Information and Analytical Model of Product Testing for Counterfeit
The article considers a problem of counterfeit products and the existing methods for solving this problem. An information and analytical method for the optimization of an expert product evaluation is proposed, which uses a parameter set and allows to automate the final decisionmaking process. The set of parameters takes into account not only indicators for suppliers, but also possible consequences of using counterfeit products for different groups of consumers. The method is based on the application of a neural network using a certain base of expert knowledge. Network training is provided during analyzing process with the possibility of correction by an expert. Modeling of the analysis process with different sets of input parameters and various parameters of the neural network was carried out. The results are stored in the database; the neural network performance is evaluated based on these results. The database structure, input parameters structure and the visualization of experimental results are presented. Counterfeit, modeling, evaluation parameter, database, software, neural network.

Modelling of Longitudinal Shock of the Rigid Solid Body to the Rod Interacting With the Rigid Barrier
Shock of a solid body to a rod with a tough barrier on the basis of a wave model of longitudinal shock is considered in numerous papers of domestic and foreign researchers. Various methods of the solution of the wave equation for determination of striking power and the rod stress and strain state are used. However, creation of analytical decisions represents the awkward procedure and, as a rule, it is limited to several cycles of distribution of the created deformation wave from shock section to a tough barrier and back. The procedure is complicated by the fact that the shock system is a mechanical one with unilateral constraints and, in order to analyze the dynamic process, determination of the moment of a contact gap and transition in case of this gap to other mathematical description of the system movement is required. The article considers the wave model of longitudinal shock of a solid body to a rod. The rod is represented by a set of integrated elements of small lengths taking into account wave processes in each element, transformation of waves on borders of elements interface, and unilateral constraints in shock section. Modelling results providing a possibility of the analysis of shock process, formation and distribution of deformation waves in a shock system, creations of charts of the stress and strain state of a rod system at any time point in case of shock are provided. Longitudinal shock, shock wave model, shock to barrier, modelling, deformation waves, deformation wave transmission.

Motion Modes of Shock System for Fluctuating Force Linear Function With Changing Characteristics
Multiple technological processes are often related to using shock systems for performing of cyclic shocks on the object. Research of such systems’ dynamics, stability of motion, shock activity level requires examination of shock processes in systems with different structures. At the same time, a number of problems, confining an area of application of shock systems, arise. They are the following: finding of solutions by exact methods; taking into account complimentary nonliner factors; analysis of transient processes; detection of limit cycles of motion. These problems can be solved by means of developing the effective dynamic system simulation procedures based on the adequate mathematical models, process visualization, and representation and good processing of simulation results. The paper [1] provides an examination of the model of shock system, as well as the definition of its parameters, ensuring a required low of motion. However, a considered piecewise constant force impact may be applied to an ideal situation that is difficult to implement with a real system. Thus, it is required to know how the change of force impact would effect the mode of striker’s motion. The present paper deals with a model for shock system at force impact as linearly increasing and linearly decreasing function when force impulse, duration and period of the force impact are constant as at the piecewise constant function. A mathematical model for the shock mass motion under condition of collision with rigid barriers is given. The modeling of shock system motion at the forceimpact piecewise constant, linearly increasing and linearly decreasing function is implemented. The comparative analysis of presented simulation results is performed. The motion mode of shock system at linearly increasing and linearly decreasing functions has been changed against the mode at the forceimpact piecewise constant function (although the force impulse was constant in both cases). Following the results of implemented work, it may be deduced that the changing the force linear function characteristics, when impulse and duration of force, and part of cycles are constant at an appropriate systemparameter option, does not misrepresent the cyclic mode of shock mass motion if the process would be estimated at such criteria as velocity of shock to the right barrier, implementing of one impact per a cycle at the maximal velocity, and a cyclic behavior of impact. Shock system, motion modes of shock system, limit cycles of motion, modeling, cyclic mode of motion.

Formalization and Mathematical Modeling of the Avionics Systems Requirements for Automation of Test Design
The article deals with the automation of test design for avionics systems. The automation of test design is proposed to be made on the basis of formalization and modeling of the requirements for them. The design process accelerates when using offtheshelf modules in the product, but their use imposes more stringent requirements for the product requirement design and management, which are the basis for the product planning, management, acceptance testing, and adjusting. Based on the classical Vmodel for product definition within complex projects, the paper shows that the requirements are closely related to testing, which is directed at defects identifying and avoidance in the system, at this, the defect is regarded as a deviation from the requirements. The article gives an example for formalization and modeling of the requirements for aerobatic display frame information in an integrated system of electronic display and alarm. Based on the resulting model and the formal submission of the requirements the structure of the final test for the system is compiled. The proposed approach allows us to reduce time for testing and debugging the system, improve its quality in the sense of greater compliance. Modeling, system requirements, testing, formalization, program of operation.
