According to the characteristics of airport pavement traffic, we discuss a method of building an airport pavement traffic model which is based on CPN theory and simulate a practical situation as well. The method overcomes the shortage of modelling with normal Petri Net theory, solves the difficult problems of airport pavement traffic such as complex traffic nets, frequent road changing, etc., r...

Building simple and accurate models of hub airports can considerably help one understand airport dynamics, and may provide quantitative estimates of operational airport improvements. In this paper, three models are proposed to capture the dynamics of busy hub airport operations. Two simple queuing models are introduced to capture the taxi-out and taxi-in processes. An integer programming model ...

According to the current Airport planning and design practices, for a given demand level there is a corresponding space requirement. While in practice, there are always trade-offs between cost and levels of service, labor and automation, equipment and fixed facilities, and expansion of existing facilities and the addition of new ones. In this research, the airport passenger Terminal Building (P...

Lester B. Pearson – Toronto International Airport is undertaking a $4.4B development program comprising a new 390,000 sq. m. terminal building (replacing two aging terminals), three new runways, cargo facilities, a central utilities plant, and an expanded road system and parking facilities. This activity is proceeding while the airport continues to operate and while requirements evolve in respo...

The airline industry has been changed significantly after the September 11 of 2001, while delay and congestion at airport have been consistently a problem to passengers, airlines and airports since the last decade of the 20 century. Most of previous methods to reduce airport delay and congestion mainly focus on airport capacity expansion through building new runways, which incurs billions of do...

An entire airport terminal building is simulated to examine passenger flows, especially international departures. First, times needed for passengers to be processed in the terminal building are examined. It is found that the waiting time for check-in accounts for more than 80 percent of the total waiting time of passengers spent in the airport. A specialpurpose data-generator is designed and de...

Airports are an ideal application area for simulation. The processes are in a continuous state of change, are complex and stochastic, involve many moving objects, and require a good performance that can be measured in several different performance indicators. Within airports, but also between airports, the same kind of questions are answered over and over again. Often, however, new simulation m...

The study aimed at assessment of noise levels in Alexandria airport and measurement of hearing acuity--among other health parameters of the working personnel. By performing 65 sound pressure level measurements, a questionnaire and air conduction audiometry, significant hearing defects could be revealed. Deficiencies affected hearing levels at all frequencies but especially higher frequencies in...
