INFORMATION RECEIVING IN ONLINE TRAINING PROCESS MANAGEMENT BASED ON COMPLEX OPEN ENDED ASSIGNMENTS SCORING
Information gathering stage is one of the most important stages in management. The efficiency of management depends on received information. Information gathering methods depend on an object of management specificity. Testing results are the main information in training process management in training systems. Collected statistics of the testing results is the base for decision-making. A problem occurs when a training course contains tasks, implementation results of which cannot be checked by means of tests. Such tasks are complex open ended assignments. Different methods are used for scoring such tasks in learning management systems and massive open online course platforms. The methods are addressed in the paper. Method classes such as: methods implemented by standard tools of training systems (student self assessment, peer assessment, tutor or external expert manual assessment), methods implemented by extending the functional possibilities of training systems (situational assignment), methods implemented by external programs (special methods for specific domain) are described. Applicability of methods for information gathering in online training process management is identified. Reliable and complete information can be received only by using situational assignment and special methods for specific domain.

MATHEMATICAL MODELING OF THE TASK OF DETERMINING A SET OF CONTROL EVENTS USING A FUZZY METHOD OF ANALYSIS OF HIERARCHIES AND A METHOD BASED ON MEASURING LATENT VARIABLES
N.E. Krasova, N.A. Aleynikova
The article discusses the mathematical modeling of the problem of multi-criteria selection of control measures for the ongoing monitoring of performance using two methods: a method of fuzzy analysis of hierarchies and a method based on measuring latent variables (the Rush method). Both methods are expert methods. The advantage of using a fuzzy hierarchy analysis method is to describe the relative attribute values using fuzzy numbers instead of exact ones. Due to this, the expert gets the opportunity not only to assess the degree of preference of one object over another, but also to express his doubts, experience, intuition in this assessment. The main disadvantage of this approach is the complexity and complexity of the calculations. The advantages of the Rush method are in the simplicity of calculations, in the transition from the subjective assessments of experts to the objective ones, which possess the property of linearity. Within the framework of the constructed hierarchical model aimed at increasing the efficiency of the learning process, weights of different types of control measures are determined by these methods. In the future, the weights obtained can be used as parameters in the models for the formation of a set of control measures based on minimizing the difficulty of their implementation and maximizing their usefulness.

A CONCEPT OF ONLINE AUTOMATED TRAINING PROCESS MANAGEMENT IN IMPLEMENTING COMPLEX OPEN ENDED ASSIGNMENTS BASED ON THE USE OF ERROR BANK
Online learning is widely distributed. This type of learning can take place at specific university by means of learning management system or by means of massive open online course platforms independently of universities. Management problems arise in existing training systems if a training course contains assignments, result of implementation of which cannot be checked by standard tests. This relates to knowledge and skills assimilation management and to training process management. A class of assignments which causes difficulties in online learning and training management (complex open ended assignments) is described in the paper. A concept of online automated training process management based on the use of error bank in implementing such tasks is suggested. The concept is based on system and process management approach, classification of errors made by students during complex open ended assignment implementation, the principle of management subsidiarity, automated training. Using of a specific software package, which contains software modules for automated scoring, information collection and processing, decision making, on a par with learning management systems with functionality of the automated training is proposed to increase the effectiveness of management.
Keywords: online learning, automated training, error classification, process management, training process management, complex open ended assignment.
METHODOLOGICAL AND DIDACTIC FEATURES OF INFORMATION TECHNOLOGIES USAGE IN THE PROCESS OF MATHEMATICAL EDUCATION OF FUTURE ENGINEERS
L.S. Sagatelova, E.G. Shvedov
Methodological and didactic features of the usage of information technologies in the process of mathematical education of future engineers are revealed in the article. The didactic aspect of the implementation of mathematical education with the use of information technology is based on a careful selection of the content of training in accordance with the Federal State Educational Standards of Higher Education; methodical — involves the choice of effective forms of conducting classes using the capabilities of information technology, the organization of independent work (classroom and non-auditory). We define the concept of “information technology training”. Examples of actively used means of information technologies are given. This allows us to improve continuously the content and the teaching methods, and to increase the effectiveness. The process of mathematical education is based on the orientation on the requirements of the future profession, taking into account the individual character features of students. Strengthening the applied component is carried out by introducing special mathematical courses, developed in conjunction with the profiling departments, as well as solving professionally-oriented tasks using such software as Excel, Mathcad, Maplе, Mathematica. An example of a professionally-oriented task is provided in the article. The stages of the students’ activities organized by the teacher to solve it are described in details.

ADAPTIVE AUTOMATED SYSTEM AS A TRAINING DIFFERENTIATION MEANS IN THE INFORMATION TECHNOLOGY SPECIALISTS EDUCATION PROCESS
UDC 004.9, 37.04
N.V. Datsenko, S.A. Gorbatenko, V.V. Gorbatenko
One of the most effective ways to implement a differentiated approach in the information technology (IT) specialists training which consists in the adaptive automated learning system use is proposed in the article. The system will allow to store a large amount of educational information, to modify it if necessary, to adapt it to different categories of users in accordance with their level of initial training, to check the formation of competencies and analysis of mistakes made by students in the control testing process. The system dataware includes a relational database (DB), which contains theoretical information of the discipline, exercises and control tasks on all topics, adapted to different categories of students, as well as a table in which all erroneous answers of users are entered during the control testing for further analysis. The software contains the users automatic classification module which is based on the cluster analysis method and allows at the input control stage to form four groups of students depending on the level of residual knowledge obtained in the previous disciplines study, corresponding to the marks as “excellent”, “good”, “satisfactory” and “unsatisfactory”, in order to differentiate the educational material. The training program module is designed to solve the problems of new knowledge acquiring by students of different groups, using the theoretical knowledge obtained in the practical tasks implementation and checking the competence formation level. In the event that the level has not reached the baseline, the error analysis module allows to determine which discipline subjects have caused the greatest difficulties for the student to re-study.

