摘要
针对产品维护、维修与大修系统在性能测试过程中存在的性能缺陷难以定位和测试次数众多的问题,提出一种面向维护、维修与大修领域的分布式系统性能测试方法。该方法以决策树方法为基础,对性能测试过程中的测试用例生成、测试用例运行和性能缺陷定位进行了具体的描述。通过在决策树中的扩散策略部分引入二分法和黄金分割法,进一步有效地减少了测试次数。将该性能测试方法应用在维护、维修与大修状态监测平台上,验证了方法的可行性和有效性。
Due to lack of effective methods to position performance deficiencies and reduce the number of tests in Ma intenance, Repair and Overhaul/Operations （MRO） domain, a method of performance test for distributed system o riented to MROwas proposed. Based on the decision tree method, a detailed description of test case generation, test case running and positioning deficiencies in performances across the process of testing were given. In the diffusion strategies part of the decision tree, the number of tests was reduced effectively by introducing the dichotomy and the golden section method. The feasibility and effectiveness of the proposed method were verified through applying it on the condition monitoring platform of MRO.
