The article describes the previously proposed gate for the realization of systems of functions in the FPGA (field-programmable gate array). Configurable logic blocks (KLB) FPGA contains logic elements (LE) and memory elements (flip-flop). The design of the required circuit is load the FPGA configuration file that defines the function of the LE and the necessary links global and local interconnect matrices. The configuration file is created using computer-aided design, for example, QuartusII Altera company, is transmitted via a special serial interface to the boot ROM are available on-board FPGA. Transferring the configuration file to the FPGA from the boot ROM SRAM memory cell configuration is produced at power. The logic element (LE) has as its basis a read only memory ROM in a tree transmitting transistors, called Logic Cell, and more often - LUT - Look Up Table (LUT - I mean the truth table). However, this LE implements only one logic function. Previously proposed inverse tree to implement the decoder DC, which allows for using additional blocks or custom built to also transmit transistors system logic functions that can significantly reduce the cost of hardware in an amount transistors, a slight increase in latency. Clarifies block structure disjunctions constituents to meet the requirements to activate only one way in the scheme.The simulation DC LUT is executed in the system NI Multisim 10 by National Instruments Electronics Workbench Group. Simulation confirms the efficiency of the proposed scheme DC LUT with a new block of disjunctions.

At the present time is becoming increasingly important research (reference) sig-nals neural networks that can learn to control the object. This article made a study and the procedure for the selection and validation lennogo-defined project design, a model of which can be used as a basis for the development of individual techniques and examines the study of systems with neuro-fuzzy control. In the present article, the authors of specific examples is a block diagram of the study are presented in the language scheme pas chum SCADE Suite individual elements of the management system, as well as a complete system IC route with simulation results. In the proposed structure of the study were tested two methods of adaptation. This method is called stochastic, as well as a method of training the model. For the study of neuro-fuzzy control system is collected separately. In this model system to investigate the feedback control by mistake, the first and second derivatives for different methods of adaptation and different activation functions. Based on the analysis, the structure of the Universe-representation model allows to carry out a full investigation of the neuro-fuzzy control systems for any objects using a variety of feedback signals (on-feedback by mistake, on the first and second derivative of the error) and enables various-WIDE ways to connect and activation units built in compliance with various governmental-activation functions. Upon completion of training neural networks are indispensable tools for solving problems of pattern recognition, approximation optimization, vector quantization or classification.

One of the key problems arising when carrying out scientific researches at the initial stage is the problem of a choice of methods, techniques and methodologies which can be applied in the work. Now system approach becomes a scientific basis and basic methodology of the modern manager. Complication of interrelations, motivations of people, influence of scientific and technical progress - all these processes do the organizations by more and more difficult system. The increasing complexity of relationships, motivating people, the impact of scientific and technological progress - all of these processes make the organization more complex system. The systems approach provides a different vision of efficiency of functioning of organizational systems. It becomes clear the importance of interaction between the structures of the system. In the course of solving complex problems in the management of production is widely used not only to the concept of "systematic approach" and "systematic analysis", dealing with the application of methods and models of systems theory to practice its application to control problems is the most constructive direction systems research. An important function of the system analysis - work with objectives, the study of factors affecting the target formulation, structuring and decomposition of generalizing purpose. System approach gives other vision of efficiency of functioning of organizational systems. There is clear an importance of interaction between structures of system. The system analysis is presented in this article as the methodological tool in the field of quality management of the enterprise, classifications of various methods and techniques of the system analysis which are widely applied in the analysis of activity of the enterprise and management of quality management system of the enterprise are given. Key criteria of formation of quality of the system analysis are defined. Considered in detail the methods of the "tree of objectives", graphical methods, methods of expert assessments, methods such as "Delphi" methods of organizing complex examinations, structuring and statistical analysis, as well as perform the basic steps of these methods. It identified key criteria for the formation of the quality system analysis, namely: the quality of the procedures of the system analysis, urgency and cost effective-ness.

This paper describes issues related to the technological features of foamed glass production. Particular attention is paid to the automation process of the tunnel kiln designed for heat treatment of foamed glass charge, which consists of powdered glass and blowing agent. Besides, the analysis of different raw mixtures for producing foamed glass blocks was performed. The recommended chemical composition of the glass and the description of the different blowing agents were introduced. Focus on the main factors affecting the final product to be used in the construction industry. Relevance of the topic is that it is associated with the automation of technological processes, the result of which is to improve the quality of products and reduce its cost, which leads to increased profitability. Emphasis is placed on single moments relating to the modification of the two-tier tunnel kiln, which promote energy efficiency and uniform distribution of thermal fields in sections of tunnel kiln. Algorithm for moving the crucible in a tunnel kiln is described by mathematical apparatus of marked Petri nets. Object control is carried out by a programmable logic controller. As a programming language used FBD - one of the graphical programming languages. In the form of concrete results of the work done in the article is a piping and instrumentation diagram of two-tier kiln, conditions that trigger sensors, initial state parameters, operations graph of the production process, operation's description of the marked Petri net, transition's description of the marked Petri net, a flow diagram of control system algorithm. The obtained results can be used by enterprises of real foamed glass blocks production.
