A hot news station has 10 automatic machines. Each machine can process an average of 4 messages per hour. At the working station in the mode of the Eclang system, the stream of messages to be processed is a stationary Poisson stream with an average rate of 30 messages per hour. Please determine the criteria to evaluate the quality of the station's message processing. Please determine: - What kind of system is the above system? Draw the state diagram of the system. - Calculate the performance evaluation criteria of the station: P., Pc, Pp,,,,,,,H. - In order for the message rate to be processed at not less than 99%, at least how many message processors should be arranged?
