange of orders information. Compared with traditional methods of ordering, the EOS system can shorten the time from receiving orders to send orders, shorten the delivery time for goods of orders, reduce to the loss rate of merchandise orders; helps to reduce the inventory level of enterprise, improves the efficiency of inventory management; For manufacturers and wholesalers, retailers, through the analysis of orders information of retailers, it can be accurately judged selling merchandise and unsalable merchandise, and helps adjust plans of commodity production and marketing.

4.2.3 Computer Aided Design (CAD) and Computer-Aided Process Planning (CAPP). Computer Aided Engineering (CAE) and computer-aided manufacturing (CAM)

CAD/CAPP/CAE/CAM technology used mainly to support new products design and manufacturing. With the development of PDM (product data management), to effectively establish the integration of information between CAD, CAPP, CAE, CAM, and realize correct and rapid exchange of data among firms of supply chain, to further

speed up product development cycle and lower costs.

4.2.4 Enterprise Resource Planning (ERP), manufacturing resource planning II (MRPII), Just in Time (JIT)

ERP/ MRPII/ JIT is mainly used in production control and inventory control. Of course, the scope of ERP is more broader, it reflects the ideas of supply chain management that expand its application toother types industries from traditional manufacturing industries. Application of ERP/ MRPII/ JIT techniques can eliminate a variety complex issues in manufacturing, promoting changes of business processes, information processes and the organizational structure, improve the flexibility of enterprise production and the entire supply chain. guarantee the normal operation of the production and supply chain.

4.2.5 Customer Relationship Management (CRM)

Customer Relationship Management (CRM) refers to constantly accumulated customer inf ormation in the process of a enterprise’s operation, and meet individual customer needs by the use of customer information to make marketing strategies. the most important function modules of CRM are customer services, marketing, sales. Through apply CRM to the sharing of information between enterprises, it can enhance services between the enterprises in the supply chain, improve customer satisfaction, maintain high customer retention, develop a positive impact to customer benefits and potential benefits.

4.2.6 E-commerce

E-commerce refers to complete business transaction between the various participants in electronic form, but not by physical exchange or direct physical contact, It includes electronic data interchange (EDI), electronic means of payment, electronic ordering systems, e-mail, fax, Internet, electronic bulletin systems, bar-coding, image processing, intelligent cards and so on. In supply chain management, E-commerce generally have two types: business-to-business (B2B) and business-to-consumer (B2C). E-commerce system improve the operational efficiency of the supply chain management of enterprises in supply management, inventory management, transportation management and information circulation.

供应链管理的信息技术支持系统

姜华,杨静,河北工程大学,经济与管理学院,中国邯郸

摘要:-有效的供应链管理是在信息传递和分享高品质的基础之上,这将依赖于信息技术提供可靠的大力支持。本文针对供应链信息流的特点,讨论了信息技术对供应链管理和支持系统的影响。

关键词:-供应链管理;信息技术支持系统;信息流;供应链;信息

一、引言

供应链管理(SCM)的兴起是缘于企业试图消除因信息传递太慢或错误而误导的生产及存货计划。90年代,一些计算机的制造商如HP,或生产家庭用品的宝洁(P & G)开始将信息系统作上下游整合,希望通过正确和快速的信息传递、分析和整合,达到对市场的需求作快速反映并降低库存等目的。因此,有效的供应链管理是建立在高质量的信息传递和共享的基础上,而这又离不开信息技术提供的可靠支持。

二、供应链信息流的特点

在当今时代,信息成为了决定企业生存与发展的关键因素,任何一个企业都要面对如何集成信息的问题。信息既有来自上下游企业的纵向信息,也有来自企业内部的横向信息,还有来自宏观层面上的信息。如何传递和共享这些信息,将上下游企业的经济行为以及企业内

