银行调度系统

银行业务调度系统模拟银行调度系统逻辑。需求 1.银行内有6个业务窗口，1-4为普通窗口，5为快速窗口，6为VIP窗口。2.有三种类型客户：VIP客户，快速客户（交水电费类业务），普通客户。3.一部随机生成各种类型的客户，概率比例为：VIP客户：快速客户：普通客户 = 1：3：6.4.客户办理用时设定最少时间。5.各类型客户在其对应窗口按照顺序办理业务。6.VIP和快速窗口无办理业务时刻受理普通客户，若有应该优先处理对应客户。 面向对象分析与设计1.有三种类型的客户：VIP，快速，普通，异步随机生成个类型客户。a.有一个取号机对象产生号码，好比产生客户。b.三类客户号码编排独立，系统产生一个管理三个号码管理器的对象，号码管理器在系统中只有一个，设计成单例。2。个类型客户在对应窗口按顺序依次办理业务，即依次叫号。a.各个窗口如何获得叫号信息，他一定试问相应的号码管理器。 编程代码实现：
