Logistika v ČR / Logistics in the Czech Republic

Štemberová, Kateřina January 2009 (has links)
The Master's Thesis analyzes a logistic background of the Czech Republic in the context of the recent economic crisis and its influence on the development of selected indicators of the logistic market. The objective of the Thesis is to evaluate the impact of these aspects on lo-gistic competitiveness of the Czech Republic in Central and Eastern Europe. The Thesis de-scribes the current situation of the European logistic market together with the main future development trends. The recent development on logistics and industrial property market is worked out in detail, including the changes in attractiveness of logistics locations and criteria influencing developers' activities. Subsequently the Thesis analyzes the situation in logistics and transport infrastructure, characterizes the freight transport and presents current options for their further development. The final part of the Thesis introduces options for education in logistics available in the Czech environment.

Impactos de regulações ambientais sobre o transporte de cargas no Brasil: uma análise para o transporte de soja / Impacts of environmental regulations on the freight transport in Brazil: an analysis for soybean transport

Ávila, Ednilson Sebastião de 12 April 2016 (has links)
O aumento da concentração de gases de efeito estufa na atmosfera levou a uma preocupação de como se reduzir as emissões destes gases. Desta preocupação surgiram instrumentos de regulação a fim de reduzir ou controlar os níveis de poluição. Dentro deste contexto, esta pesquisa analisou o setor de transportes de cargas, com ênfase no transporte de soja. No Brasil, o setor de transportes é um dos principais responsáveis pelas emissões de gases de efeito estufa provenientes da queima de combustíveis fósseis. No setor de transportes, as emissões diferem entre os modais, sendo que as ferrovias e hidrovias poluem menos que as rodovias. Desta forma, simulou-se por meio de um modelo de programação linear se a adoção de medidas regulatórias sobre as emissões de CO2 traria uma alteração no uso das ferrovias e hidrovias. Uma das constatações, ao se utilizar o modelo de Minimização de Fluxo de Custo Mínimo para o transporte de soja em 2013, foi que a capacidade de embarque nos terminais ferroviários e hidroviários desempenha um papel fundamental na redução das emissões de CO2. Se não houver capacidade suficiente, a adoção de uma taxa pode não provocar a redução das emissões. No caso do sistema de compra e crédito de carbono, seria necessária a compra de créditos de carbono, numa situação em que a capacidade de embarque nos terminais intermodais seja limitada. Verificou-se, ainda, que melhorias na infraestrutura podem desempenhar um papel mitigador das emissões. Um aumento da capacidade dos terminais ferroviários e hidroviários existentes, bem como o aumento da capacidade dos portos, pode provocar a redução das emissões de CO2. Se os projetos de expansão das ferrovias e hidrovias desenvolvidos por órgãos governamentais saírem do papel, pode-se chegar a uma redução de pouco mais de 50% das emissões de CO2. Consideraram-se ainda quais seriam os efeitos do aumento do uso de biodiesel como combustível e percebeu-se que seria possível obter reduções tanto das emissões quanto do custo de transporte. Efeitos semelhantes foram encontrados quando se simulou um aumento da eficiência energética. Por fim, percebeu-se nesta pesquisa que a adoção de uma taxa não traria tantos benefícios, econômicos e ambientais, quanto a melhoria da infraestrutura logística do país. / The increased concentration of greenhouse gases in the atmosphere has led to a concern of how to reduce emissions of these gases. From this concern, regulatory instruments were conceived in order to reduce or control pollution levels. Within this context, this research examined the freight transport sector, with emphasis on the soybean transport. In Brazil, the transportation sector is a major contributor to the greenhouse gas emissions from burning fossil fuels. In the transportation sector, emissions differ among transportation modes, with the railways and waterways polluting less than the highways. Thus, it is simulated by means of a linear programming model if the adoption of regulatory measures on CO2 emissions would bring a change in the use of railways and waterways. One of the findings, using the model of Minimum Cost Flow Minimization for soybean transport in 2013, was that the loading capacity on rail and waterway terminals plays a key role in reducing CO2 emissions. If there is an insufficient capacity, the adoption of a tax may not cause the reduction of emissions. In the case of the cap and trade system, this would require the purchase of carbon credits in a situation where the loading capacity in intermodal terminals is limited. It was found further that improvements in the infrastructure could play a mitigating role for emissions. An increase in capacity of existing rail and waterway terminals, as well as increasing the capacity of ports, can cause the reduction of CO2 emissions. If the expansion projects of railways and waterways developed by government agencies leave the paperwork, it can be reached a reduction of over 50% of CO2 emissions. It was still considered what would be the effects of increased use of biodiesel as fuel, being realized that it would be possible to obtain reductions in both emissions and the shipping cost. Similar effects were found when it was simulated an increase of energy efficiency. Finally, it was noted in this study that the adoption of a tax would not bring so many benefits, including the economic and environmental ones, to improve the country\'s logistics infrastructure.

Modelling the South African fresh fruit export supply chain

Ortmann, Frank Gerald 12 1900 (has links)
Thesis (MSc (Applied Mathematics))--University of Stellenbosch, 2005. / The process of modelling the fruit export infrastructure capacity of South Africa formed part of a larger project called the \Fruit Logistics Infrastructure Capacity Optimisation Study," which was coordinated by the Transportek division of the CSIR in Stellenbosch during the period August 2002 to March 2004. The aim of this project was to create efficiencies for, and enhance the competitiveness of, the South African fruit industry by improved usage of, and investment in, shared logistics infrastructure. After putting the size of the fruit industry into perspective, numerous aspects of the export process are considered in this thesis so as to be able to perform a comprehensive cost analysis of the export of fruit, including the cost of handling, cooling and transportation. The capacities of packhouses, cold stores and terminals are found and presented. This information, combined with fruit export volumes of 2003, then allow an estimation of the current utilisation of the South African ports with respect to fruit export.
