development are also increasing -is puts forward newrequirements for organizational development requiringorganizations to meet their needs At the same time en-terprises need to continuously improve improve com-petitiveness improve logistics management methods andimprove logistics management levels [1]

By studying the current status existing problems andactual needs of the current logistics management system wedesign a management information system for logisticsmanagement It helps to accelerate the automation of lo-gistics management and the rapid development of computerapplications leads to the development of business man-agement Increasing social competition and widespread useof information force companies to adapt to social trends andrequire management automation to improve the competi-tiveness of industry organizations With the development ofChinarsquos logistics industry and the development of traditionalself-recording methods that the company cannot cover thisis also conducive to improving the efficiency of logisticsmanagement business processing -e companyrsquos businessneeds are increasing and customers want speed and themost accurate service It has also become a standard forcustomers to evaluate companies so how to improvebusiness processing efficiency and management has becomea key issue hindering the development of manufacturingcompanies -e system can help organizations build acomprehensive logistics system which plays an importantrole in improving employee productivity and managinglogistics automation

Jagoda and Samaranayake put forward the conceptualframework of ERP system implementation by combining thestate gate method with the preimplementation roadmap It isfound that an alternative integrated method based on thephase gate method is proposed to implement the enterpriseresource planning (ERP) system which will enhance theeffectiveness of the ERP project [2] However it is far fromenough to build a conceptual framework -e theory andpractice should also be combined At present choosing theright enterprise resource planning (ERP) system is the mainchallenge facing business managers Jafarnejad A proposes acombined multicriteria decision (MCDM) method [3]which will determine the most important use of Shannonentropy technology for ERP selection standard-rough thismethod the previous research results can be integrated andthe judgment of industry experts or organizational managerscan also be integrated to select the appropriate ERP system[4] However this method only discusses the choice of ERPsystem and does not have an in-depth understanding of howthe ERP system is applied Many researchers have studiedvarious key success factors and different reasons for thefailure of ERP implementation projects Although there aredetailed literature forecasts the purpose of this research byAleksander is to develop and evaluate the main humanfactor (PHF) model and confirm the significant impact ofPHF on the success of traditional CSF and projects [5]However the development of the main human criticalsuccess factor model for the implementation of the ERPsystem is by no means simple and the feasibility of the studyis not high

-e innovation of this article is as follows (1) Due to thedrawbacks of the traditional logistics information systemand ERP system the logistics function of the ERP system hasbeen strengthened so that the logistics information man-agement system based on ERP not only has strong logisticsprocessing capabilities but also maintains the ERP systemOther information processing capabilities are as follows (2)-e development and implementation of an ERP-basedlogistics information management system not only reducesthe operating costs of the logistics business system but alsoreduces logistics costs

2 Research Method of ERP System in SupplyChain Enterprise Logistics InformationManagement System

21 ERP System Enterprise resource planning is a combi-nation of modern advanced information technology andsystematic management concepts based on supply chain-oriented management ideas (integrating relevant parts andtheir various links into its operations) [6ndash8] By closelyintegrating business and construction processes with thesupply and demand system plan design and control thecompanyrsquos logistics capital flow work flow and value-added flow etc and rationally arrange the organizationrsquosproduction supply and marketing activities so that theorganization can use all resources in a timely manner It is anintegrated information management system and manage-ment platform that supports the organizationrsquos decision-making production and operation [9]

211 e Definition and Development of ERP In the early1990s Gartner Group Inc a well-known American com-puter technology consulting and evaluation team based onthe development of computer data processing technologyand the needs of enterprise supply chain management at thetime predicted this trend [10 11] In the information agethe development of production management informationsystems and the upcoming changes make it possible for theconcept of ERP and the planning of business resources

ERP is a complete system that can collect all internalresources of the organization and execute effective planningand control to achieve maximum benefits [12] Its goal is toimprove information logistics capital flow value flow andbusiness flow by using programming and control as abenchmark and using network and information technologyas a platform to integrate marketing sales and customersand improve customer satisfaction [13] Functions such asmarket planning production financing quality servicedata integration and business process reengineering (BPR)are combined to solve the concepts and methods of supplychain management (SCM) [14]

It can be divided into three levels management ideassoftware products and management systems [12]

