A Mean Field Model for Counter CBRN Threats

In this paper we propose a model to optimize the allocation of resources by a decontamination team facing a CBRN emergency. Due to the possible diffusion of the hazardous or noxious substances in the environment, the team must implement a dynamic strategy which can be seen as a coupling between the countermeasures and the concentration of the threats (which can be seen as a measure of the risk). The aim is to prove the existence of an optimal strategy, and some necessary conditions.
