摘要
三峡工程生态与环境信息系统具有多学科、多层次、综合性特点,业务流程建模是建设这种大型复杂系统的有效手段。在分析三峡监测系统管理现状及业务构成的基础上,将三峡信息系统中业务划分为两大类,并采用两种不同的方法实现了系统的业务流程建模。对于管理型业务流程应用RATIONALROSE的UML的活动框图建模。针对系统中复杂生态环境业务流程,通过综合常用建模方法的优势,改进了通用业务流程描述元素,形成了一种新的业务流程建模方法,该方法运用面向对象的设计思想,采用逐层细化的策略,从数据、过程、功能与信息表达等方面对业务模型进行定义和描述,对专业人员来讲操作方便、简单。文中还给出了两种方法的建模过程、实例,以及系统相应的实现界面。实验证明,该方法在三峡工程生态与环境信息系统的业务流程分析中都得到了较好的应用效果。
The eco-environmental monitoring information system of Three Gorges project is multi-subject,multi-level and comprehensive.And business process modeling is an effective tool for this kind of large and complex system.In the paper,business processes in information system of Three Gorges are divided into two types and we adopt different methods to model these processes.For administrative business processes,we adopt activity diagram of UML.For complex eco-environmental business processes, we take advantage of common modeling methods,adjust descriptive elements and create a new method for business process.This method adopts strategy of object oriented design and ＂layer-subdivided＂,describes business process from the aspects of data,process,function and information expression etc.So it is convenient and easy for professionals.It proved that the business process modeling is useful and convenient for system analysis of information system of Three Gorges.
