The main purpose of this article is to present the deployment process of a military contingent to an overseas theatre of operation in the light of NATO standards and requirements. In particular, attention has been drawn to the economic aspects associated with planning and executing an operation and also other important problems connected with supply chain security.An attempt has been made to show the in-theatre transport system organisation in-cluding procedures and capabilities of military airlift and sealift.

Эксплуатация морского транспорта подвержена влиянию множества факторов, учет которого требует высокой трудоемкости. Как правило, моделирование морских транспортных систем, выступающих в роли связующего звена различных экономических процессов, производится на стадии предпроектной разработки. На этой стадии, помимо прочего, необходимо оценить влияние на проектируемую систему не только детерминированных, но и стохастических процессов. В данной работе описан алгоритм учета влияния ветро-волновых режимов морских участков на эксплуатацию морских транспортных судов. Данный алгоритм реализован на примере модели системы поставок сжиженного природного газа (СПГ) морским транспортом потребителям г. Мурманск. Научной новизной данной работы является комплексный подход к логико-математическому описанию эксплуатации морских транспортных средств. Этот подход включает в себя моделирование эксплуатации судна на базе агентного подхода, моделирование ветро-волновых режимов на основе анализа временных рядов и стохастических экспериментов и определение скорости движения судна на основе эмпирико-статистических формул расчета скорости судна и теории гидродинамики судна. В ходе выполнения данной работы была построена имитационная модель поставок СПГ в г. Мурманск морским транспортом. Результаты прогонов этой модели были верифицированы на основе технико-экономического обоснования АО «ЦНИИМФ». Алгоритм построения имитационной модели, описанный в данной работе, может быть применен для имитационного моделирования морских транспортных систем с различными целями функционирования. Marine transport operation is affected by a lot of factors taking into account of which requires a high laboriousness. In most cases modelling of marine transport operation as a link in various economic processes is performed at the pre-design development stage. By the way, evaluation of the impact of both deterministic and stochastic processes on the designed system is necessary at this stage. Evaluation of transport system efficiency based on pre-formed system of criteria is in progress at this stage. This paper describes an algorithm for modeling the operation of marine vessels taking into account wind-wave regime of sea areas. This algorithm is implemented by the model of liquified natural gas (LNG) supply chain system by marine transport to consumers of the city of Murmansk. Scientific novelty of this paper is a complex approach to logical-mathematical description of marine vehicles exploitation. This approach consists of agent-based simulation of vessel exploitation, modelling of wind-wave regimes by means of time series analysis and stochastic modelling and the speed determination of the vessel movement based on the empirical-statistical formulas for calculating the speed of the vessel and the theory of vessel hydrodynamics. During this research simulation model LNG supply chain system by marine transport to consumers of the city of Murmansk was developed. The results of the model have been verified by the feasibility study performed by CNIIMF JSC. The algorithm for constructing simulation model described in this paper could be implemented in modelling of marine transport system for various purposes.

The development of megacities leads to changes in the existing street and road network and an increase in motorization. This paper provides an analysis of the transport system of St. Petersburg and the dynamics of the main indicators. The effect of motorization on intersections and on traffic lights as objects of the supply chain is considered. An overview of the main tools for studying intersection congestion is given, and ways to calculate bottlenecks using circular intensity diagrams are proposed. Traffic volumes during morning, afternoon, and evening rush hours were collected as input data for the study.

Competition between material and energetic use of wood – also a question of allocation The amount of wood used for energy purposes has recently strongly increased in Germany. This has resulted in a competition for some wood assortments between raw material and energy uses. This has led to price increases and supply bottlenecks in wood industries facing international competition. An easing of this tension can be achieved by an increase in the volume of wood harvested, changes in the allocation of the assortments, alternative silvicultural concepts and optimized harvesting techniques. Moreover, an improvement in efficiency of the supply and conversion of energy wood increases the potential of wood. Whether wood is to be used for material or energy purposes is not only determined by economic aspects: the risks which have been taken into account, the investment which has been made, but also the obligation to deliver because of regional political structures can be decisive reasons for the allocation of wood. More research is needed to clarify the question of whether and in what way stakeholders within the supply chain influence the decision making process.

The hinterland leg of maritime containerized transport as a part of supply chain has been increasingly pressured by larger volumes, as well as by a need to fulfill sustainability requirements that are expressed by social opinion and formal regulations. There is a potential to relieve this pressure through integration of a dry port, as a seaport’s inland interface, in the supply chain. Therefore, this paper aims to explain how a supply chain can benefit or enhance its outcomes of cost, responsiveness, security, environmental performance, resilience, and innovation, by the integration of a dry port. The data for this case study is collected through interviews and site visits from the privately owned Skaraborg dry port, Sweden; and the study is limited to the actors of the transport system involved in the development and operations of the dry port integrated setup. The results show that the six supply chain outcomes (cost, responsiveness, security, environmental performance, resilience, and innovation) are perceived by the actors as being desirable, and can be enhanced by the integration of a dry port in the supply chains. In particular, the enhancement of the supply chain outcomes can be achieved due to intermodality and reliability of rail transportation and customization of services associated with the dry port integrated setup, and by increasing the capacity of transportation system.

Multimodal transport terminals are the elements of transport systems that ensure the interaction of enterprises of various modes of transport. The effective functioning of transport terminals significantly affects the efficiency of the material flow servicing in a supply chain and the sustainability of the whole transport system. The paper proposes an approach to determine the optimal parameters of production resources in multimodal transport terminals, based on numerical computer simulations of technological operations in a transport terminal for the given parameters of incoming and outgoing material flows. The practical use of the proposed approach is shown on the example of the Amur Harbor cargo area of the Dnipro River Port.

Heading towards sustainable logistic is a popular tendency. However it is widely discussed in case of supply chain, there are many studies concerning warehouse and warehousing. Introducing and developing sustainable warehouse solutions is often a challenge. In the article, the authors analysed the literature sources (scientific publications and professional studies) to indicate directions and changes in technological, managerial, social, environmental and economic aspects of warehouse functioning that are required to go forward to sustainable tendency. To summarize the studies, the application model presenting assessment of the status of sustainable warehouse is proposed. The purpose of this model is to provide policy-makers insights to identify actual state of warehouse in a company and perspectives of its development.

Green degree evaluation is one of the key problems to Green Construction Supply Chain (GCSC) Management. The influential factors of GCSC green degree can be analyzed from resource saving, pollution reduction and economic aspects. And the basic evaluative indexes of GCSC are discussed. Then, a GCSC evaluation model is proposed based on Data Envelopment Analysis (DEA). The application case shows the feasibility of the method for GCSC evaluation.
