Designing a Rational Distribution Network for Trading Companies

Published Online: 27 Jun 2017
Page range: 181 - 193

Abstract

Abstract

This article considers the modern methods and approaches to design the company’s distribution network. The authors point out the relevance of this problem for the modern trading and manufacturing companies, give examples of the strategic goal setting of the company in the logistics network reorganization, and the benchmarks of possible economic effects of its conduction. The work reviews the scientific articles of contemporary American, European and Russian authors devoted to the approaches, concerning the implementation of projects for designing a distribution network, methods and models for its optimization. The article concludes that there is no single “language” and an approach to design the logistics networks, with a proper level of detail that takes into account the strategic features and industry specificity of the certain company. The authors propose an algorithm for designing a rational distribution network.

A Cloud Computing Model for Optimization of Transport Logistics Process

Published Online: 27 Jun 2017
Page range: 194 - 206

Abstract

Abstract

In any increasing competitive environment and even in companies; we must adopt a good logistic chain management policy which is the main objective to increase the overall gain by maximizing profits and minimizing costs, including manufacturing costs such as: transaction, transport, storage, etc. In this paper, we propose a cloud platform of this chain logistic for decision support; in fact, this decision must be made to adopt new strategy for cost optimization, besides, the decision-maker must have knowledge on the consequences of this new strategy. Our proposed cloud computing platform has a multilayer structure; this later is contained from a set of web services to provide a link between applications using different technologies; to enable sending; and receiving data through protocols, which should be understandable by everyone. The chain logistic is a process-oriented business; it’s used to evaluate logistics process costs, to propose optimal solutions and to evaluate these solutions before their application. As a scenario, we have formulated the problem for the delivery process, and we have proposed a modified Bin-packing algorithm to improve vehicles loading.

The Logistic of Empty Containers′ Return in the Liner-Shipping Network

Published Online: 27 Jun 2017
Page range: 207 - 219

Abstract

Abstract

The Maritime Transport is a favoured tool regarding the universal exchanges because it has gone through several evolutions. Indeed, the containerization is considered as one of the most remarkable improvements in the shipping. The containers are rented by shipping companies. However, these companies meet an empty container availability problem at some ports of Maritime Transport Network (MTN) to satisfy the demands of clients. The objective of this work is to solve the problem of the imbalance of the distribution of containers and look for empty containers at less cost to meet the demands of clients. As a result, the authors propose an application to represent the MTN, and provide a balanced distribution of containers. The work presented in this article is based on a heuristic method by neighbourhood. It allows the process of the clients' demands and transfers of full containers as well as the research of empty containers by optimizing the cost of theirs return.

Evolution of Traveller Experience Quality Perception in European Level Policy Documents and the Case Study for Siauliai

Published Online: 27 Jun 2017
Page range: 220 - 230

Abstract

Abstract

EU’s goal is to develop transport system which meets the economic, social and environmental requirements of society. Since first White paper on Transport in 1992 there was evolution of perception of quality and attributes of quality. The basic set of quality requirement is based on frequency, price, safety and security were dominating in 1992-2006, however since 2006 new attributes such as environment impact, and energy efficiency comes into force in European documents. However research case in Siauliai town show that it delays in user perception of quality.

On The Problem of Constructing Routes, Part I: Preface

Published Online: 27 Jun 2017
Page range: 231 - 233

Abstract

Abstract

This is a preface of the translation of the 1967 paper by Linis and Maksim, “On the problem of constructing routes” (in Russian) (in the Proceedings of the Institute of Civil Aviation Engineering, Issue 102, pp. 36-45). It marks 50-year to the deficit function (DF) model initially developed in this 1967 work; the DF model then paved the way to further research of vehicle-fleet management in terms of optimal routing and scheduling. The merit of this translation is to describe the roots of the DF modelling to enable further studies to emerge with more contributions.

On the Problem of Constructing Routes, Part II: Methodology and Numerical Example

Published Online: 27 Jun 2017
Page range: 234 - 239

Abstract

Abstract

We consider a periodic aviation schedule which is a finite collection of flights with given arrival/departure times. For this schedule, we solve the problem of finding the minimal number of aircrafts needed to carry out the flights. The crucial role in solving this problem is played by so-called deficit function (DFs) defined as the difference between departures and arrivals on interval [0,t] for each terminal.
