基于组件装配的分布式可重构企业信息系统

Distributed Reconfigurable Enterprise Information System Based on Component Assembly

在深入分析企业中经常变化的内容和基本不变的内容的基础上 ,指出业务流程的变化是引起企业信息系统重构的原因。根据功能体的“自治”、“协作”性将 BPR分为功能体内重构和功能体间重构两类 ,同时论证了子功能体的变动独立于功能体 ,功能体包的变动独立于整个信息系统两种独立性。在此基础上 ,提出了系统的重构策略 :采用面向对象的方法建立企业独立于具体业务流程的功能模型 ,通过对功能模型中相应功能体的修改 ,实现信息系统的重构。并通过一个库存管理的实例 ,验证了文中提出的重构方法是切实可行的。

Based on analyzing variant contents and constant contents in the enterprise, the variance of business processes is the reason to reconfigure the enterprise information system. According to the 'autonomy' and 'cooperation' of function body, BPR is classified into the reconfiguration in the function body and one between a function body and others; two kinds of independences are presented: the variance of sub function body is independent of the function body, the variance of function body is independent of the whole enterprise information system. Based on those analysis, the reconfigurable strategy for enterprise information system is presented as follows: creating the function model independent of the specific business process of enterprise using object oriented method, reconfiguring enterprise information system through modifying the function bodies in the function model. Finally, the reconfigurable method is proved to be feasible by using a reconfigurable example about inventory management.
