Co-distribución para logística urbana: análisis de experiencias internacionales

Population growth has been accompanied by an increase in the percentage of people living in urban centers in both developed and non-developed countries. These areas with high population density generate an increase in commercial activity, with urban freight transport being a key factor, as it provides the products marketed by its stores. However, market capillarity, strict time windows and lack of infrastructure cause this activity to be carried out inefficiently and therefore, at a high cost. Moreover, urban freight transportation affects other externalities such as contamination, noise and existing traffic congestion. Several authors have proposed co-distribution as a way to improve the distribution system and mitigate the problems mentioned above. This article aims to gather and analyze information on the different methods used in co-distribution in different parts of the world, supported by practical experiences. As a result, it is concluded that almost all articles published in this subject refer to the implementation of Urban Consolidation Centers, which, while mitigating several of the problems mentioned, they generally need support from the government to make them economically viable.El crecimiento en la población ha sido acompañado por un aumento en el porcentaje de las personas que habitan los centros urbanos, tanto en países desarrollados como no desarrollados. Estas zonas con alta densidad de población generan un aumento en la actividad comercial, siendo el transporte urbano de mercaderías un factor clave, ya que provee los productos comercializados por sus tiendas. Sin embargo, la capilaridad del mercado, estrictas ventanas horarias y falta de infraestructura provocan que esta actividad se realice de manera ineficiente y por lo tanto, a un costo elevado. Por otro lado, el transporte de mercaderías afecta otras externalidades como la contaminación, el ruido y la congestión de tránsito ya existente. Varios autores han investigado la co-distribución como una forma de mejorar el sistema de distribución urbana y mitigar los problemas anteriormente mencionados. Este artículo pretende recopilar y analizar la información sobre los diferentes métodos utilizados en co-distribución a nivel mundial con sustento en experiencias prácticas. Como resultado, se concluye que casi la totalidad de los artículos publicados en esta temática refieren a la implementación de Centros de Consolidación Urbanos (CCU), los cuales, si bien mitigan varios de los problemas mencionados, en general necesitan de apoyo por parte del gobierno para que sean económicamente viables

AIRO 2016. 46th Annual Conference of the Italian Operational Research Society. Emerging Advances in Logistics Systems Trieste, September 6-9, 2016 - Abstracts Book

The AIRO 2016 book of abstract collects the contributions from the conference participants. The AIRO 2016 Conference is a special occasion for the Italian Operations Research community, as AIRO annual conferences turn 46th edition in 2016. To reflect this special occasion, the Programme and Organizing Committee, chaired by Walter Ukovich, prepared a high quality Scientific Programme including the first initiative of AIRO Young, the new AIRO poster section that aims to promote the work of students, PhD students, and Postdocs with an interest in Operations Research. The Scientific Programme of the Conference offers a broad spectrum of contributions covering the variety of OR topics and research areas with an emphasis on “Emerging Advances in Logistics Systems”. The event aims at stimulating integration of existing methods and systems, fostering communication amongst different research groups, and laying the foundations for OR integrated research projects in the next decade. Distinct thematic sections follow the AIRO 2016 days starting by initial presentation of the objectives and features of the Conference. In addition three invited internationally known speakers will present Plenary Lectures, by Gianni Di Pillo, Frédéric Semet e Stefan Nickel, gathering AIRO 2016 participants together to offer key presentations on the latest advances and developments in OR’s research

Operational Research: Methods and Applications

Throughout its history, Operational Research has evolved to include a variety of methods, models and algorithms that have been applied to a diverse and wide range of contexts. This encyclopedic article consists of two main sections: methods and applications. The first aims to summarise the up-to-date knowledge and provide an overview of the state-of-the-art methods and key developments in the various subdomains of the field. The second offers a wide-ranging list of areas where Operational Research has been applied. The article is meant to be read in a nonlinear fashion. It should be used as a point of reference or first-port-of-call for a diverse pool of readers: academics, researchers, students, and practitioners. The entries within the methods and applications sections are presented in alphabetical order. The authors dedicate this paper to the 2023 Turkey/Syria earthquake victims. We sincerely hope that advances in OR will play a role towards minimising the pain and suffering caused by this and future catastrophes