部各部门、各岗位的职能行为协调起来,就是供应链管理所要处理的核心问题。与单个企业情况相比,供应链作为一种扩展企业,其信息流动和获取方式表现出自己的特色。

1.覆盖范围广

供应链中的信息流覆盖了从供应商、制造商到分销商再到零售商等供应链中的所有环节。其信息流分为需求信息流和供应信息流,这是两个不同流向的信息流。当需求信息(如客户定单、生产计划、采购合同等)从需方向供方流动时,便引发物流。同时供应信息(如入库单、完工报告单、库存记录、可供销售量、提货发运单等)又同物料一起沿着供应链从供方向需方流动。单个企业下的信息流则主要限定在企业内部的进销存记录(见图)。

图供应链的信息流与单个企业的信息流

2.获取途径多

由于供应链中的企业是一种协作关系和利益共同体,因而供应链中的信息获取渠道众多,对于需求信息来说既有来自顾客也有来自分销商和零售商的;供应信息则来自于各供应商,这些信息通过供应链信息系统而在所有的企业里流动与分享。对于单个企业情况来说,由于没有与上下游企业形成利益共同体,因此单个企业的信息获取则完全依赖于自己的收集。

3.信息质量高

由于存在专业分工,供应链中的信息质量要强于单个企业下的信息质量,例如,分销商和零售商可以专门负责收集需求信息,供应商则收集供应信息,生产厂商收集产品信息等。

三、信息技术和供应链管理

信息技术的发展为供应链管理提供了有效的支持。关于如何看待信息技术对供应链管理的影响,如何在供应链管理中利用信息技术等问题,通过研究,基本上可以归纳为三个方面:

1.加强供应链中的信息共享可以有效地改进供应链的管理

当供应链各成员只根据来自其相邻下级的信息进行决策时,系统将产生需求放大现象,引起这种现象的原因并不是各成员的非理性,而是在实际信息不清楚情况下的理性决策,包括在非平稳需求情况下的需求预测、在预期缺货情况下增

加定货量、在存在固定定货费用和批量效应时增大定货批量等。这种现象的发生将对供应链所有成员都产生负面影响。为了消除或抑制这种现象,可以在供应链范围内采取相应对策,如加强信息共享、缩短延迟时间、协调定货和简化促销行为等。

2.信息技术的发展加强了供应链内部的协作

信息技术的发展使得企业能够更方便地使用信息技术与供应链其他成员进行交流和协作,使用费用也因此相对降低,使企业能够在同样的信息使用费用水平上选择更多的供应商以获得更便宜的供应和服务。也就是说,企业与其供应商之间的关系将有可能变得不可靠、不稳定,但实际上成功的企业选择的供应商数目并没有增加,而是减少了。其实,“企业与其供应商和用户之间必须建立一种协作关系”这一点在JIT 中已经有明确的要求,只是没有受到足够的重视。3.信息技术的发展可以帮助建立更完善的用户需求模型

最终用户是供应链的一个重要组成部分,对用户需求的响应状况则是供应链管理的一个很重要的评价指标,因此能够较好地掌握用户需求是供应链管理的基础。目前很多文章都对需求及其分布采用了不同的近似假设,但实际上需求是随机的,其发布也不是如我们一般所

假设的那样理想。因此,有必要在考虑供应链的库存控制问题中考虑对需求的预测,根据不同的情况选择不同的预测模型,建立恰当的需求模型。

四、供应链管理的信息技术支撑体系

供应链信息系统的建立是需要大量信息技术来支撑的,我们从供应链管理涉及的主要领域来谈信息技术在供应链管理中形成的支撑体系。供应链管理涉及的主要领域有:产品(服务)设计、生产、市场营销、客户服务、物流供应等。它是以同步化、集成化生产计划为指导,通过采用各种不同信息技术来提高这些领域的运作绩效。信息技术对供应链的支撑可分为两个层面。

