1. 项目介绍
设计一个多线程模拟银行业务办理程序:
模拟客户可以随机办理银行提供的8种业务中的一种(基准时间自定义),办理时间规划为:
业务 |
业务序号 |
办理时间范围 |
取款 |
1 |
0.5-1.5r |
存款 |
2 |
0.5-1.5r |
缴纳罚款 |
3 |
1.2-2.0r |
开通网银 |
4 |
5.0-8.0r |
缴纳水电费 |
5 |
1.5-2.0r |
购买基金 |
6 |
2.0-3.0r |
转账汇款 |
7 |
3.0-4.0r |
个贷还款 |
8 |
2.0-4.0r |
r=基准时间
程序模拟多个窗口服务,窗口服务具有一定的差异化,窗口开放情况:
窗口类型 |
可办理业务 |
办理客户范围 |
A 类窗口 |
1,2,3,4,5,6,7,8 |
所有客户 |
B 类窗口 |
1,2,4,5,7 |
所有客户 |
C 类窗口 |
1,2,3,4,5,6,7,8 |
VIP 优先(所有客户) |
模拟开放为A类:B类:C类=1:2:1
客户区分普通 客户与VIP 客户
客户模拟需随机产生
模拟时间:8:00-17:00
结束营业后,打印当天客户列表
客户列表包含:客户名称 、客户到达时间 、客户办理业务类型 、客户所用时间
当天客户平均业务办理时间(客户办理时间:到达——完成 )
当天客户所有办理业务中的所占比例
参数化设定当天客户办理业务的比例(比如设置业务1占20%)
提供窗口开放建议:根据当日的业务情况给出建议的A、B、C 类三窗口数量,达到与基准日一致的客户服务时间
2. 考核要求
(1)提交规范的代码
(2)系统包含多线程 、线程互斥 、线程同步
(3)业务类型使用Enum类型
(4)程序所有存储都需要使用集合 ,不能使用数组
(1)程序整体结构设计
(2)包含有营业过程管理:开门 、关门 、营业分配过程
(3)实现用户模拟
(4)实现窗口分配模拟
(5)仿真的方法(设计仿真的方法)

5. 类职责划分与核心代码
(1)枚举类定义(与普通类不一样,需要提前固定)
public enum Bank_Business_Enum {
//实际类一般采用大写
WITHDRAW("取款服务",1,0.5,1.5,20.00),
DEPOSIT("存款服务",2,0.5,1.5,15.00),
PAY_FINE("缴纳罚款",3,1.2,2.0,10.00),
OPEN_ONLINE_BANK("开通网银",4,5.0,8.0,10.00),
PAY_WATER_ELECTRICITY("缴纳水电",5,1.5,2.0,10.00),
PURCHASE_FUND("购买基金",6,2.0,3.0,10.00),
REMITTANCE("转账汇款",7,3.0,4.0,15.00),
REPAYMENT("个贷还款",8,2.0,4.0,10.00)
(2)数据定义
//创建数据定义
private String Business_Name;//业务名
private int Business_ID;//业务ID
private double Business_MinTime;//默认业务最小时间范围
private double Business_MaxTime;//默认业务最小时间范围
private double default_proporion=0;//默认定义占比
private double proportion=0;//实际占比
(3)方法构造器
//银行业务枚举类方法创建
Bank_Business_Enum(String Business_Name,int Business_ID,double Business_MinTime,double Business_MaxTime,double Default_Proporion){
this.Business_Name=Business_Name;
this.Business_ID=Business_ID;
this.Business_MaxTime=Business_MaxTime;
this.Business_MinTime=Business_MinTime;
this.default_proporion=Default_Proporion;
}
(4)枚举类型需要尽可能少的定义get方法,保证枚举数据的安全
//get方法已省略
public void setProportion(double proportion) {
this.proportion = proportion;
}
(1)业务办理记录类数据定义
public class Bank_Business_Record implements Comparable<Bank_Business_Record> {
public long arrive_time;//到达时间戳
public long business_time;//业务办理时间戳
public long finish_time;//结束时间戳
public int index;//取票号码
public int bussiness_id;//办理业务id
public String business_name;//办理业务名
public String windows_name;//窗口名
public int windows_ID;//窗口id
public char windows_type;//窗口类型
public int customer_ID;//客户id
public boolean if_VIP;//客户是否为VIP
(2)重写排序方法,按照取号码升序进行Collection.sort排序
@Override
public int compareTo(Bank_Business_Record o) {
if(this.index < o.index){
return -1;
}else if(this.index == o.index){
return 0;
}else{
return 1;
}
}
(3)get、set方法
//方法已省略
(1)客户类数据定义
public class Bank_Customer {
private int Customer_ID;//客户ID
private int Customer_Business_ID;//客户办理的业务ID
private int Customer_Index;//客户排队叫号码,因为时间问题,将客户ID默认为排队叫号码
private long Arrive_Time;//客户到达时间
private long Business_Time;//客户业务办理时间,由Bank_Random类里的方法生成随机时间
private long Finish_Time;//客户完成业务时间
private boolean If_VIP;//客户是否为VIP
(2)方法构造器
//客户构造器
public Bank_Customer(int customer_id,int business_id,int index,long arrive_time,boolean if_VIP) {
Customer_ID=customer_id;
Customer_Business_ID=business_id;
Customer_Index=index;
Arrive_Time=arrive_time;
If_VIP=if_VIP;
}
(3)get、set方法
//方法已省略
(1)窗口类数据定义
private String Windows_Name;//窗口名
private int Windows_ID;//窗口ID
private char Windows_Type;//窗口类型:A、B、C
private ArrayList<Integer> Windows_Business;//窗口支持服务集
private boolean If_WindowsFor_VIP;//窗口是否为VIP专窗(即C类窗口)
private long business_end_time=0l;//窗口业务结束时间(即窗口是否Open,根据时间流动与其进行比较,若达到指定服务时间,打开窗口叫号新客户)
(2)方法构造器
//银行窗口构造函数
public Bank_Windows(String windows_Name,char type,int windows_ID,boolean if_WindowsFor_VIP){
Windows_Name = windows_Name;
Windows_Type = type;
Windows_ID = windows_ID;
Windows_Business = new ArrayList<Integer>();
If_WindowsFor_VIP=if_WindowsFor_VIP;
switch (type) {
case 'A':
for(int i=1;i<9;i++)
Windows_Business.add(i);
break;
case 'B':
Windows_Business.add(1);
Windows_Business.add(2);
Windows_Business.add(4);
Windows_Business.add(5);
Windows_Business.add(7);
break;
case 'C':
for(int i=1;i<9;i++)
Windows_Business.add(i);
break;
default:
break;
}
}

