Optimization of goods transport for multimodal logistic platforms

Thesis

Jan 2021

Said Ahmed

In recent years, environmental issues are highly associated with the transport industry, modes of goods transport become more than contribution as largest between other sectors. Despite the benefits of intermodal transport, it still has negative impacts, which are associated with emission. However, pollution has become interesting between academic and industrial sectors. Thus, to mitigate the negative impacts caused by goods transport, that gains more and more relevance in the logistics domain. To meet these issue and challenges, to identify the contributions that green logistics to the optimization of freight transport, the increase the efficiency of the multimodal transport platform related optimization operations.The optimal operating of container transport is particularly important where goods transport in an environmentally way can be achieved by combining different modes of transport and coordinating activities such as finding the shortest path. In the multimodal container transport system, the selection of the transport mode and route has a large effect on the transport container transport process. In this thesis, to organize multimodal transport in a more efficient manner the container routing factor is considered along with the path factor of transport mode. The influence of the uncertain characteristics of the node operation on the transport mode and route choice in the process of converting the transport mode from containerized multimodal transport is studied. To minimize the total cost, an integer mixed programming model with time constraints is introduced. The graphical transformation is used to transform the problem into the shortest path model with random characteristics and transport time constraints in the node operations. By verifying and analyzing the results, the path obtained is acceptable from a cost and time perspective. Thus, this reducing traffic congestion and minimizing emissions. In the context of traffic congestion and emissions reduction, in this thesis a platoon technology is proposed to improve to reduce fuel consumption, road flexibility and optimize container transport operations. In this thesis, a ropeway system for the transport of small-scale goods is proposed and analyzed to reduce the traffic congestion within the urban area.The research concluded to optimization multi-modal transport platforms aims to reduce negative impacts on the environment and maximize profitability maximizing the services offered that minimize the total transportation cost as well as minimize the transportation time between each pair of Origin-Destination (O-D) nodes in the transport network. This work also contributes to reducing carbon dioxide emissions by decreasing consumption fuels and reducing operating costs. Based on this work, more effective and efficient container transport platforms can be achieved. This thesis introduces the theoretical base of optimal of multi-modal transport which can integration between different modes. Meanwhile, it contributes to logistics of multi/inter-modal transport efficiency.

Technological advances in transport of the 20th century include aeroplanes, human spaceflight and Moon landings, submarines, and magnetic levitation trains. In the fast-paced world of technology, the achievements of previous centuries are often forgotten. One of the examples of human ingenuity is the funicular railway. Its technology has hardly changed over the years. Using a simple pulley system, passengers and freight are still lifted steep slopes with minimal energy consumption. This demonstrates the lasting value of simple solutions and engineering intelligence. The article discusses the world’s funiculars and their design characteristics. A correlation analysis for the number of funiculars per country (N) and the country mountainousness index (M) has been carried out. 3 types of regression models have been developed and their determination and correlation coefficients have been calculated. The highest correlation coefficient values are for quadratic and linear mathematical models. The critical values of the correlation coefficients were calculated and compared with the correlation coefficients obtained from the study. For all 36 countries, the correlation coefficient for N and M variables is above the critical value only when a quadratic regression model is used. The correlation coefficients for all models are above the critical value for the 15 economically advanced and tourism-developing countries. The study shows that the number of cable cars in economically developed countries is more strongly correlated with the degree of mountainousness of the country in question.

Transport sector bears a significant share of responsibility for today’s society environmental issues. In this context, transport ought to include sustainable design principles in the early stages of development of each project. The present work examines an alternative proposal for Metropolitan Athens urban transport, introducing an innovative solution that has recently emerged, urban cable cars. Through literature study and the review of other cities’ best practices, cable cars’ technical characteristics as well as favourable and limiting factors are analysed. A new cable car line is proposed as a partial alternative to line 4 of the Athens metro, which construction has been announced to begin soon. The area of interest covers Zografou and Kaisariani Municipalities, located just a throw stone away from the center of Athens. Comparison factors include capacity, travel time, accessibility, safety, construction time and cost, operating and maintenance costs, environmental impacts, social acceptance and travel quality. Results indicate that cable cars provide sufficient capacity for the specific area offering many environmental advantages and also better coverage, lower cost (both construction and maintenance), lower energy consumption and better travel quality. On the other hand, Athens metro line 4 is evaluated as over-designed according to the expected ridership. As the latest developments in technology show, cable cars are sustainable means of transport with great potential within the urban fabric, under certain circumstances. The contribution of this work relies on revealing alternative solutions to cities’ transit problems, which in terms of environmental design can be resolved without the need to invest in large-scale projects such as metros.

Aerial ropeway system — feasibility study in Doha, Qatar

Article

Jan 2021

Shahram Tahmasseby

Aerial ropeway systems, also called gondolas and aerial cable cars, are amongst driverless transportation modes, which are progressively drawing the attention in promoting tourism. Aerial ropeway systems have been operated in touristic spots e.g., over lakes, rivers, and hilly lands in several countries. Passengers can enjoy a view from the above and experience a stress-free and reliable trip. Furthermore, those systems can be exploited as a public transportation in urbanized and populated regions. The objective of this article is to investigate the viability of implementing a gondola line flying over Doha Bay in Qatar as a tourist attraction from the marketing, economic, and environmental point of view. In this study, the associated costs (capital, maintenance, and operating) of implementing a monocable detachable gondola technology(MDG) are estimated using international best practices in the world. The economic analysis outcome demonstrates that the revenues generated from the fares could counterweigh the required capital investment as well as operating and maintenance costs and hence the proposed gondola could be economically attractive for investors. Moreover, no significant negative impacts and footprint on the environment are anticipated at the exploitation phase of the gondola.
