    The Complex ATM Position Paper is the common research vehicle that defines the high-level, strategic scientific vision for the ComplexWorld Network. The purpose of this document is to provide an orderly and consistent scientific framework for the WP-E complexity theme. The specific objectives of the position paper are to: - analyse the state of the art within the different research areas relevant to the network, identifying the major accomplishments and providing a comprehensive set of references, including the main publications and research projects; - include a complete list of , a list of application topics, and an analysis of which techniques are best suited to each one of those applications; - identify and perform an in-depth analysis of the most promising research avenues and the major research challenges lying at the junction of ATM and complex systems domains, with particular attention to their impact and potential benefits for the ATM community; - identify areas of common interest and synergies with other SESAR activities, with special attention to the research topics covered by other WP-E networks. An additional goal for future versions of this position paper is to develop an indicative roadmap on how these research challenges should be accomplished, providing a guide on how to leverage on different aspects of the complexity research in Air Transport

    Characterising and modeling the co-evolution of transportation networks and territories

    Full text link
    The identification of structuring effects of transportation infrastructure on territorial dynamics remains an open research problem. This issue is one of the aspects of approaches on complexity of territorial dynamics, within which territories and networks would be co-evolving. The aim of this thesis is to challenge this view on interactions between networks and territories, both at the conceptual and empirical level, by integrating them in simulation models of territorial systems.Comment: Doctoral dissertation (2017), Universit\'e Paris 7 Denis Diderot.

    Metropolitan Research: Methods and Approaches

    Get PDF
    Metropolitan research requires multidisciplinary perspectives in order to do justice to the complexities of metropolitan regions. This volume provides a scholarly and accessible overview of key methods and approaches in metropolitan research from a uniquely broad range of disciplines including architectural history, art history, heritage conservation, literary and cultural studies, spatial planning and planning theory, geoinformatics, urban sociology, economic geography, operations research, technology studies, transport planning, aquatic ecosystems research and urban epidemiology. It is this scope of disciplinary - and increasingly also interdisciplinary - approaches that allows metropolitan research to address recent societal challenges of urban life, such as mobility, health, diversity or sustainability

    Bayesian participatory-based decision analysis : an evolutionary, adaptive formalism for integrated analysis of complex challenges to social-ecological system sustainability

    Get PDF
    Includes bibliographical references (pages. 379-400).This dissertation responds to the need for integration between researchers and decision-makers who are dealing with complex social-ecological system sustainability and decision-making challenges. To this end, we propose a new approach, called Bayesian Participatory-based Decision Analysis (BPDA), which makes use of graphical causal maps and Bayesian networks to facilitate integration at the appropriate scales and levels of descriptions. The BPDA approach is not a predictive approach, but rather, caters for a wide range of future scenarios in anticipation of the need to adapt to unforeseeable changes as they occur. We argue that the graphical causal models and Bayesian networks constitute an evolutionary, adaptive formalism for integrating research and decision-making for sustainable development. The approach was implemented in a number of different interdisciplinary case studies that were concerned with social-ecological system scale challenges and problems, culminating in a study where the approach was implemented with decision-makers in Government. This dissertation introduces the BPDA approach, and shows how the approach helps identify critical cross-scale and cross-sector linkages and sensitivities, and addresses critical requirements for understanding system resilience and adaptive capacity

    Planning for post-industrial society : a theoretical framework

    Get PDF
    Bibliography: leaf 395-409.This research stems from the proposition that important qualitative changes are occurring within Western Society, and that these changes call for new forms of individual and organisational adaptation. Planning is a pre-eminently suitable way of adapting in an appropriate fashion to the complexities of change, rather than through ad hoc responses. Four tendencies appear to be prevalent and to persist within what may be termed these technologically advanced societies; these are: high and accelerating rates of technological and social change; an unevenness in these rates of change, especially among different parts of the environment in which organisations operate; an increasing interconnectedness and interdependence among these environmental parts; and an increasing overall size and complexity of the environment and its consistuent organisations. System's theory, it is felt, will provide a particularly apt conceptual framework for the consideration of these problems, which will be made explicit and amplified primarily through an exploration of these concepts which are central to a theory of behavioural systems. It is argued that the conditions in which social activity occurs are, in many parts of the world, becoming subject to important qualitative changes which demand new responses and modes of adaptation of behaviour, which look to what may be termed a new 'appreciative' outlook, in which a central element will be a recognition that units within ecological consideration must become the basis for achieving equitable outcomes. Chapters 7 and 8 discuss planning, the method which all social units at all levels use when attempting to regulate relations with others in order to continue functioning effectively. Here, the conceptual framework will be used to examine this problem of planning. Further, to refine the notion of planning, technical, natural, institutional, economic, conflict and social systems will be examined. In particular, urban planning will be looked at as of increasingly critical concern as the result of the world urbanisation process. A new paradigm for planning will be suggested which draws together the main elements of the thesis, in which the aims and techniques of enquiry will be from the making of explanations which derive from single purpose approaches to the furtherance of understanding desired from a more inclusive and comprehensive standpoint
