Появление судов с колесным движительно-рулевым комплексом, обладающих рядом специфических конструктивных и динамических особенностей, потребовало новых подходов к созданию алгоритмической и аппаратной базы для создания систем управления, обеспечивающих безопасную и эффективную эксплуатацию судов этого типа. Представлена структура судовой электростанции, ее особенности, связанные с обеспечением работы электропривода гребных колес и выполнения функций энергосбережения и резервирования. Приведены этапы развития комплексной системы контроля и управления для судов с колесным движительно-рулевым комплексом. Рассмотрена структура распределенной системы и ее аппаратная база, дающая широкие возможности автоматизации как отдельных подсистем и судовых технологических процессов, так и судна в целом. Приведены отдельные алгоритмы управления, реализованные в системе. Система позволяет модернизировать алгоритмическое обеспечение в процессе эксплуатации судна по мере возникновения ситуаций, требующих его коррекции. Обновление программных модулей не требует изменения структуры системы или аппаратной части системы. The appearance of ships with wheeled propulsion/steering system with a number of specific structural and dynamic features required new approaches to creation of algorithmic and hardware base for creation of control systems ensuring safe and efficient operation of this type of ships. The structure of the ship's power plant, its features related to ensuring the operation of the electric drive of the propeller wheels and performing the functions of energy saving and redundancy are presented. The stages of development of integrated control and management system for ships with wheeled propulsion/steering system are given in the article. The distribution system structure and its hardware base are considered. The hardware base gives ample opportunities for automation both individual subsystems and the ship technological processes, and the ship as a whole. Some control algorithms implemented in the system are described. The system makes it possible to upgrade algorithmic support during the operation of the vessel as situations requiring its adjustment arise. Updating software modules does not require changing the system structure or the system hardware.

The introduction of information and digital technologies that support and support all technological processes in the field is an urgent need for the development and implementation of such technology. An organisationally complex and financially intensive project is necessary because of the wide variety of economic entities that differ in the size of production, forms of ownership and socio-economic conditions of production. Automated information control system for mobile units agricultural enterprise provides those-Niko-economic performance, optimum capacity utilization through the use of timely and reliable information on technology. Machine and tractor aggregates are appertained as control objects with variable structure, which is explained by possibility of the system formation from tractor or field machines mobile units with various purposes: tillable, cultivatable, sowing, harvesting and etc. This MTA feature was determined creation of digital control systems of two groups of automatic control and management of the basic energy and operational parameters: tractors, machines and vehicles as part of MTA. To the first group are appertained the automatic control system of tractor motor component loading, motion speed, frictional sliding. To the second group – automatic regulation system of operating depth, seed rate, treatment of liquid combined fertilizers and crop protection agents, filling and driving of various MTA. Novelty of researches consists in methodology of the organization of the centralized control and management of various technological processes at carrying out field works.

The article addresses the problem of redistribution of warehouse resources when working in a virtual organization or when changing the logistics structure of the enterprise. A two-stage model of providing warehouse resources to a common access to participants of a virtual en-terprise is considered. An automated system for managing redistribution of resources for the stage of disconnecting from a virtual enterprise or when closing your own warehouses was developed. A description of the control object - a distributed warehouse system of an industrial enterprise specializing in the production of sheet metal. A formalized description of the technological process for the production of cold-rolled steel, including the stages of stockpiling, has been developed. The task of managing the distribution of resources is posed, the functional structure of the software complex is designed. Information, mathematical and algorithmic support for solving the problem of redistributing resources is presented. The architecture of information support includes a database containing regulatory and reference information and document management of the enterprise. The database information is used by the algorithmic support of four functional modules: management of normative and reference information, management of receipts and sales, management of warehouse movements, management of multi-turn packaging. The result of the work is presented by the system of dynamic redistribution of warehouse resources and implemented on the 1C: Enterprise platform, which allows solving the problems of the operational movement of material resources between the enterprise’s warehouses, also under the conditions of the virtual enterprise functioning. Absolute and relative distribution criteria are formed. The first group includes absolute criteria: volume, quantity, amount, weight. The second group consists of relative distribution criteria: quantity/volume, amount/volume, weight/volume. Testing the system using the example of criteria from each group showed the operability of all types of support using the example of a warehouse complex of an enterprise manufacturing metal rolling. Flexible customizable system structure allows you to expand the application of the proposed algorithmic support to other types of resources.
