Scenarios for a complex systems airport modelling framework
The airport is a prime example of a complex system. Complex systems are characterised by multiple stakeholders, multiple operational objectives and complex interactions and interdependencies between many actors. Some of this inherent complexity can be mitigated by providing a specific modelling perspective and identifying the boundaries of the modelling problem. A systematic and explicit development of the links between users of the model, the high level modelling objectives and modelling capabilities (i.e. modelling requirements) can help to provide such a perspective and identify boundaries. In addition, explicit model usage scenarios and modelling requirements are crucial for the verification and validation of models. Furthermore, such scenarios are a key enabler in the development of reusable modelling tools.
It is found that a systematic approach, such as that based on systems engineering or a Concept of Operations (CONOPS), has not yet been applied to develop modelling scenarios and requirements in the existing airport passenger terminal modelling literature. This paper presents a method based on the CONOPS methodology to structure usage scenarios using modelling objectives, users, operational policies and model capabilities. Using existing airport passenger terminal models as a basis, it is found that there are three major operational objectives for airports, namely: passenger satisfaction, facilitation efficiency and facilitation security. It is shown that a model usage scenario comprises metrics, the links between them and airport, passenger, passenger traffic, flight and service characteristics. A number of case study model usage scenarios are constructed based on different combinations of the above metrics and system characteristics as determined by the modelling objectives. It is proposed that airport passenger terminal models can be classified under high level usage categories of review and analysis, planning and design, and real-time operations.

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