(1) -e standard business management system proposedby Garter Group Inc is developed based on MRPII(Manufacturing Resource Planning) -is is a managementconcept that supports the supply chain (2) With integrating

clientserver systems relational database structure object-oriented technology graphical user interface fourth-gen-eration language (4GL) network communication softwareproducts another success in the information industry isbased on the idea of ERPmanagement [2 15] (3) A businessresource management system combines corporate man-agement concepts business processes basic informationhuman resources and materials computer hardware andsoftware -e internal and external resources of the enter-prise organization are managed and optimally configuredthrough the network -e conceptual hierarchy of a newgeneration of management information system [16] ERPthat manages information at the enterprise level can beshown in Figure 1

-e development of ERP has gone through four maindevelopment stages [5 17]

-e first step MRP (Material Requirements Design)was created in the 1960s and is mainly used for pro-curement management and inventory control Its mainfunction is to use BOM inventory information andmain production plan to calculate materialrequirements-e second stage Closed-loop MRP was created basedon MRP in the 1970s It combines original capacityplanning capacity demand planning production andprocurement creating feedback and creating a closedloop-e third stage MRPII-e fourth stage ERP (Enterprise Resource Planning)was born in the early 1990s On the basis of MRPIIfunctions such as distribution management humanresource management logistics management qualitymanagement and decision support systems wereadded Everything is an extension from supplier tocustomer ERP uses advanced information technologysuch as network technology Internet graphical in-terface fourth-generation computer language rela-tional database distributed database processing andopen clientserver system As a result the integrationcapabilities are enhanced and the organizationrsquos globaloperations can be supported

212 Superiority of ERP System ERP system will bringdirect and indirect benefits to enterprises the following areits advantages [18 19]

(1) Business integration At this time it is the mostadvantageous point of all the advantages because theERP system can realize the promotion of groupbusiness

(2) It is highly adaptable -is is the second importantadvantage of the ERP system -e ERP system canhandle different currencies and accounting stan-dards as a whole and at the same time carry out theexecution of different functions and assign them todifferent departments for implementation -isadaptability is the basic prerequisite for adapting to

the general trend of the organization and main-taining the unity of the system

(3) Better analysis and planning capabilities ERP sys-tems can make full use of various decision supportsystems and decision simulation functions to com-prehensively use relevant business data in real timeso that decision makers have strong support canensure the correctness of decisions and make de-cisions-e correct strategy leads the development ofthe enterprise

(4) Ability to apply the latest and most advancedtechnology In order to benefit from the new de-velopment of technology ERP suppliers mustquickly adjust their ERP systems because ERPsystems can adapt to todayrsquos fast-developing tech-nology and gain in the information age Operationenables companies to better adapt to the ever-changing business environment

22 BS Architecture and CS Architecture My countryrsquossoftware development industry has gone from the initialworkshop slash-and-burn development to the currentiterative development method of prototypes using ad-vanced UML development concepts During this periodmany detours have been taken and many advancedconcepts have been introduced from abroad [20] Aftergetting rid of the initial low-efficiency standalone oper-ation mode software development has gradually devel-oped toward network interconnection From local areanetworks to metropolitan area networks to the Internetthe impact of software on our lives and the promotion ofproductivity have become more and more significantAmong them the more representative software developedwith CS architecture model are QQ Fox-mail antivirussoftware input method mobile phone APP etc while theapplication system built using BS architecture includese-mail system personnel management system CMSsystem etc [21 22]

221 e Difference between BS and CS Architecture(1) Difference in hardware environment

-e CS architecture uses special software to beplaced on the client side and the server side -e

operation of the special software takes up a lot ofserver resources and requires more server hardware[23] Its professional application software requiresno small server data occupancy space servermemory resources and controller clock resources-e BS architecture uses the browser-side softwareand Web-logic middleware software that mostpeople have and uses the HTTP network inter-working protocol which has less restrictions onhardware and is suitable for large-scale crowd use[24]

(2) Difference in safety requirements-e CS architecture is mainly used in small-scaleenterprises and institutions with high security re-quirements It has relatively high security require-ments for data transmission security terminal accessserver authentication and user-side filling-in in-formation security -e BS architecture is mainlyoriented to a wider range of user groups Althoughencrypted transmission can be carried out throughHTTPS protocol and other methods it has lowerrequirements for security and higher requirementsfor user experience and ease of use [25]

