Actual scientific approaches related to critical infrastructure reveal its importance within many of the society’s essential services that are necessary for day-to-day people’s life. Besides other critical infrastructure systems, the emerging development of the space system results in the embedment of it within the critical space infrastructure concept that is based on its description related to the importance of the services provided to population, public or governing institutions, and industry. This paper intends to present the manner in which the space system services influence population’s life and to emphasize the importance of the space infrastructure related to the process of planning and conducting military operations. The reliability and well functioning of the space system from the perspective as a critical infrastructure proves its paramount importance related to essential services provided to the population that results into social well-being. Nowadays, the majority of military operations depend on the development of space infrastructure and its reliability. Moreover, the military space operations are based on satellite control system architectures as well as the interconnected systems on surface and underground systems. From this side, the protection of critical space infrastructure and its resilience level should have a paramount value for all stakeholders that are using the space system services.


The urban transportation system is characterized by the urban roads development and growth of road traffic, which leads, most of the time, to a series of congestions in the vehicles traffic. Consequently, due to a high time duration spent on the road traffic, the travel time from a location to another one could be very upsetting for any car drivers, or embarrassing for emergency services and vehicle convoys that carry goods or sensitive items. Those are mainly reasons for using simulation modeling to analyze and optimize the travel time of the road traffic actors in the an urban transportation system. This paper focuses on optimization vehicles flow in a crowded area of Sibiu city, by using agent-based modeling concept and AnyLogic simulation modeling software.
