MATHEMATICAL, SOFTWARE AND HARDWARE SUPPORT OF THE CONCEPTUAL MODEL OF THE INFORMATION SYSTEM OF PRECISION AGRICULTURE

This study analyzes the current situation of application of precision farming technologies and solutions by agricultural enterprises of the Republic of Kazakhstan. The main players and used solutions have been identified. The statistics of application, as well as the potential of use is examined. Within the framework of the analysis of the applied solutions the advantages and disadvantages of competitors in the market were determined. It was defined that the applied systems provide the possibility of remote management, but EGISTIC is more focused on the management of all processes of the farm, including the warehouse, while John Deere is focused on the management and analytics of agricultural machinery. EGISTIC offers features for warehousing and inventory planning, something not found in the base version of John Deere Operations Center. John Deere focuses on data sharing which can be important for large farms or groups of farmers. EGISTIC makes extensive use of satellite imagery to analyze field conditions which can be a great asset for identifying problem areas and planning interventions. Depending on the specific needs and priorities of an agribusiness, one system may be preferable to another. If machinery management is the main focus, John Deere might be the best choice. If in-depth analysis of field conditions and inventory control is important, EGISTIC may be more appropriate. By analyzing, the directions for research are highlighted. A conceptual model of information system for precision farming is developed. Hardware for realization of the conceptual model is possible on the basis of universal programmable logic controller of modular architecture being developed. Within the limits of the given research the conceptual model of the universal programmable logic controller of modular architecture and the structural model of the software of the universal programmable logic controller of modular architecture have been developed. The interaction with the conceptual adaptive model of information and communication system is also considered. This paper analyzes the key principles and functions of both the universal programmable logic controller and the information and communication system, as well as their possible integration within a single concept.

FORMALIZATION CODING METHODS OF INFORMATION UNDER TOROIDAL COORDINATE SYSTEMS

Contents. Coding and processing large information content actualizes the problem of formalization of interdependence between information parameters of vector data coding systems on a single mathematical platform. Objective. The formalization of relationships between information parameters of vector data coding systems in the optimized basis of toroidal coordinate systems with the achievement of a favorable compromise between contradictory goals. Method. The method involves the establishing harmonious mutual penetration of symmetry and asymmetry as the remarkable property of real space, which allows use decoded information for forming the mathematical principle relating to the optimal placement of structural elements in spatially or temporally distributed systems, using novel designs based on the concept of Ideal Ring Bundles (IRB)s. IRBs are cyclic sequences of positive integers which dividing a symmetric sphere about center of the symmetry. The sums of connected sub-sequences of an IRB enumerate the set of partitions of a sphere exactly R times. Two-and multidimensional IRBs, namely the “Glory to Ukraine Stars”, are sets of t-dimensional vectors, each of them as well as all modular sums of them enumerate the set node points grid of toroid coordinate system with the corresponding sizes and dimensionality exactly R times. Moreover, we require each indexed vector data “category-attribute” mutually uniquely corresponds to the point with the eponymous set of the coordinate system. Besides, a combination of binary code with vector weight discharges of the database is allowed, and the set of all values of indexed vector data sets are the same that a set of numerical values. The underlying mathematical principle relates to the optimal placement of structural elements in spatially and/or temporally distributed systems, using novel designs based on tdimensional “star” combinatorial configurations, including the appropriate algebraic theory of cyclic groups, number theory, modular arithmetic, and IRB geometric transformations. Results. The relationship of vector code information parameters (capacity, code size, dimensionality, number of encodingvectors) with geometric parameters of the coordinate system (dimension, dimensionality, and grid sizes), and vector data characteristic (number of attributes and number of categories, entity-attribute-value size list) have been formalized. The formula system is derived as a functional dependency between the above parameters, which allows achieving a favorable compromise between the contradictory goals (for example, the performance and reliability of the coding method). Theorem with corresponding corollaries about the maximum vector code size of conversion methods for t-dimensional indexed data sets “category-attribute” proved. Theoretically, the existence of an infinitely large number of minimized basis, which give rise to numerous varieties of multidimensional “star” coordinate systems, which can find practical application in modern and future multidimensional information technologies, substantiated. Conclusions. The formalization provides, essentially, a new conceptual model of information systems for optimal coding and processing of big vector data, using novel design based on the remarkable properties and structural perfection of the “Glory to Ukraine Stars” combinatorial configurations. Moreover, the optimization has been embedded in the underlying combinatorial models. The favorable qualities of the combinatorial structures can be applied to vector data coded design of multidimensional signals, signal compression and reconstruction for communications and radar, and other areas to which the GUS-model can be useful. There are many opportunities to apply them to numerous branches of sciences and advanced systems engineering, including information technologies under the toroidal coordinate systems. A perfection, harmony and beauty exists not only in the abstract models but in the real world also.

