Description
The decisions of many-aims optimal transport tasks are enough complicated in realization. The difficulties defined not only by a number of aims of optimization, but a number of conflict variants of decisions while achieving different aims. That is why, similar tasks like the tasks of vector optimization. According to this, the article deals with the problems of choice and adoption of decisions and modeling, meeting while using number vector schemes on iteration of searching

Description
In the article, we present the results of the simula-tion changes of electrical parameters of IC under the influence of static radiation, which obtained in theoretical and experimental studies. We developed physical and mathematical models and software for calculating parametric reliability by polar IC, which takes into account the temperature of environment and mode of the products

SANITARY CONDITION OF TREES IN URBAN PLANTINGS (ON THE EXAMPLE OF VORONEZH)
DescriptionThe article presents a comparative analysis of the sanitary condition of green plantings in park area and street network of trees of local forest origin and exotic species

Description
In this article, the special classification of logging machines and technologies of carrying out cleaning cutting is considered. The mathematical model of quantity of the damaged trees, remaining after cleaning cutting in coniferous plantings is described. The decision of optimization problem of quantity of damaged trees and productivity of logging machines at cleaning cutting is submitted. Possible decrease of quantity of damaged trees is shown, due to use of the automated choice of system of logging machines

IMPROVEMENT OF THE CALCULATION OF THE PROFILE VOLUME OF EARTHWORKS IN COMPUTER-AIDED DESIGN SYSTEM
DescriptionDependences for calculating the volume of earthworks profiled in computer-aided design system (CAD) are presented, taking into account the change in the parameters of the transverse profile of the subgrade of the road, the slope of the hillside. These function are used in computer-program of calculating the volume of earthworks profile, which allows us to calculate both the volume of earthworks profiled on the projected area of the road, and the amount of work on the mounds and excavations on the specific pickets, which allows to differentially estimate the distribution of ground masses for the development of technological processes of construction of subgrade, and it is also a source of information for the design of reserves and stockpiles of soil in CAD

AUTOMATIC CONTROL SYSTEM OF CHARACTERISTICS OF DEVICES OF MOVING ON THE AIR PILLOW
DescriptionMethods of jet pneumoautomatics with reference to devices of moving on an air pillow are considered. The local system constructed on the basis of methods of jet pneumoautomatics, for management of thickness of an air pillow is shown. In clause the opportunity of automatic removal of dusty air from a working zone of pneumotransport system is reflected. On the basis of hydro dynamical calculation parities for engineering calculations of values of

MODELS AND METHODS OF CONTROL SYSTEMS OF ECOLOGICAL SAFETY OF FOUNDRY MANUFACTURE
DescriptionThe given developments are devoted to modeling of control systems by ecological safety of foundry manufacture. In a working zone of foundry shops except for a dust the significant amount of polluting substances is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The given dust is most dangerous to health of the working personnel and creates problems when clearing the air
