Designing And Implementation Of The Logistic Management System Based On UML And J2EE

Establishing the advanced management information system intransportation enterprise in west China is a subproblem of the applicationresearch on transportation technique in west China. The logistics enterprise inwest China are numerous but lacking of the integrated pattern on themanagement. Therefore, it is feasible to develop the management informationsystem on the basis of a well managed enterprise and popularize to otherenterprises in west China. Lanzhou Sanhetong Corporation which this subjectinvolved has already been some third party's logistics pattern. Thebackground of the third party's logistics is that square the owner of enterprisescargo are centralized to the key business, have advanced the trend withrationalized logistics. Compared with in the transportation investment withoutthe facilities, most enterprises incline to invest the fund in the staple in orderto obtain more interests. As a circle of giving a new lease of life to enterprisesat the same time, some enterprises totally entrust the logistics department tooutside enterprises. Third party logistics enterprise utilize the trend, accept alot of logistics business of enterprise to carry on. Third party's logistics andthe traditional logistics have the difference in that the traditional logisticsmode is to face single supplier or purchaser, and third party's logistics will befaced to both supplier and purchaser. This thesis first order and analysethe collected data to found out about the overview of the logistics industry ,then summarize and design a rational method of logistics informationsystem according to the characteristic of the logistics industry.Computer software is now widely used in all kinds of industries.However, under existing technology, the realization of most software iscomplicated. When the problems required to be solved with the softwarebecome more and more complicated, software development becomes morecomplicated accordingly. In this case, modeling is very important for thesuccess of the software project. In all the methods of software modeling,object-oriented analysis and design is the major one. And UML, as thestandard modeling language in the object-oriented field, has been used widelyin software modeling. This thesis does a research on object-oriented softwaremodeling with UML by analyzing and discussing the development of thelogistic management information system.J2EE is the technology used to realize the system. It is a series of normsand criteria provided by SUN to construct the enterprise application usingJava technology. J2EE is also a standard in object-oriented field. CombiningUML and J2EE, thus the whole system is built on the uniform standards. Andin designing phase, the thesis adopts MVC (Model-View-Controller) tooptimize the architecture of the system. Architecture of MVC is used to divideapplication program into three levels to make the structure of the systemclearer. Because separate the code of different functions, realize thesegregation of the module and benefit the maintenance in the future. In thedevelopment of the project, such segregation helps three parts to run side byside, accelerate the project progress. In the stage of system designing andrealization, it described how to set up system model and transform with UMLinto real system of J2EE technology.This paper proposed a global framework and requirements of the systemof Sanhetong logistics management system. The main work of this paper is asfollows: Firstly, according to the enterprise edition system architectureprovided by the J2EE criterion, we analyzed and designed the logistics systemthrough usecase modeling, action modeling and structure modeling. Secondly,based on the function requirement of the major line business in the enterprise,we presented the use case diagram, sequence diagram and class diagram.Thirdly, taking the model we proposed above as the basis, we constructed thegeneral code framework by using the JBuilder visual design tool, andprogrammed the whole specification code based on it. The logistics system weproposed can primarily solve the requirements of the two major line businessincluding the main business and local distribution. The system implementedeight major submodules: order management, major line transportationmanagement, local distributing business management, vehicle transportationdispatching management, finance management, business adjustment, storagemanagement and system management. The implemented system has aneffective management of all kinds of resources in Sanhetong Corporation, andgreatly simplified the process of some operation, curtailed the processing time,thus make it more convenient for the customers to query their transportationgoods. Furthermore, most of the statistic report will be created automaticallyin the last stage on finance accounting, thus improve the efficiency andaccurateness of statistic, and was accepted by all the departments of thecompany.
