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.

In the modern world, with the development of economic relations, the need for optimal management of an agro-industrial enterprise is of prime importance. In order to achieve the goals set, to systematize ap-proaches to assessing the financial condition of the organization and to increase the effectiveness of risk management, the company needs to implement internal audit. The purpose of this article is to study and determine the development, the essence of internal audit and the need for its application in practice in agri-cultural enterprises, as well as to establish the feasibility of using internal audit in the management system to achieve goals. The study examined the latest work of leading specialists in the field of internal audit (R. P. Bulyga, I. S. Egorov, Zh. A. Kevorkova, M. V. Melnik, A. D. Sheremet, etc.), its nature was determined. and a place in the management of the organization. The object of the research work is internal audit in agro-industrial enterprises. The subject of the research is the definition of the main functions of internal audit, its role and place in the financial control and management system of the company.

WINSmartEV is a software based plug-in electric vehicle (PEV) monitoring, control, and management system. It not only incorporates intelligence at every level so that charge scheduling can avoid grid bottlenecks, but it also multiplies the number of PEVs that can be plugged into a single circuit. This paper proposes, designs, and executes many upgrades to WINSmartEV. These upgrades include new hardware that makes the level 1 and level 2 chargers faster, more robust, and more scalable. It includes algorithms that provide a more optimal charge scheduling for the level 2 (EVSE) and an enhanced vehicle monitoring/identification module (VMM) system that can automatically identify PEVs and authorize charging.
