Modeling the large scale disruptions of an airline network
Milan Janić, 2005, izvirni znanstveni članek

Opis: When the large-scale disruptions of airline networks occur, they can cause significant deterioration of the planned schedule. Such deterioration shows upin the form of long delays, rerouting and/or cancellation of flights. This paper presents a model for assessment of the economic consequences of large-scale disruptions of an airline single hub-and-spoke network. These consequences are expressed by the cost of delayed and cancelled complexes of flights. The model is based on the theory of queuing systems with the airline hub airport as a server and the complexes of flights as customers. The difference between the service time of the affected and planned complexes determine their delays caused by a given disruptive event. The cost of delays and revenues of the affected flights, and global airline mitigating strategies are used to determine the total airline cost of delayed and cancelled complexes. The model is applied to the disrupted hub-and-spoke network of a large European airline. The purpose is to illustrate the model's planning nature, complexity of the problem, influence of the relevant factors,and the magnitude of the economic consequences.

Liberalisation of European aviation : analysis and modelling of the airline behaviour
Milan Janić, 1997, izvirni znanstveni članek

Opis: This paper deals with the analysis and modelling of behaviour of the Western European airlines during the first phase of the gradual liberalisation of the EU (European Union) aviation market. The framework for monitoring this behaviour and appropriate methodology for registering significant changes in the airline industry, specific airlines, and the aviation market itself has been developed. Three classes of empirical models have been estimated: airline growth and financial performances, airline mergings and alliances by holding of equity stakes in partners, and airline relationships (cooperation and/or competition) on the EU air route network consisting of five sub-models. The EU airline sub-models are: market share, market concentration, air travel demand, quality of services, and pricing policy. The least-square regression technique has been applied over the cross-sectional data for making the empirical estimates.

An application of the methodology for assessment of the sustainability of the air transport system
Milan Janić, 2004, izvirni znanstveni članek

Opis: An assessment and operationalization of the concept of a sustainable air transport system is recognised as an important but complex research, operational and policy task. This paper represents an academic effort to properly address the problem of assessing the sustainability of an air transport system. In particular, the paper presents a methodology for assessment of the sustainability of an air transport system. This methodology is based on an indicator system related to particular dimensions of the air transport system's performance considered from the aspects of particular actors involved. Specific cases are selected to illustrate the application of the proposed methodology.
