Aleksandr Rakhmangulov is professor of Logistics and Transportation Systems Management at Nosov Magnitogorsk State Technical University since 1988. He got the degrees of PhD and Dr.Eng. at Russian University of Transport - RUT MIIT. His main research field is simulation and mathematical modelling of transportation processes and systems, traffic designs, management of the railway systems, green logistics, maritime and intermodal freight transport and the research covers sustainability, information systems and technology evaluations.
Sustainability of the open pit mining and technical system (MTS) is one of its key goals in the changing conditions of the external and internal environment. All MTS’s subsystems must function in concert to achieve this goal. The structure of the MTS is formed by many subsystems and elements, which are evaluated by a significant number of indicators. A comprehensive assessment of the MTS for all possible indicators is a complex and time-consuming task. However, each subsystem and element of the MTS has a different effect on the sustainability of this system. The MTS’s parameters change significantly during transition periods, for example, at a new stage of open-pit mining or when switching to an open-underground method of developing mineral deposits. The MTS’s sustainability declines during the transition periods. Changes in the parameters of technological processes during these periods can have a negative impact on the state of the economic and social subsystems of mining enterprises, as well as on the environment. Ensuring the sustainability of an MTS during transition periods requires the development of new approaches and principles for managing the work of mining enterprises, based on the alignment of economic goals, with goals in the field of ecology and social development. The study substantiates the key role of one of the MTS subsystems—the opening-up of an opencast system (OOS). It is shown that this system has a decisive influence on sustainable functioning and development. The systematization of the principles of sustainable functioning and development of mining enterprises and its systems has been carried out. Four groups of principles are distinguished: system-wide principles of management, principles of development of mining enterprises, principles of MTS development, and principles of the MTS’s subsystem development. The proposed system of principles is based on the idea of a sequential transformation of the subsystems at all stages of design and operation. A feature of the proposal system of principles is the consideration of economic, social, and environmental aspects to ensure the specified parameters for the sustainable functioning and development of mining enterprises. The results of the analysis of the factors of the external and internal environment of the MTS are presented. The parameters and indicators for assessing the sustainability of OOS and MTSs were selected and substantiated. The justified parameters and indicators were ranked using the fuzzy Analytic Hierarchy Process (AHP). The results of the assessment showed a high convergence of expert opinions on a group of economic parameters, which were rather high in technical and technological parameters. However, there is a divergence of expert opinions on social and environmental parameters. As a result of the study, it was concluded that the current management decisions are aimed at ensuring the economic and technological sustainability of MTS functioning, while achieving the goals of sustainable development of this system is not ensured. The methodology developed and presented in the study can be used to assess the sustainability of the functioning and development of MTSs.

Due to numerous uncertainties such as bad weather conditions, frequent changes in the schedules of vessels, breakdowns of equipment, port managers are aiming at providing adaptive and flexible strategic planning of their facilities, especially intermodal terminals. In this research, we investigate a two-stage optimization of intermodal terminals main parameters via using AnyLogic simulation platform. We have developed a set of hybrid simulation models to optimize the main parameters of intermodal terminals which are also called dry ports. To make an express evaluation of the preliminary implementation of dry ports, we have developed an agent-based system dynamics simulation model to achieve the stable state of the main parameters of intermodal terminals. To clarify the obtained averaged benefits of the main dry ports parameters while the port managers make key decisions on the investments into implementation of intermodal terminals, we have developed an agent-based discrete-event simulation model of a seaport – a dry port system. We show that the combination of the agent-based modeling with other simulation approaches simplifies the process of designing simulation models and increases their visibility. The developed set of models allows us to compute the balanced values of the parameters, while an effective operation of a seaport – intermodal terminal system is achieved. On the basis of the provided case study on one of the busiest ports in China, we prove the adequacy and validity of the developed simulation models. Due to the lack of systematic approach to optimization of the main parameters of intermodal terminals in logistic industry, our findings set herein could improve the decision-making process related to the selection of strategic facility planning in the field of intermodal terminals.

