| 摘 要： | 为了使复杂装备信息处理系统在进行故障定位过程中耗时最少、成本最低,建立了系统测试序列优化问题的数学模型。基于DPSO-AO*算法的改进，得到信息处理系统的最优测试策略决策树，根据信息处理系统的相关矩阵，按故障概率，随机生成故障，采用相应的测试序列进行测试，最后利用累计测试费用进行比较，从而证明了改进的DPSO-AO*算法正确有效。

| Abstract: | In order to make the complex equipment information processing system take the least time and the lowest cost in the process of fault location,a mathematical model of system test sequence optimization problem is established.Based on the improvement of DPSO-AO* algorithm,the optimal test strategy decision tree of the information processing system is obtained.According to the correlation matrix of the information processing system,the faults are randomly generated according to the probability of failure,and the corresponding test sequences are used for testing.Finally,the cumulative test costs are used for comparison,which proves that the improved DPSO-AO* algorithm is correct and effective. |
