摘　　要：为了优化企业信息系统的体系结构,基于时间性能研究了企业信息系统的形式化表达———对象知识网结构的优化方法。通过对象知识网的知识点间关系的表达,对不同类型知识点结构的时间性能进行了讨论,提出了基于二叉树的知识点表达式的表示方法,解决了优化算法的编码问题,采用基于改进的免疫遗传算法,对对象知识网的结构进行优化,并通过算例对提出的优化方法进行说明和验证,获得了优化的对象知识网体系结构,同时为基于时间性能的企业信息系统结构优化奠定了理论基础。To optimize the structure of enterprise information systems, this paper dealed with a new approach to optimize the structure of object-based knowledge mesh （OKM） based on time performance, which was the formal representation of enter- prise information systems. Firstly, it discussed the relationships between knowledge points, and discussed time performance of knowledge point relationships. Then, it proposed the representation of knowledge point construction based on the binary tree, which solved the coding problem of optimization. And then, based on the improved immune genetic algorithm, it optimized the structure of OKM. Finally, it exemplified and verified the new approach, and obtained the optimized the structure of OKM, which laid the foundation for performance optimization of enterprise information systems.