4.1.第一个层面是由标识代码技术、自动识别与数据采集技术、电子数据交换技术、互联网技术等基础信息技术构成

4.1.1标识代码技术

统一的信息编码是实现供应链中贸易伙伴间的数据交换与共享的基础。没有它,自动识别技术与电子数据交换(EDI)就不可能实现。

4.1.2自动识别与数据采集技术

自动识别和数据采集(AIDC)已成为供应链管理过程中处理物流信息的理想技术。借助自动识别技术,通过自动数据识别和数据采集,可保证供应链各环节高速准确的数据获取及实时控制。目前,供应链管理中,最常用的AIDC 技术是条码技术和射频识别技术。射频识别(RFID)技术是一种较新的自动识别技术。由于射频识别技术的特点是可以非接触识读、可识别高速运动物体、抗恶劣环境、保密性强、可同时识别多个识别对象等,因而广泛应用于制造业及其他不适宜条码标签存在的环境中。在供应链过程控制中,它被广泛应用于运输工具的自动识别(AVI)、物品的跟踪与监视、店铺防盗系统、高速公路收费及智能交通系统(ITS)、生产线的自动化及过程控制等方面。

4.1.3电子数据交换(EDI)

EDI技术是指不同的企业之间为了提高经营活动的效率在标准化的基础上通过计算机网络进行数据传输和交换的方法。EDI 是实施快速响应(QR)、高效消费者响应(ECR)、高效补货等方法必不可少的技术。目前,几乎所有的供应链管理的运作方法都离不开EDI 技术的支持。

4.1.4互联网技术

互联网技术的蓬勃发展为供应链成员信息共享和交流提供了相对方便、快捷和廉价的基础工具。随着无线上网技术的发展和成熟,供应链成员可以不受空间限制地从事商业活动。

4.2第二层面是在一些基础信息技术的基础上所开发的支持企业生产、经营管理各个方面的信息系统和应用软件

在具体集成和应用这些系统时,不应仅仅将它们视为是一种技术解决方案,而应深刻理解它们所折射的管理思想。

4.2.1销售时点信息系统(POS)

POS 是指通过自动读取设备(收银机)在销售商品时直接读取商品销售信息,并通过通讯网络和计算机系统传送至有关部门进行分析加工以提高经营效率的系统。

4.2.2电子自动订货系统(EOS)

EOS是指企业间利用通讯网络(VAN或Internet)和终端设备以在\线联结

(ON-LINE)方式进行订货作业和订货信息交换的系统。相对于传统的订货方式,EOS系统可以缩短从接到订单到发出订货的时间,缩短订货商品的交货期,减少商品订单的出错率;有利于减少企业的库存水平,提高企业的库存管理效率;对于生产厂家和批发商来说,通过分析零售商的商品订货信息,能准确判断畅销商品和滞销商品,有利于调整商品生产和销售计划。

4.2.3计算机辅助设计(CAD)、计算机辅助工艺规划(CAPP)、计算机辅助工程(CAE)和计算机辅助制造(CAM)

CAD/CAPP/CAE/CAM 等计算机辅助技术主要用于支持新产品设计与制造。随着PDM(产品数据管理)发展,有效地建立了CAD、CAPP、CAE、CAM 之间的信息集成,实现供应链上各企业之间正确而快速的数据交换,从而进一步加快产品开发时间,降低了费用。

4.2.4企业资源计划(ERP)、制造资源计划(MRPII)、准时生产制(JIT)

ERP/ MRPII/ JIT等主要是用于企业生产控制和库存控制。当然ERP 的范围更广,已体现出了供应链管理的思想,其应用领域从传统制造业拓展到其他类型的行业。ERP/ MRPII/ JIT等技术的应用就可以解决企业生产中出现的多种复杂问题,促进了企业业务流程、信息流程和组织结构的变革,提高企业生产和整个供应链的柔性,保证生产及供应链的正常运行。

4.2.5客户关系管理(CRM)

客户关系管理(CRM)是指在企业的运营过程中不断累积客户信息,并使用获得的客户信息来制定市场战略以满足客户个性化需求。CRM 最主要的功能模块是客户服务、市场营销、销售。通过将CRM 应用于企业之间的信息共享,可以提升供应链上各企业之间的服务水平,提高客户满意度、维持较高的客户保留,对客户收益和潜在收益产生积极的影响等。

