说明: 务器端基于select I/O模型。为防止程序界面阻塞,有一个子线程用于不断接收socket并select其中的处理。客户端只有一个线程函数,不过其利用率很高,可用于远程目录交换,请求文件大小,创建若干线程来下载文件。文件传输有上传和下载,还有对等传输,这个项目中,传输文件具体指下载。(Client server based on select I/O model. Programming interfaces in order to prevent obstruction, there is a sub-thread for receiving socket and select which treatment. There is only one client thread function, but its utilization very high, can be used for remote directory exchange, request the file size, create a number of threads to download the file. File transfer are uploading and downloading, as well as peer-to-peer transmission, this project, the specific means to transfer files to download.)

1、首先,我们分析调查到的数据,发现学生流符合泊松分布,服务时间符合指数分布,由此我们的模型就变成了排队论中典型的MM
模型,根据MM
模型中的各效率指标的公式,我们可得到学一食堂拥挤情况的各方面数据。
2、根据模型求解得到的数据,我们对模型进行了更精确的量化分析。我们发现,解决本模型的关键就在于分析顾客平均排队时间,我们对其与窗口数之间的关系进行了拟合,并就两者之间关系进行了灵敏度分析。
3、针对窗口数与顾客平均排队时间之间的关系,我们从经济学的角度进行了分析,即比较增加窗口后成本的增加量与减少排队等待时间所带来的收益之间的大小关系。