ON POSSIBLE FUNCTIONAL COMPONENTS OF THE INFORMATION SYSTEM OF ARMS AND MILITARY EQUIPMENT TESTING OF THE ARMED FORCES OF UKRAINE

Today, the problem of ensuring the effectiveness of the system of testing weapons and military equipment remains relevant. According to the existing national legislation and the accepted standards, separate specialized institutions are involved in the testing of samples of armaments and military equipment. One of the methods of improving the efficiency of test centers and institutions is the automation of all processes that accompany the testing of samples of weapons, military equipment and special equipment.
 The article highlights the approaches to the design and practical implementation of the information system to support the testing of weapons and military equipment. Its possible functional composition is considered. It is assumed that the information system should automate all processes in the test facility that are somehow related to the tests.Based on the analysis of existing guidance documents and scientific and technical information sources, the composition of the main functional components of the information system of test support is proposed. The necessity of introducing a management component into the information system for the implementation of a targeted approach to the management of a testing facility is substantiated. Reclassification of tasks of information databases on stages of carrying out tests is done.
 Based on the generalized scheme of testing the conceptual model of information system of support of tests is offered.The approximate composition of individual software modules and the content of databases are given.The expediency of using a spiral model of software design for the development of a comprehensive full-featured information system for test support is substantiated.
 It is expected that the automation of planning, conducting and other processes that accompany the tests can significantly affect the overall efficiency of the organization and conduct of tests, ensure the proper quality of the results and help reduce time losses for testing.

Ангстремтехнологія авіаційної кібербезпеки

Анотація. В авіаційній галузі проблема прийняття управлінських рішень, що повністю усуває авіаційні аварії та рятує людські життя, є особливо гострою. У колишні часи ця проблема ніколи не досліджувалася конструктивно. За кордоном лише вісім вчених (К. Ерроу, Г. Сімонс, П. Лукас, Г. Кляйнер, Б. Канапльов, Г. Бахарєв, А. Іншаков і Т. Любимова), які займаються наноекономічними підходами та методами, використовуваними для вирішення проблеми розвитку інтелектуального капіталу в цілому та контролю знань зокрема. Але в області авіації й управління авіакомпаніями немає досліджень і публікацій ні в Україні, ні в закордонних країнах. Отже, автори ввели нові економіко-математичні концепції та визначили роль 3D-моделювання в ангстремтехнологіях авіапідприємств з точки зору погляду на інформаційну безпеку та кібербезпеку. Успішні менеджери намагаються «запрограмувати» якомога більше управлінських рішень для підвищення ефективності управління інформаційною безпекою та кібербезпекою. Автори виконали 3D-моделювання інформаційної безпеки та прийняття рішень з кібербезпеки у питаннях повітряного простору, які можна розглядати як невелику версію моделювання з гнучкою шкалою часу (FTS) у використанні ангстремтехнології управління. У дослідженні визначені засоби економіко-математичного моделювання управлінської інформаційної безпеки та створення кібербезпеки в задачах авіаційної промисловості, що складаються з програмних модулів, які використовуються для задоволення потреб проектувальників повітряного простору. Інструменти моделювання зазвичай не використовують вигнуті сегменти. Точний опис маршрутів прибуття та відправлення, визначених вигнутими сегментами, може бути визначено з використанням апроксимованих лінійних сегментів моделі. Цей же метод пропонується використовувати для опису резервних областей. Розроблено концептуальну модель інформаційної системи ангстремтехнології авіапідприємств, отримано вплив на прийняття рішень щодо забезпечення інформаційної безпеки та ефективності кібербезпеки авіапідприємств. У цій статті висвітлюються результати використання нейронної мережі для управління людським мисленням. Зроблені висновки свідчать про те, що ангстремтехнологічна модель є зручним інструментом керівника авіапідприємства та потужним аналітичним інструментом у цілому. Завдяки їх використанню можна не тільки зберігати й інтегрувати дані, але і відображати процес роботи об'єктів на 3D-моделях.

