Special actions (guerrilla, anti-guerrilla, reconnaissance and sabotage, subversive, counter-terrorist, counter-sabotage, etc.) are organized and conducted by law enforcement and armed forces and are aimed at protecting citizens and ensuring national security. Since the early 2000s, the problems of special actions have attracted the attention of specialists in the field of modeling, sociologists, physicists and representatives of other sciences. This article reviews and characterizes the works in the field of modeling special actions and counterterrorism. The works are classified by modeling methods (descriptive, optimization and game-theoretic), by types and stages of actions, and by phases of management (preparation and conduct of activities). The second section presents a classification of methods and models for special actions and counterterrorism, and gives a brief overview of descriptive models. The method of geographic profiling, network games, models of dynamics of special actions, the function of victory in combat and special actions (the dependence of the probability of victory on the correlation of forces and means of the parties) are considered. The third section considers the “attacker – defender” game and its extensions: the Stackelberg game and the Stackelberg security game, as well as issues of their application in security tasks In the “attacker – defender” game and security games, known works are classified on the following grounds: the sequence of moves, the number of players and their target functions, the time horizon of the game, the degree of rationality of the players and their attitude to risk, the degree of awareness of the players. The fourth section is devoted to the description of patrolling games on a graph with discrete time and simultaneous choice by the parties of their actions (Nash equilibrium is computed to find optimal strategies). The fifth section deals with game-theoretic models of transportation security as applications of Stackelberg security games. The last section is devoted to the review and characterization of a number of models of border security in two phases of management: preparation and conduct of activities. An example of effective interaction between Coast Guard units and university researchers is considered. Promising directions for further research are the following: first, modeling of counter-terrorist and special operations to neutralize terrorist and sabotage groups with the involvement of multidepartmental and heterogeneous forces and means, second, complexification of models by levels and stages of activity cycles, third, development of game-theoretic models of combating maritime terrorism and piracy.

Using mathematical modeling, geopolitical, historical and natural science approach, the model of national security. Security model reflects the dichotomy of values development and conservation, being the product of the corresponding functions. In this paper we evaluated the basic parameters of the model and discusses some of its applications in the field of geopolitics and national security.

The paper considers the model of national security, which reflects the dichotomy of values development and conservation, to evaluate its options on the example of Russia (USSR), the United States, Germany and Ukraine. The calculations to assess the safety of the Roman Empire. It is shown that in 160 AD the conservation value of the function has reached a critically low values, which served as the impetus for modernization and reform.

Often decisions in social groups are made by consensus. This applies, for example, to the examination in the technical committee for standardization (TC) before the approval of the national standard by Rosstandart. The standard is approved if and only if the secured consensus in the TC. The same approach to standards development was adopted in almost all countries and at the regional and international level. Previously published works of authors dedicated to the construction of a mathematical model of time to reach consensus in technical committees for standardization in terms of variation in the number of TC members and their level of authoritarianism. The present study is a continuation of these works for the case of the formation of coalitions that are often formed during the consideration of the draft standard to the TC. In the article the mathematical model is constructed to ensure consensus on the work of technical standardization committees in terms of coalitions. In the framework of the model it is shown that in the presence of coalitions consensus is not achievable. However, the coalition, as a rule, are overcome during the negotiation process, otherwise the number of the adopted standards would be extremely small. This paper analyzes the factors that influence the bridging coalitions: the value of the assignment and an index of the effect of the coalition. On the basis of statistical modelling of regular Markov chains is investigated their effects on the time to ensure consensus in the technical Committee. It is proved that the time to reach consensus significantly depends on the value of unilateral concessions coalition and weakly depends on the size of coalitions. Built regression model of dependence of the average number of approvals from the value of the assignment. It was revealed that even a small concession leads to the onset of consensus, increasing the size of the assignment results (with other factors being equal) to a sharp decline in time before the consensus. It is shown that the assignment of a larger coalition against small coalitions takes on average more time before consensus. The result has practical value for all organizational structures, where the emergence of coalitions entails the inability of decision-making in the framework of consensus and requires the consideration of various methods for reaching a consensus decision.

Grid is a new type of computing infrastructure, is intensively developed in today world of information technologies. Grid provides global integration of information and computing resources. The essence Conception of GRID in Azerbaijan is to create a set of standardized services to provide a reliable, compatible, inexpensive and secure access to geographically distributed high-tech information and computing resources a separate computer, cluster and supercomputing centers, information storage, networks, scientific tools etc.
