The paper considers some issues related to different approaches to select the preferred route; analysis is made of the methods and models of analytical description of it; also practical solutions to select the preferred route are analyzed here; the definitions of preferred route and the area of the subjective preferred route are given. The tasks laying the path of the preferred route and selective...
The importance of elaboration of an intelligent development system of the megalopolis transportation system is shown. Modern approaches to the development and intellectualization of transportation systems are reviewed. By using the logical-algorithmic language, a formal development of the system is carried out. Its external and internal structures are described.
Intermodal road-rail transportation Systems (IRRTS) is a typical complex giant system which is dilïîcult for traditional management approaches to form effective solutions with dynamic adaptability. In the physical world, simple equipment upgrading and transport optimization can't satisfy the demand of IRRTS for high efficiency and low cost. Thus, a framework of parallel IRRTS based on ACP approach...
Current trends of urbanization and growing economies bring with them rising levels of traffic congestion and city governments must recur to new strategies to deal with such problems. Multi-level distribution is an already-known strategy employed by businesses, and the classic formulation of the Two-Echelon Vehicle Routing Problem (2E-VRP) reflects the perspective of a single provider, without regarding...
The connectivity and accessibility of public transit network (PTN) catch an increasing interest by scholars. However, few of the existed researches take into account walking mode and biking mode when representing or analyzing the connectivity and accessibility of PTN. Actually, those mode plays an important role on PTN properties. Given that, this paper aims to investigate how the walking mode and...
The proposal of an intelligent logistics model that allows help the optimization of a Smart City is presented in this research, and thereby achieve reduce traffic accidents specifically those related to transport any type of product to generate energy. In addition, the problem of routing of vehicles (VRP) is the approach from which faces the problem of logistics, management and distribution of goods...
Logistics distribution center location problem is a hot topic nowadays. We choose a medium-sized city group to study in this paper. The improved artificial immune algorithm based on similarity vector distance selection is used for the logistics distribution center location problem. The algorithm uses the threshold value to restrict concentration calculation of two antibodies from two aspects which...
The Costa Rican Ministry of Science, Technology and Telecommunications (MICITT) promotes The Science and Technology Month. This is a yearly celebration aimed at bringing young students closer to science and technology. In 2016, the activity included events in six rural areas around the country. Laboratorio Experimental is a group for research and outreach in computer science education hosted by Instituto...
The residential load of existing consumers can be increased significantly due to large-scale purchase of household appliances with high-energy consumption; consequently, changing the expansion plans of electrical distribution networks. In this paper, a spatial-temporal model is proposed to estimate the load growth of distribution transformers owed for this kind of electrical appliances. In order to...
The study aims to research the effecting factors of the level of independent innovation ability in China, constructing innovation environment by the grey clustering model and build the national innovation capability evaluation index system, including the innovation input, innovation output and innovation potential of 4 indexes and 17 level two indexes. The related data of 26 countries was collected...
Probabilistic selling is a marketing strategy in which a multi-item seller provides buyer with an option to purchase for less by accepting an uncertainty risk in getting a random item from a set of multiple distinct items. However, previous studies on this strategy assume that no return is allowed, partly because return policy will shift part of the mentioned uncertainty risk back to the seller. Since...
The growing demand on service quality and trade volume of pharmaceutical logistics has continued to be highly concerned by the China Government. Driven by government's policies, logistics of pharmaceutical industry are able to deal with the problem of drug efficacy failure during the process of transportation by adopting intelligentized system. The aim of this study is to explore the key success factors...
This paper intends to find the critical success factors for smart green city logistics business in Fuzhou. We first investigate and collect the factors that impact the operations of smart green city logistics business. In order to acquire the experts’ assessments on the influence between each two factors, we invite the managers who serve in the top five logistics companies in Fujian and conduct expect...
The urban logistics industry agglomeration area ecosystem is an industrial ecosystem with such functions as self-organization, self-regulation and self-adaption. It is composed of enterprises and supporting institutions related to the city logistics industry chain. This paper analyzes the evolution mechanism of urban logistics industry agglomeration area ecosystem, and builds the evolution model by...
City logistics seeks to optimize the distribution of goods in urban areas by developing new business models. Such models are not only centered on cost reduction, but also account for reducing the negative impact resulting from city logistics activities. Therefore, environmental aspects or congestion are important factors as well. Through consolidation of goods of different shipper-consignee pairs,...
Interest in City Logistics has been increasing among scholars, the industry, local administrations and various stakeholders. In particular, a number of projects have been developing with the aim of overcoming the negative impact of urban parcel delivery and making it more efficient and sustainable, from both the operations and environmental standpoints. However, most of these initiatives are more...
Even though the first attempt to develop a vehicle-sharing system can be traced around 1950, only in the last decade it was possible to see an increase both in members and in service providers. This increase is mainly fostered by strong developments in the IT sector, which allow car-sharing companies to offer easier solutions to their members, such as vehicle localization and booking and electronic...
Ubiquitous real-time passenger information (URTPI) is state-of-the-art travel information for public transport passengers and an integral part of intelligent transport systems. URTPI enables travellers to access information before and during a journey. Passengers are offered information to make both pre-trip and en-route choices. The effectiveness of the information provision and the return on investments...
Passengers and freight mobility in urban areas represents an increasingly relevant component of modern city life. On one side, it fosters economic growth, but, on the other, it also generates high social costs. Congestion and pollution are two problems policy-makers want to curb adopting appropriate measures. The pervasive use of information and communication technology will contribute to the fuller...
This work focuses on wide-scale freight transportation logistics motivated by the sharp increase of on-line shopping stores and the upsurge of Internet as the most frequently utilized selling channel during the last decade. This huge ecosystem of one-click-away catalogs has ultimately unleashed the need for efficient algorithms aimed at properly scheduling the underlying transportation resources in...
