The set of parallel algorithms which allow reproducing a complex network as a stochastic graph with probabilistic properties is proposed in the paper. Each of algorithms is based on natural properties of graph structure parallelization and corresponds to features of the certain parallel computer architecture, including systems with the shared and distributed memory, and cluster systems as well. Results of experiments of parallel efficiency on hierarchical parallel computer systems and cluster systems (T-Forge mini) are presented.

The information safety of corporate networks is provided at the expense of use of intellectual means in systems of protection. The giving to systems of protection of biosimilar properties, such as adaptation and selforganizing, testifies to a stage of automation of information safety. It is offered a task of automation of information safety of corporate networks to decide from positions of biosystem analogy: analogies in hierarchical organization of corporate networks, hierarchy of system of protection, field representation of the information and evolutionary processes of inheritance, development, adaptation and selection.

CONTROL OF COURSE MOVEMENTS OF A CAR USING AN ALGORITHM OF SEQUENTIAL OPTIMIZATION Dmitry S. Kabanov, Крашенинников Б. А.
21
We consider the optimal control of the trajectory of a car movement in a horizontal plane. The solution is formed using the algorithm of sequential optimization with the target functional hierarchy. The first functional describes the requirements regarding the angle of the trajectory deflection, while the second one regarding the linear coordinates of the center of mass of the car at the final moment. Moreover, the second functional includes the penalty function characterizing the forbidden areas of traffic defined by the dynamics of the other moving vehicles. We present the numerical modeling results showing that the algorithm of sequential optimization allows solving the problem increasing the traffic safety by avoiding the collisions with the other moving car.

With the purpose of control system fault tolerance it is offered to use multiversion methodology of software design. Multiversion programming supposes the introduction of redundant program modules that essentially raises reliability characteristics of the control system software. However it demands additional resources. The method presented in the paper allows generating multiversion software structure, considering a number of criteria such as software reliability, cost of program component realization, required to the module processor time and so forth. It is presented the approach to definition of weight coefficients on the basis of criteria ranging, that simplifies decision maker work of the criteria importance numerical value ordering.

The possibility of the object imaging on the basis of polarization contrast with the spreading environment (background) is considered. To substantiate given guess there were made measurements of polarization of the light, reflected from the nitro enamel covering. They allowed to fulfill the measurement technique and to consider the distinction of polarizing characteristics of samples and natural coverings. The established distinctions of the polarization mode of completely polarized components and the polarization degree of the reflected light confirm the validity of the assumption mentioned above and can be used for the increase of detection probability of the objects with nitro enamel coverings against the spreading environment.
