我想模擬一個生產系統。爲了解釋我打算簡要地做些什麼，我將創建一個小組，在這個小組中我將有一些表格來保存數據（針對幾個工作站和工作類型的特性（見下圖））。當我運行它時，這些值應該被存儲以供進一步處理。如何處理TreeMaps？我可以只使用一個TreeMap來存儲多個項目的值嗎？
關於前一個問題，我用樹狀圖來存儲這些值推薦，所以我創建類似：
Station[num][type][avg_time][posx][posy][state]
Part[num][type][state]
繼承人是到目前爲止我的代碼：

int wHeight = appletSize.height;
int wWidth = appletSize.width;

setSize(ww,wh);

的DrawRectangle.java代碼是在這裏只是爲那些誰可能要編譯的代碼，但沒有任何實際問題爲止。 TMap.java是我創建地圖的地方，並且有處理數據的方法。一切工作正常，我的問題是這樣的：
最有可能的，模擬的時候，我將有一個以上的站，所以我需要存儲的信息在這樣一個問題：
Station[num][type][avg_time][posx][posy][state]
Station[1][1][5][100][20][0]
Station[2][2][7][200][20][0]
Station[3][3][4][300][20][0]
事情是，當我把新的數據到樹形圖，它會覆蓋原有的數據存儲，所以如果我添加信息的兩倍，輸出會到來：
Now the tree map Keys: [avg_time, num, posx, posy, type]
Now the tree map contain: [5, 1, 100, 20, 1]
Now the tree map Keys: [avg_time, num, posx, posy, state, type]
Now the tree map contain: [7, 2, 200, 20, 0, 2]
模擬將被限制在6個工作站點，所以我的問題是，處理這個問題的最佳做法是什麼？我唯一能想出的就是創建6個TreeMaps，並只使用那些需要的，但我確信必須有一種更簡單，更高效的方式來存儲數據。
在此先感謝您的幫助！