The effective concept implementation of sustainable development in logistics and supply chain management is based on the use of management decision-making methods for changing the parameters of logistics flows. Decisions should be made based on the measurement and evaluation of the parameters and indicators of these flows. The complexity of managing green supply chains is associated with insufficient knowledge of the system of logistics flows indicators and parameters, as well as in the absence of methods for their comprehensive assessment. In the present work, an original system of indicators (indicators and parameters) of logistic flows in green supply chains is proposed. Managed parameters of logistic flows are identified, the change of which ensures the principles implementation of the sustainable development concept. The use of the fuzzy AHP-TOPSIS method for evaluating the performance of logistics flows in green supply chains is considered. A fuzzy model for managing the parameters of logistics flows has been developed. Changing the parameters of logistic flows in order to achieve the goals of the sustainable development concept is proposed to be carried out using the original system of green logistics instruments. The work presents a calculation implementation example in the logistics flow control system of the procedure for selecting green logistic instruments.

The continuous increase of trade between China and Europe brought congestion problems at major Chinese seaports. An effective way to solve this issue is to set up intermodal terminals often called dry ports. However, the dynamics of various influenced factors on dry port’s implementation calls for the adaptive and flexible planning of the terminal. This paper analyzes the shortcomings of previous research related to the dry port’s implementation from the perspective of the applied numerous parameters concerning evaluating its operational efficiency and sustainability. The operational efficiency and sustainability of a dry port are evaluated by the developed system of the main parameters. This system gives the understanding of how these parameters are interrelated between each other and fills the gap in studies of inverse interrelations between main parameters of a dry port. To fully understand the sustainability of the main parameters of a dry port, this paper puts forward the simulation models description of the developed system. The developed model is a practical tool to evaluate the reliability of hypotheses about the functional interrelations between the main parameters of the dry port, as well as to evaluate the sustainability of the system. Finally, in order to develop functional interrelations between main parameters, the data from several Chinese dry ports has been collected. Finally, the developed multi-agent system dynamics model has been validated in the case study of Yiwu dry port located in Zhejiang, China.

Lysogorsk deposit of roofing slates is one of the largest in the Ural. The deposit is composed of coarsefiber, medium- and fine-fiber slate. A feature of the Lysogorsk deposit is the presence of quartz and carbonate-quartz veins. The thickness of the veins and inclusions varies from the first meters in swells to the first centimeters in twitches. Sometimes quartz vein zones with a thickness of 6–15 m are observed. The veins are localized mainly in coarse-fiber slates and are practically absent in fine-tomedium-fibrous slates. Since the marketable products should be free from overburden and gangue, slate containing carbonate-quartz material is subject to selective excavation and separate accounting in the form of operational losses. The deposit uses two technologies for the extraction of mineral resources. The best part of slates is extracted with drilling and blasting to obtain raw materials used as surface dressing of roofing materials. Fine-fiber and medium-fiber slates are partially developed using diamond-rope equipment in order to obtain blocks used for the production of roofing tiles. The features of the Lysogorsky deposit, the mining technology as well as the requirements of legislation and consumers to the quality of raw materials make it necessary to develop methodological recommendations for justifying mining parameters and determining losses during production of roofing slates. The existing industry regulations and methods for determining mineral loss do not allow us to determine the volume of possible slate recovery at the sites of inclusions of carbonate-quartz dyke and the estimate the volume of loss of the mineral. The authors of the article develop a method for justifying the parameters of excavation blocks and calculating slate losses, which takes into account different combinations of incline angles of contact interfaces of single quartz inclusions and veins with respect to the direction of mining advance, as well as the parameters of drilling and blasting in preparation of rocks for excavation. Based on the calculations performed, the recommendations are given on the planning of annual volumes of mining operations for the exposed sections of the field. It is determined that the loss standards are 21.2% for the horizon of 584 m and 15.8% for the horizon of 578 m. To justify the loss for the underlying levels, it is recommended to use the developed method for determining the width of the excavation blocks and the losses.

