Abstract: The sleeping barber model problem in computer science is a classic inter-process communication and synchro- nization problem between multiple operating system processes, however, most researchers was used to introduce extra functions to extend the original model, ignoring new complicated problems arose from semantic changes and not giving innovative solutions. Based on life prototype and semantics of new model, this paper redefined the barber model with complicated semantics,and proposed analysis pattern of resource oriented and provided solutions and algorithms of in- ter-process synchronization problems within complicated semantics based on Try-p semaphore and p-v primitives.
