Resilient-to-Fragile Transition and Excess Volatility in Supply Chain Networks
David Martin, José Moran, Debabrata Panja +1
We study a production network in which firms use non-substitutable (Leontief) inputs, hold precautionary inventories and face idiosyncratic productivity shocks, with adjustment occ…
Event-based spatiotemporal networks for modelling emergent phenomena in complex systems
Matthijs Romeijnders, Michiel van Boven, Francesco Corman +3
Complex systems display emergent phenomena that vary significantly across spatial and temporal scales. These variations originate from fine-grained system processes, yet arriving a…
Risk mapping novel respiratory pathogens with large-scale dynamic contact networks
Matthijs Romeijnders, Michiel van Boven, Debabrata Panja
Background: Human-to-human transmission of pathogens fundamentally depends on interactions among infectious and susceptible individuals, yet traditional population-scale models oft…
Critical fragility in socio-technical systems
José Moran, Frank P. Pijpers, Utz Weitzel +2
Socio-technical systems, where technological and human elements interact in a goal-oriented manner, provide important functional support to our societies. Here we draw attention to…
Timeliness criticality in complex systems
José Moran, Matthijs Romeijnders, Pierre Le Doussal +4
In complex systems, external parameters often determine the phase in which the system operates, i.e., its macroscopic behavior. For nearly a century, statistical physics has extens…