4.2.6电子商务

电子商务是各参与方之间以电子方式而不是通过物理交换或直接物理接触

完成的任何形式的业务交易,它包括电子数据交换(EDI)、电子支付手段、电子订货系统、电子邮件、传真、网络、电子公告系统、条码、图像处理、智能卡等。

毕业论文外文文献翻译-数据库管理系统的介绍

数据库管理系统的介绍 Raghu Ramakrishnan1 数据库(database,有时拼作data base)又称为电子数据库,是专门组织起来的一组数据或信息,其目的是为了便于计算机快速查询及检索。数据库的结构是专门设计的,在各种数据处理操作命令的支持下,可以简化数据的存储,检索,修改和删除。数据库可以存储在磁盘,磁带,光盘或其他辅助存储设备上。 数据库由一个或一套文件组成,其中的信息可以分解为记录,每一记录又包含一个或多个字段(或称为域)。字段是数据存取的基本单位。数据库用于描述实体,其中的一个字段通常表示与实体的某一属性相关的信息。通过关键字以及各种分类(排序)命令,用户可以对多条记录的字段进行查询,重新整理,分组或选择,以实体对某一类数据的检索,也可以生成报表。 所有数据库(最简单的除外)中都有复杂的数据关系及其链接。处理与创建,访问以及维护数据库记录有关的复杂任务的系统软件包叫做数据库管理系统(DBMS)。DBMS软件包中的程序在数据库与其用户间建立接口。(这些用户可以是应用程序员,管理员及其他需要信息的人员和各种操作系统程序)。 DBMS可组织,处理和表示从数据库中选出的数据元。该功能使决策者能搜索,探查和查询数据库的内容,从而对在正规报告中没有的,不再出现的且无法预料的问题做出回答。这些问题最初可能是模糊的并且(或者)是定义不恰当的,但是人们可以浏览数据库直到获得所需的信息。简言之,DBMS将“管理”存储的数据项,并从公共数据库中汇集所需的数据项以回答非程序员的询问。 DBMS由3个主要部分组成:(1)存储子系统,用来存储和检索文件中的数据;(2)建模和操作子系统,提供组织数据以及添加,删除,维护,更新数据的方法;(3)用户和DBMS之间的接口。在提高数据库管理系统的价值和有效性方面正在展现以下一些重要发展趋势; 1.管理人员需要最新的信息以做出有效的决策。 2.客户需要越来越复杂的信息服务以及更多的有关其订单,发票和账号的当前信息。 3.用户发现他们可以使用传统的程序设计语言,在很短的一段时间内用数据1Database Management Systems( 3th Edition ),Wiley ,2004, 5-12

我国第三方物流中存在的问题、原因及战略选择 熊卫 【摘要】我国物流业发展刚刚起步,第三方物流的理论和实践等方面都比较薄弱。本文指出我国第三方物流存在的问题在于国内外第三方物流企业差距、物流效率不高、缺乏系统性管理、物流平台构筑滞后、物流管理观念落后等。分析了产生上述问题的原因,并提出了精益物流、中小型第三方物流企业价值链联盟、大型第三方物流企业虚拟化战略等三种可供选择的第三方物流企业发展战略。 【关键词】第三方物流;精益物流战略;价值链联盟;虚拟化战略 1引言 长期以来,我国国内企业对采购、运输、仓储、代理、包装、加工、配送等环节控制能力不强,在“采购黑洞”、“物流陷井”中造成的损失浪费难以计算。因此,对第三方物流的研究,对于促进我国经济整体效益的提高有着非常重要的理论和实践意义。本文试图对我国策三方物流存在的问题及原因进行分析探讨,并提出第三方物流几种可行的战略选择。 2我国第三方物流业存在的主要问题 (一)我国策三方物流企业与国外第三方物流企业的差距较大,具体表现在以下几个方面: 1、规模经济及资本差距明显。由于国外的大型第三方物流企业从全球经营的战略出发,其规模和资本优势是毫无疑问的,尤其初创时期的我国策三方物流业,本身的规模就很小,国外巨头雄厚的资本令国内企业相形见绌。 2、我国策三方物流业企业提供的物流服务水准及质量控制远不如国外同行。当国内一些企业还在把物流理解成“卡车加仓库“的时候,国外的物流企业早已完成了一系列标准化的改造。同时,国外的物流组织能力非常强大,例如德国一家第三方物流公司,公司各方面的物流专家遍布欧洲各地。如果有客户的货物需要经达不同的国家,那么欧洲各地的这些专家就在网上设计出一个最佳的物流解决方案。这种提供解决方案的能力就是这第三方物流公司的核心能力,而不像国内公司号称拥有多少条船,多少辆车。 3、我国加入WTO后物流产业的门槛降低。在物流服务业方面:我国承诺所有的服务行业,在经过合理过渡期后,取消大部分外国股权限制,不限制外国服务供应商进入

