这是参加我校大学生数模竞赛获奖作品，希望能给予其他同学数学模型的概念。本文要解决的是如何分配开关模式，来实现通讯卫星对不同接收站与发送站之间的信息传输，同时，尽量使所耗用的时间最短，或模式数不超过上限。-This is my college students to participate in digital-analog competition winning entries, hoping to give other students the concept of the mathematical model. This article must be resolved are how to allocate the switch mode to achieve communication between the station and sent to different points of information between the transmission, at the same time, as far as possible by the shortest amount of time, or model number does not exceed the ceiling.
