ABSTRACT

The paper reviews well-known routing problems (Vehicle Routing Problem, VRP), that are an essential part of the transport logistics. The mathematical models of various routing problems’ classes are given: with account to a transport vehicle’s carrying capacity (TV); with the time windows; with split delivery; with a given planning time horizon (periodic problem); with backhauls; with satellite facilities. Since the routing problems are the NP-hard objectives of combinatorial optimization, for the sake of their practical application in the sphere of the transportation management the various heuristic algorithms are being developed. The known metaheuristics are expounded in the paper that present the local search algorithms as well as constructive algorithms, namely, the genetic algorithm; the evolutionary strategies; the ant colony algorithms’ series; the alternating neighbourhood search algorithm. Herewith, the attention is paid to the solution coding and to some neighbourhood constructing solution operations. Since in practice the routing problems are closely connected with the goods disposition within the transport vehicles (the 3D packing problem), the approximate algorithms which provide obtaining the goods packing map are described. The given review of various routing problems’ classes and the effective methods of their solution aid in practical problems of the effective routes search for the goods delivery to various customers. So, Part 2 of the paper describes the mathematical model and the methods of one practical task resolving that is processed together with the 3D packing problem of goods inside car transport vehicles.

ABSTRACT

The search and design of links between the company’s performance indexes and results of logistics activity nowadays is a relevant tool for increasing competitiveness of Russian companies. Situations, when the influence of certain logistics costs groups on financial performance indexes is underestimated, occur considerably often. And in these cases it is meant huge amount of financial resources involved. Thus, the attempt of designing the analytical models for assessment the correlation between logistics and business performance indexes is a relevant issue, which requires further investigation and improvement.

In the article given the analysis of Russian and foreign literature sources, devoted to the topic studied; identified the main trends and given the possible way for further investigations. The article has analytical models for assessment the influence of different logistics costs groups on ROI (return on investment) index; numerical example is given.

ABSTRACT

The analysis of scientific works devoted to the formation of Key Performance Indicators (KPI) of transport services shows that the long-term path includes the consolidation of a number of basic (key) indicators, the definition of auxiliary indicators, as well as the definition of the company's place among competitors. It is possible to form the appropriate set of models for the calculation of following basic indicators. Productivity (for example, hourly productivity); time parameters (transport time, time for paperwork, time for loading and unloading, etc.); transportation costs (cost of transportation, loading and unloading, storage costs, return flow, etc.); reliability (probability of failure, sustainability of the process and time parameters). We are proposing the original two-level structure of a transport company performance indicators and the model for calculating KPI for assessment of various transport types, that can be used as a basis for development of software contributing to digitalization of transport services.

At present, any enterprise solves logistics tasks. With cargo transportation, such tasks can be solved more quickly, giving companies and their customers a single platform for interaction or cloud services. Recently manufacturers and suppliers of logistics services have been using cloud computing technologies more and more to reduce their costs and optimize business operations.

Cloud computing technologies have a huge impact on modern economy. This article considers the role of cloud technologies as a tool of logistics outsourcing in the transportation market as due to information and Internet technologies development, it is becoming increasingly possible to introduce the latest techniques in logistics. To assess the impact of cloud services, the main advantages and disadvantages of cloud logistics, as well as the prospects for the development of cloud services in domestic logistics activities are highlighted.

Various innovative technologies allow transport operations to proceed smoothly and quickly. At the same time, cloud computing technologies in logistics do not only increase the reliability and efficiency of operations, but also provide a reduction in transportation costs. Using cloud-based systems, logistics providers receive an effective planning and supply chain management tool to improve the level of customer service.

ABSTRACT

 Transport efficiency assessment today is an important issue of modern logistics management. According to the summarizing of different literature sources, transportation occupies the biggest part of total logistics costs.  The challenge of designing efficiency transportation indices deserves special attention. Hereby some questions still need consideration, such as what an assessment system should look like? What issues should be considered while conducting analysis of transportation activity? Is there any complex of assessment indices that could be proposed? The article attempts to answer all these and other questions of logistics management based on works of Russian and foreign researchers. The article will be useful for scientists and specialists dealing with efficiency assessment issues

ABSTRACT

 The major market for crude oil, which is produced in the Caspian region, and petroleum products, produced at the southern refineries of Russia and CIS countries, is the South European countries market. The transport infrastructure of these countries for delivery of oil products to consumers is designed for sea supply. In this work special attention is paid to the condition and development of port terminals and transport systems connecting port tank farms with consumers of oil products. The main capacity of the oil industry in the south of Europe is concentrated in the most developed countries. The method of quantitative analysis is used to study the transport infrastructure possibilities and the production of petroleum products in this region under study. With the help of this method it is possible to establish the correspondence of the transport infrastructure possibilities with expected and existing freight flows. The analysis of the capabilities of oil refineries that consume crude oil in this region is given. The possibilities of enterprises providing reserve capacities of oil energy resources are considered. Based on the last decade data for the oil consumption and refining in the countries of the region, the tendencies of development of supply chains for the oil industry in the south of Europe are being investigated. The main regions of crude oil consumption are outlined, the prospects for the development of oil production in the countries of southeast Europe are shown. The presented analysis makes it possible to identify the most significant areas of southern Europe for the implementation of oil supply chains in the region, to build the most efficient cargo flows for shippers.

ABSTRACT

Supply chain management is one of the main sources for competitor advantages. Market environment claims more and more requirements for its participants, increasing logistics efficiency in particular. Diminution of costs is the main stream of optimization. Wherein reducing of logistics costs, and as a result, increasing enterprise competitiveness, can be achieved due efficient logistics.

The growing interest in increasing supply chain efficiency claims the higher requirements to assessment system of logistics. This is due to logistics methodology, which allows integrating different aspects of economic knowledge in order to develop new scientific ideas within material, financial, service and information flows. That provides the increase of supply chain and optimization of flow distribution insuring social impact and ecological requirements. 

The article contains methodological approach, which allows including transport indicators to total logistics costs model. Developed equations provide the ability to estimate dependence between transports operations on TLC (total logistics costs) on the base of integrated method of economic analyses.

Developed methodology is supposed to be used for analyses of dependency between transportation costs and TLC; and dependence between production indexes and transportation costs.

ABSTRACT

The purpose of this paper is to focus on theoretical and methodological aspects of horizontal cooperation in transportation. The relevance of the study is related to the search of additional sources for cost reduction in today's Russian economy,characterized by declining GDP and high inflation. Raw materials price rise, on the one hand, and the decline in real incomes, on the other, poses a problem of efficiency increase to the producers. According to the author, one of the most promising methods to reduce logistics costs in the current economic environment is horizontal cooperation. The paper proposes a simplified scheme of the feasibility evaluation of horizontal cooperation in transportation at the design stage.Based on modeling in Mathcad the author analyzes the feasibility of cooperation for each participant.The article also proposes a scheme, which is one of the possible variants of participants interaction in terms of horizontal cooperation. In concluding, the author suggests further development of the proposed methods of evaluating the feasibility of horizontal cooperation in transportation and the scheme of interaction of all participants.
