Failed disruption propagation in integer genetic programming
Proceedings of the Genetic and Evolutionary Computation Conference Companion, 2022 We inject a random value into the evaluation of highly evolved deep integer GP trees 9743720 times and find 99.7percent Suggesting crossover and mutation's impact are dissipated and seldom propagate outside the program. Indeed only errors near the root node have impact and disruption falls exponentially with depth at between exp(-depth/3) and exp ...

Propagation of International Supply-Chain Disruptions between Firms in a Country [PDF]
Journal of Risk and Financial Management, 2021 This study shows how import and export shocks propagate through domestic supply chains using actual Japanese supply-chain data and a world input-output table (WIOT) based on firm-level agent-based simulations. We propose three different models with which to connect the domestic firms to a WIOT. Then, we estimate the value-added losses of Japanese firms

Recovery time and propagation effects of passenger transport disruptions [PDF]
Physica A: Statistical Mechanics and its Applications, 2018 We propose a method to evaluate public transport network vulnerability. We study the evolution of the passenger Volume Over Capacity (VOC) ratio throughout the network to measure the spatial and temporal extent of the impacts caused by an unplanned service segment disruption.

An interactive bi-disruption model for marital instability with stability analysis
Scientific African, 2023 Marital instability has a devastating effect on our society. In general, marital disruption results in negative physical and psychological health outcomes, as well as adverse economic consequences for children, adolescents and adults.

A Stochastic SEIQR-Based Model for Disruption Propagation and Resilience in Transport Logistics Networks [PDF]
E3S Web of ConferencesThis paper presents a stochastic modelling framework based on the SEIQR epidemic model to analyse the propagation of disruptions and the dynamics of resilience within transport logistics networks. Each operational unit in the network—such as a warehouse,

Disrupting antibiotic resistance propagation by inhibiting the conjugative DNA relaxase [PDF]
Proceedings of the National Academy of Sciences, 2007 Conjugative transfer of plasmid DNA via close cell–cell junctions is the main route by which antibiotic resistance genes spread between bacterial strains. Relaxases are essential for conjugative transfer and act by cleaving DNA strands and forming covalent phosphotyrosine linkages.

Time Granularity Impact on Propagation of Disruptions in a System-of-Systems Simulation of Infrastructure and Business Networks [PDF]
International Journal of Environmental Research and Public Health, 2021 A system-of-systems (SoS) approach is often used for simulating disruptions to business and infrastructure system networks allowing for integration of several models into one simulation. However, the integration is frequently challenging as each system is designed individually with different characteristics, such as time granularity.
