“…Программистский способ получения случайных чисел -в ЭВМ используется некоторое рекуррентное соотношение: каждое последующее число происходит из предыдущего (или группы предыдущих) при помощи использования алгоритма, состоящего из арифметических и логических операций. Так, к примеру, простейший арифметический расчет, предложенный Нейманом, заключается в том, что берется некоторое произвольное число, состоящее из двоичных цифр, и возводится равным квадратом [10]. По итогу мы получили число, состоящее из цифр, в котором после каждого последующего выбрасывается по одной цифре с обоих концов (остается «середина произведения»).…”

In this work is considered information systems: its structure and influencing factors of the external environment that allows to describe its simulation means. Elements for the description of similar systems are algebraic differential equations, Markov chains or similar of the Research objective consists in forming of conditions of carrying out a natural experiment not on the studied system, and on some other (with the known distribution parameters of the studied random variable, for example, of the distribution law), rather “similar” to given and such which experimental functioning will not lead to a little notable costs. Research methods. At simulation of processes of Markov the difficulties connected with need of input in memory of the machine of stochastic matrixes of infinite dimension very often meet. It is actually very difficult to present an infinite stochastic matrix in which all elements are selected “purely accidentally”, i.e. without any patterns. In practice there are always only such matrixes in which, since some line, a certain pattern in formation of elements is shown. The solution of the specified problem is based on this property. Results. The algorithm of finding of a random variable consists in the choice of that from expressions which at this value is true. Then the following implementation is on the formula corresponding to the selected expression. If at the same time the selected formula contains a random variable, then by means of already known receptions there is implementation of this random variable and is substituted in it. To be convinced of correctness of the offered algorithm and to understand reasons on the basis of which expressions are constructed it is enough to substitute all possible values of random variables and to compare result to received by means of a matrix. The considered logical reception is applicable also at simulation of behavior of the objects, more difficult, than a Markov chain. Its use in more difficult situations – a component of the idea of automatic modeling of information systems. Conclusion. The algorithms of forming of pseudorandom numbers received in work for simulation of components of an information system are rather adequate, however their efficiency is defined by the relation of a part of the square of a rectangle located under a curve to all its area. If this relation is not enough, then a considerable part of machine time is spent for unproductive receiving the accidental points lying under a curve and discarded in the course of calculations. From here follows, in particular, that for exponential distribution the specified method least, and for uniform is most effective. In practice it is reasonable to use such method when the specified relation exceeds value 0.3. In certain cases it can be applied and when this relation more than 0.1.

In this work the task is formulated and the method of reconfiguration of systems of organizational management on the basis of synthesis of the functional structure having an impact on an appearance of all system considerably defining an order of its functioning, integrating in a whole of means of technical and mathematical, program and information support is offered. The research objective consists in need of increase in effective management of organizational systems on the basis of complex development, implementation and application of funds of automated management of its elements. Expert systems on the basis of declarative programming languages are applied to synthesis of similar structures. Research methods. As the tool for definition of the knowledge base about the field of restructuring of structure of management calculation of expressions and language of a predicate logic, that is a logic theory of first order is used. Then, the problem of reconfiguration of hierarchical structure of management system can be presented doubly. First, as a problem of definition of the changes of the known rational hierarchical structure providing minimum loss from the arisen functional failures. Secondly, as a problem of creation of new rational structure which provides optimum use of the resources used in the course of achievement of definite purposes in the changing conditions. Results. As a result of a research, on the basis of de Morgan's law the factors influencing a system status of organizational management in general are defined. The necessary structure of solvable tasks of all hierarchical structure is defined by extent of influence of different factors on characteristics of structure of management. Conclusion. Work of the received expert system consists in consecutive execution or failure to follow rules and transition from one status to another. In case of an impasse the expert system gives the report in the form of requirements of alternative change of these or those rules (factors). New rules are remembered. Thus, the system of knowledge is increased.
