The Brazilian airport network underwent significant changes from 2000 onwards. There were changes in the structure of ownership, management, and operation, highlighting the process of airport concessions. The network has a flexible structure and is subject to interference from external factors. The importance and centrality of airports varied in th...

The research aims to propose a methodology to estimate the reliability of the Brazilian airport network (domestic passenger traffic), based on the centrality of airports (Network Theory). The applied methodologies are related to Network Theory, a branch of Graph Theory, and reliability. Reliability is associated with the good functioning of a produ...

A administração é uma área multifacetada, composta por diversos pilares que se complementam, proporcionando maior previsibilidade nos resultados a serem alcançados, bem como contribuem para a melhor tomada de decisão, no momento certo. A realidade apresentada ao mundo pela pandemia do Corona Vírus, trouxe desafios e contingências que, seriam possív...

This study uses a MCDA tool to analyse and improve Spanish airports performance and efficiency. Thus, a holistic study using MACBETH (with PESA-AGB) is used. This study has never been applied before in Spanish airports. Firstly, a literature review related to this study keywords is conducted, as well as about benchmarking concept applied specifical...

Purpose: This research aims to address an issue that today is a significant challenge for all signatory countries of the International Civil Aviation Organization (ICAO). The implementation of the areas for improving practices recommended in the Global Navigation Plan (GANP). More specifically on the theme of Airport Collaborative Decision Making (...

Airport benchmarking depends on airport performance and efficiency indicators, and it is an important issue for business, operational management, regulatory agencies, airlines and passengers. Using the MACBETH (Measuring Attractiveness by a Categorical Based Evaluation Technique) approach, a hierarchical additive value model is constructed with cri...

Due to the deregulation of the airline market in Europe, LCC’s have shown a fast growth in the last decade. This change in airline market has affected the way many airports operate and it’s expected that this impacts not only in airport performance, but also in its hinterland. Tourism development is one of the main beneficiaries of this new paradig...

Due to airline market deregulation in Europe LCC’s (Low-Cost Carriers) depicts a fast growth in the last decade and it’s expected that this growth continues in the next years. Also, this European airline market change has affected the way many airports operate and it’s likely that this change impacts not only airports performance and efficiency, bu...

This document is designed to help airports around the world in their performance management efforts by providing a useful set of performance measures across some categories. The measures are divided into seven groups, referred to as Key Performance Areas (KPAs), and the 57 individual measures are applied to as performance Indicators (PIs). For each...

The air transport has suffered a remarkable transformation over the past decade. The way we travel today is quite different from how we did ten years ago. Due to the rise of low cost carriers, the market of air transportation has been constantly changing and presently witnessing the transformation of legacy carriers in order to manage to continue o...

The growth of the low-cost carriers (LCC’s) change how airports are manage and their performance. This study focus on the literature review of the low-cost carriers growth, airport performance, multiple-criteria decision analysis (MCDA) and future work. In this study we model the airport key performance areas and key performance indicators in a mu...

The utility of the airport benchmarking process is widely recognized in a world where competition among airports is becoming more than ever a reality. Therefore there is a need for a wide consensus to establish and construct reliable databases for measuring airport performance and consequently to evaluate the development and the implementation of e...

The general aim of this work is the development of airports performance and efficiency predictive models using robust but flexible methodologies, and incorporating traditional indicators as well as new constraints. Particularly it shows and compares the efficiency evolution of the same airport along several years, under several constraints, based o...

Air transport underwent profound changes in recent decades. Some airport facilities were privatized although others remained under public control, all pursuing commercial purposes through specialization/diversification of its business models, which proved to be quite profitable for infrastructures above a certain traffic threshold. For smaller ones...

Given the relevance of tourism to the Portuguese regional economies, the main aim of this paper is to study whether the investments made in related-tourism facilities contributed to the regional growth of all the Portuguese regions included in the NUTS II Norte and Alentejo, with special emphasis on the NUTS III Alto-Trás-os-Montes and Alentejo Cen...

There are several studies to benchmark airports through Passenger, Cargo and Movements, which are the most common and used key performance indicators. But in general these studies don't allow establishing relationships between the ranking position of a certain airport and the value generated associated with that particular position, either within t...

Airport operators, planners and regulatory agencies to measure the economic contribution of an airport to its local and regional surroundings, frequently use economic impact studies. The most common methods to measure airport economic impacts have been the Input-Output method, the Collection of Benefits method and most recently the Catalytic method...

This work relates to airports benchmarking which is a very important issue for stakeholders. Airports benchmarking depends on airport performance indicators which are also important issues for business and operational management, regulatory bodies, airlines and passengers. There are several sets of indicators to evaluate airports performance and al...

The present paper proposes an optimization algorithm for dealing with optimal control issues based on direct methods. Since direct methods involve the discretization of the differential equations modelling the dynamics of the system and the cost function, the dimension of the resulting problem may be very high, which can be a challenge for most opt...

The paper proposes a framework for global optimization in the context of optimal control. The approach is based on successive local optimizations stemming from optimally chosen re-start points. The optimization method which is dealt with for that matter is the Dynamic Canonical Descent algorithm which was proven to have better performances over mos...
