A Genetic Algorithm-Ant Colony Algorithm(GA-ACA),which can be used to optimize multi-Unit Under Test(UUT)parallel test tasks sequences and resources configuration quickly and accurately,is proposed in the paper.With the establishment of the mathematic model of multi-UUT parallel test tasks and resources,the condition of multi-UUT resources mergence is analyzed to obtain minimum resource requirement under minimum test time.The definition of cost efficiency is put forward,followed by the design of gene coding and path selection project,which can satisfy multi-UUT parallel test tasks scheduling.At the threshold of the algorithm,GA is adopted to provide initial pheromone for ACA,and then dual-convergence pheromone feedback mode is applied in ACA to avoid local optimization and parameters dependence.The practical application proves that the algorithm has a remarkable effect on solving the problems of multi-UUT parallel test tasks scheduling and resources configuration. 相似文献

构建了并行测试系统(PATS)故障诊断效能评价指标体系,针对该指标体系在评价过程中存在的不确定因素,结合神经网络和模糊理论的优点,提出了基于神经网络的模糊综合评价方法(FCEANN);详细给出了FCEANN的求解算法及步骤,结合实例进行仿真实验并与专家评价结果进行比较,对影响模型预测精度的因素进行了分析;仿真结果表明,基于BP神经网络和Elman神经网络的FCEANN均能够很好地模拟专家评价的全过程,能够准确地对PATS的故障诊断效能指标进行评价;并将两种神经网络的仿真结果进行了比较,结果表明,Elman神经网络得到的仿真结果精度更高. 相似文献
