The article focuses on a general interaction scheme of hard- and software of the automation control system for float glass manufacturing process. It proposes a set of programs to identify float glass spot defects using object -oriented pro-gramming environment. Mathematical algorithms of the set implement methods based on the wavelet theory of signal pro-cessing and theory of neural network for localization and identification of float glass spot defects. The article also provid es a structure of the software set to identify float glass spot defects. It describes a software embedding approach as well as the procedure of software deployment in hardware. The authors prove the use of the programs set for identification of float glass spot defects in the control system for high-quality float glass manufacturing process. The software is written in C++ using MS Visual Studio. It is run on an industrial computer based on the fail-safe dual-processor server Fastwel AdvantiX IS-4U-SYS5 with PC_WinRTXEngine real-time operation system.

There are various applications where there is a critical need to reason about moving objects. V.S. Subramani-an offered and F. Yaman (with D. Nau's participation) developed so-called logic of motion (LOM) that provides the formal language including terms of classical logic and Newtonian mechanics. LOM combines propositional logic, constraint sati s-faction and geometric reasoning. LOM has declarative syntax and semantics based on models, and formaliz es reasoning about planned movement of objects. LOM can naturally describe schemes and plans for moving objects and there is a poss i-bility to predict their further locations. LOM consideres objects as material points in space; thus, they have no structure and characteristics (attributes). However, numerous real applications with modeling of moving objects also require a representa-tion of the structure and characteristics of these objects. Also, they require the description of complex objects in terms of simpler ones. G.S. Plesniewicz offered a project of the system "Binary Model of Knowledge" (BMK) for ontological (co n-ceptual) modelling. BMK contains formal languages for structural and logical specification of objects. This paper shows how to integrate LOM into BMK system. LOM and BMK nicely complement each other in applicability and expressive power. Therefore, we receive a system LOM+BMK for ontological (conceptual) modelling of applications considering moving structured objects behavior. A wide range of applications would benefit from using the system LOM+BMR. An example of air traffic control using LOM+BMK is considered.

Means (systems) (MS) of the modern ship are complex systems. Their survivability estimation remains as one of the important scientific and technical tasks. Existing general purpose methods of complex systems survivability estimation require detailed initial data, specific knowledge and skills of users, are labour-consuming and estimate survivability during long operation. The authors consider ship MS survivability as providing a minimal necessary level of the MS functioning to perform a battle task. When performing a fighting task, the influence of various weapons causing MS elements failure is d e-termining. This influence can be considered as one-stage and clear by result and accompanying by secondary damage effects. Comparing to general purpose methods, it allows offering simplier determined approach to the ship MS survivability estima-tion. It is based on the ship electronic model integrated database that contains a structure, communications, characteristics and location of MS and other necessary data to perform calculations. This database also contains calculating results of vari-ous structure variants, location and constructive protection of MS elements using external (determined or probabilistic) battle damage models and emergency processes development. The offered approach consists in forming target logic functions in the aspect of MS survivability estimation; constructing a basic mathematical model using initial data as a focused acyclic graph with functional estimating dependences; and calculating estimating parameters. Combined using of expert systems for ana-lysing MS functions partial performance in certain situations and iterative initial data corrections (including external models operating results) allow taking into account ship MS damage accumulation and investigating both structural and functional components of survivability at the same time. The article gives a general description of the offered approach and its algo-rithms.

The paper describes the solution for the problem of organization and control of cooperation between different services providers and consumers in a solid information space by creating Intermediary Service Provider. It offers a condition management method (contingency management) in a multi-actor integrated information environment as a key control method. The paper describes a problem of controlling an Intermediary Service Provider in service sector and outlines its perfor-mance indicators. Two algorithms to solve described task are proposed. They allow providing expected cooperated behavior of services providers and consumers in a solid information environment with relative independence in decision making. As an example of successful applying of Intermediary Service Provider in tourism, the paper describes software which is de-signed and developed using described approach and algorithms. Implementation of such approach in the problem-oriented software platform form can become a useful tool for specific services providers and consumers who cooperate in solid infor-mation environment. It allows to unlock the potential of information and communication technologies to improve service level.

The work describes a quadric maximum search method on a polyhedral restrictions set. It is based on solving linear equations systems when their dimension no higher than a number of objective function variables. In the beginning, a quadric matrix is worked reduced to a normal view using orthogonal transformations and scaling. Then, using variables re-placement, the initial problem is reduced to a problem of searching the minimum distance between an unconditional extremum point and a polyhedral restrictions set. Perpendiculars to different dimension polyhedron sides are constructed to measure the distance. The special order of sides search is developed to reduce the number of studied sides. The subject to re-search includes only the sides containing the top which is the closest to an unconditional extremum point and seen from this point. If there is not only one closest top, then the side containing all these tops and the sides of lower dimension having not less than two shared closest tops with the first side are investigated.

