The railroad warehouse has most important role in the delivery process of fertilizers to agricultural consumers. It acts as logistics intermediaries. The analysis of material flows has been done on the example of a typical provider of mineral fertilizers in the South of the Rostov region (CJSC «Zernogradagrohimservis») for the last 6 years. Income values and implementation values are varied during the year synchronously for all fertilizers types with the exception of a few months at the beginning and the end of the year. During most of the year the enterprise operates as a negotiable warehouse. In January-February and October-December ammonium nitrate accumulates as a seasonal inventory for the spring peak of implementation, in the rest of the year its reserves are insurance. Stocks of other fertilizers types are insurance stocks for most of the year, in May-July occurs a slight accumulation of their seasonal stocks. A significant portion of mineral fertilizers (especially ammonium nitrate) is delivered for small enterprises and individual farms by cars of this provider. According to the supply contracts, a one-car-run is performed for the vast majority of customers. Routes of delivery of fertilizers are either radial or pendulum (with reverse idle mileage). Therefore, the optimization of the delivery of fertilizers does not seem possible by methods such as obtaining the shortest route network, consolidation of suppliers for consumers, etc.

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

There is a presentation of the operation analysis of the harvesting-transportation complex with using the system of collecting and processing information and there is estimation of its impact on the complex productiveness

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 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

Currently, for producers of mineral fertilizers one of the main tasks is the process of creating a supply chain of mineral fertilizers delivery to agricultural consumers, running on a «Just-in-time» way. The effective operation of such a supply chain has to be influenced by many factors, including: the technology of agricultural production, seasonality of agricultural work, the structure of the distribution channel of mineral fertilizers, the geographical features of consumers, the availability of appropriate infrastructure, etc. Critical elements of the infrastructure are warehouses and equipment for storage of mineral fertilizers, as well as the road network. For example, farms in the Rostov region were analyzed for the infrastructure necessary for the successful supply of mineral fertilizer agricultural consumers. It was found that the capacity of warehouses and facilities for the storage of mineral fertilizers and distribution of cultivated areas between agricultural enterprises of different size are diametrically opposed. The process of delivery of mineral fertilizers need to be developed taking into account the shortage or complete lack of storage capacity for their storage, especially for small enterprises. The existing road network, with paved allows us to deliver of mineral fertilizers virtually all consumers by road transport. This dictates the feasibility of delivery of mineral fertilizers to consumers by road transport in soft containers (Big Bags), allowing the storage in the open air

The article explains the importance of the transport process when performing repair jobs of asphalt roads. The scheme of the technological process was drawn up; job steps were identified, while the latter may be characterized by non-productive downtime of transport as well as that one of technological machines. We have analyzed the following steps of the flowchart of the road concrete mix transportation: the preparation of the road concrete mix for transportation, loading, transportation, unloading, laying and packing. The transportation of goods starts at the working site of their production and ends at the site of their consumption. The transportation process is a multistep and multioperational process having the greater diversity of technological, operational and economic operations, which must be correctly organized. It is extremely important to deliver the road concrete mix of coating plant (OP) just in time, while avoiding the unproductive idle standing of the equipment, the deterioration of the mixture, as well as performing the job steps at minimum transportation cost savings. The successful combining of the steps of the concept organization of the road concrete mix transportation (coating plant, asphalt laying step, transportation step) will improve the performance and will provide the reduction of the job cost. One must perform the coordination of job steps on different road sections using information technologies and communication facility

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