The sustained and stable growth of China’s market economy promotes the continuous improvement of transportation demand and puts forward higher requirements for transportation products. At present, as a new product, high-speed rail freight has played an important role in cold chain logistics and high-value-added transportation, which is of great significance to effectively reduce the pollution caused by road transportation and further promote the sustainable development of economy and logistics industry. In the previous study, we studied the organization optimization method of high-speed rail freight train operation scheme and the compilation method of high-speed rail freight train diagram based on the overall demand of freight transportation but did not consider the influence of different high-speed rail freight transportation products on the organization scheme. Therefore, in order to ensure the sustainable development of high-speed rail freight business, based on the demand of high-speed freight products (the freight product for short in the following text), this paper focuses on the optimization method of high-speed rail freight train organization scheme considering different demands. A two-stage freight demand analysis method considering customers’ choice intention and actual supply capacity was designed, comprehensively considering the relationship between operation cost and income, and a model based on different products in order to meet the needs of large-scale case solving was established. In addition, a column generation algorithm was designed. The computational results are encouraging and demonstrate the effectiveness of the model and solution method.

“…En otro estudio del sistema de transporte en Trolebús se realizó un análisis en el cual se identificó que se puede realizar una mejora del sistema actual empleando líneas normales, exprés, unidireccionales y bidireccionales (Torres et al, 2008). Este análisis debería realizarse tanto en el sistema Trolebús como en el sistema Ecovia y Metrovia existentes actualmente.…”

El presente artículo tiene como fin presentar el diseño de un sistema de evaluación del transporte público en Quito. Se propuso esta temática debido a que el sistema de transporte público en Quito y otras ciudades de Latinoamérica no ha sido planificado adecuadamente, lo cual provoca problemas en la calidad del servicio como altos tiempos de espera, incomodidad al desplazarse, inseguridad, entre otros aspectos. Con el objetivo de ofrecer un mejor servicio se propone el diseño de una aplicación móvil, mediante la cual los usuarios podrán evaluar el servicio otorgado y a su vez los transportistas y la Alcaldía del Distrito Metropolitano de Quito tendrán acceso a esta información mediante un portal web tal que se pueda ejercer un correcto control del servicio. Se desarrolló una planificación basada en la metodología PMBOK ya que al tratarse de un ente público se requiere mayor nivel de documentación y detalle en los procesos.

“…In interacting self avoiding walks on a 2D lattice with preferential attachment rules are applied to produce similar statistics to real world PTN. In Torres et al (2011) an optimisation model for line planning is discussed considering the competing interests in maintaining a quality service whilst minimising costs. In Yang et al (2011) PTN are grown a route for each time step using an ideal n-depth clique topology.…”

In this paper we investigate the topological and spatial features of public transport networks (PTN) within Great Britain. Networks investigated include London, Manchester, West Midlands, Bristol, national rail and coach networks during 2011. Using methods in complex network theory and statistical physics we are able to discriminate PTN with respect to their stability; which is the first of this kind for national networks. Taking advantage of various fractal properties we gain useful insights into the serviceable area of stations. Moreover, we investigate universal load dynamics of these systems. These features can be employed as key performance indicators in aid of further developing efficient and stable PTN.
