The authors propose the development of a framework using simulation modelling technology. The aim is to simulate the behavior and the interaction and interoperability of the components of the modern communication infrastructure of the national security systems in various crises. The focus is on cyber security and cyber defence, from the point of view of risks and threats to the security of communication infrastructure such as disasters and other crisis situations.

The basic principles of functioning of subsystems of the information-technological complex, which is intended for the forecast of structure and properties of the cast metal, are presented. The basis of subsystems are mathematical and simulation models of crystallization. The subsystem of thermal analysis is based on mathematical models, which were developed within the framework of the dynamic theory of metallic castings The subsystem of modeling of crystallization is based on a combination of mathematical models of heat conduction and diffusion with cellular automata. The model makes it possible to investigate in computational experiment the effect of various cooling conditions on the process of formation of the structure during crystallization. The results of computer experiment are shown.

The hypothese concerning encoding of information in the peripheral part of the human’s auricular analyzer are presented. A brief critical analysis of contemporary trends in theoretical concepts concerning principles of work of the cochlea of the inner ear are conducted. Prerequisites for the construction of an alternative theory of coding of information in it are formulated in order to optimize the design and software of cochlear implants. The principle of constructing an imitation model of the generation of electric signals formed in the cochlea of the inner ear are proposed.

The paper describes the methods for the design of systems for implementing intelligent control of transshipping processes at the seaport. Movement of cargo flows requires a constant solution of singular case transportation problems of operational planning and management. The paper shows how the obtained mathematical models of management of cargo flow movement processes, allow for solving optimization problems of the divergent options of bulk cargo movement within the Functioning of infrastructures within a seaport, as well as their communication with suppliers and consumers of loads within the transshipping complex. Modeling of different options bulk cargo movement is needed for providing the given intensity of ship loading taking into account various factors, including weather. The designed model allows for solving the scheduling problems the execution of works on cargo handling in the seaport terminals.
