PRECONDITIONS AND FEATURES OF DEVELOPMENT OF “MICRO-CLIMATE” MANAGEMENT INFORMATION SYSTEM
DescriptionThe article investigates the experience of implementing automated control systems, which indicates that at the system design phase, it is difficult to choose a single criterion of control. Therefore, in the control system it should be possible to quickly set the criterion during operation, and methods of assignment should clearly reflect the agronomic, economic and technical requirements for the system. Thus, modern control system should allow to define not only one of the above control criteria, or a combination, but any other arising in the production process, providing agronomist-technologist opportunities in choosing a method of maintaining temperature and humidity conditions in the greenhouse. Greenhouse is a fastpaced environment and the state largely depends on the intensity of sunlight, humidity, direction and wind speed, the number of fertilized soil and its humidity. Competent and correct management of these parameters is a complex task and involves certain costs, but in the end allows you to benefit many times greater than the costs. The developed system called "Microclimate" will have a positive effect on any hosted sites, as it allows to increase energy efficiency and reduce fuel costs for heating greenhouses, electricity, water

PROBLEMS AND PROSPECTS OF TRANSPORT TECHNOLOGY FOR VILLAGES
DescriptionModern condition agricultural transport (a significant part of it about 70%) is characterized by a strong deterioration of the rolling stock, the unsatisfactory state of the production base. More than 30% of vehicles operated outside the normative service life, the rest approaching to that state. In general, the provision of agrarian and industrial complex with agricultural vehicles is way below agrotechnical requirements. In the long term, farm machine engineering should focus on indicators of the technical level achieved by best samples of foreign agricultural machinery. Priority development is likely to receive the development of innovative technologies that provide a significant increase in productivity, efficiency and resource conservation in agriculture. To address the shortcomings of transport services agrarian and industrial complex we should improve transport technology with the use of transport logistics, expand and update the existing vehicle fleet, but due to the low solvency of agricultural companies and high prices for of automotive engineering, the problem of providing agricultural vehicles becomes most acute. Thus, the creation of new science-based solutions in technology and engineering for transportation farm produce in terms of Russia's AIC is the actual scientific and technical task that contributes significantly to the development of the country, as well as enhances the enjoyment of breakeven, competitive manufacturing

MODEL OF MULTIVARIATE FUZZY TIME SERIES FORECASTING OF ENERGY LOSSES
DescriptionNowadays the high level of electricity losses is one of the most important issues of the energy industry in the Russian Federation recognized at the state level. According to many sources, one of the activities that contribute to reduce energy losses, is their planning, an important component of which is the prediction of electricity losses on the basis of retrospective information. The highest percentage of technical losses of electricity is accounted for distribution network with a voltage range 0,4-35 kV. In this regard, the most productive activity is forecast construction namely of this component of power losses. According to some features of the regarded value (electricity losses) the most effective activity for its forecasting is using methods with artificial intelligence elements. One of these methods, having a number of important advantages, is forecasting fuzzy time series. This technique is widely consecrated in foreign publications, but did not find sufficient popularity in our country. This article analyzes the existing models of forecasting fuzzy time series on the basis of which proposals for their improvement and adaptation in order to predict the loss of electricity are made; designed model of multivariate fuzzy time series forecasting of energy losses is given

Description
The development of agricultural production inevitably entails an increasing volume of traffic and a turnover of goods. Therefore, the issues of increasing transport efficiency, reducing the price of transportations and improving productivity acquire great importance. In most cases, supersize dump trucks used for the transport of agricultural production have much more than 6 tons axle load. Thus, these cars need to have roads with improved surface to each field, which undoubtedly is a significant drawback. Because of the extra movements of harvester dump trucks on the turning strip at the end of the field, it increases expenses of damage and loss of crops and the arrival of heavy machinery in the field leading to soil compaction, that in the end affects the future crop. Transportation of agricultural commodities is most effective when the car arrives directly to the harvester machinery. Such vehicles must have sufficient abilities and capacity of the body comparable with the volume of a combine hopper and has no significant impact on soil sealing. With this method, harvesters do not make extra movements and are not idle. Basic requirements for vehicles used in the harvesting potatoes, are in a more productive use due to increasing the capacity and reducing downtime when loading or unloading and minimizing the level of damage to other tubers. For the transportation of agricultural products there is a different transport technology, which either do not fully meets the requirements of transportation of highly fragile product, or has a significant cost. Therefore, we require a specially equipped vehicle bodies, with a competitive ability in the range acceptable to the Russian Federation. As one of the innovative developments, this article proposes a tipper body of the vehicle for transportation of highly fragile agricultural products. The proposed design solution for the tipper ensures a uniform unloading of transported products from the vehicle body and prevents arching issues
