项目名称：电梯调度系统
经过了两个多星期的结对开发过程，我们的电梯调度系统有了一个初步的面貌。现版本的调度系统和最初的设想还是有很大的区别的。最初的设想是有一个整体调度系统，每当乘客发出一个请求，调度系统就通过这个计算来为这个请求分配一部电梯。在实践的过程中发现这样不可行，复杂度很高，这个问题能有多复杂就有多复杂。后来通过实际调研和自己思考，决定将问题简单话，即四部电梯只会沿着自己的方向来运行，某一层有顾客请求就停下。而调度程序只为处于ready状态的电梯发出命令。通过这样的思路来简化问题，从而实现了电梯的运行。
在电梯的实现过程中，使用了线程的技术。将每个电梯对象的run方法封装成一个线程，这样四部电梯就能不受互相影响的同时运行，并且接受调度。在编程环境上我们选择使用visual studio 2010 下的C#，实现了界面的设计。目前项目尚有一些不足之处，如没有一个整体观察电梯运行的界面和人数检测，我们会尽力将这些在以后进行完善。
