A New Approach for Disruption Management in Airline Operations Control

Most of the research efforts dealing with airline scheduling have been done on off-line plan optimization. However, nowadays, with the increasingly complex and huge traffic at airports, the real challenge is how to react to unexpected events that may cause plan-disruptions, leading to flight delays. Moreover these disruptive events usually affect at least three different dimensions of the situation: the aircraf...

Development of a flexible language for mission description for multi-robot miss...

AbstractThe work described in this paper is part of the development of a framework to support the joint execution of cooperative missions by a group of robotic vehicles, in a simulated, augmented or real environment. Such framework brings forward the need for formal languages in which to specify the group of vehicles that compose a team; the scenario in which they will operate; and the definition of the mission...

De dentro de fora e de fora de dentro: representações sociais da prostituição f...

A fim de analisarmos as representações sociais da prostituição e a percepção de preconceito e estigmatização por parte das prostitutas, realizamos dois estudos em Aracaju no nordeste do Brasil. A pesquisa foi realizada em Janeiro de 2008, os dois estudos utilizaram entrevistas estruturadas. O primeiro deles foi realizado com 66 moradores de diversos bairros desta cidade o segundo estudo envolveu nove prostituta...

The Impact of Benevolence in Computational Trust

Intergroup time bias and racialized social relations

Within the framework of intergroup relations, the authors analyzed the time people spent evaluating ingroup and outgroup members. They hypothesized that White participants take longer to evaluate White targets than Black targets. In four experiments, White participants were slower to form impressions of White than of Black people; that is, they showed an intergroup time bias (ITB). In Study 1 (N = 60), the ITB ...

Trust and Normative Control in Multi-Agent Systems

Towards an Autonomous and Intelligent Airline Operations Control

Studies have estimated that irregular operations (flights affected by a disruption) can cost between 2% and 3% of the airline annual revenue and that a better recovery process could result in cost reductions of at least 20%. Even for small airlines this can represent millions of Euros. In this paper we propose a multi-agent system (MAS) whose members represent the roles, functionalities and competences xisting ...

Trust and Normative Control in Multi-Agent Systems: An Empirical Study

ANTE: Agreement Negotiation in Normative and Trust-Enabled Environments

Research on negotiation and task allocation has been in the multi-agent systems realm since its inception as a research field. More recently, social aspects of agenthood have received increasing attention, namely developing on the fields of normative and trust systems. The integration of these different research contributions will allow to build robust applications for electronic agreement negotiation, aiming ...

Airline Operations Control: A New Concept for Operations Recovery

The Airline Operations Control Centre (AOCC) of an Airline Company is the organization responsible for monitoring and solving operational problems. It includes teams of human experts specialized in solving problems related with aircraft, crew members and passengers, in a process called disruption management of operations recovery. In this chapter we propose a new concept fro disruption management in this domain...
