Level of service at the airport check-in area is important not only to passengers but also to the airport operators and airlines. This book explains a computational method to design or redesign check-in halls using concepts about level of service, passenger arrival fluctuations, furniture layout, queue arrangement, number of counters and optimization techniques. The concept proposed in this book may be applicable to other types of transport interchanges as well. This book offers a range of topics including: ? A technique to generate the pattern of departure passengers. ? Spreadsheet methods to deal with passenger arrival variations during a 24 hour period. ? Two simulation models with different level of resolution. ? Number of different layout arrangements. ? Cost of furniture and personal.
