The check-in scenario starts with the arrival of passengers to the terminal. Inter- arrival times of passengers are classified as random with minimum equal to 1, maximum equal to 2 and most likely equal to 1.5 minutes.
Passengers have already booked to travel via LIV1 airline.
The LIV1 airline has dedicated 2 check-in counters. 1 staff member is allocated at each counter to provide the required check-in service. In average, both staff members take between 5 min (min), and 15 min (max) per passenger. This airline prefers to arrange passengers into two separate queue lines for each check-in desk. The shortest queue selection criterion is preferred by passengers.
After checking-in a passenger, a detection equipment in the security area applied on both airline passengers, as this is the only security screening available at this airport. Only one screen officer is allocated to monitor the screening operation.
The screening last for a couple of minutes to 3 min with an average of 2.5 minutes per passenger. When necessary, 10% of passengers will be asked by the screen officer to walk once more (could be more) through the detection equipment and this may increase the service time.
Once passengers have passed through the security operations, they arrive in the departure area when they head directly for boarding.
In the above check-in problem, both passenger travelling times and luggage have not been considered.
The Coursework Tasks
For this piece of individual coursework, you are required to apply simulation modelling to deliver the tasks below:
Task 1- After reading the scenario above, provide problem brief, main aim, objectives, tools and techniques, and key performance indicators.
Task 2- Use tabular form to define and analyse the Airline Check-In Problem. This analysis includes decomposing the system being investigated into its main components including entities, attributes, activities, state variables, and events.
Task 3- An appropriate flowchart with detailed explanations.
Task 4- Develop a simulation model for 200 passengers to imitate the above Airline Check- In Problem (“As-Is” situation). Five simulation runs are required, at least one experiment (scenario) to redudce:
Overall boarding time.
Average waiting time of passengers.
A comparison via Excel diagrams of the “As-Is” scenario with any other improvement scenarios “What-If” is required.
Task 5- Conclusion and Recommendations for further improvement (bullet points)