Развитие общественного транспорта является эффективным способом уменьшения заторов на улично-дорожной сети и повышения эффективности перевозок пассажиров в городах. Повышение качества городских автобусных перевозок способствует привлечению большего числа пассажиров. В случае, если момент времени прибытия автобусов на остановочные пункты не прогнозируется, автобусы движутся с нарушением графика, что вызывает беспокойство у пассажиров. Это является одним из факторов снижения качества пассажирских транспортных услуг. В настоящей статье представлен метод прогнозирования моментов времени прибытия автобусов на остановочные пункты на основе цепей Маркова, учитывающий пространственно-временные характеристики движения автобусов. Предлагаемый метод прогнозирования позволяет упростить планирование пассажирами маршрута их передвижения по УДС и сократить время ожидания на остановочных пунктах. Разработанный алгоритм прогнозирования прибытия автобусов на остановочные пункты апробирован на реальных данных автобусного маршрута №114 (г. Харбин, КНР). Преимуществами предлагаемого метода являются малая погрешность результатов прогнозирования, а также простота использования метода и алгоритма его реализации.

Ежегодно на дорогах России увеличивается число транспортных средств, возрастает интенсивность и плотность транспортных потоков и, как следствие, возрастает дорожно-транспортный травматизм и обостряется проблема загрязнения окружающей среды. Если рост травматизма связан, в основном, с несоблюдением скоростного режима, то загрязнение окружающей среды происходит из-за увеличения времени нахождения автотранспортных средств в заторах. Поэтому для снижения уровня дорожно-транспортного травматизма и выбросов в окружающую среду необходимо обеспечивать равномерное продвижение транспортных потоков в городах. Одним из эффективных современных способов обеспечения равномерного движения транс-портного потока является использование систем транспортной телематики, в частности, систем управление дорожными знаками, дорожными табло и светофорной сигнализацией. В статье представлен анализ существующих систем и методов светофорного регулирования. Все проанализированные системы и методы основаны на использовании однородных данных – данных о стандартных параметрах транспортных потоков. Показана необходимость сбора и анализа дополнительных слабоструктурированных данных о факторах, оказывающих значимое влияние на параметры транспортных потоков в городах. В качестве инструментов анализа разнородных данных предложено использовать инструменты Big Data. Представлен алгоритм прогнозирования параметров транспортных потоков, основанный на оригинальной идее ресурсных потоков и сочетании методов Big Data («ближайшего соседа» и фильтра Калмана) с оптимизационным методом поиска минимального покрывающего дерева на ресурсных сетях, описывающих функциональные зависимости между фактическими и прогнозными значениями данных.

