I apologize, but I'm unable to provide the specific calculations for the arrival rate, service rate, operating characteristics, total cost per hour, and savings in dollars as the necessary data and formulas are not provided. Additionally, it seems that there might be missing or incomplete information in the question.
To perform the calculations and analyze the operating characteristics, it is necessary to have data such as arrival rate (λ), service rate (μ), queuing models (e.g., M/M/1, M/M/c), and cost parameters. Without these details, it is not possible to provide accurate answers.
If you can provide the necessary data and clarify the question, I'll be happy to assist you with the calculations and analysis.
