Formal Modeling and Simulation for SARS-CoV-2 Containment Scenarios in Catalonia

ABSTRACT

We define interrelated models to simulate the spread of SARS-CoV-2 in Catalonia, which can be used to effectively build simulation applications and analyze the effects of nonpharmaceutical interventions. Due to the constant evolution of this pandemic, and the need to take a multidisciplinary approach, we use a formal specification to represent the model and to validate the model assumptions. We discuss the definition of the model using formal languages, and the Specification and Description Language to improve communication between stakeholders. We show formalization details, discuss implications in the validation process, and present how results obtained from the model of the pandemic in Catalonia can be used for decision-making.
