OPTIMAL PARAMETERS OF TECHNOLOGICAL LINE FOR LOADING TOBACCO LEAVES INTO CONTAINERS
DescriptionThe article presents the research results on parameters optimization of technological line for loading tobacco leaves into containers. The aim of the research was decreasing labor expenses on preparing tobacco for artificial curing. This was achieved by line modernization utilized for loading tobacco leaves into containers. We have also developed working parts of technological line for automatic loading of tobacco leaves into containers. Researches on weight studying of tobacco leaves of 3 sorts zoned in the Krasnodar region have been carried out. Dispersion analysis has not revealed weight differences between sorts, therefore, further researches can be carried for one sort. Optimization of working part for loading tobacco leaves into containers was carried by analysis of regression equation obtained by bifactorial experiment. Irregularity of leaf position was taken as optimization criterion. It has been discovered that optimal regimes: transporter belt speed v=2,8m/s, number of transporter’s double movements n=19 min-1 can be used for uniform container loading by leaves. Researches on studying line capacity on leaves position irregularity revealed that maximal uniformity obtained when line capacity is 260 kg/h

OPTIMIZATION OF CONGESTION OF ROAD NETWORKS
DescriptionDefinition of the directions of development of transport system of the city is to ensure objectively justified needs for movement of goods and people on the territory of the city. Transport planning of the city is in direct connection with the planning of territories. The transport planning issues are resolved immediately after the planning of the city. Transport planning is based on the provisions of the General plan of the city. Organization of urban traffic should be considered as a continuous process of forecasting – planning – design – construction. In the organization of road traffic, public passenger transport should be considered as a priority, as an alternative to a car, even with a certain amount of discrimination. Among the possible solutions to the questions of organization of traffic at signalized intersections include the use of multi-program traffic lights regulation (at least three programs) that allows you to change the duration of a traffic light cycle, permitting phases at a fixed value of the cycle and intermediate cycles depending on clock download site. Equipment management systems of traffic on the road network, modern technical means of regulation. The definition of "acceptable system of urban road traffic is largely dependent on the degree of customer satisfaction (the movement). And it varies. It is influenced by many factors, such as the size of the urban agglomeration. It is quite clear that it is impossible to achieve the same results in settlements with population more than 1 million people and less than 100 thousand
