結對開發項目-電梯調度系統

小組成員：馬翔 & 胡佳奇

項目名稱：電梯調度系統

      經過了兩個多星期的結對開發過程，我們的電梯調度系統有了一個初步的面貌。現版本的調度系統和最初的設想還是有很大的區別的。最初的設想是有一個整體調度系統，每當乘客發出一個請求，調度系統就通過這個計算來為這個請求分配一部電梯。在實踐的過程中發現這樣不可行，復雜度很高，這個問題能有多復雜就有多復雜。后來通過實際調研和自己思考，決定將問題簡單話，即四部電梯只會沿着自己的方向來運行，某一層有顧客請求就停下。而調度程序只為處於ready狀態的電梯發出命令。通過這樣的思路來簡化問題，從而實現了電梯的運行。

      在電梯的實現過程中，使用了線程的技術。將每個電梯對象的run方法封裝成一個線程，這樣四部電梯就能不受互相影響的同時運行，並且接受調度。在編程環境上我們選擇使用visual studio 2010 下的C#，實現了界面的設計。目前項目尚有一些不足之處，如沒有一個整體觀察電梯運行的界面和人數檢測，我們會盡力將這些在以后進行完善。
