中文摘要:

针对传统同构系统对于共模干扰的影响容易引发并发故障问题,设计一种容错能力更强的异构冗余系统.从图论中得到启发,结合多目标遗传算法,给出异构系统设计的原理与流程,构造了异构度更高的冗余系统,从而增强了系统的容错性能.以D触发器作为设计实例,结果证明了基于多目标进化设计的异构电路所组成的异构系统具有更好的容错能力.

英文摘要:

Aiming at eliminating the simultaneous fault of traditional same-structure system caused by common mode interference, different-structure redundant system is designed to get better fault-tolerance ability. Principle and process of different-structure are given based on the knowledge of graph and multi-objective genetic algorithm, then in order to improve fault-tolerant capability, redundant system is designed whose different-structure degree is higher. D flip-flop is taken as an example. The experimental results prove that the performance of different-structure system which is composed of different-sturcture circuits evolved by multi-objective genetic algorithm can obtain better fault-tolerant capability.
