并行自动测试系统分层建模及性能评估方法研究

对于大型的并行自动测试系统,传统的系统组建方法单纯的依靠人工经验使得组建的系统容易发生死锁、资源冲突和饥饿等问题,逐渐不能满足需求。因此,提出了一种新的并行自动测试系统分层化建模方法,指导工程人员快速优化系统设计方案。应用该方法,工程人员只需要使用直观、浅显的UML语言设计测试系统功能结构模型,UML到Petri网模型的映射和Petri网模型对系统的评估等步骤都可以用相应的软件自动实现,简化了人工设计过程,提高了系统组建效率。最后,利用广义随机有色Petri网理论对并行测试系统进行了性能评估,与基于NI公司TestStand软件设计的并行系统进行了对比。

Abstract：

The process of the Parallel Automatic Test System’s construction and design is more complicated than the serial ATS,and it can not be completed depending on the traditional method only based on the people’s experiences because it will bring the deadlock,resources confliction,hunger and so on.A new hierarchical modeling method was proposed to instruct the engineer in the good design of system.In the method,engineer only used the simple UML to design the system’s functional structure model.The UML-Petri map process and the system performance evaluation was finished by software.It made the design process simple and improved the organic efficiency.At last,the generalized coloured stochastic Petri net （GCSPN） was used to evaluate the performance of system and is compared with the parallel system designed by TestStand software.The result embodies the advantages of the hierarchical modeling method.
