U radu je prikazana primena nove metode višekriterijumske komparacije graničnih aproksimativnih oblasti-MABAC. Osnovna postavka metode ogleda se u definisanju udaljenosti kriterijumske funkcije svake posmatrane alternative od granične aproksimativne oblasti. Granična aproksimativna oblast definiše se posebnim postupkom za svaki kriterijum i zavisi od vrednosti svih alternativa po posmatranom kriterijumu. Metoda je prikazana kroz šest jednostavnih koraka u podršci odlučivanja upotrebe snaga u odbrambenoj operaciji. Za definisanje kriterijuma i njihovih težinskih koeficijenata iskorišćena su ranija istraživanja.
This paper analyses the application of Bass's diffusion model in forecasting the number of telecommunication services users in the event of natural disasters. Citizens' behaviour has been modelled in the case of an emergency situation caused by an earthquake with high magnitude. We analysed the area of an administrative district in the south-west part of the Republic of Serbia which includes two cities and three municipalities. To control the consequences of natural disasters, a unit of the Army of Serbia with the required number of radio transceivers for establishing communication between the vulnerable population and rescuers with command staff at the observed territory has been dimensioned. Special emphasis is given to the provision of telecommunication support in the military assistance in a relief operation with civil authorities.
Starting from the fact that perceptions of employees might be related to national culture and our previous finding that CSR perception by employees depends on company ownership, in the present research, we aim at the investigation of relations between CSR and national culture perception by employees’ dependence on company ownership in the specific context of Serbia as a developing post-socialist country. Questionnaire-based research was conducted among employees in public and private companies in Serbia with domestic and foreign ownership. The results pointed out that both CSR and national culture perceptions are highly dependent on company ownership with the dependence of CSR perception on national culture perception by employees in public but not private companies. The obtained results point out that in private companies, excessive adoption of managerial practices not aligned with national culture resulted in shifts in perception of national culture, as well as in divergence between national culture and perceptions of CSR activities.
This paper presents a model of communication and information system in military operations. Here OPNET MODELER simulation package is applied because it is suitable for network modelling, topology and capacity planning. Simulation of different types of IP traffic and monitor their performance to optimise the functionality of network elements, management performance network applications, and as well as in research and development of new network technologies. Application of the method of mass service are determined by the capacity needed for voice transmission on the links in the model and using the OPNET MODELER simulation program are analysed performance modeled communication information system in data transmission. The results of the simulation are presented through target the service settings: workload links communication and information system, e-mail download response time, http page download response time and packet loss in data transfer. The aim of the research has shown that modeled communication information system with defined elements (nodes), the capacity of links (according to the specification of telecommunication devices) and defined traffic can respond to the requirements of command forces in the military operation in terms of telecommunication service. The results of the analysed service target parameters show that modeled communication and information system provides an efficient flow of information and the tra nsfer of voice and IP data for the needs of command and control in military operations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
