At bob International Airport, departing passengers are directed to international departures or bago departures. For both categories of departing passengers, there are experienced passengers and inexperienced passengers. The experienced passengers typically do not require much interaction with check-in agents, as they are comfortable using online check-in systems or the automated kiosk systems. The inexperienced passengers typically interact with the check-in agents. Research shows that the experienced bago departing passengers check-in online and do not interact with the agents, and neither do they use the kiosk systems. However, the inexperienced bago passengers use the kiosk systems, typically spending 4 minutes to complete check-in. The inexperienced bago passengers do not interact with the check-in agents. Research also shows that the experienced international departing passengers must visit with the check-in agents to verify their travelling documents. Typically, each of these passengers spend 6 minutes with the check-in agent, and do not utilize the online check-in or automated kiosk systems. Lastly, the inexperienced international departing passengers interact with the check-in agents to verify their travelling documents and to get answers to any questions regarding their flights. These interactions last 10 minutes with the check-in agents. There is no need for these passengers to use the online check-in or the automated kiosk systems. Once passengers have checked in, they must go through security clearance, which takes 1 minute. Security clearance is required for all categories of passengers. Table 1 shows the average hourly arrival rates for the different categories of passengers, Bago Passenger Experienced - 108 Per Hour Bago Passenger Inexperienced - 80 International Experienced - 90 International Inexperienced - 50 for the afternoon period: 1pm - 6pm. Current resource allocation is as follows: Eight security officers Five check-in agents Four kiosk systems The security officers and check-in agents must remain at their workstations until the last passenger who comes to Piarco Airport in the afternoon period (1pm - 6pm) completes check-in and security clearance. Discuss the implications of the waiting lines relating to the security clearance area, using the following information: CVa = 1 CVp = 1.25 Waiting costs = $1 per minute per waiting customer Hourly rate for the security guards = $15
