The processing times where observed at three airports and it was felt necessary to
analyze if the data at all three airports has significant variations in the data due to the
change in the group size or number of bags per passenger.
Thus, statistical analysis was carried out to confirm the same. The single factor Analysis
of Variance was performed for all the check-in modes. The results of the test are
shown in Table 1, Table 2 and Table 3. It was concluded that there is no significant
variations in the data collected at three airports and all the samples can be pooled
together.

Annexure B - Simulation Model: Description and Users Guide

INTRODUCTION
The Simulation model is designed in MS Office Excel 2007. The simulation model
simulates the check-in process at airport with self-service and web check-in. It is
designed to estimate the requirements for a two step self service check-in, which
includes kiosks and bag drop-off at the airport. The model enables the users to
analyze the impacts of the changes made in resources and estimate the requirements
of check-in counters, kiosks and bag drop-off. The structure of the model, the inputs
required and interpretation of results have been explained to enable the user to get
the maximum utility from the model.
The model has been kept as simple as possible and there is no additional software or
macros required to run the simulation. The model is limited to the size of the inputs.
The model can only compute for maximum 2500 Peak hour passengers or maximumresources of 25 in each mode.
1. Structure of Model
The model is designed in Excel2007. To use the model and give inputs, it is first
necessary to understand the structure of the model. The data is arranged in number of

2. Inputs in the Model
To run the model it is necessary to give correct inputs. Each input parameter is
discussed and the key characteristics and limitations are discussed in this section to
enable the user to give correct inputs. The input sheet is as shown in the Figure 2.

2.3. Check-in Open Times
This is the opening time for the all the counters, kiosks and bag drop-off. The time has
to be given in minutes. It is necessary to decide the check-in open times as that will
govern the number of passengers arriving at the airport. This input cannot be Zero.
2.4. Check-in Close Times before STD
It is time in minutes for closing of check-in counters before departure time of the
flight. If assumed zero, the model considers the full duration between check-in opentimes and departure.
2.5. Passengers by each Check-in Mode
This is expected breakup of the passengers using each mode to check-in in
percentages. The user needs to provide the information such that the expected break
up totals 100%. The numbers for each mode is calculated by the model and shown in
the next cell to it, which cannot be modified by the user. If any of the modes are not
available at the airport the user can input zero for the mode, but the total of all three
cells should be 100. The user can modify these proportions to analyze the impacts on
the available resources.

times and is to be given by user and thus has been converted to percentages. So the
user has to first convert the total time in percentage and passengers arriving at each
10% time interval should be calculated and used as input in one of the three columns

The table also summarizes the Maximum Wait Time and Average Wait Time for each
mode. The average Total process times is also indicated in the last column. The total
process time includes the waiting time and processing time.
3.2. Server Usage
This sheet shows how many passengers were processed by each server in proportion
and in numbers. The table enables the user to understand usage of server. The user
can compare the performance of each server and decide if he/she wants to reduce one
server which is underutilized.
