Question:
Etihad airline flight travels from Abu Dhabi airport (AD) to London Heathrow (LHR) on weekly basis. The airline representative informs that there are three types of travelers who travel from Terminal 3 of the AD:
• Experienced travelers: These passengers check in online and do not speak with any agent nor do they take any time at the kiosks.
• Occasional travelers: These passengers spend 3 minutes with an agent. Inexperienced travelers: These passengers need to talk 5 minutes with an agent and spend 5 minutes at the kiosks.
After a passenger checks in online, or talks with an agent, or uses a kiosk, the passenger must pass through security, where they need 1 minute independent of their type. From historical data, the airport is able to estimate the arrival rates of the different customer types at Terminal 3 of AD airport: Experienced travelers: 100 per hour
• Occasional travelers: 60 per hour Inexperienced travelers: 50 per hour
At this terminal, there are five security check stations, six agents, and two electronic kiosks. Passengers arrive uniformly from 6 a.m. to 10 a.m., with the entire system empty prior to 6 am, and no customers arrive after 10 a.m. All workers must stay on duty until the last passenger is entirely through the system (e.g., has passed through security). What are the levels of impliedUutilization at each resource? .
