基于面向对象技术的火电厂经理信息系统分析

Object-Oriented Analysis of EIS in Fuel Power Plants

目前 ,电力企业正在进行信息化进程 ,能对高层管理者提供决策支持的经理信息系统 (EIS)是电力企业信息系统开发中的一个研究热点。采用传统的结构化分析设计方法开发EIS时 ,有很大的不足 ,文中以一个火 (力发 )电厂为实例 ,利用面向对象 (OO)方法来进行经理信息系统的系统分析。首先介绍了经理信息系统需求分析方法 ,描述了火电厂经理信息系统的问题空间 ,确定了用户需求 ;然后叙述了火电厂经理信息系统对象模型的建立过程 ,包括对象的标识、对象属性的标识、对象方法的标识。

Presently,With the progress of information management in power supply enterprises,Executive Information System(EIS) becomes a hot research of the development of electric power enterprise information systems.Traditional structured analysis and design mcthod has quile a few disadvantages.The object-oriented analysis method is introduced into the system analysis of a fuel power plant's EIS(executive information system) in this paper. Firstly, the requirement analysis method of EIS is illustrated together with the description of its problem space and customer requirements.Then the process of building the object model is described,including the identification of objects,object attributes and object methods,messaging mechanism,implementation of system level behavior and sub ystem partition.