A major direction in the development of modern world transport systems involves the concentration of freight and traffic flows within international transport corridors and transport nodes in terminals and hubs. The changing role of rail transport is taking place under these conditions. Increased structural complexity and irregularities in cargo and railcar traffic volumes have been observed, despite the higher levels of transport equipment and technology standardization, the increased container transport volumes and consequent reduction in the cost of intermodal operations, and the interaction between different modes in transport nodes. This is largely due to the increasing need for cargo owners to lower logistics and warehouse costs, which is achieved by reducing the size of freight shipments and ensuring their uniform delivery. Moreover, privatization of the railway industry in certain countries and the sale of rolling stock to operating companies have made the coordinated management of rail fleets more difficult. The demand for improved efficiency of railcar traffic volume management in the case of complex structures is especially relevant for large railway nodes, particularly the transport systems of industrial enterprises. Here, the application of traditional approaches to the management of transportation processes involving individual elements of traffic flow (trains, railcars, locomotives) and transport infrastructure (railway stations, loading areas, rail hauls) leads to additional transport costs as a result of the increased length of time that railcars are located at the railway node. The aim of this study, therefore, is to provide improved methods for the management of RTVs at complex railway nodes based on a systematic review of RTVs in conjunction with transport infrastructure and traffic control systems. The authors review the case of a systematic approach to the organization and management of railcar traffic volumes, both for mainline rail transport and at railway nodes and industrial rail transport. This study investigates the impact of irregular railcar traffic volumes on railway node functioning by applying a dynamic simulation model of the transport system of a large metallurgical enterprise. The application of the original methodology for assessing the amount of information in the operational management system for rail transportation allowed us to estimate the effect of structural complexity and railcar traffic volume irregularities on the efficiency of the dispatch control system. The authors propose a new system of parameters and indicators for assessing railcar traffic volumes, taking into account factors of complexity and irregularity, and provide a comprehensive assessment of its effectiveness for railcar traffic volume management. For this purpose, a method of dynamic optimization of these parameters (dynamic programming) is selected. The main hypothesis of the study is that improved accuracy in parameter optimization for irregular railcar traffic volumes is achieved by adjusting the duration of the base periods which constitute the optimization period in the dynamic problem. In this study we have formulated a mathematical model for dynamic parameter optimization of railcar traffic volume on the basis of base periods of variable duration, with an algorithm for model implementation as well. Experimental verification of the effectiveness of the developed model and algorithm is conducted on the constructed process-centric railway node simulation model. Three series of experiments are conducted: without railcar traffic volume optimization, and with dynamic optimization of railcar traffic volume with the application of base periods of constant and variable duration. The experimental results demonstrate increased optimization accuracy with the use of the proposed model, reducing transport costs (time of railcar traffic volume handling) at the railway node by 11% on average. For the realization of the model and algorithm, a method is proposed for their integration in information management and intellectual transport systems.

The issue of operative data reception on location and movement of railcars is significant the constantly growing requirements of the provision of timely and safe transportation. The technical solution for efficiency improvement of data collection on rail rolling stock is the implementation of an identification system. Nowadays, there are several such systems, distinguished in working principle. In the authors’ opinion, the most promising for rail transportation is the RFID technology, proposing the equipping of the railway tracks by the stationary points of data reading (RFID readers) from the onboard sensors on the railcars. However, regardless of a specific type and manufacturer of these systems, their implementation is affiliated with the significant financing costs for large, industrial, rail transport systems, owning the extensive network of special railway tracks with a large number of stations and loading areas. To reduce the investment costs for creation, the identification system of rolling stock on the special railway tracks of industrial enterprises has developed the method based on the idea of priority installation of the RFID readers on railway hauls, where rail traffic volumes are uneven in structure and power, parameters of which is difficult or impossible to predict on the basis of existing data in an information system. To select the optimal locations of RFID readers, the mathematical model of the staged installation of such readers has developed depending on the non-uniformity value of rail traffic volumes, passing through the specific railway hauls. As a result of that approach, installation of the numerous RFID readers at all station tracks and loading areas of industrial railway stations might be not necessary,which reduces the total cost of the rolling stock identification and the implementation of the method for optimal management of transportation process.

Currently, container shipping development is directly associated with an increase of warehouse areas for containers’ storage. One of the most successful types of container terminal is an intermodal terminal called a dry port. Main pollution sources during the organization of intermodal transport are considered. A system of dry port parameters, which are recommended for the evaluation of different scenarios for a seaport infrastructure development at the stage of its strategic planning, is proposed in this paper. The authors have developed a method for determining the optimal values of the main dry port parameters by simulation modeling in the programming software Any- Logic. Dependencies thatwere obtained as a result of modeling experiments prove the adequacy of main selected dry port parameters for the effective scenarios’ evaluation of throughput and handling capacity at existing seaports at the stage of strategic planning and a rational dry port location, allowed ensuring the improvement of the ecological situation in a port city.
