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.
The critical infrastructure protection domain, through its social implications, is a relatively new research topic, and a science in this regard is not setup yet. Its complexity, through the operational subsumed areas, through the interdependencies and cascading possible effects, through the many facets for investigation, is a special one which imposes specific approaches. This paper intends to continue the investigations in this field, which are conducted in an individual manner or by research teams, by authors with concerns in this regard who agreed to allocate to the topical subject a special attention based on its importance, beyond an exclusive approach – as a special topic. This time, there are brought into attention the issues related to chemical industry sector correlated with actual associated implications of necessary transportation activities in this field. Simulation-based scenario is the main technique employed as a research methodology by using dedicated software.
This article brings to the attention of specialists few points related to an improvement of existing situation in the field of critical infrastructure security through the implementation of advanced technologies and employing a scientific research methodology based on project management. For ensuring the functionality of critical infrastructures, the characteristics of current security environment such as volatility, ambiguity and uncertainty, which determine the use of solutions characterized mainly by the operational agility, have been taken into account. The results of this approach can be useful both for the educational field and for the staff who occupy positions inside the critical infrastructure protection departments within organizations holding or managing such critical infrastructures.
Through this article it is brought to attention the essential aspects related to the perceived risks for critical infrastructure, both theoretically and practically, considering perception as an important input in the risk management process. For the practical part, the added value component in the field consists from the results of research based on survey, conducted in a wider framework of determining the level of awareness of the critical infrastructure issue by a pilot sample, consisting of persons with managerial and operational attributions in this sector.
Critical infrastructures protection research field is booming today because of the practical aspects and sometimes by taking in consideration its imminence character which should be addressed to it. The complexity of this domain originates from critical infrastructures architectures, dominated by the local or regional interdependencies and by the necessity feature of ensuring proper functionality, all in a framework of analysis characterized by unprecedented diversification of physical and / or virtual threats. In this context, this article analyzes (theoretical and based on a practical study) the possibility of using scenarios as a high form of contextual representation method.
