摘要
针对网络环境多变的情况,提出了一种动态自适应系统的理论模型.通过对自适应系统结构功能的抽象,描述了系统内核与传感器的形式化定义,讨论了网络构件软件系统在变化环境中网络构件进化、变异和复制逻辑过程的特点,提出了以进化算法为基础的改善系统稳定性和高效性的变异算法.通过测试动态自适应算法在复杂环境中的运行情况,结果表明进化变异算法能够有效提高系统的性能和稳定性,使基于网络构件的软件系统能够适应复杂多变的网络环境.
A self-healing system model for unstable network environment was presented. The abstract structural function of the self-healing system was described and formally defined as the heart and sensor of the system. Dynamics of evolution, mutation and multiplication were discussed as algorithm for high performance and fault tolerance. The experimental results show that the dynamic self-healing system is adaptable for use in complex and variable environment.
