Use of the Specification and Description Language SDL and SDLPS to Define and Simulate Complex Systems. Case Study: Spread of COVID-19 in Ecuador.

Abstract

The Specification and Description Language (SDL) is a formal object oriented language for distributed systems which is widely used for the simulation of complex systems such as propagation of epidemics like COVID-19. SDLPS is a simulation tool that is used for testing complex systems implemented with SDL. Cellular Automaton is a mathematical and computational model applied to dynamic systems that evolve in discrete steps; and Intelligent Agents that are entities capable of perceiving an environment, process or perceptions and respond in a rational manner. The objective of this investigation was simulate the COVID-19 behavior in Ecuador based in SDL language, SDLPS tools and SEIR models using the real data published by the Ministry of Public Health of Ecuador from March 2020 to December 2021. The model for Ecuador was based on the model developed by Dr. Pau Fonseca i Casas and configured to responds to the specific variables of Ecuador. The main conclusion was that SDL and SDLPS are very important tolls to develop and simulate complex systems like propagation of epidemics. It was necessary to validate this investigation with others case studies.
