【摘要】：信息技术在当今企业生产活动中的作用越来越重要,实现它的主要方式是企业资源规划(Enterprise Resource Planning)。ERP系统要具有相当的灵活性和扩展性,才能帮助企业在瞬息万变的市场中立于不败之地。构件技术能提高软件的复用度,软件系统对构件进行替换,修改,升级也能让系统的灵活性提升不少。为了适应社会生产活动中灵活多变的需求,提升ERP系统的柔性,降低开发成本,提高开发效率,设计了基于构件的可重构ERP系统架构。它主要包括模型转换子系统,构件库,以及构件搜索组装子系统。其中模型转换子系统运用转换规则把UML状态图转化为构件行为描述信息;构件库把所有刻面分类关键词按照层次关系建立一棵树,树的叶节点值对应构件术语信息,并以术语信息作为词表单词建立倒排索引给构件检索提供支持;构件检索组装子系统在对构件进行检索时设计了两步检索策略:基于刻面分类描述的初步检索和基于构件行为描述的二次检索,而其中针对复合构件的检索,会分解复合构件得到需要查找的原子构件,再利用改进的粒子群算法选取最优原子构件组,并按照行为描述中的操作关系组装成为符合要求的复合构件。通过实验实现基于构件的可重构ERP系统框架中三个子系统,并以一个业务过程验证了此框架能基于构件完成ERP系统重构。
[Abstract]:Information technology plays an increasingly important role in the production activities of today's enterprises. The main way to realize it is to have considerable flexibility and expansibility in the ERP (Enterprise Resource Planning). ERP system. In order to help enterprises in the rapidly changing market in an invincible position. Component technology can improve the degree of software reuse, software system to replace components, modify, upgrade can also improve the flexibility of the system a lot. A component-based reconfigurable ERP system architecture is designed in order to meet the flexible needs of social production activities, improve the flexibility of ERP system, reduce the development cost and improve the development efficiency. It mainly includes model transformation subsystem, component library and component search and assembly subsystem. The model transformation subsystem uses the transformation rules to transform the UML state diagram into component behavior description information, and the component library sets up a tree according to the hierarchical relationship of all facet classification keywords, and the leaf node value of the tree corresponds to the component terminology information. The inverted index based on the term information is used to provide support for component retrieval. The component retrieval assembly subsystem designs a two-step retrieval strategy: the initial retrieval based on facet classification description and the secondary retrieval based on component behavior description. The atomic components needed to be searched are decomposed and the optimal atomic components are selected by using the improved particle swarm optimization algorithm. The composite components are assembled according to the operational relations in the behavior description. Three subsystems in the component-based reconfigurable ERP system framework are implemented experimentally, and a business process is used to verify that the framework can complete the reconfiguration of the ERP system based on the component.
