Оптимизационные модели управления ограниченными ресурсами в логистике
The proposed monograph considers optimization models for managing limited resources in logistics systems. Such systems are primarily applied by industrial, transport and trade companies, including wholesalers.
As a rule, the efficiency of these companies depends in most cases on how rational the limited resources are used. Among the resources are the following: production assets, labor force, manufacturing equipment, vehicles, etc. The work studies various approaches to manage such resources when the situation is quite stable or even well-known (the characteristics of the situation can be clearly described) and, on the contrary, when some parameters of model are not specified exactly. In the first case, deterministic models are in focus of research, in the second one, stochastic models are offered. Nevertheless, the authors of the work evaluate the stability of functionality and solution structure in the models if various risk events occur.
The monograph is intended to senior bachelor’s degree students, master's degree students and postgraduates specialized in "Management" and "Logistics" as well as to the specialists interested in logistics systems design.
Despite over 30 years of worldwide reforms in many directions to increase efficiency, public transport markets present a variety of arrangements regarding operations, control and ownership that are amenable to improvement. This workshop will examine the contextual economic, political, cultural and social factors behind these many different cases that can be observed around the world. Through a better understanding of such factors it will examine the competition and ownership options for regulated public transport markets, taking full account of local contextual factors. This will include examination of methods for improving performance without major competition and ownership changes, for example by improved institutional design (both top-down and bottom-up), the development of trusting partnerships, the promotion of negotiated contracts and the introduction of optimal operating rules.
This volume discusses post-socialist urban transport functioning and development in Russia, within the context of the country’s recent transition towards a market economy. Over the past twenty-five years, urban transport in Russia has undergone serious transformations, prompted by the transitioning economy. Yet, the lack of readily available statistical data has led to a gap in the inclusion of Russia in the body of international transport economics research. By including ten chapters of original, cutting-edge research by Russian transport scholars, this book will close that gap. Discussing topics such as the relationship between urban spatial structure and travel behavior in post-soviet cities, road safety, trends and reforms in urban public transport development, transport planning and modelling, and the role of institutions in post-soviet transportation management, this book provides a comprehensive survey of the current state of transportation in Russia. The book concludes with a forecast for future travel development in Russia and makes recommendations for future policy. This book will be of interest to researchers in transportation economics and policy as well as policy makers and those working in the field of urban and transport planning.
The aim of the article is to present the ways of urban public transport development in Russia within the context of the transition towards the market economy. The article consists of two blocks: the trends of urban public transport development in the Russian Federation and the problems of urban public transport management. The first block presents the survey of urban public transport development trends by transport mode with the attention to the mass transit. The quantitative and qualitative analysis of urban public transport in Russian cities since 1991 is provided. The positive and negative cases of urban public transport development are revealed. The most important features of urban public transport functioning connected to the urban planning and transport planning practice are discussed. The second part presents an overview of the main decisions made by public authorities in the field of urban public transport management. The key questions are: the general logic of administration, the role of private transport operators, funding and risks of the market participants. The general conclusions reveal the place of the Russian Federation within the context of world urban transport development trends.
Logistics service has a significant impact on both the effectiveness of the companies receiving logistics service and the productivity of the companies which provide it. The provision of the common level of service for all customer groups leads to the inefficient use of the available resources of the company: the less profitable customers receive high levels of services, while the most commercially viable ones, on the contrary, get excessively low levels of logistics services. The case like this is the result of a lack of the thoughtful approach to the elaboration of the customer service policy from the perspective of logistics. The previously published article proposed a new approach to the development of the customer service policy in terms of logistics in the generalized view. Only the first stage “Strategic basis of service policy” was defined in a detailed way. The current article intends to offer the ultimate presentation of the integrated approach to the elaboration of the customer service policy from the perspective of logistics with a detailed description of the other four stages. The approach established is the result of the generalization, critical analysis and reconsideration of the existing best practices in the development of service policy for the company as a whole, in the formation of logistics service, in the customers’ support provided by service provider, in the consideration of the peculiarities of logistics activities. The article work out the stages of the elaboration of the customer service policy from the perspective of logistics and reveals the nuances of the development of logistics service. As well, the concept of “standard of logistics service” is refined. The proposed approach lays the foundations for the logistics service management: to some extent it helps to plan logistics services being provided. Despite the comprehensiveness and systematicity, the approach is flexible to account special features of its application to organizations acting in various business fields. The article demonstrates the transformation of the approach incorporation on the example of the manufacturing and trading companies as well as logistics providers.
This paper examines the actual problem of urban infrastructure of the city and the reaction of young people to changes in the public transport system in Nizhny Novgorod. During the survey 331 respondents (16-30 years old) were questioned about which types of public transport they use; about the attitude towards changes in the transport system and the system as a whole
We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.
