简介：在这篇论文，我们与工作假期和假期打断学习M/M/1队列。工作假期最近被介绍，在哪个期间服务者能仍然以更低的率在原来的进行中的工作上提供服务。同时，我们介绍一个新policy:the服务器罐头一旦系统的一些索引例如顾客的数字，在假期时期完成某个值，从假期回到正常工作水平。没有完成假期，服务者可以从假期回来。如此的政策被称为假期打断。我们连接提及的上面二条政策并且假设如果在假期时期期间在在服务结束以后的系统有顾客，服务器将回到正常工作水平，嗨伪出生和死亡过程和矩阵几何的解决方案方法称为，我们为顾客和等待的时间的数字获得分布和随机的分解结构并且提供系统的一些索引。

简介：在这笔记，当再审时间，服务时间和假期时间是任意的时，我们与服务者假期考虑一个M/G/1再审队列分布式。在在静止政体的系统的顾客的数字的分发以产生功能被获得。下次，我们给如此的分发的交通拥挤近似。我们证明系统尺寸能被分解成二个随机的变量，没有假期，其一个对应于平常的M/G/1FIFO队列的系统尺寸。如此的一个随机的分解性质为兴趣的表演措施的计算是有用的。最后，我们解决假期和再审政策的最佳的控制的简单问题。

简介：囚徒困境是研究合作策略演化的重要工具,重复囚徒困境下的博弈者可以通过合作实现长期利益的最大化。采用生态演化模拟实验的方法研究在重复囚徒困境中初始环境设定的噪音水平和个体间交互频次对博弈策略演化的影响。研究结果表明,噪声水平和个体间交互频次对最终系统中优胜的博弈策略有决定性作用,这说明环境的初始设定条件是影响博弈策略演化的重要因素。
