This article describes the main problems of multi-objective optimization in management of the complex of forestry engineering machinery, as well as it proposes an option of implementation of the scheme of SPPR, which provides a solution of multi-objective control problems of the park of forestry machines
In this article the identification and the research of genetic algorithm key parameters of genetic schemes method and their influence on efficiency of optimum decisions search in expert systems of production type is conducted. The following parameters of genetic algorithm are considered: crossover operator, choice of parents pare, mutation operator, inversion operator
The article, on a simple numerical example, deals with the application of the automated system-cognitive analysis (ASC-analysis) and its software tools - intellectual systems "Eidos" for the detection and investigation of determination of emergent macro preferences of systems in their composition and hierarchical structure, i.e. the sub-systems of various complexity levels (levels of the hierarchy). The article briefly discusses some of the methodological issues of creation and application of formal models in scientific knowledge. The system generalization of the principle of William Ross Ashby about the necessary diversity on the basis of the system of generalization of the theory of sets and systems theory, information, generalized formulation of the principle of Galileo-Einstein, the hypothesis about its relationship with the theorem of Emmy Noether are offered; and also there is a hypothesis "About the dependence of the force and direction of the relations between the basic elements of the system and its emergent properties as a whole, on the level of hierarchy in the system"
A stress-strain state of landslide soil during interaction with piles has been considered. The dependences of the critical landslide pressures from soil non-squeezing condition have been given. It was established, that account of passive reaction of lower slope essentially increases resistance of construction against soil squeezing
The article presents the results of research, design development to automate the process of planting of seedlings and saplings with open and closed root system, in order to increase the operating speed, performance and level of mechanization, reducing manual labor and increase its security
The results of theoretical research of process of anaerobic fermentation of bird dung are brought in the article. In theory, the structurally-technological chart of fluidizer is reasonable utilization of bird dung, the structural and regime parameters of the offered setting are reasonable
Description of hydro kinematic scheme of forest manipulator with additional damper connection is given in the article. Optimal damper parameters for manipulator dynamic loading decrease are defined on the basis of operation mathematical model solution
Dependences 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
The presented technique of optimizing adequacy and requirements feasibility for electronic component-component base includes expert evaluations method data requirements, as well as an algorithm of optimization and aims to support decision-making in the planning work area on capacity-electronic components
On the basis of a field experimental research, the efficiency of a bush cutter with vegetation supporting device is studied, at processing of sites with vegetation of various tree species and a various average thickness