科技文章摘译 Definition of a Management Information System There is no consensus of the definition of the term "management information system". Some writers prefer alternative terminology such as "information processing system", "information and decision system", "organizational information system", or simply "information system" to refer to the computer-based information processing system which supports the operations, management, and decision-making functions of an organization. This text uses “MIS” because it is descriptive and generally understood; it also frequently uses “information system” instead of “MIS” to refer to an organizational information system. A definition of a management information system, as the term is generally understood, is an integrated, user-machine system for providing information to support operations, management, and decision-making functions in an organization. The system utilizes computer hardware and software; manual procedures; models for analysis planning, control and decision making; and a database. The fact that it is an integrated system does not mean that it is a single, monolithic structure; rather, it means that the parts fit into an overall design. The elements of the definition are highlighted below. 1 Computer-based user-machine system Conceptually, management information can exist without computer, but it is the power of the computer which makes MIS feasible. The question is not whether computers should be used in management information system, but the extent to which information use should be computerized. The concept of a user-machine system implies that some tasks are best performed by humans, while others are best done by machine. The user of an MIS is any person responsible for entering input data, instructing the system, or utilizing the information output of the system. For many problems, the user and the computer form a combined system with results obtained through a set of interactions between the computer and the user. User-machine interaction is facilitated by operation in which the user’s input-output device (usually a visual display terminal) is connected to the computer. The computer can be a personal computer serving only one user or a large computer that

Actually , friction is present to some degree whenever two parts are in contact and move on each other. The term friction refers to the resistance of two or more parts to movement. Friction is harmful or valuable depending upon where it occurs. friction is necessary for fastening devices such as screws and rivets which depend upon friction to hold the fastener and the parts together. Belt drivers, brakes, and tires are additional applications where friction is necessary. The friction of moving parts in a machine is harmful because it reduces the mechanical advantage of the device. The heat produced by friction is lost energy because no work takes place. Also , greater power is required to overcome the increased friction. Heat is destructive in that it causes expansion. Expansion may cause a bearing or sliding surface to fit tighter. If a great enough pressure builds up because made from low temperature materials may melt. There are three types of friction which must be overcome in moving parts: (1)starting, (2)sliding, and(3)rolling. Starting friction is the friction between two solids that tend to resist movement. When two parts are at a state of rest, the surface irregularities of both parts tend to interlock and form a wedging action.

外文文献原稿和译文 原稿 JSP JSP (JavaServer Pages) is initiated by Sun Microsystems, Inc., with many companies to participate in the establishment of a dynamic web page technical standards. JSP technology somewhat similar to ASP technology, it is in the traditional HTML web page document (*. htm, *. html) to insert the Java programming paragraph (Scriptlet) and JSP tag (tag), thus JSP documents (*. jsp). Using JSP development of the Web application is cross-platform that can run on Linux, is also available for other operating systems. JSP technology to use the Java programming language prepared by the category of XML tags and scriptlets, to produce dynamic pages package processing logic. Page also visit by tags and scriptlets exist in the services side of the resources of logic. JSP page logic and web page design and display separation, support reusable component-based design, Web-based application development is rapid and easy. Web server in the face of visits JSP page request, the first implementation of the procedures of, and then together with the results of the implementation of JSP documents in HTML code with the return to the customer. Insert the Java programming operation of the database can be re-oriented websites, in order to achieve the establishment of dynamic pages needed to function. JSP and Java Servlet, is in the implementation of the server, usually returned to the client is an HTML text, as long as the client browser will be able to visit. JSP pages from HTML code and Java code embedded in one of the components. The server was in the pages of client requests after the Java code and then will generate the HTML pages to return to the client browser. Java Servlet JSP is the technical foundation and large-scale Web application development needs of Java Servlet and JSP support to

