摘要: 针对多目标优化的可重构性指标分配问题,给出了一重和二重可重构性指标的计算方法。结合多目标优化特点和可重构性指标的定义建立了可重构性指标分配的多目标优化模型。在此基础上提出了一种多评价函数法,用于系统可重构性指标分配,该方法对相互冲突的多个目标建立不同的评价函数,通过在可行解内协调得到最优化结果,最后将其应用于串联系统进行仿真,并与线性加权和法的结果作比较,结果显示基于多评价函数的可重构性指标分配方法更具有效性。

Abstract: The paper aims to find a reasonable solution to the problem of reconfigurability allocation for the multiobjective optimization. The concept and the computing method of reconfigurable degree for the reconfigurable system considering component failure are proposed. Combining the theory of multiobjective optimization and the definition of reconfigurability, allocation model in general is proposed. We obtain the method solving the problem of optimization allocation for conflicting objectives, in which different evaluation functions for conflicting objectives are established. Then, the optimal result is concluded by weighing of the feasible results. As the representative multiobjective optimization method, the weighted sum method is compared with the proposed method. The simulation results demonstrate superiority of the proposed method.
