AIRLINE CHECK-IN PROBLEM
The Scenario Description
- Airline check-in options and procedures may vary among airlines globally. Some of the check-in procedures could be less efficient than others, especially when the time between departing flights is reduced. In general, any delays eventually affect departures, passengers’ waiting time and service
- In this scenario, LIV1 airline operates in a local airport. This airline has its own regulations to run and manage its check-in area. This includes the way that passengers wait in terms of queue layout, resources used at each check-in counter etc. See Figure 1 for the schematic diagram of the check-in
Figure 1: Schematic diagram of the check-in problem
- 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
- Passengers have already booked to travel via LIV1
- 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
- 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 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
- Once passengers have passed through the security operations, they arrive in the departure area when they head directly for
- In the above check-in problem, both passenger travelling times and luggage have not been
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:
i. Overall boarding time.
ii. 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)
o analysis table, flowchart diagram, both ‘As-Is’ & ‘What-If’ simulation models/ snapshots & other relevant comparison diagrams (outlines are provided above).
o A copy of the developed “As-Is” simulation model (.s8 extension)
o A copy of each of the developed “What-If” scenario (.s8 extension)
o A copy of Excel file including all scenarios allocated in multiple sheet tables (‘As-Is’ & ‘What-If’) and their experiments outputs, analysis plus overall comparison diagrams.
ü Report Word limitation: Not less than 1500 words as an individual report (for the body of the report, excluding Bibliography, References, and Appendices
|– Assessment Criteria
The following criteria will be interpreted appropriately according to the nature of the assessment and the general framework set by the module aim and learning outcomes.
For a Bare Pass Mark (35%)
· Work lacks any academic merit as adjudged by the foregoing.
For an Excellent Mark (>69%)
· Show a thorough understanding of the purpose of the activity.
· Display knowledge of all the relevant principles, theories, and practices and an ability to apply them effectively.
· Provide evidence of extensive reading beyond that listed, including academic journals.
· Demonstrate an ability to select critical points, evaluate them and communicate the conclusions effectively.
· Develop and run models that reflect as realistically and sensibly as possible given situations.
· Develop and run models that are based on sensible and useful options that go beyond given situations.
· Provide analysis, discussion, and comment critically on the results produced by models.
· Provide solutions to business problems that are creative and practicable.
· Provide sound, supported, discussions of further research that may be needed.