(3) Difference in system operation and maintenance-e CS architecture is more complicated for thesystem operation and maintenance level Since itsarchitecture is inseparable as a whole it is necessaryto update the other end correspondingly to achievethe interconnection of data transmission on bothsides when upgrading and updating on the serverside or the client side -e system operation andmaintenance work of this information system ar-chitecture is relatively complicated and the systemoperation and maintenance cost will be relativelyhigher -e coupling of the BS architecture is veryloose -e server end is upgraded and the client enddoes not need to be upgraded -e B end of the BSarchitecture can use the userrsquos browser to competeand the B end of the BS architecture can be inmultiple -e system uses a browser to access theoperation and maintenance cost of this architectureis not high and the operation and maintenance willbe enhanced day by day [26]

(4) Differences in interface modes-e access mode of the CS architecture is based onthe Internet protocol suite and some special ap-plication business requirements are built on thenetwork layer or data link layer -e applicationsystem server will select the most suitable develop-ment language protocol according to a variety ofsituations and the meaning of each byte of data isclearly regulated -e interface protocol of the BSarchitecture basically uses the HTTP protocol andthe interface method uses the Web-Service interface-e specifications of its data packets have beenclearly stipulated by the international ISO

organization and the relevant protocols need to beidentified during the research and developmentprocess

(5) Differences in database connection methods-e client side of the CS architecture requires rel-atively short data flow display and storage time -ecommunication between the client side and theserver side is very frequent so the CS architectureserver and the client are always connected As long asthere is a data request demand it can be respondedto immediately although this will consume a lot ofdatabase resources but because the architecturegenerally has a relatively small number of terminalsand high real-time performance of the businessmost of them adopt this method For example atypical case of CS architecture often linking is thebanking system business

222 Advantages of BS and CS ArchitectureAdvantages of BS architecture (1) Wide range of applica-tions OS systems with browsers such as Chrome and Firefoxcan access the server-side application part according toestablished specifications and the server-side application partcan also provide on-demand services anytime anywhere (2)Low operation and maintenance costs -e architectureserver-side maintenance or function update client does notneed to cooperate so that what you see is what you get issynchronized (3) Low RampD cost and high efficiency -eTCPIP protocol suite of the Internet contains many sub-protocols and the use of these protocols is the basic of BSarchitecture communication [27]

Advantages of CS architecture (1) -ere is fast re-sponse speed (2) Strong transaction processing capabil-ities Application system development with targeted anddedicated personnel is the main advantage of the CS ar-chitecture which can be customized very personally forusers (3) -e interface is highly friendly and can meet theunique needs of users -e client software is developedcompletely according to user needs (4) High security Forclient-side management and control the client side can beaccompanied by a security scanning function and a ded-icated transmission protocol is used in the transmissionprocess -e transmission protocol can use either an in-ternationally accepted encryption protocol or an encryp-tion method set by yourself to ensure the security of thetransmitted data Since the server side of the CS archi-tecture is developed by enterprises and institutions in-formation leakage caused by backdoors of foreign servicesoftware can be basically eliminated (5) High data scal-ability Most of the CS architecture systems use largedatabases such as Oracle and DB2 -is kind of databasehas strong data scalability in terms of subdatabase queryand analysis of massive data (6) Massive computing powerMost of the work that consumes server-side system re-sources such as data calculation and information pro-cessing can be placed on the client side [28]


23 Multiple Linear Regression

231 General Form Multiple regression analysis is one ofthe methods to quantitatively predict the development andchange of things based on social economic phenomenaQuantitatively analyze the reasons for growth and themotivation of things obtain the quantitative relationshipbetween the variables of things and then predict theirgrowth and motivation [29] Suppose that the predictedobject is w and the factor that affects the predicted object isxi where i 1 2 3 is the number of influencing factorsxi are independent of each other and you should not choosetoo many factors that affect w otherwise there will beproblems such as multilinearity and heteroscedasticitywhich will affect the accuracy of the prediction results Inorder to avoid the collinearity problem in the predictionprocess in advance the correlation coefficient L can be usedto detect the correlation of the independence

Llt 03 considers that there is no correlation between thepredictors that is the predictors are independent of eachother

After the correct selection of influencing factors weassume that there is a linear correlation between the pre-dictor and the predicted object that isw f(x1 x2 x3 xk) is a linear function and themultiple regression model is established as

wi β0 + β1xi1 + β2xi2 + middot middot middot + βkxik + εi (2)

Among them β1 β2 βk is called regression coeffi-cient β0 is a constant term both can be called regressionparameters and εi is residual error -e regression coeffi-cient reflects the degree of influence on the predicted objectwhen the predictive factor x1 x2 x3 xk changes

