论文摘要
随着互联网路由器的快速发展，其主板的复杂性一直在急剧增长。高可靠性要求使测试案例的数量呈指数增加，这成为阻止生产效率进一步提高的瓶颈。在这项工作中，我们开发了一种新的优化方法，分为两个主要步骤，以大大减少测试时间并提高测试效率。在第一步中，它在确保覆盖失败的同时，优化了测试案例的选择。在第二步中，最佳的测试用例是最大程度地安排了主板测试的效率。研究了数值实验，以说明所提出方法的有效性。结果表明，可以选择满足10％测试时间减少需求的测试用例的最佳子集，并且可以通过测试案例测序来提高计划序列的有效性指数超过75％。此外，我们的方法可以自我调整新的故障数据，该数据实现了板测试用例的自动配置。
With the rapid development of internet Router, the complexity of its mainboard has been growing dramatically. The high reliability requirement renders the number of testing cases increasing exponentially, which becomes the bottleneck that prevents further elevation of the production efficiency. In this work, we develop a novel optimization method of two major steps to largely reduce the testing time and increase the testing efficiency. In the first step, it optimizes the selection of test cases given the required amount of testing time reduction while ensuring the coverage of failures. In the second step, selected test cases are optimally scheduled to maximize the efficiency of mainboard testing. A numerical experiment is investigated to illustrate the effectiveness of the proposed methods. The results show that the optimal subset of the test cases can be selected satisfying the 10% testing time reduction requirement, and the effectiveness index of the scheduled sequence can be improved by more than 75% with test case sequencing. Moreover, our method can self-adjust to the new failure data, which realizes the automatic configuration of board test cases.