AUTOMATION OF PERSONALIZED FEEDBACK IN THE PROGRAMMING STUDIES COURSES
The use of automatic feedback can significantly increase the success of beginners in programming, especially for those who have to study inside a large group, and the teacher’s time is limited. The article proposes an approach to the creation of automatic feedback based on previous solutions. The approach is to form a solution space of programs – weighted graph. The nodes in the graph are the program code; the edge weight is the number of changes and actions that need to be performed in order to go from one state to another. To reduce the number of unique solutions, the source code is normalized using a number of transformations and the construction of an abstract syntax tree. Feedback is a hint of the next step, which can be generated after a new solution is added to an existing graph and the path leading to a more correct state is identified. Thus, with the help of feedback you can reach the right decision. Using the solution space also allows you to find out which solutions are most common, which errors occur and which ways they can be corrected students prefer. Since this approach is based solely on data, the teacher does not need significant interaction with, which makes it scalable and adaptable.

MANAGEMENT OF FUNDS ALLOCATION OF AN EDUCATIONAL
The article presents the expert optimization approach to improving the efficiency of funds allocation management in an educational organization, which is a combination of intelligent technologies, analytical and numerical methods. It is suggested that managerial decisions should be focused on the objectives of funds allocation and development strategy of the educational organization. Achievement of these goals is provided by the use of expert-optimization approach in the tasks of funds allocation between the budgeting objects. The functional funds allocation among school business processes is carried out with the use of an expert knowledge model of transforming the results of a SWOT analysis of building membership functions of vague relationships. The budget allocation of income and expenses between the centers of financial reporting is implemented on the basis of expert assessment with the use of linguistic variables and a formalized model of multi-alternative optimization. For the allocation of the investment budget among the educational organization development projects, a preliminary expert analysis of management accounting mechanisms with a transition to the multi-alternative optimization task is used.
Keywords: :management, funds allocation, expert-optimization approach, linguistic variables, management accounting, multi-alternative optimization.
MODEL OF SYSTEM DYNAMICS OF PROCESS OF TRAINING
A.V. Ganicheva, A.V. Ganichev
The relevance of this work is caused by importance of account in educational process of personal qualities of trainees. Importance of the solution of this problem is defined by the fact that competence-based approach assumes formation of future workers capable independently to work in various situations, to have an impact on others. When training in non-uniform educational collectives (groups) it is possible to allocate subgroups of pupils by different criteria: to abilities, progress, discipline, etc. Subgroups of trainees have an impact at each other. Force of this influence depends on the number of subgroups, of coefficients of influence and time of impact. As a result of mutual influence, it is possible of the trainee to move from one group to another. The article uses the method of mathematical modeling to analyze and account for the dynamic interaction of pupils in the team. The model is based on the system of differential equations of J. Forrester. The analytical solution of a system for a standard case in educational process – existence of three types of subgroups of trainees is received. A numerical example is given to illustrate the results. Results of its decision are presented graphically. Important special cases of the General system of differential equations (setting of relations between the coefficients of influence) are considered. The developed mathematical model will improve the quality of the educational process.
Keywords: : group of trainees, model, coefficients of influence, system of differential equations, solution.

S.S. Vasilyev, A.A. Kharitonov, D.M. Korobkin, S.A. Fomenkov
The task of automation of synthesis of innovative solutions in the field of technical systems and technologies is one of the most priority problems of science. The authors propose to automate the most important, initial stages of the design of new technical systems and technologies on the basis of updated knowledge bases obtained from the world patent database, including the Rospatent patent database. According to the method of morphological analysis and synthesis, it is assumed that the main structural features (functions of technical objects) are extracted from some technical solution (patent), on the basis of which alternative options are sought. All these features are reduced to a morphological table, combined, which gives a lot of new solutions. The paper describes the developing a software for extracting the technical functions descriptions from Russian patents. The grammar of the presentation of technical functions descriptions according to the model “Action-Object-Condition” in the Russian-language patents was formed; algorithms for the initial processing of the patent database, the extraction of technical functions through the analysis of dependency trees, the formation of the morphological table was developed. The software consisting of a module of patent database processing; a module of text segmentation of the patent formula; a module of semantic text analysis; a module of extracting descriptions of technical functions; a module of presenting the results of patent database processing, was tested to solve practical problems.

GRAMMATICAL APPROACH TO THE DESCRIPTION AND ANALYSIS OF THE GOALS OF THE EDUCATIONAL PROCESS
A. V. Ganicheva, A. V. Ganichev
The relevance of the study is due to the complexity and importance of the problem of definition and description of goals in the educational process. The importance of solving this problem is determined by the fact that without the correct formulation and coordination of the goals of the educational organization it is impossible to operate any educational institution. Currently implemented in the education system competence approach puts forward new, increased requirements for goal-setting, including the ultimate effectiveness of the goals. To describe the hierarchical structure of the goals it is necessary to formalize them (to build a mathematical model of the goals). Currently, there is no universal method for developing such models. The article describes the method of description and analysis of the educational process using the mathematical apparatus of formal KS-grammars. As an example of application of the developed method the grammar for the description of the purposes of departments within interdisciplinary training is constructed. Shows an example of the grammar chain for the hive dependencies. The tree of syntactic subordination is constructed. The materials of the article are of practical value, as they can be used not only in the educational process and other areas of the social sphere (culture, health, etc.), but also in the systems of industrial and economic sphere.
