Summary: Resilience is a growing concept in managing engineering systems, but estimating system resilience is challenged by lack of historical data and limited information. Current studies use various indices to quantify resilience, but lack detailed examination of influencing factors. This paper aims to develop a practical methodology using expert judgment and fuzzy set theory to effectively model factors influencing resilience, demonstrated with an underground coal mine fan system.

Summary: This paper proposes a two-stage stochastic repair model that considers uncertainty, and solves the recovery decision problem under large-scale and small-scale disruptions using scenario generation and reduction method and an efficient enumeration algorithm. Numerical experiments demonstrate the efficiency of the proposed algorithm and indicate that the stochastic solution might not be as good as the deterministic solution when a large number of repair time scenarios are considered.

Summary: This study aims to further develop a method for evaluating resilience in energy systems by considering system recovery and introducing new metrics. The findings suggest that all metrics converge to identify the same system as the most resilient, highlighting the importance of redundancy in system design. Additionally, incorporating repairing actions can enhance the resilience of all systems, particularly those with lower inherent resilience. Results also show that operational time and repair probability are key factors in resilience evaluation, indicating that improving repair conditions can be just as effective as including redundancies in system design.

Summary: There is increasing interest in defining and building indicators of resilience for addressing sea-level rise challenges. Most current methods rely on lagging indicators based on historical performance, but there are concerns about their effectiveness in adaptive decision-making across multiple sub-systems and stakeholders. As an alternative, leading indicators based on structural characteristics are gaining popularity for revealing gaps in resilience planning and evaluating adaptation activities. This study presents a survey of literature on these leading indicators in the context of sea-level rise and proposes research directions for incorporating resilience into decision-making on infrastructure adaptation.

Summary: Around 60% of internationally traded gas is transported through pipelines. The success or failure of gas pipelines in Europe is explained by a six condition explanatory framework, including support from involved states, powerful member states, the Commission and the US, as well as the number of stakeholders and technical difficulties. A study on 21 European gas pipeline projects found that support from involved parties, powerful member states and the Commission is crucial for successful construction, while the absence of these conditions has the opposite effect.
