  • Logistics models of technological outsourcing in transport and logistics systems

    The implementation of market mechanisms in the transport and logistics system of the railway industry contributes to the development of competitive relations between market participants and stimulates the search for new ways to gain a competitive advantage. Technological outsourcing of industrial enterprises can strengthen the position of operator companies in the market and increase the efficiency of organizing the movement of car traffic on the railway network by redistributing responsibilities in the supply chain. Possible options for organizing interaction between operator companies and industrial enterprises and a model for organizing technological outsourcing are considered. The general structure is represented schematically in a graph formulation by bipartite graphs with various types of one-to-one, one-to-many relationships. Optimization mathematical models of the logistics of such interaction with different levels of generalization in nonlinear and combinatorial formulations are presented, adequately reflecting the practice of using technological outsourcing.

    Keywords: Transport and logistics systems, technological outsourcing, operator activity, one-to-one, one-to-many interaction mechanism, linear integer programming

  • The model of agent activity in transport, logistics and technological systems

    Agents of the transport and logistics market (TLM) in the implementation of their activities implement solutions aimed at maintaining and developing their position in the market through active interaction with counterparties (cooperation, diversification of capital and activities) in changing environmental conditions. The limited volume of transport services and changes in its structure require formalization and systematization of possible actions of agents. The paper provides an analysis of the factors influencing the activity of TLM agents, their formalization and schematic solutions for the implementation of their activities.

    Keywords: transport and logistics market, activity, market agent, stability, formal model, efficiency indicator, profitability of services, logistics chain, volume of transport work, railway transport

  • The object model of urban transport system in optimal control

    The problems of formation of object models of urban transport systems to adequately reflect the essential object-relationships to achieve management goals. Technical and technological aspect submission sites solve the problems of reliability and sustainability of the transport system, the economic - solves problems of reducing losses in the organization of transport and passenger flows, socio-economic - reducing the environmental impact on the environment, road safety. Held presentation variant analysis object models with different target installation in optimal control problems.

    Keywords: The object model, the transport system of the city, optimal control, traffic safety, traffic management

  • Formation of high-speed routes in the urban transport system

    The problems of organization of the movement "express route" in the urban passenger transport. The algorithm and the calculation of time-saving passenger in the formation of the route in the operating mode "express".

    Keywords: urban passenger transport, speed, time-saving, transportation route, "express route" traffic, street and road network, ridership

  • Principles and provisions of the common information space of the transport market

    There are principles that are included in the basis of common information space. The most of all principles are relevance, predictability, specific, response time, institutional, security. The article consider technical aspects such as the distribution of computing power on the basis of the properties of parallel processes, systems requirements (scalability, distribution), logistics principles of information flow, the implementation of the functions of information processes. The article describes the technical, economic and legal basis of common information space. Since railway trasnport includes a number of developments, the implementation uses the principles of reengineering such as optimality, adaptability, redundancy, rationality, vertical, horizontal, intensity etc ...
