| In recent years, the sea transportation became in gradually the international trade the most main transport mode. While more and more ship transport companies have shipping container information management, also has launched own cargo insurance service, and forms the freight transportation safe coordinated process service gradually. Some kind on-line information service system also appear with it production, but the overwhelming majority system is too simple, besides cannot to have the data to make the intelligent analysis well, in the reusability, the maintenance, the stable aspect's performance is also unsatisfactory.This article proposed based on J2EE is the frame marine transportation management system management system's development. Based on the basic function,also used the data mining technology to analyze the massive customer information , this system had already carried on the development take the Japanese Mitsubishi Sumitomo marine cargo system as the example. Main research content is as follows:This system is based on the J2EE construction, has used three stratification modellings type, and has applied based on module's design concept and the MVC design pattern technology, has strongly entrusts with heavy responsibility the nature, the extendibility, the probability. Divides according to the MVC pattern this system the user view level, the controller level and the service model level, uses JSP, Servlet, EJB to carry on separately realizes.This system has carried on the functional design ,the module design, the development pattern layout, the database design according to the operation flow and the demand. This system is mainly composed of six modules, respectively is the user administration module, the dock administration module, the cargo insurance module, the report form and the inquiry module, the data analysis module, other administration module. The WEB page altogether has more than 130, the source code nearly 20000 lines, the author primary cognizance develops the dock administration module, the cargo insurance module and the data analysis module, WEB page 83, about the code 11000 lines.In the dock administration module, according to the analysis standard container berth movement pattern and the hardware composition, caused the container from to enter the floodgate to arrive at floodgate's entire revolution flow to be under the effective management. Has used the flow chart and the ER chart in this module manages as well as the operator schema alternately for between the dock each role information has carried on the analysis and the development. This module also provided the dump site plane demonstration function to help the management to grasp the dock well the current condition. In cargo insurance module, besides construction information system's hardware composition model, but also constructed for the customer to be able to register satisfies the personalized demand chit the system model, provided has been possible to act according to the customer for the policy-maker the first rank regular acknowledgment chit function. Moreover considered from the chit data's security that used the automatic filtration technology in this module to limit the customer to login. Has used the data mining technology in the data analysis module, has carried on the reasonable analysis to the data, used the ID3 decision tree to carry on the new user separately to obtain the analysis, the Apriori connection rule carries on the overlapping insurance recommendation analysis, the Birch cluster algorithm has carried on the user segmentation, carried on to these connection rule and the algorithm has studied specifically and realizes.This system's characteristic is uses J2EE to carry on the construction to achieve without the platform, the security, the extension, and has used the data mining technology analytical data, if let the administrative personnels find the high-end customer in the customer value analysis, and realized these customer profit maximization, simultaneously could also cause the supervisory work becomes precise, but order. This system already invested tries the operation stage, and made the actual progress, the service month business volume enhanced 1.8%, customer quantity enhanced 2.3%. |
