Complete the task on AnyLogic

Offering additional earnings for the programmer. You need to complete the task on AnyLogic. The computer is connected to four terminals from which the solution of tasks is carried out. On command from the terminal, editing, broadcasting, planning and decision operations are performed. Moreover, if at least one terminal performs planning, the rest are forced to stand idle due to a lack of RAM. If two terminals issue a decision requirement, the remaining two are idle, and if three terminals are running, the remaining terminal is locked. The intensity of the different types of tasks is equal. Tasks of one type from one terminal come in exponentially distributed time intervals with an average value of 160 s. The performance of any operation lasts 10 seconds.
Simulate the work of the computer for 4 hours. Determine the processor load, terminal downtime probability and the frequency of simultaneous broadcasting from three terminals.
