提出一种改进差分进化算法(IDE),以解决系统可靠性冗余分配问题.在罚函数法的基础上,对约束处理方法进行改进.新约束处理方法在搜索过程中不需要在每一步都计算惩罚函数值,加快了寻优速度.具有良好的通用性,可以引入到其他智能优化算法中.将改进的算法用于求解4类典型的系统可靠性冗余分配问题,实验结果表明了所提出的改进算法具有很好的寻优精度和收敛速度.
This paper proposes an improved differential evolution algorithm (IDE) to solve the problem of redundant allocation of system reliability.On the basis of the penalty function method, the constraint processing method is improved.The new constraint processing method does not need to be in every step The penalty function value is expedited and the optimization speed is accelerated.It has good generality and can be introduced into other intelligent optimization algorithms.The improved algorithm is used to solve the four types of typical system reliability redundancy allocation problems.The experimental results show that The proposed improved algorithm has good precision and convergence speed.
