These models are being used at present to predict the spread of the di sease in most countries worldwide. Studies of COVID-19 are based on theore tical methods for infectious disease dynamics\, which show how the disease spreads. The original model has been used since 1927\, and it classifies the individuals involved in the transmission of the disease into those tha t are Susceptible to the virus\, those who are Infectious and finally thos e who have Recovered. The SIR model was extended and adapted numerous time s to study the progression of other diseases and advanced new techniques. For instance\, modern models include equations to represent Exposed indivi duals (SEIR model). More recent advances defined for modeling the SARS epi demics included behavior for the latency of the disease\, and the effect o f quarantines. Similarly\, studies have investigated the effects of vaccin ation and isolation. These advanced models use network dynamics\, ordinary differential equations\, finite equation theory\, and other theoretical s tudies on infectious diseases. Although these theoretical methods are usef ul to define the theory of disease\, sometimes they are difficult to apply in practice.\n\nAs we have seen in the past few months\, these methods\, based on differential equations\, are useful to predict the number of infe cted individuals\, and to devise different global policies to control the pandemic. Nevertheless\, these methods cannot be easily adapted to include newly available information on the disease\, or to combine them with real world data on demand. Consequently\, large teams of experts need to work together on models of the disease and their simulations\, provide results with limited precision. Another major limitation of the theoretical models under use is the inability for mixing the results of the mathematical mod els with visualization tools and advanced graphical interfaces (including Geographical Information Systems – GIS -\, Building Information Models – BIM -\, and spatial diagrams). Such visualization tools are normally i n high demand for better analysis and decision-making.\n\nWe will introduc e the main characteristics of the Cell-DEVS formalism and will show how to model complex cell spaces using Cell-DEVS with application to COVID-19.

We will then focus on simple models of SIR applied to COVID-19 and will show how to in clude the models of spread of disease at a geographical level\, as well as discussing the definition of models for indoor spread using integration o f BIM software and GIS.\n\nSpeaker(s): Dr. Gabriel A.
