Логистика: современные тенденции развития: материалы XVI Междунар. науч.-практ. конф. 6, 7 апреля 2017 г. Ч.2
In the article there is a short literature overview of current trends in assessment of freight transportation performance, pointed out their’ advantages and disadvantages. The author has analyzed some foreign literature sources that allow saying about the complex attitude to the studied issue. Also there are concerned perspective methods of freight transportation assessment.
Variety of inventory management models known in logistics theory. Design of models for inventory management in a multi-level inventory placement systems are popular field of studies nowadays. One such model is Sven Aksater’s model. Like most models, it is applicable in cases where all the main parameters – demand per day, delivery time, the volume of orders, delay in logistic cycles and etc. – are deterministic. Obviously, in practice these parameters are random variables. The article presents two models for the economic order quantity calculation for two-leveled supply placements system, taking into account safety stocks and deficit at different levels, depending on the inventory management strategy – with fixed order amount or fixed time interval between adjacent orders.
The structure of the applied theory of the logistics systems design and planning continues to evolve in the circumstances of supply chain integration. The synchronization of material, service, information, and intellectual flows offers new opportunities for cross-disciplinary analysis. The article considers the development of conceptual framework, as well tactical and operational levels (e.g. existing terms and definitions, economic indicators, methods and models) that are applied in the research on the creation of value nets in terms of their flexibility, speed and reliability.
Sustainable regional economic growth depends on many different factors and one of the cores is its security by the infrastructure. The question of infrastructure is quite complicated both for the analysis – because the infrastructure needs to be analyzed as a complex of objects, and for the business infrastructure projects are usually huge investing projects. The aim of this research is to conduct a comprehensive Saint Petersburg Logistics Infrastructure analysis.
This article reviews the modern approaches to the analysis of conflict situations in a supply chain. Four main areas of conflict analysis are identified and discussed in the paper: mathematical methods, hierarchical analysis, total cost modeling business processes.
