Activities fotr timely removal of growing unwanted tree and shrub vegetation (TSV) for the maintenance of transport linear infrastructure facilities in proper condition in accordance with the requirements of a number of regulatory documents have been organized. Taking into account previously revealed insufficient study of the issue of determining the possible effectiveness of the use of certain technological processes for TSV removal in various natural and industrial conditions, the purpose of the study was to determine the values of capital investments for the formation of machine systems, mechanisms and equipment for the implementation of technological processes for removing unwanted tree and shrub vegetation from territories of linear infrastructure objects (LIO). A system of machines, mechanisms and equipment of various technical levels and price categories was proposed to implement the research goal of removing TSV from the territories of LIO. The system corresponds to modern concepts and trends in the development of technology in the field of logging and forestry. With the help of mathematical apparatus proposed in the article, the author has obtained intervals and amounts of capital investments for the formation of machine systems for the most characteristic technological processes for removing TSV. The term "plateau of capital investments for the formation of machine systems" has been proposed and recommendations for production on an economically justified comparison of a number of technological processes in order to identifying opportunities to replace them have been made.

The article analyzes, systematizes and evaluates the demand for machines, mechanisms and equipment used to remove uncontrolled tree and shrub vegetation from the territories of linear infrastructural objects. The existing technological processes that form exclusively mechanical methods of removing unwanted tree and shrub vegetation are analyzed. The technical means of mechanization of work on the elements of the technological process used on the territory of linear infrastructure facilities are systematized. The predominant use of a specific number of technical means by implementing organizations is shown, indicating their characteristics and the main defining criteria of demand. It has been established that there is almost complete absence of both small means of mechanization, allowing to reduce the share of manual labor when carrying out work to remove unwanted vegetation in hard-to-reach places of the cleaned areas, and specialized pick-up loaders of felling residues. The definition of a technical means of raking up unwanted vegetation is proposed and formulated as a «forest rake» It was revealed that in a number of regulatory documents there are incorrect names for motorized hand-type brush cutters, corresponding recommendations for production are given. The results of the work can be used by enterprises engaged in the maintenance and operation of linear infrastructure facilities.

To mitigate car traffic problems, the United Nations Human Settlements Programme (UN-Habitat) issued a document that provides guidelines for sustainable development and the promotion of public transport. The efficiency of the policies and strategies needs to be evaluated to improve the performance of public transportation networks. To assess the performance of a public transport network, it is first necessary to select evaluation criteria. Based on existing indicators, this research proposes a public transport criteria matrix that includes the basic public transport infrastructure level, public transport service level, economic benefit level, and sustainable development level. A public transport criteria matrix AHP model is established to assess the performance of public transport networks. The established model selects appropriate evaluation criteria based on existing performance standards. It is applied to study the Stonnington, Bayswater, and Cockburn public transport network, representing a series of land use and transport policy backgrounds. The local public transport authorities can apply the established transport criteria matrix AHP model to monitor the performance of a public transport network and provide guidance for its improvement.

Required Quality

The rational design of technological processes of parts manufacturing in single and small-scale production is inefficient without wide introduction of modern tools of part manufacturing automation with modern computer-based equipment and software. It is desirable to carry out of automated synthesis of single route technological processes with minimal influence of the operator on the technological environment. The technology of computer-aided design of technological processes is used to develop effective algorithms of functioning of adapted systems for control of technological processes and their implementation when taking into account interrelations with the technological environment. Automated development of technological environments of a given level of design concerning a dedicated technical system is possible on the basis of their rational functional models, created by means of CALS-technologies. The rational use of the SADT methodology with application of the principle of decomposition and development of the SADT-diagrams allows to solve the given technical problems. Therefore, the purpose of this paper is to develop and study the vibrational-centrifugal surface strengthening at the finishing and hardening technological operation to provide the required quality parameters and operational characteristics of the parts. The object of this research is a finishing and hardening technological operation. The subject of this research is method and parameters of vibrational-centrifugal surface strengthening to provide the required quality parameters and operational characteristics of the parts. The development of SADT diagrams allows to divide the technological process to technological operations, cutter–setting positions, technological steps, main machining steps etc. In this paper the principles of control of technological operation for vibration-centrifugal strengthening of surfaces of parts are suggested. The experimental device for machining of inner surfaces of parts is described. The initial and detailed model of the operation of the vibrational-centrifugal strengthening is offered. Statistical and structural analysis of technological process made it possible to establish the influence of the parameters of the vibrational-centrifugal strengthening on the geometric and physical-mechanical parameters of the surface quality and associated operational characteristics. Further research in that field will be related on the development of practical recommendations for using of the vibrational-centrifugal surface treatment for improving of the geometric and physical and mechanical parameters of parts surfaces.
