Abstract:

The task of optimizing the optimal quantity of technological resources of a hub airport’s functional subsystem, executing an individual process step of ground handling, is considered. This problem is relevant to hub airports. The analysis is limited to limited availability systems in which handling of certain orders can be performed only by certain resources which are used in reference to automated and mechanical equipment, industrial equipment, personnel, etc. The optimization problem is formulated in a probabilistic statement. An approach to solving the problem is described. We suggest using

Abstract:

The layout design of an airfield area plays a crucial role in ensuring the efficiency of aircraft ground operations. In order to minimize delays caused by insufficient capacity and prevent resource wastage due to excessive capacity during the operational phase, this paper developed a prediction model for operational efficiency leveraging queuing network theory and machine-learning models. Our approach involves four key steps: (1) establish a theoretical framework for analyzing the operational efficiency of airfield area layouts based on queuing network theory, (2) employ a combination of discr

Abstract:

Determining the resource requirements at airports especially in-ground services companies is essential to successful planning in the future, which is represented in the resources demand curve according to the future flight schedule, through which staff schedules are created at the airport to cover the workload with ensuring the highest possible quality service provided. Given in the presence of variety service level agreements used on flight service vary according to many flight features, the resources assumption method makes planning difficult. For instance, flight position is not included in

Automated airports equipped with UAVs are expected to become important equipment for improving quality and reducing costs in many inspection scenarios. This paper focuses on the automated inspection business of UAVs dispatched by automated airports in highway scenarios. On the basis of considering the shape of highway curves, inspection targets, and the energy consumption characteristics of UAVs, planning the flight parameters of UAVs is of great significance for ensuring the ef

The Small Aircraft Transportation System (SATS) is an improved mode of air travel for personal transportation that makes use of the network of commercial and general aviation airports. It is a system of highly developed aircraft and ground facilities that can safely and affordably move people among several thousand of currently underused airports throughout urban, suburban, and rural America. The SATS is a combined program that consists of three main components: new vehicle technology, airspace infrastructure, and SATS service provider.

In order to handle this increase in demand, airports need to physically expand or the management of the airports needs to improve. When the demand at OR Tambo International Airport gets too high, more passengers will need to travel to Lanseria International Airport, which will therefore need to be expanded.

The aviation industry has always faced uncertainties and vulnerabilities from all aspects, making planning and optimising its components quite challenging.

This model is then used to propose a set of metamodels that link the KPIs of the system to the input parameters through some mathematical equation
