  • Multiformalism techniques for critical infrastructure modelling

    This paper proposes an approach to use multiformalism techniques for critical infrastructure modelling. To this aim, the state of the art of related works on the subject is surveyed and a general scheme for intra and inter infrastructure models is described. Multiformalism approaches allow modellers to adapt the choice of formal languages to the nature, complexity and abstraction layer of the ...

  • Framing a new approach to critical infrastructure modelling and extreme events

    This paper proposes a new framework to evaluate and improve the resiliency of communities as they face the risk of multiple hazards and cascading infrastructure failure. The central idea is to extend engineering-based fragility models of the effect of extreme events on physical infrastructure and to combine them with regional, economic and social impact models. The modelling framework would ...

  • Reduction techniques in modelling critical infrastructures under the infrastructure interdependencies simulator framework

    Modern, urban population centres are comprised of highly interdependent networks of infrastructures. In normal operating conditions, these interdependencies can be neglected without much trouble, however, in times of emergency, these same interdependencies, often hidden, can debilitate relief efforts. The effects are often noted in disaster response post–mortems as poor distribution of resources ...

  • Infrastructure interdependencies simulation through matrix partitioning technique

    In recent years, there has been considerable interest in modelling and simulating interdependencies among critical infrastructures. For most cases, agent-based frameworks are employed for these types of simulation. In this paper, we present a new approach for interdependencies simulation that we have used in the infrastructures interdependencies simulator (I2Sim). I2Sim implementation is based on ...

  • Aware online interdependency modelling via evidence theory

    Critical infrastructure interdependency models are typically used in a simulation–based perspective, in order to perform 'what if?' analyses and identify structural vulnerabilities in a dynamic perspective. While in the literature some attempts have been made to use interdependency models at real time, such approaches are flawed by the inability to properly determine the ongoing situation. ...

  • Business incubators as economic development tools: rethinking models based on the Korea experience

    The growth rate of Korean business incubators (BI) is explosive compared to growth rate of incubation programs in the United States of America. The authors' secondary and primary research reveals that the stresses of rapid growth exposed difficulties with existing models. These difficulties can be better addressed by working models that extend existing, descriptive frameworks and models. It is ...

  • A hybrid systems model to simulate cyber interdependencies between critical infrastructures

    Critical infrastructures (CI) depend on communications and information technology infrastructure (CITI) for many of their key functionalities, which is known as cyber interdependency. In this paper, we presented a cyber interdependency simulation technique that is based on the idea that overall performance of a CI network is determined by the behaviour of its components at multiple time scales. ...

  • Modelling critical infrastructure via a mixed holistic reductionistic approach

    Infrastructure systems and their interaction mechanisms can be interpreted following a multitude of different approaches, depending on different perspectives and levels of abstraction. In this paper, we propose a mixed approach, in which different representations of the same infrastructure is used in order to define the interdependencies and interactions among infrastructures and their elements. ...

  • A disaster response management system based on the control systems technology

    A networked Critical Infrastructure (CI) system performs functions critical to national economy and security. It is a complex system in the sense of a social-technical system with time-varying boundary and topology, and there are dynamic, uncertain and stochastic factors throughout a whole disaster management process. In this paper, we first present a study aimed at developing a general ...

  • Transition of energy infrastructures: modelling the Brazilian case

    Triggered by the distress around climate change and security of supply, European countries struggle to diversify their energy portfolio while producing less carbon dioxide (CO2) emissions, favouring a transition to avoid a system collapse. However, this situation is not new. Thirty years ago, prompted by two consecutive oil crises, Brazil started its transition to a less oil-dependent economy, ...

  • Cost-effective use of evaluation models: an empirical cross-national investigation

    Despite the existence of methodologically sound evaluation models for infrastructure projects, it is far from certain if these methods are used at all. In fact, political motives seem often to play a more important role when it comes to "real decision-making". This paper provides an answer to the question of why certain evaluation methods are used as the basis to allocate funds and ...

  • High-level modelling of critical infrastructures' interdependencies

    Due to the increasing demand in services' quality and the growing concerns about external threats, the protection of critical infrastructures has recently become a major concern. In this article, we study the potential effect of interdependencies that may occur between two of these infrastructures: the telecommunication networks and the electrical network. In the absence of side protection ...

  • Factors affecting economies of scale in combined sewer systems

    A generic model is introduced that represents the combined sewer infrastructure of a settlement quantitatively. A catchment area module first calculates the length and size distribution of the required sewer pipes on the basis of rain patterns, housing densities and area size. These results are fed into the sewer-cost module in order to estimate the combined sewer costs of the entire catchment ...
