Consider an car wash where customers arrive in exponential fashion with an average rate of 20 per hour. On arrival, the customers wait for the one machine car wash. The average machine cleaning time follows an exponential distribution with an average of 3 minutes. After the car is clean, the car wash provides a complimentary hand dry utilizing one employee. The hand dry time follows an exponential distribution with an average of 2 minutes. Simulate this system for 8 hours to analyze the performance of this system. First, provide the results of the system above. Second, as the owner, change the system to optimize and explain the justification for your simulated changes. 50% of the homework grade will be based on correctly articulating in very simple terms the takeaways. This should be accomplished in 1 or 2 paragraphs for each situation.
