Analysis of methodical approaches to the assessment of transport-logistic system of the city
The article presents an overview of methodological approaches to the assessment of complex socio-economic systems, which are based on the system and process approaches, economic and mathematical modeling, and are concentrated in the following areas: assessment of freight and passenger traffic, costs and time, logistics services and infrastructure, demand and entropy. This leads to the development of algorithms for the behavior of participants in all processes that do not fully affect the entire transport and logistics system (TLS) of the city. But today, no attention is paid to the assessment of the transport and logistics system of the city, which takes into account the entire total traffic flow. This allowed the author to propose the concept of designing such systems through urban transport and communication corridors (UTCC) and for the main objects of research (mass, individual passenger transport and logistics supply chains) and taking into account future technological changes. It is noted that the city's TLS is characterized by a plurality of functioning: decentralization, centralization and self-organization. For objects in the system of centralization proposed stages and criteria for achieving the goals, and the management of the system can solve a decentralized multi-agent system (MAS). An important unifying element for all objects is the synchronization of the total traffic flow, where the MAS is one of the most important elements of coordination of all processes. To control the self-organization of the city's TLS, an entropy indicator is proposed as an indicator of the stability of the UTCC and the system as a whole. Today in the development of technology is not enough paid to the design of the city's radar station, taking into account the future factorial impact, technological and other changes. Reorientation to new research areas and technologies will create a «breakthrough» for more intensive development in cities and the economy as a whole.
