    Operational Research: Methods and Applications

    Get PDF
    Throughout its history, Operational Research has evolved to include a variety of methods, models and algorithms that have been applied to a diverse and wide range of contexts. This encyclopedic article consists of two main sections: methods and applications. The first aims to summarise the up-to-date knowledge and provide an overview of the state-of-the-art methods and key developments in the various subdomains of the field. The second offers a wide-ranging list of areas where Operational Research has been applied. The article is meant to be read in a nonlinear fashion. It should be used as a point of reference or first-port-of-call for a diverse pool of readers: academics, researchers, students, and practitioners. The entries within the methods and applications sections are presented in alphabetical order. The authors dedicate this paper to the 2023 Turkey/Syria earthquake victims. We sincerely hope that advances in OR will play a role towards minimising the pain and suffering caused by this and future catastrophes

    Recommendations for National Risk Assessment for Disaster Risk Management in EU

    Get PDF
    Decision No 1313/2013/EU on a Union Civil Protection Mechanism (UCPM) calls Participating States to develop risk assessments periodically and make the summary of their National Risk Assessment (NRA) available to the European Commission as a way to prevent disaster risk in Europe. In order to facilitate countries on this task, the European Commission developed the Guidelines on risk assessment and mapping. In spite of these, the summaries received have revealed several challenges related to the process and the content of the assessments. The current report aims to provide scientific support to the UCPM participant countries in their development of NRA, explaining why and how a risk assessment could be carried out, how the results of this could be used for Disaster Risk Management planning and in general, how science can help civil protection authorities and staff from ministries and agencies engaged in NRA activities. The report is the result of the collaborative effort of the Disaster Risk Management Knowledge Centre team and nine Joint Research Centre expert groups which provided their insight on tools and methods for specific risk assessment related to certain hazards and assets: drought, earthquakes, floods, terrorist attacks, biological disasters, critical infrastructures, chemical accidents, nuclear accidents and Natech accidents. The current document would be improved by a next version that would include scientific guidance on other risks and the collaboration of potential users.JRC.E.1-Disaster Risk Managemen

    The relative performance and consequences of protecting crowded places from vehicle borne improvised explosive devices

    Crowded places have been the target of terrorist attacks for many years. Their inherent nature has resulted in a vulnerability to a range of attacks, most notably the threat of vehicle-borne improvised explosive devices (VBIEDs). Government agendas have been seeking to reduce the extent of this vulnerability, by encouraging those who are responsible for the design, construction and operation of such places to incorporate counter-terrorism measures (CTMs) into their designs, and where necessary, retro-fit them into existing places. However, little is known about what measures can be used, as well as their performance and consequences. The aim of the research is therefore to identify the aforementioned range of measures through the development of a typology that also examines their relative performance and consequences for a range of scenarios, in order to inform key decision makers who are responsible for the protection of crowded places. Through the use of a qualitative research strategy and respective research methods, interviews, site visits and document analysis were carried out in both the UK and in the USA. A total of 47 participants were recruited for the research, with the collection of data spanning 16 months. A preliminary study was undertaken that determined a range of influences on whether crowded places are protected, as well as influences on the value of CTMs themselves. A theoretical framework was developed to capture and understand those influences. Conventional data analysis methods and internal validation techniques were used to subject the data to methodological rigour, ensuring the validity and reliability of the research. While the negative consequences of incorporating CTMs can be profound, every CTM that can be used has additional benefits; measures can be incorporated at no cost and can even generate revenue; and designing-in CTMs has a number of advantages over retro-fitting them. This research s contribution to knowledge in relation to methodology, empiricism, theory, industry, and policy has resulted in the creation of a significant amount of guidance for key decision makers who are responsible for the design, construction and operation of crowded places, as well as providing data on the benefits that can be gained from incorporating mitigative measures that is of interest to those who have a role to play in the design, construction and operation of the built environment more broadly. Recommendations for further research posit that greater understanding is needed in relation to the specific monetary costs of CTMs themselves, the experience of users of protected places, the implications of invisible CTMs, and the need for research into the assessment and incorporation of proportionality into the built environment. Practical recommendations put forward the need for clarification of legislation in relation to duties of care, the dissemination of the incentives to protect, and benefits of protecting, crowded places, the need for further debate and transparency regarding proportionality and what constitutes proportionate design, and the need to encourage greater engagement between stakeholders and the means through which this can occur. The research posits that legislative requirements encompassing the mitigation of terrorist attacks are apparent, and that therefore, organisations should incorporate CTMs into vulnerable places, yet as previously indicated, such CTMs do not have to cost anything

    Smart Cities and Construction Technologies

    Get PDF
    This book includes nine chapters presenting the outcome of research projects relevant to building, cities, and construction. A description of a smart city and the journey from conventional to smart cities is discussed at the beginning of the book. Innovative case studies of underground cities and floating city bridges are presented in this book. BIM and GIS applications on different projects, and the concept of intelligent contract and virtual reality are discussed. Two concepts relevant to conventional buildings including private open spaces and place attachments are also included, and these topics can be upgraded in the future by smart technologies

    A Survey of the European Security Market

    Get PDF
    This document synthesizes the results of the research made on the European security market. It deals with questions of interest regarding the provision of security goods and services for protecting society from terrorism and organised crime. It explores issues such as market revenues, demand and supply, industrial capabilities, technology, research and development, innovation, business strategies, competition as well as market structure, agents' conduct and economic performance. The research has been based upon desk analysis of open source information related to the security market. Economic theory and critical analysis has been applied to understand the gathered information, derive knowledge, point out key issues and assess trends and drivers that will likely shape the sector's future. The study is the outcome of the working package number 5 included in the research project A new Agenda for European Security Economics (EUSECON). This project with code number 218195 has been financed by the European Commission within the 7th European Research Framework Programme. The task has been performed by the company ISDEFE according to the scope and work plan described in the EUSECON proposal. The author wishes to express his appreciation to all the individuals that have provided input and valuable comments to this study, including anonymous referees.
