港航EDI信息增值原型系统的开发

Developing the Value-added Information System of Port and Shipping EDI

着重对港航EDI(ElectronicDataInterchange)信息增值原型系统的开发进行了系统的研究,内容主要包括:港航EDI信息增值系统的功能界定、港航EDI信息转换与组织的基本原理与应用以及港航EDI信息增值原型系统的实现.从研究中,我们发现:1.基于港航EDI源信息的数据挖掘,可以实现集装箱市场分析、集装箱运价指数编制及分析、集装箱运营管理优化等信息增值功能.2.港航EDI信息源基本覆盖了集装箱运输流程中的各个业务环节,但比较分散,因而必须对源数据进行二次转换,形成元信息和增值信息.3.港航EDI信息增值原型系统的体系结构是N层的B/S结构,具体实现技术以PB为主.

This paper gives a systematical study on developing the prototype of the value-added information system of the port and shipping EDI(Electronic Data Interchange). It includes: the function defining of the value-added information system, the basic principle and application of EDI information organizing and transforming; the realization of the prototype of the value-added information system of port and shipping EDI. The conclusions we have drawn are as follows: 1. With the data digging from the rough date transferred through the port and shipping EDI platform, so many functions of the value-added information can be realized such as container market analyzing, the compiling and analyzing of container freight index and the optimization pf the container management, etc. 2. The information transferred through the current port and shipping EDI platform cover all of the sections of the container transportation flow. As the rough data are out of the order, it is necessary to transform the rough data into primary data and value-added information.3. The system architecture of the value-added information system of port and shipping EDI is B/S with N layers, and the developing technology is PB as major.