The measurement of perceived ontological deficiencies of conceptual modeling grammars

Over recent years, many scholars have studied the conceptual modeling of information systems based on a theory of ontological expressiveness. This theory offers four constructs that inform properties of modeling grammars in the form of ontological deficiencies, and their implications for development and use of conceptual modeling in IS practice. In this paper we report on the development of a valid and reliable instrument for measuring the perceptions that individuals have of the ontological deficiencies of conceptual modeling grammars. We describe a multi-stage approach for instrument development that incorporates feedback from expert and user panels. We also report on a field test of the instrument with 590 modeling practitioners. We further study how different levels of modeling experience influence user perceptions of ontological deficiencies of modeling grammars. We provide implications for practice and future research.

Estudo exploratório sobre ontologias aplicadas a modelos de sistemas de informação: perspectivas de pesquisa em Ciência da Informação

Ontologies have become the subject of ever increasing interest in several areas. Beyond its philosophical roots, it has been used broadly in research fields related to systems development. Within the scope of automated information systems, the use of ontology has two main goals: it can be used as a component of a system or as a reference. This reference is a kind of comparison standard employed to evaluate the capacity of the model underpinning the system to represent the world. The present article explores the latter application, discussing the usefulness of ontologies in conceptual modeling processes. After the contextualization of the research and of some problems related to conceptual modeling of information systems, we present ontologies used as references, in addition to related initiatives. We discuss the relevance of this subject with regards to Information Science, interfaces and the potential for interdisciplinary research. We conclude by highlighting the importance of the Information Science disciplines in addressing issues related to deficient modeling and to lack of systems integration. We hope to contribute to the interchange between different areas, as well as suggest new perspectives for the work of Information Science professionals.

Information System's Roles and Responsibilities

The concepts of an information system's roles and responsib ilities can play a significant role in the outset of the information systems dev elopment (ISD) process. This aspect has not been the subject of much debate and attention in ISD. In this paper an attempt is made to outline a conceptual model of information systems' roles and responsibilities. This conceptual model is an initial step towards exploration of the relationship between the concepts of in formation systems' roles and responsibilities.

Determining object interaction in object-oriented deductive conceptual models

We present the main components of an object-oriented deductive approach to conceptual modelling of information systems. This approach does not model object interaction explicitly. However, interaction among objects can be derived by means of a formal procedure that we outline. Based on our results, we discuss whether explicit object interaction is a desirable feature of conceptual models.

Staffing, planning, and control of information systems in charitable nonprofit organizations

Staffing, planning, and management control of information systems in the private not-for-profit (or nonprofit) sector are studied, based on a survey of symphony organizations in the United States and Canada. A conceptual model of information systems for charitable nonprofits is presented which emphasizes staffing, planning, and control. Empirical results for symphony orchestras reveal low IS funding, weaknesses in IS staffing, heavy dependence on outside expertise, low levels of IS training, inadequate IS planning and control, and moderate IS satisfaction. The model is tested empirically and found to be largely valid. A model modification is suggested in assessing the factor of IS satisfaction.
