Abstract
The synthesis of regional (urban) road transport freight system topological structure enables the assessment of impact exercised by various structural characteristics on the functioning of the system. For this reason the quality of project solutions in the stage of system structural synthesis increases. Models of optimisation and simulation (included into the simulation procedure of optimisation of topological structure) have other possibilities as well. For instance, simulation model enables the solution of such various objectives of functional analysis of systems as, for example, the efficiency comparison analysis of stability of structure undergoing the changes of meanings of system parameters, the analysis of managing impacts of various types, loading technologies, etc.
Highlights
Among other things, the technology of transportation involves the provision ofservices, i.e. freight haulage
The efficiency of technological operations may be defined in the terms of the following factors: consumption of energy and materials per tonlkrn and quality and intensity of hauls
The purpose of the topological synthesis of freight road transport system embracing a set of commercial enterprises in the region En, the route between the points D and the flow of goods A k, is to divide the settlements of a region into zones serviced by the warehouses
Summary
The technology of transportation involves the provision ofservices, i.e. freight haulage. Technological operations of haulage should ensure safety of goods and be environmentally - friendly. Even the most advanced transport facilities may be not efficiently used. The overall technological process of transportation should be improved. To achieve this numerous tests should be conducted, involving the determination of flows of goods, their constant control and forecasting, road network and traffic optimization, etc. The problems of improving freight transportation in long hauls and the carriage of [20-40] tons of goods were analysed in [1-5]. The analysis ofcarriage of goods of50-1500 kg over small areas by transport facilities, say in the city, with the bottlenecks on the roads and ecological limitations in force,. In the present investigation some solutions to the above problems are offered
