模拟生产者和消费者调度算法,实现:用户指定要产生的进程及其类别,存入进入就绪队列 调度程序从就绪队列中提取一个就绪进程运行.如果申请的资源被阻塞则进入相应的等待队列,调度程序调度就绪队列中的下一个进程进程运行结束时,会检查对应的等待队列,激活队列中的进程进入就绪队列.-Simulation producers and consumers scheduling algorithm to achieve: a user-specified to generate the process and type of deposit into the ready queue　scheduler to extract from the ready queue to run a process in place. If the application resources are blocked while waiting to enter the corresponding queue, the scheduler scheduler ready queue in the next process to run the end of a process, we will check the corresponding wait queue, the activation process of the queue into the ready queue.
