The urgent line of development of the baking industry is the development of new formulations and resource-saving technologies of bread products for dietary nutrition. To create new types of a wide range of ahloridny products, it is preferable to use non-traditional raw materials of vegetable origin: whole-wheaten wheat flour, buckwheat and whey beverage flour “Actual”. An important condition for obtaining products of consistently high quality and increasing production efficiency is the establishment of rational dosages of the formulation components in the preparation of the dough. Mathematical methods of planning of experiment are applied to study the interaction of the major technological factors influencing the process of preparation and the quality of bread products. The optimization of parameters of preparation of dough for ahloridny bread was performed using experimental and statistical methods. As a result of the performed experiment a mathematical model in the form of regression equation which adequately describes the studied process has been developed. The statistical processing of experimental data has been performed according to Student, Kokhren and Fischer criteria (with the confidential probability of 0.95). The graphic interpretation of regression equation has allowed to determine previously the optimum area of factorial space in which the highest value of output parameter is reached – the specific volume of bread. Rational values of factors have been determined: the dosage of flour from bran of greenschish is 4.87%, the whey drink “Actual” is 24.86% when making bread from a mixture of wheat flour of 1st grade and whole wheat seed in a ratio of 50:50. Their choice has been validated by a series of parallel experiments which has shown sufficient convergence of results with the average square error of no more than 0.67%. On the basis of the obtained data a formulation and a way of production ahloridny bread “Symphony”.

Keywords: : non-traditional types of raw materials, ahloridny bread, central composite rotatable uniform planning, optimization.

MODEL AND ALGORITHM THAT OPTIMIZE THE CHOICE OF A TRAINING AREA AT A MULTI-PURPOSE TRAINING

UDC 681.3

V.V. Menshikh, E.N. Sereda


The article deals with the problem of how to optimize the distribution of students according to the areas of training in the groups of multi-purpose training. Training and retraining of professionals in fact presupposes facilitating the optimal individual educational trajectory for each specialist. There is a need to form groups of multi-purpose training since, on the one hand, certain training areas are unique and there is a lack of the pertinent categories of students, and on the other hand, related areas require similar training trajectories. It will contribute to saving resources of an educational institution and sometimes can increase the training efficacy. The training trajectories in such groups can overlap, which makes it possible to dynamically redirect students to subgroups that master different competences. When organizing a multi-purpose training the primary task is to choose the training area for each specialist, and the corresponding mathematical apparatus to optimize this task has not been studied sufficiently. This research carries out a mathematical approach to this problem. The article defines two stages of its solution: 1) assessing the perspectives of students to form competencies in accordance with the training areas; 2) finding an optimal way to distribute the trainees in the areas of training. The paper suggests an algorithm for solving the problem.

Keywords: : competence, the areas of training, training time, resource, optimization, a multi-purpose training.

THE DESIGN CALCULATION METHOD OF WIDEBAND INTERFERENCE LASER PLATES POLARIZERS

UDC 535.345.67

L.A. Gubanova, D.N. Perevozkin

The interference plates-polarizers are widely used in optical devices, in particular, they are used in electrooptical Q-switches of pulsed solid-state lasers. The standard all-quarter-wave construction of the interference layers of the polarizer plates is characterized by a narrow band of the working spectral range, which does not fully correspond to modern requirements. A method is proposed for calculating the practically feasible designs of broadband interference polarizer plates, based on the alignment of the thicknesses of the layers included in the non-quarter-wave structures, synthesized using widespread computer software for the calculation of interference optical coatings.

Keywords: optical interference polarizer, polarization contrast, porous multilayer interference coating, OptiLayer, optimization.

A. P. Preobrazhensky

This paper is devoted to consideration of the objectives related to the optimal choice of parameters controlled in the systems of electric power generation. We discuss the possibilities for the application of the main criterion for the case of multicriteria optimization of the process of electricity generation based on alternative sources. Refers to the need to focus on the Pareto set. Indicated that one of the solutions to a multicriteria problem can be a combination of goal programming, and narrowing the scope of trade-offs involving data, what is the relative importance of the criteria. The use of simplifications when there is a formation of Pareto-optimal solutions for specific processes of power generation based on alternative sources can be considered as an important task, to ensure that its consideration has been reduced and time costs to a reasonable level.

Keywords: optimization, renewable energy, multicriteria approach, function, method, algorithm, parameter.