public static int served_VIP = 0;//服务VIP客户计数
(4)创建输出格式
public final static SimpleDateFormat dft = new SimpleDateFormat ("yyyy.MM.dd HH:mm:ss");//时间格式定义
public final static DecimalFormat double2 = new DecimalFormat("######0.00");//输出保留2位小数
(5)创建全局时间(long)参数
public final static long R=600000l;//设置单位时间R=10分钟=60*10*1000l
public static long Open_time = 0l;//时间戳初始化

public static Bank_Windows B2Windows=new Bank_Windows("B2",'B',2,false);
public static Bank_Windows C1Windows=new Bank_Windows("C1",'C',1,true);

public static HashMap<Integer,Integer> business_statistic_map=new HashMap<Integer,Integer>();//记录业务次数
public static HashMap<Integer, Bank_Business_Enum> business_enum_map=new HashMap<Integer, Bank_Business_Enum>();//映射方便查找业务
(8)创建记录客户、业务记录的ArrayList

7. 测试用例
(1)设计方法证明随机分配的有效性与可靠性
(2)Java中的Math.random()是线性均匀的
(3)根据自定义的数据范围对生成数的百分比进行控制
(4)下图证明了方法可以控制随机数生成的比例可以固定在“3:7”,且保持了随机性
(1)VIP队列:根据VIP客户 到达时间进行取号排序。
(2)普通队列:根据普通客户、VIP客户 到达时间进行取号排序。
(1)结束营业时间(客户生成方法在17:00前随机生成,排队造成的业务延期将会延长上班时间,延后结束营业时间)
(2)今日服务人数
(3)VIP与普通客户的占比
(4)各业务办理的占比
(5)累计业务服务时间、各类窗口业务服务时间占比、人均业务服务时间
(5)累计等待时间、各类窗口等待时间占比、人均等待时间
(1)根据VIP占比
(2)根据B窗口不支持业务
(3)根据网银业务占比(网银业务时间占比大)
(4)根据客户平均等待时间
(5)以下是多情况运行截图
(1)总客户列表,无序,按照排到的业务顺序
(2)A类窗口客户列表,有序,按照取号码升序
(3)B类窗口客户列表,有序,按照取号码升序
(4)C类窗口客户列表,有序,按照取号码升序
8. 总结
(1)新接触了Enum类,学习并掌握其使用方法
(2)第一次尝试使用时间流动方法,根据秒来进行操作
(3)使用Math.Random来进行固定比例的生成
(4)尝试了新的方法来加锁与解锁
(1)巩固了时间的计算与调用
(2)多次使用HashMap与ArrayList,并调用方法
(3)类的创建、定义与调用的巩固
(4)结合了OS系统原理内容,分析银行叫号、分配业务、办理的同步与互斥
(1)时间的定义还需完善
(2)互斥的部分调试时间较长
(3)分析窗口不够细,需要完善
(4)打印格式、代码模块比较乱
