Concurrentierisicos

Concurrentierisicos is a multidisciplinary concept used in risk analysis and system engineering to describe risks that arise from multiple, interacting factors occurring at the same time. The term is a neologism that reflects the study of how simultaneous hazards interact, amplify, or dampen each other within complex systems, rather than acting in isolation. It emphasizes interdependencies, nonlinearity, and potential cascading effects that can transform multiple small risks into a major event.

Origins and use: The concept has emerged from fields such as resilience engineering, systems thinking, and quantitative risk assessment, where traditional univariate risk models are insufficient for capturing combined effects.

Analytical approaches: Probabilistic risk assessment, multivariate statistics, Bayesian networks, copula models, fault and event tree analysis, Monte Carlo simulation, and agent-based modeling. Data challenges include sparse event histories and uncertain dependencies; practitioners use scenario analysis and stress testing to explore extreme but plausible combinations.

Applications: critical infrastructure protection (power grids, water systems), manufacturing and supply chains, financial risk management, health care and public health, cybersecurity and information systems.

Limitations and relation: It can be data-intensive and computationally demanding; risk of overfitting; requires interdisciplinary collaboration; related to systemic risk, cascading failures, and resilience engineering.