3 The Research Experiment of ERP System inthe Logistics Information ManagementSystem of Supply Chain Enterprises

31 System Architecture of System Implementation -esystem mainly solves the following problems the process ofinformation transmission is not smooth the efficiency of thedelivery process is too low the ability to integrate resourcesis weak and the efficiency and service level cannot meet thegeneral standards required by the enterprise

In view of the development requirements of logisticsinformatization and the development trend in the trans-portation management process advanced logistics infor-mation technology must integrate advanced logisticsmanagement concepts and the combination of practice andtheory promotes the smooth completion of research anddevelopment Aiming at the system architecture the logisticscompany transportation management system is a platformwith great advantages It is oriented to multiparty logisticstransportation and belongs to the multidimensional logisticstransportation business at the management business level-e system needs to face different enterprise customers inspecific operations and meet the different needs of cus-tomers which requires the system to achieve complexfunctions in business -erefore the logistics and trans-portation information management system must realize themultidimensional architecture of the system so the system isdivided into a multilayer structure and each level has aninteractive relationship -e development and design of thissystemmainly adopt the BS structure-e specific structureis shown in Figure 2

System layer It provides software support for usersrsquonormal operating system including the system platforminstalled by the user the database system installed by theuser and the corresponding software which are the basics ofthe system Service layer It is the part that is built on theapplication basic platform and provides services for thesystem -e application basic platform integrates the de-velopment of the logistics transportation system the inte-gration of various applications and the foundation ofe-commerce -e platform provides corresponding servicesfor the system helping the system to exchange data at thebottom relying on the system layer to share data exchangedata with different applications and provide system logservices catalog management development frameworksuser permissions etc It provides an excuse for daily workand general applications and it is a portal for externalsystems to access the system -e service layer also provides

the encapsulation of some general classes as well as theservice classes commonly used in the system providingtransaction control data query security control systemmanagement and other aspects of interacting data with thebottom layer of the data -e business logic layer is mainlyfor handling various logistics-related business processes-ebusiness logic layer performs data operations by calling eachpackage class of the service layer -e presentation layer isthe layer where the user touches the system and displays thecorresponding system functions most intuitively to the user

32 Physical Architecture of the System According to thedescription of the architecture the realization of the physicalarchitecture of the system is divided into three layers basedon the BS structure which are the view layer the businesslayer and the data layer in turn

-eworkflow of the logistics system is as follows First theuser may have multiple browsers When the userrsquos browsersends a request to the middleware the system judges whetherthe user has the authority to perform the correspondingoperation according to the current userrsquos login informationsession If it meets the requirements the web applicationserver will process the browser-side request find the corre-sponding processing method start the data layer serviceprocess the data and return the processed data and results tothe web server container and the web server container returnsto the web server container Request support for concurrentoperations From the above operations the network topologyof the logistics system is shown in Figure 3

ERP-based enterprise logistics systems have certaincharacteristics such as consistency and convenience ofprojects unification and sharing decision-making flexibilityunification of advanced simulation and forecasting capitalflow and information flow etc -ese functions indicatebusiness logistics based on ERP -e information system is acomplete pillar logistics management system Realize theoverall benefits of production and logistics services in effectivemanagement and enhance the companyrsquos overall competi-tiveness Several experienced consultants talked about theirexperience in implementing IT logistics systems for ERP-based companies and said that to successfully implement anERP system three points depend on technology seven pointson talents and twelve points on data Although this statementis a bit exaggerated computers can only function if the in-formation is correct complete and timely otherwise they willproduce wrong results In other words the product databaseis the basis for the operation of enterprise logistics IT systemswith ERP capabilities -e application scope and depth of theERP-based business logistics system depend on the com-panyrsquos needs coverage and information content-erefore itis very important to prepare andmaintain a product database

33 System Detailed Design

331 Code Design -ere are the following principles incode design (1) -e design code must be optimized to meetthe needs of users When designing the code pay attentionto whether the loop condition is an infinite loop When


updating the database you must close the connection andclose the read and write stream when reading and writingfiles (2) A class represents a method trying to put somecommon methods and common constants into the commonclass (3) When designing the code write enough commentsso that the maintenance personnel can directly understandthe specific meaning of the written code and quickly locatethe code that needs to be modified (4) -e writing of thecode must conform to standardization If it is a constant itmust be static If the parameter passed by the method it is astatic parameter

332 Database Design Database design refers to the pro-cess of establishing a database that meets business needsafter the system implementer has selected specific databasesoftware When designing a database three stages are re-quired conceptual design logical design and physicaldesign

