In this paper, we present a cybersecurity investment supply chain model with nonlinear budget constraints and fixed demands, which gives a generalized Nash equilibrium model. We define the related variational equilibrium and study the associated projected dynamic system (PDS), establishing the relationship between the solutions to the variational inequality and the stationary points of the PDS. Then, we propose a computational procedure to find such stationary points and, finally, some numerical examples illustrate the obtained results.

Abstract

In this paper, we present a cybersecurity investment supply chain model with nonlinear budget constraints and fixed demands, which gives a generalized Nash equilibrium model. We define the related variational equilibrium and study the associated projected dynamic system (PDS), establishing the relationship between the solutions to the variational inequality and the stationary points of the PDS. Then, we propose a computational procedure to find such stationary points and, finally, some numerical examples illustrate the obtained results.
