通过对主从系统的数学建模并利用matlab随机试验模拟，研究主从多机通信系统的可靠性，以及采用不同措施预防和解决故障的可行性和统计规律。包括实验报告和源代码- Though the mathematical modeling of the master-slave system and the random experiment with Matlab, we tried to research about the reliability of the system with or without different methods to prevent and solve the failure of the system, therefore we find some statistical regularity.
