摘要
针对现有诊断策略优化方法中因假设测试是可靠检测而容易造成诊断策略优化结果不可靠,进而误诊费用增高的问题,提出了一种考虑测试可靠度的诊断策略优化方法。首先对诊断策略优化问题进行了描述,并在此基础上提出了考虑测试可靠度的诊断策略优化模型;然后通过设计考虑测试可靠度的启发函数对准深度算法进行改进,并采用该算法对优化模型进行求解;最后通过实例验证论文方法的有效性。仿真结果表明,考虑测试可靠度的诊断策略优化方法可以有效平衡测试代价和测试可靠度的矛盾,改善诊断策略优化结果不可靠的问题。
In this paper,a method of effectively choosing tests with high reliability is proposed,which is based on the prob⁃lem that the test optimization is not accurate and the misdiagnosis cost is increased,due to the assumption that the test is a reliable test in the traditional diagnosis strategy optimal method.First,the diagnosis strategy optimization problem is described.Based on this,a diagnostic strategy optimal model considering test reliability is proposed.Then,improved quasi-depth first search(IQDFS)algorithm considering test reliability is used to solve the problem.Finally,the effectiveness of the proposed method is verified by an example.The simulation results show that the diagnostic strategy optimization method considering the reliability of tests can effective⁃ly balance the contradiction between the test cost and the test reliability,and improve the unreliable results of the diagnosis strategy.
