This vehicle runs in vacuum tubes at high speed, which is a transport concept commonly referred to as Hyperloop. In this case, Hyperloop is adapted for freight containers. \u0000 \u0000First, the main characteristics of the vehicle have been defined. These features conceptually define the freight Hyperloop studied, which does not include a compressor and levitates on magnets. \u0000 \u0000After this conceptual development, the defined Hyperloop is analyzed. For this analysis it was necessary to establish variables for the different aspects: Kantrowitz limit, aerodynamics, transportation, energy consumption, etc. These variables were employed to set parametric equations thereafter. Some of these formulae were extracted from previous theoretical works, while others are based on physical principles and others such as the capacity and energy indices are more practical. \u0000 \u0000Later, the simulation of the transport capacity has been performed. The computer program Engineering Equation Solver Professional V9.457-3D (EES) has been used to process the equations, create parametric tables and plots and obtain the final results. Prior to the simulation, input data were entered. These data come from references, calculations or optimizations developed by the authors in a previous work. The simulation allows choosing the number of containers, operating speed and tube length, primarily basing on energy and capacity indices, though auxiliary results as Kantrowitz limit results are needed as well. \u0000 \u0000Lastly, the optimal number of containers, operating speed and tube length were introduced in EES and EES yielded the definitive values of all of the output variables. These values constitute a pre-design of the train and are discussed at the end of the work. Further works that could originate from this one are proposed in this discussion.","PeriodicalId":177078,"journal":{"name":"TransportRN: Other International Trade & Freight Distribution (Topic)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126695562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Facilitating trade will help lower trade development costs as well as improve economic development and enhance economic benefits for emerging economies at a time when imports and exports are sent in and out across borders several times in the form of intermediate and final products. Not only that, globalization is being accelerated, which in turn increases competitiveness and this makes logistics one of the key factors when it comes to international trade. Highly efficient logistics services promote product movement, ensure product safety and delivery speed, and reduce trade costs between countries. The purpose of this study is, by using the LPI indices based on gravity model estimates, to analyze the impact of each LPI component on trade with the 20 biggest exporting countries of Northeast Asian countries — Korea, Japan, and China — which account for 19.05% of global exports.<br><br>Design/methodology – Also, this study statistically analyzes the impact of trade on Northeast Asian countries’ top 20 exporting countries, using the LPI indices relevant to Trade Facilitation based on the gravity model estimates.<br><br>Findings – As a result, it was turned out that the distance, GDP, and the LPI components have relevant impact on the trade exports of all three countries but demonstrated little relation to the demographic perspective.<br><br>Originality/value – The study also found we can increase the trade volume by improving three countries’ trade partners’ LPI indices since Korea, Japan, and China share most of their 20 biggest trade partners.","PeriodicalId":177078,"journal":{"name":"TransportRN: Other International Trade & Freight Distribution (Topic)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133546473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It also studies the effect of shipping knowledge and its absorptive capacity on the logistical value creation for customer satisfaction. An online survey was conducted to acquire responses from shipping companies such as freight forwarders, vessel liners, and logistic companies. Multiple regression tests were run to analyze the significance of shipping knowledge and its absorptive capacity for the creation of logistical value to provide end to end solution to the customer. The reliability test was executed, and the findings indicated that a high level of shipping knowledge has a positive impact on the logistical value of shipping companies. This study will enable 3PL firms to stay competitive in the market coping up with the rapid changes and tapping on to the untouched doors of some of the leading brands / customers in Pakistan with a variety of solutions.","PeriodicalId":177078,"journal":{"name":"TransportRN: Other International Trade & Freight Distribution (Topic)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114565200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Economic Importance of Belgian Transport Logistics","authors":"F. Lagneaux","doi":"10.2139/ssrn.1685846","DOIUrl":"https://doi.org/10.2139/ssrn.1685846","url":null,"abstract":"This paper is a publication issued by the Microeconomic Analysis service of the National Bank of Belgium. This is the outcome of a first research project on the Belgian transport logistics sectors. In the past few years, the logistics business has turned out to play a significant part in wealth creation in our country, whose economy is driven by services. This study can be seen as an extension of Working Paper No. 115 on Belgian ports, issued in May 2007, as the activities under review are closely tied to transport in general and maritime transport in particular. Considering that this is a first attempt to estimate the economic importance of Belgian transport logistics, it was decided to favour a sectoral approach, by focusing on some freight transport logistics sectors clearly defined in the NACE classification. The impact is presented in two parts: the direct effects and the indirect effects. Furthermore, a short analysis is provided about the economic impact of other activities, such as in-house logistics and European distribution centres. An overview of some developments per sub-sector is provided for the period 2000 - 2005, with the emphasis on 2005. The core of the analysis, which is statistical and therefore not based on a survey, looks more specifically into developments in terms of value added, employment, investment and the financial situation of the companies concerned. A first estimate of developments over the 2005 - 2006 period is also provided for value added and employment. Annual accounts data from the Central Balance Sheet Office are used for the calculation of direct effects, the study of financial ratios and analysis of the social balance sheet. Also worth mentioning is that the indirect effects of the activities concerned have been estimated in terms of value added and employment, on the basis of data from the NAI (National Accounts Institute). A comprehensive analysis of the linkages between the sectors under review and the other Belgian sectors is presented. The activities under review accounted for no less than 3.1 p.c. of Belgian GDP and 3.4 p.c. of the country's domestic employment in 2005. Including indirect effects, these percentages respectively amounted to 5 and 5.3 p.c. in the same year. Taking some survey data into account, the overall impact would reach roughly 8 p.c. of the Belgian economy, if transport logistics business provided by external branches on the one hand and in-house transport logistics on the other were added to these above-mentioned sectoral percentages. This report provides a comprehensive account of these issues, giving information per economic sector.","PeriodicalId":177078,"journal":{"name":"TransportRN: Other International Trade & Freight Distribution (Topic)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130135184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
