The problem of assorted cargo delivery scheduling in real time is considered at the paper. In practice a transportation of assorted cargo is performed using a priory computed time table and trips. Accordingly the problem is considered as adaptive correction of time table and trips in context of current situation.

The paper provides a discussion about the development of information system to increase citizens’ mobility. The system is also known as system for infomobility. The following questions are discussed in the paper: the system expediency, main system’s features main principles that is used for system development. Additionally, the comparison of existing services that provide infomobility is presented in the paper.

A complex of new models of non-stationary queuing systems with finite source is presented. In contrast to traditional models of queuing theory the proposed models allow to describe the processes of customers servicing in the specified time interval under general assumptions on the time distribution between customer arrival and service. The article presents the principles of such models development, their graphical interpretation and formulae for computation of probabilistic and time characteristics as well as Chapman—Kolmogorov differential equations systems.

For complex industrial facilities providing integrated security is extremely and very important problem for airport facilities (AF). Features AF is a significant set of requirements: aviation security (AS), personnel security, aircraft security and engineering infrastructure. To ensure the functioning of AF for security purposes apply integrated management system (IMS), consisting of the management system set, in accordance with various standards, including international (ISAGO, ISO, ISO/IEC and other). The task seems appropriate to consider a model-based IMS, supplemented both by AS block and comprehensive audits block. In this issue presents the results of calculations according to the presented model IMS with regard to expanded criteria for AF. By a consensus of experts, the requirements of the "base" ISO much lower on the priority of "profile" for AF requirements ISAGO (IATA).

The paper introduces a situational conceptual model designed to investigate complicated spatial systems, Industry-Natural Complexes (INCs) in particular, that provides automation of every modelling stage with possibilities to equally treat information from calculating modules, which simulate parts of an INC, and from integrated GIS and expert system. This approach is featured with wide usage of expert knowledge, employment of the GIS not for object mapping only, but for task setting, spatial-dependent calculations and modelling results' displaying as well.

An approach of providing stability of information technology development in the organization is presented. The essence of the approach is to develop the key efficiency index requirements of IT-processes on the base of balancing their influence on predictable levels of achieving IT purposes by using evolutionary computation methods. This procedure is performed by applying three stages of the developed technique. The specific feature of the procedure is to develop requirements of IT-strategy achievement by estimating their relevance in order to provide a required IT-strategy level and highly robust Holland genetic algorithm with introducing adaptation conditions in terms of assigned outlines influencing the target concepts of the fuzzy cognitive model. The results of using the technique are also demonstrated allowing to adjust IT-strategy and ensure its stability in the given interval of planning and decrease the miscoordination degree between current and required IT architecture state in perspective.

The technique of formalization of fuzzy predicates together with crisp logical variables for the specification of fuzzy logic-dynamic situations and crisp logical commands is considered. The technique is based on the submission of crisp and fuzzy logic variables by means of membership functions and on the use of fuzzy inference rules. Here we only used the forms of presentation of fuzzy logic functions which are also suitable for presentation of crisp logic functions. By the examples the possibility of using the considered technique for the computer implementation of hybrid processes is shown.

Several topical physicochemical issues in the area of high-molecular compounds and biophysics requires real-time registration of the spatial distribution of low-molecular ions. A device utilizing conductometric method based on high-frequency electrode pairs switching in traveling wave mode is proposed for the spatial distribution of low-molecular ion study. Technical features, advantages and applications of the device is described. Results of device testing are presented.

The paper describes the original algorithm of a heterogeneous data clustering is based on complex application of a set of measures of distances and clustering methods and multi-stage clustering. In the algorithm we use ranging of attributes the object on their importance for group and a choice of an optimum attributes set, ensemble approach to get the final clustering solution. The algorithm is realized in MixDC (Mixed Data Clustering) software system. The technique and results of the solution of a real problem of a medical data clustering in software system are described.

In the article review of the existing systems of computer sign language is provided and their advantages and disadvantages are identified. The synchronic aspect of these systems was considered. The general case of translation (both sides) from sounding Russian on Russian sign language and vice versa is observed. A new method for constructing a semantic unit of computer sign language is proposed. Lexical meanings of words are defined to match the correspondence "word-gesture". Among the many words alternatives based on the semantic analysis algorithm for each word necessary lexical meaning is confirmed. For simple sentence semantic analyses algorithms are developed. A translation method of the Russian text into Russian sign language based on a comparison of syntactic structures is proposed. Relevant library is developed to determine the syntax constructions. To create the architecture of the future system for gesture recognition are examined existing hardware and media programs. It is noted that this stage there is no solution that meets the specified requirements, so to get a more accurate result, it is necessary to use a combination of these systems.

The Smart-M3 platform allows constructing software applications consisting of agents that interact by sharing information in a smart space. An important problem is dependability of the application in case of failures, which is a common place for existing networked environments. In this paper, we consider a generic software infrastructure for Smart-M3 applications and propose two solutions to support the application fault tolerance. Our first solution is introduction of a content service, which provides safety of volumetric data and their integrity due to delegation of storage functions to a separate element of the application infrastructure. The second solution is mechanisms for network connections recovery. For experimental case study, we use an existing Smart-M3 application — the SmartRoom system. Based on this case we show effectiveness of the proposed solutions.

Analysis of Intrusion Detection System techniques is a perspective area for the protection of networks and network systems. This paper presence the overview of attack detection mechanisms based on data mining approach. The novelty of the this kind of mechanisms is the ability to create self-learning systems for intrusion detection. Also the article describes the basic elements of intrusion detection algorithms.
