Formal and computational modeling of anticipation mechanisms of resilience in the complex sociotechnical air transport system

With ever-growing numbers of passengers and complexity of the air transport system, it becomes more and more of a challenge to manage the system in an effective, safe, and resilient manner. This is especially evident when disruptions occur. Understanding and improving resilience of the air transport system and its adaptive capacity to...

Evaluation of a Multi-Agent System approach to airline disruption management

Each day, airlines face disturbances that disrupt their carefully planned operations. Events like adverse weather conditions, sick crew members, or damaged aircraft often result in delays in the airline's schedule. An airline recovers from such disruptions through the role played by its Airline Operations Control (AOC). A Multi-Agent System ...

A Greedy Scheduling of Post-Disaster Response and Restoration using Pressure-Driven Models and Graph Segment Analysis

In this manuscript, we consider the problem of optimally scheduling the restoration of a water distribution network with multiple failures after a disaster. The decisions made are the sequence of burst/broken pipes and leaks that need to be replaced or repaired, respectively, subject to constraints on workforce availability and physical...

Modelling the resilience of rail passenger transport networks affected by large-scale disruptive events: the case of HSR (high speed rail)

This paper deals with modelling the dynamic resilience of rail passenger transport networks affected by large-scale disruptive events whose impacts deteriorate the networks’ planned infrastructural, operational, economic, and social-economic performances represented by the selected indicators. The indicators of infrastructural performances...

The Brisbane Declaration and Global Action Agenda on Environmental Flows (2018)

A decade ago, scientists and practitioners working in environmental water management crystallized the progress and direction of environmental flows science, practice, and policy in The Brisbane Declaration and Global Action Agenda (2007), during the 10th International Riversymposium and International Environmental Flows Conference held in...

Modeling dynamics and adaptation at operational and structural scales for the ex-ante economic evaluation of large dams in an African context

Dams can produce electricity and ensure water security, but at the same time they radically alter the hydrological regime of rivers with significant consequences for the economic and environmental welfare of the region in which they are located. Cost-benefit analysis (CBA) is currently the most frequently used framework for the economic...

Influence profile of wastewater chain in Amsterdam: Towards resilient system for phosphorus recovery and Valorisation

The wastewater system of Amsterdam offers an opportunity to recover phosphorus, and contribute to circular economy. However, it remains unclear where to intervene in system to maximize recovery and valorisation in a resilient and feasible way. The Design Structure Matrix method was tested to define the system architecture from Food-Water-Energy...

Resilience in practice: Five principles to enable societies to cope with extreme weather events

The concept of resilience is used by many in different ways: as a scientific concept, as a guiding principle, as inspirational ‘buzzword’, or as a means to become more sustainable. Next to the academic debate on meaning and notions of resilience, the concept has been widely adopted and interpreted in policy contexts, particularly related to...

Between aspirations and reality: Making farming, food systems and rural areas more resilient, sustainable and equitable

This paper explores the connections between farm modernisation, rural development and the resilience of agricultural and rural systems. The paper starts by ascertaining why agricultural and food systems need to change systemically. Evidence from case studies in fourteen countries is used to explore the possibilities for, and drivers and...

A methodology for road traffic resilience analysis and review of related concepts

Major and minor disturbances can have a considerable impact on the performance of road networks. In this respect, resilience is considered as the ability of a road section to resist and to recover from disturbances in traffic flow. In this contribution, an indicator is presented, the Link Performance Index for Resilience (LPIR), which evaluates...

On Centrality-Related Disaster Vulnerability of Network Regions

Networks are typically embedded in non-homogeneous areas and different parts/regions of the network may therefore be at risk from different types of disasters. This non-homogeneity leads to difficulties in protecting the network against (the risk of) disasters. Network operators need to be able to integrate predictions on possible future...

State of the Art in Technology-Supported Resilience Training For Military Professionals

Certain professions carry a risk of experiencing traumatic events and sometimes developing Posttraumatic Stress Disorder (PTSD). Researchers have been working on strategies to prevent professionals in those fields from developing PTSD. Recently, there has been a focus on applying technology that supports these preventive strategies, especially...

CIAM 8. The Heart of the City as the symbolical resilience of the city

The “Heart of the City”, title of the 8th CIAM held in 1951, is a contradictory and pervasive figure of speech which has marked a thinking and urban transition after the Second World War. In 1951, two opposite urban conditions are considered by Sert, President of CIAM, as main issues which the discourse on the Heart should face: the...

Agent-Based Modelling and Simulation of Safety and Resilience in Air Transportation

Purpose: In order to improve the safety, capacity, economy, and sustainability of air transportation, revolutionary changes are required. These changes might range from the introduction of new technology and operational procedures to unprecedented roles of human operators and the way they interact. Implementing such changes can introduce both...

Quantitative Geotechnical Risk Management for Tunneling Projects in China

To date, the tunneling in China is experiencing an age of fast development for decades. The potential risks behind the huge amount of construction and operation works in China was first formally realized and managed after 2002. The transition of risk assessment from a qualitative manner to a quantitative manner is on the way from the research...

The Resilience Value of Public Transport Development Plans

Investments in transport are increasingly motivated by the need to improve its resilience – the overall capability to maintain system integrity and functionality. Nonetheless, there is lack of knowledge on how to assess their impact on network resilience. This study investigates the resilience of alternative public transport networks by...
