In the present investigation, an analysis of mathematical models of prediction of the behavior of epidemics in social groups is carried out through an experimental modeling for the propagation of an outbreak of epidemics. For the above, different mathematical and simulation models were reviewed, which developed scenarios that included the analysis of preventive measures, through an agent-based simulation that allowed the projection of the experimental scenarios in the management of epidemics and their impact on the social context. The results show the positive impact of the use of agent-based simulation in the design and evaluation of strategies to control the behavior of contagious diseases in social groups and the orientation for decision-making in the implementation of measures of government agencies. ; En la presente investigación, se realiza un análisis de modelos matemáticos de predicción del comportamiento de epidemias en grupos sociales, mediante una modelación experimental para la propagación de un brote de epidemias. Para lo anterior, se revisaron diferentes modelos matemáticos y de simulación, con lo cual se desarrollaron escenarios que incluyen el análisis de medidas preventivas, mediante una simulación basada en agentes que permitió la proyección de los escenarios experimentales en el manejo de epidemias y su impacto en el contexto social. Los resultados muestran el impacto positivo que tiene el uso de la simulación basada en agentes en el diseño y evaluación de estrategias de control del comportamiento de enfermedades contagiosas en grupos sociales y la orientación para la toma de decisiones en la implementación de medidas de organismos gubernamentales.

Objective: Identify the barriers in the management of the green supply chain in organizations. Methodology: A research scheme was systematized that included a search equation and exclusion criteria. The SCIENCE DIRECT database was used, where 1052 articles were found, of which 27 research articles were selected after applying the exclusion criteria and carrying out the review and selection process of these. Results: 57 barriers that occur in the different industries and organizations were characterized when implementing the green supply chain management, which were classified into 8 categories: financial, administrative or managerial, knowledge, technology and innovation, suppliers and customers , governmental, legislative and social and infrastructure; having as main barriers and more frequently the lack of commitment on the part of senior management, the information gap, insufficient social pressure, deficient legislation, costs and financial limitations that directly impact the management of the green supply chain. Conclusions: Based on the results of the research, it is concluded that there are multiple barriers to implement sustainable practices in the supply chain, which indicate the complex path to sustainability and that requires the effort and participation of all the actors involved in the supply chain. supply directly and indirectly, as well as external actors to organizations such as governments. Likewise, this research contributes to reducing uncertainty in the process of applying sustainable practices. ; Objetivo: Identificar las barreras en la gestión de la cadena de suministro verde en las organizaciones.
