1. 項目介紹
設計一個多線程模擬銀行業務辦理程序:
-
業務時間
模擬客戶可以隨機辦理銀行提供的8種業務中的一種(基准時間自定義),辦理時間規划為:
業務 | 業務序號 | 辦理時間范圍 |
---|---|---|
取款 | 1 | 0.5-1.5r |
存款 | 2 | 0.5-1.5r |
繳納罰款 | 3 | 1.2-2.0r |
開通網銀 | 4 | 5.0-8.0r |
繳納水電費 | 5 | 1.5-2.0r |
購買基金 | 6 | 2.0-3.0r |
轉賬匯款 | 7 | 3.0-4.0r |
個貸還款 | 8 | 2.0-4.0r |
r=基准時間
-
服務窗口
程序模擬多個窗口服務,窗口服務具有一定的差異化,窗口開放情況:
窗口類型 | 可辦理業務 | 辦理客戶范圍 |
---|---|---|
A 類窗口 |
1,2,3,4,5,6,7,8 |
所有客戶 |
B 類窗口 |
1,2,4,5,7 |
所有客戶 |
C 類窗口 |
1,2,3,4,5,6,7,8 |
VIP 優先(所有客戶) |
模擬開放為A類:B類:C類=1:2:1
-
模擬客戶
客戶區分普通
客戶與VIP
客戶
客戶模擬需隨機產生
-
展示客戶列表
模擬時間:8:00-17:00
結束營業后,打印當天客戶列表
客戶列表包含:客戶名稱
、客戶到達時間
、客戶辦理業務類型
、客戶所用時間
-
統計數據
當天客戶平均業務辦理時間(客戶辦理時間:到達——完成
)
當天客戶所有辦理業務中的所占比例
-
仿真性要求(評優要求)
參數化設定當天客戶辦理業務的比例(比如設置業務1占20%)
提供窗口開放建議:根據當日的業務情況給出建議的A、B、C
類三窗口數量,達到與基准日一致的客戶服務時間
2. 考核要求
-
基本要求:
(1)提交規范的代碼
(2)系統包含多線程
、線程互斥
、線程同步
(3)業務類型使用Enum類型

(3)實現用戶模擬
(4)實現窗口分配模擬
(5)仿真的方法(設計仿真的方法)

7. 測試用例
-
線性隨機分配函數證明:
(1)設計方法證明隨機分配的有效性與可靠性
(2)Java中的Math.random()是線性均勻的
(3)根據自定義的數據范圍對生成數的百分比進行控制
(4)下圖證明了方法可以控制隨機數生成的比例可以固定在“3:7”,且保持了隨機性

-
開業操作:

-
隨機生成造成擁堵,進行排隊:
(1)VIP隊列:根據VIP客戶
到達時間進行取號排序。
(2)普通隊列:根據普通客戶、VIP客戶
到達時間進行取號排序。

-
結束營業操作,包含:
(1)結束營業時間(客戶生成方法在17:00前隨機生成,排隊造成的業務延期將會延長上班時間,延后結束營業時間)
(2)今日服務人數
(3)VIP與普通客戶的占比
(4)各業務辦理的占比
(5)累計業務服務時間、各類窗口業務服務時間占比、人均業務服務時間
(5)累計等待時間、各類窗口等待時間占比、人均等待時間

-
建議窗口數量,分析方面:
(1)根據VIP占比
(2)根據B窗口不支持業務
(3)根據網銀業務占比(網銀業務時間占比大)
(4)根據客戶平均等待時間
(5)以下是多情況運行截圖




-
客戶列表:
(1)總客戶列表,無序,按照排到的業務順序
(2)A類窗口客戶列表,有序,按照取號碼升序
(3)B類窗口客戶列表,有序,按照取號碼升序
(4)C類窗口客戶列表,有序,按照取號碼升序





8. 總結
-
學習:
(1)新接觸了Enum類,學習並掌握其使用方法
(2)第一次嘗試使用時間流動方法,根據秒來進行操作
(3)使用Math.Random來進行固定比例的生成
(4)嘗試了新的方法來加鎖與解鎖
-
鞏固:
(1)鞏固了時間的計算與調用
(2)多次使用HashMap與ArrayList,並調用方法
(3)類的創建、定義與調用的鞏固
(4)結合了OS系統原理內容,分析銀行叫號、分配業務、辦理的同步與互斥
-
缺漏:
(1)時間的定義還需完善
(2)互斥的部分調試時間較長
(3)分析窗口不夠細,需要完善
(4)打印格式、代碼模塊比較亂
