中文摘要:

      建立了n路多通道压力测试系统的广义随机Petri网（GSPN）模型，利用模型的可达图和MC链分析了GSPN模型的基本性能；推导出了压力测试系统的测试性能的数学公式，测试性能包括各部分的利用率、单位时间内的激发次数、系统时间延迟；并且分析了测试系统各部分之间的相互影响。经过实验验证，证明了该模型的正确性。

英文摘要:

      A GSPN model of multi-channel system of pressure testing is established,the performance of the GSPN model by using the model’s MC chain and reachability graph is analyzed.Mathematical formulas of test perfonmance is derived,which including utilization rate of all the parts of the pressure testing system number of excitation in per second,system time delay.And the interact of all the parts of testing system is analyzed.The model has been proved to be corrected through the experimental results.