文献翻译 原文 Combining JSP and Servlets The technology of JSP and Servlet is the most important technology which use Java technology to exploit request of server, and it is also the standard which exploit business application .Java developers prefer to use it for a variety of reasons, one of which is already familiar with the Java language for the development of this technology are easy to learn Java to the other is "a preparation, run everywhere" to bring the concept of Web applications, To achieve a "one-prepared everywhere realized." And more importantly, if followed some of the principles of good design, it can be said of separating and content to create high-quality, reusable, easy to maintain and modify the application. For example, if the document in HTML embedded Java code too much (script), will lead the developed application is extremely complex, difficult to read, it is not easy reuse, but also for future maintenance and modification will also cause difficulties. In fact, CSDN the JSP / Servlet forum, can often see some questions, the code is very long, can logic is not very clear, a large number of HTML and Java code mixed together. This is the random development of the defects. Early dynamic pages mainly CGI (Common Gateway Interface, public Gateway Interface) technology, you can use different languages of the CGI programs, such as VB, C / C + + or Delphi, and so on. Though the technology of CGI is developed and powerful, because of difficulties in programming, and low efficiency, modify complex shortcomings, it is gradually being replaced by the trend. Of all the new technology, JSP / Servlet with more efficient and easy to program, more powerful, more secure and has a good portability, they have been many people believe that the future is the most dynamic site of the future development of technology. Similar to CGI, Servlet support request / response model. When a customer submit a request to the server, the server presented the request Servlet, Servlet responsible for handling requests and generate a response, and then gave the server, and then from the server sent to

The paper goes on to review the literature on BPR. It explores the principles and assumptions behind reengineering, looks for commonfactors behind its successes or failures, examines case studies, and presents alternatives to "classical" reengineering theory. The paper pays particular attention to the role of information technology in BPR. In conclusion, the paper offers somespecific recommendations regarding reengineering. Old Wine in New Bottles The concept of reengineering traces its origins back to management theories developed as early as the nineteenth century. The purpose of reengineering is to "make all your processes the best-in-class." Frederick Taylor suggested in the 1880's that managers use process reengineering methods to discover the best processes for performing work, and that these processes be reengineered to optimize productivity. BPR echoes the classical belief that there is one best way to conduct tasks. In Taylor's time, technology did not allow large companies to design processes in across-functional or cross-departmental manner. Specialization was the state-of-theart method to improve efficiency given the technology of the time.

