The article presents a computer program, which define automobile transport demand for the transport service of harvesters in the grain harvesting process. The program has a simple and intuitive user interface, a flexible setting system. It allows to change the source data for needs everything agricultural companies. It doesn’t require an installation and it can function in everything operation systems, which is fitted for Microsoft office applications acting. It doesn’t require a special studying or deep knowing in a mathematical statistic for using. Everyone specialist can use the program in an agricultural enterprise. The program considers distribution laws of stochastic parts of the grain harvesting process. These process features are important to consider due to using of determination values give very rough results. If there are mistakes in the structure design of the harvesting-transport complex then there are nonproductive machines downtimes or the harvest losing. Using the program gives better organization of the transport service in the grain harvesting process, and it can give the economical effect. It is especially important in modern competitive conditions at the worldwide market of agricultural products and also at the interior market with consideration of external economical sanctions and with consideration of the declared import replacement course. The successful work of agricultural enterprises defines the country's food security and it turns down the oil dependency of the Russian economy

The modern state of the territorial road system in South Russia is analyzed in the article. It considers some districts of the Rostov region, the Krasnodar region and the Stavropol region, which have roads with inappropriate technical parameters, and some districts, which don’t have paved roads for transport connection localities. Road service is a function of road construction companies. Numbers of vehicles in companies participating in the technological process of prepare, delivery and asphalting don’t match the amount of work. Therefore, the article analyzes the transport structure of road construction companies in the most problem districts of the Krasnodar region, the Stavropol region and the Rostov region. On basis of data on providing the companies with vehicles and length of roads the closeness of the relationship is defined which is estimated with the correlation coefficient. The road construction company with the best coordination of the delivery power, the number of vehicles for preparation, transportation and asphalting, and the length of roads is identified. The optimal coefficient of providing every hundred kilometers with rolling stock for service is defined as the analysis result

The variants of the procedure for optimizing of de-livery of goods with motor transport in a city with the use of network and linear models is shown on the example of the delivery of household chemical goods

The variants of fastening of harvest-transport groups to fields and their influence on the reduction of need in automobiles are observed in this article, on the example of two farms

The method of optimization of the process of delivery of the mineral fertilizers to agricultural consumers are given on an example of farms of Egorlyk district of the Rostov region

The article presents a computer program for estimation of economic efficiency of investments in car service companies. Estimation of economic efficiency of investments is the most important problem on the development stage of creating the project, modernization and development of production, including car service. Car service is one of the most intensive developing sectors of Russian economics due to increasing amount of vehicles, and therefore, it is a significant part of works and services that compose the gross domestic product. At the same time, investments in companies of car service are risky, because wrong prognosis of economic efficiency can lead to unprofitability of the company or inadmissible time of investments payback. For reducing risks of incorrect investing we have designed a special computer program for estimation of economic efficiency of investments in companies of car service. It can determine different efficiency indicators and take into consideration all the different payments and required investments. The results of the program operation are outputting in forms of the informative table and the plot of the really project estimating. Visual Basic for implementation in MS Excel is the language of realization program, because it doesn’t require additional license

The example of the delivery process of asphalt mix-tures for the roads repairing is shown in this article using the special computer program