Nowadays it is a challenging task for the Russian Navy construction to develop an information support tech-nology for a ship life cycle management system. At the same time, practically there are tasks to evaluate the efficiency of in-formation support tools and systems in order to justify resources for their development as well as to define their impact on maintaining the ship’s operational readiness at a certain level. The paper explains selection of an efficiency index for the ship life cycle information support technology. The author suggests using the ship system readiness coefficient as such an index. Unlike technical readiness coefficient, it enables to recognise an impact of factors that do not depend on technical decisions made at ship design stage as well as logistics time required for ship readiness recovery. The article gives a conceptual overview of the key system aspects and target factors that influence the information sup-port system features significantly. There are general conclusions about the need to consider a ship life cycle cost as an independent variable when optimiz-ing parameters (technical, administrative and structural) of the design decisions made at different stages of a ship constru c-tion. In addition, the main requirement for the information support system is that these decisions should be justified based on reliable data and adequate software.

In order to solve a number of applied tasks the classifiers for samples of two -dimensional graphic dependen-cies could be useful. The paper discusses a new approach to solving the problem of graphic dependences classification co m-bining it with the segmentation problem. The article also describes an algorithm of interval consequently enlarged features al-location when the classifier works based on neuron-like hierarchical structure. This classifier is based on the idea of growing pyramidal network that is adapted for work with fuzzy objects descriptions. While learning, the classes models are being formed in the classifier hierarchical structure. The models are interpreted to fuzzy expressions (rules) for fuzzy inference sys-tem. The fuzzy expressions reflect the major characteristics of all objects of training set and are presented in a form unde r-standable for an expert. Features enlarging intervals are obtained by analyzing the rules after training the classifier on prima-ry data. The algorithm of interval features automatic generation allows localizing areas with the same values of fuzzy features. This actually results in investigated graphic dependences segmentation on areas with similar structural properties e s-timation. The operational peculiarities of consequentially enlarged features allocation algorithm are discussed in detail on the example of an artificially generated data. The algorithm software implementation is tested on artificially generated data and on real clinical data (recordings of respiratory sounds, voice and electroencephalograms). The paper studies consistently en-larged features application influence on success of the examined data classification results.

The article presents the results of designing self-adaptive regulators based on the fuzzy-neural networks. Such networks are used to balance the content of silicon oxide in slags when processing copper-nickel ores to copper and nickel cathodes. The paper shows that these metallurgical processes are highly inertial and demand two-level regulation system: rough and exact adjustment. Thus, an exact adjustment can adequately be carried out in completely automatic mode reducing operational loading for actions of a technologist-dispatcher. Operating influences of an independent adaptive regulator provide higher balancing accuracy comparing to manual management. There is a structure of a hybrid fuzzy-neural network which is a base for an adaptive regulator development. The paper shows revealed fuzzy tendencies for dependences of the silicon oxide content in slags from operated parameters of high orders of nonlinearity. They are experimentally proved. The configuration of an author's hybrid network structure includes five interlocked fuzzy-neural subnets with feedback coupling and delay elements. Delay elements simulate the time lag displaying processes iteration depth. The lag in turn also is a fuzzy variable. The given configuration allowed realizing adequately soft operating influences on such parameters as the general sand content; a dust flow; a blasting enrichment; Ni+Cu in a concentrate; S in a concentrate; Fe in a concentrate; SiO2 in a concentrate. Also it is correct to consider a number of retrospecti ve parameters at fo

The article describes principles and examples of cognitive machine graphics for developing Decision Support Systems (DSS). The cognitive machine graphics phenomenon is displaying graphic representations which create spectacular images in the human operator brain. These images stimulate its descriptive impressions, closely related to the intuitive mec h-anisms of thinking. The cognitive effect is in the fact that man perceives the moving projection as three-dimensional picture characterized by multidimensional data properties in the multidimensional space. After the multidimensional data visual as-pects study there appears the possibility for a user to paint interesting separate objects or groups of objects by standard ma-chine drawing. Next user can return to the image rotation procedure to check the intuitive user’s ideas about the clusters an d the relationship in multidimensional data. It is possible to develop the cognitive machine drawing methods in combination with other information technologies. They are the packets of digital images processing and multidimensional statistical analy-sis. The proposed method was based on the idea of possibility to assemble a cognitive image as object in hyperbolic space. In special sense it is possible to say that new kind of DSS – Cognitive Decision Support Systems (CDSS) appear.