(1) Database conceptual structure design

-e database conceptual structure design is a con-ceptual model designed according to the needs of theenterprise It is an abstract expression of a concrete

development are also increasing -is puts forward newrequirements for organizational development requiringorganizations to meet their needs At the same time en-terprises need to continuously improve improve com-petitiveness improve logistics management methods andimprove logistics management levels [1]

By studying the current status existing problems andactual needs of the current logistics management system wedesign a management information system for logisticsmanagement It helps to accelerate the automation of lo-gistics management and the rapid development of computerapplications leads to the development of business man-agement Increasing social competition and widespread useof information force companies to adapt to social trends andrequire management automation to improve the competi-tiveness of industry organizations With the development ofChinarsquos logistics industry and the development of traditionalself-recording methods that the company cannot cover thisis also conducive to improving the efficiency of logisticsmanagement business processing -e companyrsquos businessneeds are increasing and customers want speed and themost accurate service It has also become a standard forcustomers to evaluate companies so how to improvebusiness processing efficiency and management has becomea key issue hindering the development of manufacturingcompanies -e system can help organizations build acomprehensive logistics system which plays an importantrole in improving employee productivity and managinglogistics automation

Jagoda and Samaranayake put forward the conceptualframework of ERP system implementation by combining thestate gate method with the preimplementation roadmap It isfound that an alternative integrated method based on thephase gate method is proposed to implement the enterpriseresource planning (ERP) system which will enhance theeffectiveness of the ERP project [2] However it is far fromenough to build a conceptual framework -e theory andpractice should also be combined At present choosing theright enterprise resource planning (ERP) system is the mainchallenge facing business managers Jafarnejad A proposes acombined multicriteria decision (MCDM) method [3]which will determine the most important use of Shannonentropy technology for ERP selection standard-rough thismethod the previous research results can be integrated andthe judgment of industry experts or organizational managerscan also be integrated to select the appropriate ERP system[4] However this method only discusses the choice of ERPsystem and does not have an in-depth understanding of howthe ERP system is applied Many researchers have studiedvarious key success factors and different reasons for thefailure of ERP implementation projects Although there aredetailed literature forecasts the purpose of this research byAleksander is to develop and evaluate the main humanfactor (PHF) model and confirm the significant impact ofPHF on the success of traditional CSF and projects [5]However the development of the main human criticalsuccess factor model for the implementation of the ERPsystem is by no means simple and the feasibility of the studyis not high

-e innovation of this article is as follows (1) Due to thedrawbacks of the traditional logistics information systemand ERP system the logistics function of the ERP system hasbeen strengthened so that the logistics information man-agement system based on ERP not only has strong logisticsprocessing capabilities but also maintains the ERP systemOther information processing capabilities are as follows (2)-e development and implementation of an ERP-basedlogistics information management system not only reducesthe operating costs of the logistics business system but alsoreduces logistics costs

2 Research Method of ERP System in SupplyChain Enterprise Logistics InformationManagement System

21 ERP System Enterprise resource planning is a combi-nation of modern advanced information technology andsystematic management concepts based on supply chain-oriented management ideas (integrating relevant parts andtheir various links into its operations) [6ndash8] By closelyintegrating business and construction processes with thesupply and demand system plan design and control thecompanyrsquos logistics capital flow work flow and value-added flow etc and rationally arrange the organizationrsquosproduction supply and marketing activities so that theorganization can use all resources in a timely manner It is anintegrated information management system and manage-ment platform that supports the organizationrsquos decision-making production and operation [9]

211 e Definition and Development of ERP In the early1990s Gartner Group Inc a well-known American com-puter technology consulting and evaluation team based onthe development of computer data processing technologyand the needs of enterprise supply chain management at thetime predicted this trend [10 11] In the information agethe development of production management informationsystems and the upcoming changes make it possible for theconcept of ERP and the planning of business resources

ERP is a complete system that can collect all internalresources of the organization and execute effective planningand control to achieve maximum benefits [12] Its goal is toimprove information logistics capital flow value flow andbusiness flow by using programming and control as abenchmark and using network and information technologyas a platform to integrate marketing sales and customersand improve customer satisfaction [13] Functions such asmarket planning production financing quality servicedata integration and business process reengineering (BPR)are combined to solve the concepts and methods of supplychain management (SCM) [14]

It can be divided into three levels management ideassoftware products and management systems [12]

(1) -e standard business management system proposedby Garter Group Inc is developed based on MRPII(Manufacturing Resource Planning) -is is a managementconcept that supports the supply chain (2) With integrating
