Resource-saving factor in the development of Russian cities

The purpose of the article is to identify the problems of Russian cities and urban-type settlements from the standpoint of their historical and economic development. Using the methodology of economic, statistical and retrospective analysis, it was revealed that along with the growth of large cities in recent years, there has been a tendency towards a reduction in small settlements, which is associated with a decrease in industrial production. The result of this is the active development of urban processes, leading to the concentration in large cities of the scientific, technical and intellectual and production potential of the regions, their transformation into self-sufficient centers for the development of territorial socio-economic locations. The result of the study is the substantiation of the need to create new methodological approaches to the development and placement of productive forces, planning of urban areas, solving problems of energy and resource supply of territories on the basis of achieving their ecological and economic efficiency. The concept of the decisive role of the resource-saving factor in the process of urbanization of territories is substantiated. It was revealed that the approach to the analysis and modeling of the city economy when considering it as a "quasi-corporation" involves the formation of an integrated reproduction system based on increasing the efficiency of the use of territory resources, which translates the process of planning the development of the urban environment into the category of business process technologies

Development of a Mathematical Model of Eevaluation of Road-and-transport Assets as a Component of Information-and-management System

The mathematical model of evaluation of road-and-transport assets based on the level of real qualitative state was developed. The study was performed in connection with the lack of evaluation methods that take into account specifics of the assets of the road-and-transport complex. This problem is caused by absence of scientifically substantiated criteria for property evaluation of road assets.As a result of this study, the conceptual model for evaluating the road-and-transport infrastructure assets was developed. Unlike the conventional approach, the constructed conceptual model of the evaluation procedure is based on application of a qualimetric model and a multilevel hierarchical system of indicators. This approach has enabled elucidation of the real physical wear converse to the level of qualitative state of the asset which is the basis for a fair evaluation.The conceptual model of evaluation was laid in the basis of construction of a mathematical model that, in contrast to the conventional approach, takes into account the qualitative state of linearly extensive objects. The disadvantages of application of the developed mathematical model include the necessity of estimation of errors and the level of expert competence. However, the calculations made in testing of this model gives the right to assert fairness of the asset evaluation which is an input parameter to the information-and-management system of the road-and-transport infrastructure.The study results create a favorable environment for making managerial decisions on the assets as the objects of management in the road-and-transport complex and can be used by enterprises and organizations of the comple
