The article discussed the various ways to compare executable files based on their structure, analyzes their advantages and disadvantages. A new way of comparing files different from previous ones with usage blocks of varying size for file descriptions and a new measure of calculating the degree of similarity is suggested. It is experimentally proved the superiority of the method in comparison with existing ones.

The article suggests the technique of structural and parametric synthesis of cyber threats detection system using information and telecommunication systems monitoring data. It is based on multiple criteria analysis methods application and considers peculiarities of cyber threats detection system operation. Calculated example proves the effectiveness of suggested solution.

There are many clustering methods using different approaches to the cluster analysis problem. This paper deals with the greedy cluster algorithm modification. The essence of the modification is that the decision on whether to add a new document to the cluster or not is made on the basis of its similarity to the previously included in a cluster documents. The different optimization versions are discussed. The computing results are presented.

We consider a situational model for delivery route choice and operational decisions in the event of an emergency on the route, the adjustment of support program and choosing a new delivery route. We solve the problem of multi-criteria choice under uncertainty, based on the theory of fuzzy sets. Ranking of multiple routes alternatives is carried out and the best alternative is selected on the basis of fuzzy sets.

The features and prospects of multi-objective evaluation of the parameters of system are considered using the multiobjective optimization methods and software packages. The websites with available software system for solving multiobjective problems are listed. Some single-objective optimization programs which are applicable to evaluate scalarized multi-objective task are considered.

Logical and statistical algorithm based on Boolean, morphological and statistical operations to determine through-pore and using micro still images of composite nonmaterial cross sections is presented. Algorithm was applied for micro still images sequence analysis at different section depths of the silicon carbide composite nanomaterial / yttrium aluminum garnet (SiC/Y3Al5O12) sample, obtained by X-ray tomography.