信息系统和数据库中英文对照外文翻译文献

中英文对照翻译 信息系统开发和数据库开发 在许多组织中,数据库开发是从企业数据建模开始的,企业数据建模确定了组织数据库的范围和一般内容。这一步骤通常发生在一个组织进行信息系统规划的过程中,它的目的是为组织数据创建一个整体的描述或解释,而不是设计一个特定的数据库。一个特定的数据库为一个或多个信息系统提供数据,而企业数据模型(可能包含许多数据库)描述了由组织维护的数据的范围。在企业数据建模时,你审查当前的系统,分析需要支持的业务领域的本质,描述需要进一步抽象的数据,并且规划一个或多个数据库开发项目。图1显示松谷家具公司的企业数据模型的一个部分。 1.1 信息系统体系结构 如图1所示,高级的数据模型仅仅是总体信息系统体系结构(ISA)一个部分或一个组织信息系统的蓝图。在信息系统规划期间,你可以建立一个企业数据模型作为整个信息系统体系结构的一部分。根据Zachman(1987)、Sowa和Zachman (1992)的观点,一个信息系统体系结构由以下6个关键部分组成: 数据(如图1所示,但是也有其他的表示方法)。 操纵数据的处理(着系可以用数据流图、带方法的对象模型或者其他符号表示)。 网络,它在组织内并在组织与它的主要业务伙伴之间传输数据(它可以通过网络连接和拓扑图来显示)。 人,人执行处理并且是数据和信息的来源和接收者(人在过程模型中显示为数据的发送者和接收者)。 执行过程的事件和时间点(它们可以用状态转换图和其他的方式来显示)。 事件的原因和数据处理的规则(经常以文本形式显示,但是也存在一些用于规划的图表工具,如决策表)。 1.2 信息工程 信息系统的规划者按照信息系统规划的特定方法开发出信息系统的体系结构。信息工程是一种正式的和流行的方法。信息工程是一种面向数据的创建和维护信息系统的方法。因为信息工程是面向数据的,所以当你开始理解数据库是怎样被标识和定义时,信息工程的一种简洁的解释是非常有帮助的。信息工程遵循自顶向下规划的方法,其中,特定的信息系统从对信息需求的广泛理解中推导出来(例如,我们需要关于顾客、产品、供应商、销售员和加工中心的数据),而不是合并许多详尽的信息请求(如一个订单输入屏幕或按照地域报告的销售汇总)。自顶向下规划可使开发人员更全面地规划信息系统,提供一种考虑系统组件集成的方法,增进对信息系统与业务目标的关系的理解,加深对信息系统在整个组织中的影响的理解。 信息工程包括四个步骤:规划、分析、设计和实现。信息工程的规划阶段产

证券承销业务的商业银行:激励冲突,范围经济和工程质量 乔治.卡纳塔斯我们研究这个问题的证券承销业务,分析检验这些激励冲突,出借所面临的中介机构和证券承销,从而将成本加强给他们的客户寻求融资。尽管这个成本,如果有足够大的范围和承销经济体联合贷款,公司可以使用此类中间层。我们证实监管分离这样的组合中介可能是最好的,如果公司认识到中介的后续激励,冲突在选择资助的项目和如果有一个社会银行融资成本低质量的项目。我们还检查条件作中间的信誉建立以减轻冲突的动机不需要监管。 争论涉及监管分离借贷和承销加剧了最近的商业银行寻求新的机遇来取代他们的传统业务,正面临日益激烈的竞争。一个参数分离与银行的动机,否则就必须为其质量差,证券承销的借款人,然后将所得承还这些贷款。这种利益冲突的出现被认为从有关的金融中介机构的作用进行了详细描写,例如在钻石(1984)和室里罗摩克里希啦和塔克尔(1984)。银行在租借期间挖掘信息表明质量差的借款人有动机后来作为承销商歪曲这个质量资本市场,从而帮助发行证券的有效的,在某种程度上承还银行贷款。而商业银行被视为特殊借款人发掘信息的过程中,他们的监测的借款人在租借期间,投资银行被认为评估公司为他们打算承销证券,并为他们提供一个质量认证。 承销商没有股权在进行客户公司不想隐瞒信息获得的准备过程中,证券市场。并不是所有的同意这种激励的重要性冲突是提供一个理由监管分离借贷和承销。一些,例如贝斯顿(1990)都认为,这样一个不存在利益冲突的历史。别人的位置,即使他确实存在,银行的关心其声誉将减轻这种潜在的问题,它的重要性已经大大夸大了。尽管观点都在支持和反对格拉斯斯蒂格尔已经频繁的表达,还没有足够的证据对其需要,比如说,克罗兹纳,雷简(1994),普里(1994)。我们的目的不是评价的重要意义,中介的潜在利益冲突结合贷款和承销。相反,我们将假定存在这样激励冲突并检查它如何与潜在的利益相结合的两种形式的中介以及激励它提供企业家在选择项目需要融资的质量。因此我们将鉴别特定的因素进行分析,为我们特定的因素进行分析,为我们利益冲突的相关政策的考虑以及元素必须是微不足道的,在这方面我们还将检查往往根据参数,银行的声誉将减轻这种担忧的激励问题。 我们分析的核心信息范围的经济体。在某种程度上相同的中介公司和承销商给一个其证券有储蓄在信息生产。另一方面,公司使用银行,也持有他们的承销商债务可能承
