【摘要】:随着信息技术的发展,信息化正在从简单产品的单项应用向复杂产品的集成优化发展,从战术层面开始上升到战略层面,借助信息技术对现有数据进行统计、分析和挖掘,使其转变为企业的决策信息,从而提高企业的竞争优势是企业信息化发展的需要。当前如何提高港口企业的运作效率、库场占有率,提高港口企业的计划、调度信息准确性,合理安排港口货运计划、生产运作,已成为港口企业管理者共同关注的课题。而这些目标的实现依赖于对港口货运数据全方位、多维度的深入统计分析,从而挖掘数据背后隐藏的有价值的决策信息。当前港口企业货运统计仅局限于对固定报表单纯的数据查询、数据罗列,上报集团的报表数据也是各分公司统计数据的简单汇总,不能实现跨系统的、多维度的综合分析、预测决策功能,不能实现有效的统计分析,而决策支持系统在这方面能恰到好处的发挥作用。 本文基于当前港口货运统计现状基础上,提出建立港口货运决策支持系统,从而实现港口货运统计分析需求。论文主要工作如下:首先详细分析总结了当前港口货运统计的现状及存在问题;其次进行港口货运统计的需求分析,在此基础上提出港口企业决策支持系统的架构设计及使用的关键技术,并以广州港集团港口集疏运统计分析为例说明港口货运统计决策支持系统的分析模型及数据模型设计;最后以广州港集团集疏运统计为例,运用Cognos智能报表分析工具进行了系统实现。
[Abstract]:With the development of information technology, informatization is developing from the single application of simple products to the integration optimization of complex products, from tactical level to strategic level, with the help of information technology to statistics, analysis and mining of existing data. It is necessary for the development of enterprise informatization to change it into enterprise decision information and improve the competitive advantage of enterprise. At present, how to improve the operation efficiency of the port enterprise, the occupation rate of the warehouse, the plan of the port enterprise, the accuracy of the information scheduling, the reasonable arrangement of the port freight plan and the production operation, have become the common concern of the managers of the port enterprise. The realization of these goals depends on the comprehensive and multi-dimensional statistical analysis of port cargo data, so as to mine the valuable decision-making information hidden behind the data. At present, the port enterprise cargo statistics is limited to the simple data query of the fixed report forms, the list of data, the report data reported to the group is also a simple summary of the statistical data of each branch, and it cannot realize the comprehensive analysis of cross-system and multi-dimension. Predictive decision function can not achieve effective statistical analysis, and decision support system can play a proper role in this aspect. Based on the current status of port cargo statistics, this paper puts forward the establishment of port cargo decision support system, so as to meet the demand of port cargo statistics analysis. The main work of this paper is as follows: firstly, the status quo and existing problems of port cargo statistics are analyzed and summarized in detail; secondly, the demand analysis of port cargo statistics is carried out. On this basis, the key technologies of the structure design and application of the port enterprise decision support system are put forward, and the analysis model and data model design of the port freight statistics decision support system are illustrated by the statistical analysis of the port gathering and distribution of Guangzhou Port Group. Finally, taking Guangzhou Port Group as an example, the Cognos intelligent report analysis tool is used to realize the system.
