伴随着科学技术的发展,复杂程度逐步提高,传统的人工检测维护技术已经不能满足现代化装备的支持保障需求。并行测试技术可以有效地利用测试资源、合理安排测试任务,从而提高测试资源的利用率、降低测试成本、提高互操作能力。当测试系统的硬件已经确定时,测试系统性能的提高主要依赖于测试任务调度算法的优化,即如何进行测试任务的设计和规划,测试资源的选择及测试任务执行过程中的资源冲突的解决。测试任务调度算法的优劣直接影响到测试系统各方面的性能。并行测试任务调度问题已经成为自动测试系统的一个研究热点。
With the development of science and technology, the complexity is gradually increasing. The traditional manual inspection and maintenance technology can no longer meet the support needs of modern equipment. Parallel testing technology can make effective use of testing resources and arrange testing tasks reasonably, so as to improve the utilization of testing resources, reduce testing costs and improve interoperability. When the test system hardware has been determined, the test system performance improvement mainly depends on the optimization of the test task scheduling algorithm, that is, how to design and plan the test task, the selection of test resources and the solution of the resource conflict in the test task execution process. The advantages and disadvantages of the test task scheduling algorithm directly affect the performance of the test system in all aspects. Parallel test task scheduling problem has become a hot research topic in automatic test system.
