Opis:
One of the main tasks of modern hierarchical systems management are integration of technological, organizational and economic management functions and processes. Another important task is creation of unified information space with accurate, complete and current information. Efficient hierarchical systems management requires intelligent processing of large amounts of heterogeneous information. It is appropriate to process information via intelligent components that are built using artificial neural networks. Strategic information about macroenvironments, microenvironments and internal environments are the input data for intelligent components of upper management levels. Intelligent components may solve different tasks which could have features like: large amount of data, data diversity (quantitative, qualitative, text), contradiction and incomplete data, consistency and high intensity of incoming data, high computing amount with dominance of computing operations over logical operations, recursions and regularity of data processing using neural network algorithms, continuous complications of processing algorithms and increasing requirements for results accuracy, possibility to process data in parallel. The method of synchronized spatiotemporal mapping algorithms for intelligent operation component that provides synchronization of data flow intensity with computing intensity (hardware implementation) and takes into account the processor architecture (software implementation) has been designed. It has been proposed to use following principles: conveyor and spatial parallelism in data processing, modularity, specialization, uniformity and regularity of the structure, programmability architecture. during design of intelligent hardware components. Evaluation of structure of intelligence hardware components carried out using test equipment efficiency. Equipment efficiency takes into account number of interface outputs and number of interneuron connections. At the next step it links performance costs of equipment and evaluates elements by device performance. The method for designing of intelligent component management system that uses synchronized spatio-temporal mapping algorithm has been described. Current method takes into account the components, the requirements of the specific application and provides implementation of intelligent components with high efficiency.

Opis:
The article gives results of the development of the system of monitoring for photovoltaic power installations with different configuration to study the factors, increasing their productivity. Differentiation of impact, made by the components of different structure of photovoltaic power installations is made by application of three independent controlled channels of energy extraction from photovoltaic panels: fixed focused, with application of solar tracker and with application of solar tracker, having flat mirror concentrators. To secure originality of the record of the electric energy, produced by photovoltaic panels, we have developed unit of control for discharging current of battery banks in each channel. It supports equal level of their charge. Amount of the produced electric energy in each channel is estimated by the value of discharge. Control and measuring system is made on the base of virtual devices with hardware unit of input/output of NI USB-6009 type, produced by National Instruments Company, with software LabVIEW. In the research, software code of the system of monitoring and front panel of operator have been developed. The work provides photos of the developed experimental stand.

Opis:
A mathematical model for control by transient modes of gas flows in the long-distance gas pipeline is considered in the paper. The long-distance pipeline is considered in the model as the system of Line segments serially connected via compressor stations. Gas motion in such system is described by the non-linear system of equations of gas dynamics. In the frame of this model the integral parameters which determine the expenditure of energy and durations of the transient mode are introduced. These parameters can be used for formulation the problems for optimal control steady-state and transient modes of operation of main-gas pipelines.
