摘 要
電廠作為國民經(jīng)濟發(fā)展的基礎支柱產(chǎn)業(yè)之一，其生產(chǎn)效率直接影響著人民生活質(zhì)量水平的提高，而企業(yè)的生產(chǎn)效率一般以數(shù)字形式體現(xiàn)在企業(yè)的各種生產(chǎn)報表中，電廠信息管理系統(tǒng)是快速、精確形成各種生產(chǎn)報表、及時給領導提供決策依據(jù)的有效手段之一。
結(jié)合企業(yè)生產(chǎn)綜合指標的統(tǒng)計要求，在對生產(chǎn)環(huán)境數(shù)據(jù)的分布、采集特點、數(shù)據(jù)統(tǒng)計的復雜關系等各方面進行綜合分析的基礎上，采用目前國際上流行的標準建模語言UML作為標準，對該系統(tǒng)的功能需求作了詳細的分析，闡述了UML建模的基本步驟、UML與關系數(shù)據(jù)庫的映射關系，建立了相應的用例圖、類圖、狀態(tài)圖、協(xié)作圖、組件圖、展開圖等模型圖，使系統(tǒng)的開發(fā)有一個合理的模型基礎，滿足系統(tǒng)的易維護性和擴充性。……
本文從網(wǎng)絡應用的角度對系統(tǒng)進行建模分析，把目前應用和后繼發(fā)展進行兼顧考慮，隨著企業(yè)的發(fā)展，該課題還存在大量的后續(xù)研究工作。

Research of Management Information System of Power Plant Based on UML
Abstract
Power plant is one of the most important industries of the national economic development, and its productivity takes direct effect on the people’s living standard. The output forms of the enterprise play a great role in its productivity. The most effective means to manage the information of the enterprise is to use computer, which can help managers to finish the production report forms quickly and exactly, and can benefit to the leader for decision-making.
This paper analyzes the data characteristics of the enterprise, including data distribution, data-collecting mode, and the complex data-calculating relations based on the statistical requirements. It analyzes the functional requirements of the system in detail with UML, and describes the basic steps of UML modeling and the mapping relationship between the UML and the relation database. In addition, we construct use case diagram, class diagram, state diagram, collaboration diagram, component diagram, deployment diagram and other model diagrams. It is becoming more maintainable and extensible to manage the system based on these reasonable modeling foundations….
We analyze the system modeling from the view of network application, considering the current application and future evolution. However, there is still a lot of research work to be done with the development of enterprise.

Key Words：criteria, UML, relation database, diagram
