本程序是操作系统里面常用的一个程序，某工厂有两个生产车间和一个装配车间，两个生产车间分别生产A、B两种零件，装配车间的任务是把A、B两种零件组装成产品。两个生产车间每生产一个零件后都要分别把它们送到装配车间的货架F1、F2上，F1存放零件A，F2存放零件B，F1和F2的容量均为可以存放10个零件。装配工人每次从货架上取一个A零件和一个B零件然后组装成产品。用多线程并发进行正确的管理。-This procedure is commonly used operating system inside a process, a factory has two production workshop and an assembly shop, the two production workshop in the production A, B in two parts, the assembly shop of the task is to A, B assembled into two parts products. Each of the two production workshop production after a parts, respectively, have them sent to the assembly shop shelves F1, F2 on, F1 stored parts A, F2 parts store B, F1 and F2 are the capacity of 10 parts can be stored. Assembly workers each from the shelves for a Part A and a B part and then assembled into products. Used to correct multi-threaded concurrency management.
