Abstract:The resource management in a dynamic environment is a really complex problem. If semantic constraints are taken into account the complexity increases significantly. The problem definition of resource management using semantic constraints in the subject domain is demonstrated by means of an example of manufacturing scheduling. The application of multiagent approach is suggested and examined to solve the resource management problem. Experiments simulate two types of calculations of the resource allocation proble… Show more
“…To solve this problem numerically, it is sufficient to define a cycle which repeatedly searches for the root of Eq. ( 16) at a given resolution (U step), and registers the amperage for that given voltage [2,3,8,10,15,17,22,24,27,28].…”

Many factors determine the efficient operation of a photovoltaic cell. These factors can be the intensity and spectral composition of illumination, the surface temperature, the ambient temperature, and the amount contaminations in the air and on the surface of the cells. The aim of the present study is to describe the effect of temperature gradient on the voltage and amperage changes, as well as the power output of a commercial solar cell through experimental methods and numerical simulations performed in MATLAB. The transient temperature investigations have allowed better understanding the time-dependent behavior of a solar cell under constant intensity illumination. Measurements prove that an increase in the surface temperature of the solar cell significantly reduces its performance. Measurements performed with the solar simulator show good conformity with simulated results.

“…Figure 7 shows a polycubic olap model for a complex analytical task built by the user. The OLAP model consists of data sources, DataStore, OLAP cubes, and result presentation [24,25,28]. The characteristics of the OLAP model include: the power, dimension, volume of the hypercube, where the power of the hypercube is the product of the power of its measurements, and the volume of the hypercube is the product of the power of the cube and the number of indicators.…”
This work proposes a technique of presenting a system model of a subject area in the form of a category of processes. The rule of synthesis of self-organizing structure of process models is proposed. It is shown that the sequence of process decomposition compositions has the property of fractal transformations (self-like). The core of these transformations are commutative triangles that define the structure of interacting processes in composition-decomposition. Such structures have been shown to retain the properties of self-organization in accordance with the laws of the required diversity of the EShBI. The possibility of building a number of identical formal algorithms of control of integrity of the structure of initial processes, in case of violation of which "external" control is required, is shown. The proposed transformation is demonstrated by the example of synthesis of the self-organizing process of the agreement, the architecture of whichб is defined in ISO/IEC 15288 standard "System Engineering." Polycubic data organization for a software system is proposed herein.
The paper deals with the problem of resource management in manufacturing scheduling. The authors consider the problem definition of resource management using ill-formalized constraints of non-numerical nature ("semantic domain constraints"). It is suggested to use intelligent data processing technologies resource management in manufacturing scheduling. This technology is based on multiagent approach. The main idea is to represent the process of solving the task of resource management as a sequence of negotiations or communication interactions of agents. The behavioral algorithms for the main agents was developed: "detail", "operation", "resource".
