Research of barber model in process concurrency control

In complex process concurrency control, most researchers mainly come up with solutions to some detail problems, as well as the barber model problem. Through analysis and research of barber problems, this paper divides them into three kinds of models, including simple model, standard model and enhanced version. It proposed solutions respectively by indicating the key points of barber problems, such as special case of producer and consumer problems, try-p mechanism and synchronization of processes. Furthermore, there exist some kinds of rules to reference based on p-v primitives and semaphore mechanisms, especially for those complex concurrency processes.
