U travanjskom broju znanstvenog časopisa “Pomorstvo” Pomorskog fakulteta u Rijeci, bit će objavljena dva znanstvena rada koautora dr.sc. SaÅ¡e Aksentijevića:

• Aksentijević, SaÅ¡a; Tijan, Edvard; ÄŒiÅ¡ić, Dragan: “Modeling of economically sustainable information security management systems in seaport clusters“

Sažetak: “The paper researches the usage of simulation approach using FlexSim software package in order to create a viable model of administrative document flow during ship arrival and departure in conventionally operated seaport clusters that do not utilize Port Community Systems. Goal of the modeling was to create a simulation model that would be used to reliably calculate the average total time required for the full document flow related to ship’s arrival and use the end result to estimate the cost of labor related to involved manual work. This estimation will be used as a basis for further research into possibilities of process reengineering and suggestion for process improvements.”

Keywords: seaport clusters, simulation, administrative costs, information management

•  Tijan, Edvard; Aksentijević, SaÅ¡a; Hlača, Bojan: “Simulation of administrative labour costs in seaport clusters“

Sažetak: “The paper researches the usage of ARIS Express process modeling tool in creation of economically sustainable information security management system in seaport clusters. Basic concepts of information security in seaport cluster stakeholder’s organizations are detailed, and relations and interactions between organizations and their environment are researched. Portfolio approach to information security is being endorsed along with quantification of total levels of the risk and the resulting cost of information security. The authors identify two basic process paths of information security in seaport clusters: basic activities and supporting activities. Furthermore, main components of both are being researched in detail, along with their interactions that create a robust system of information security management in seaport clusters. Process flow of all activities is constructed by using business process model implementation of ARIS Express software.”
