Over the last thirty years, intermodal freight transportation has been a constantly expanding sector. The vast increase of freight volumes contributes to the increase of various issues in the freight corridors as well as the urban environment. The deterioration of congestion in the urban environment and the increase on freight movements on the highways have resulted in the increase of emissions. For this reason, new policies and regulations are put forth to address the environmental effects of freight transportation. This study deals with the intermodal freight network design problem from the shipping company's perspective, aiming to simultaneously minimize emission levels and cost of freight transportation. We propose a mathematical model for optimizing the design of an intermodal freight network and the location of intermodal hubs between the origins and the destinations, under delivery time constraints. The goal is to identify the mode choice patterns considering transport cost and emissions, and the effects of new emission regulations on network costs. We consider a network with marine terminals as the origins, inland intermodal terminals as the hubs, and fulfillment centers as the destinations. Numerical experiments highlight that the proposed model can provide useful insights to the shipper. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2020. / FAU Electronic Theses and Dissertations Collection

Freight transportation changes in the region of Stockholm lead municipalities to the need of finding ways to maintain and empower their current logistics role in the area. These changes are the operation of the future freight port in Norvik near Nynäshamn, the expansion of Stockholm leading to new freight transportation networks, and the extension of the double track line southern to Västerhaninge station. Haninge municipality is willing to keep the interest of existing companies in its land alive and perhaps increase its’ attractiveness by constructing an extension of the terminal in Jordbro. But before proceeding to that step, the municipality wants to investigate whether companies are aware of these changes and furthermore if they have plans for changing their current goods transportation patterns. It is also interested in finding out the factors that companies consider as the most important when they take decisions about their goods transportation plan. That way the municipality knows what is important for companies and can adjust the supply of infrastructure to their demands. The main method used for data collection is designing and conducting a questionnaire and for data analysis it is multi-criteria analysis (MCA). The questionnaire also includes questions about the nature of the company and the current ways of goods transportation. Although the number of responders is quite low, some general conclusions could be made. There are two alternatives competing and multi-criteria analysis leads to the selection of the most suitable one. There are several limitations and assumptions which can be overcome by further future research.

The Swedish railway industry faces a predicted increase in demand, a demand shift in each railway product, new noise regulation, and the problem with attaining the right personnel. This creates new operating conditions that railway operators must adapt to. The planning process for allocating empty-wagons from one geographical area to another to fulfill customer demand is manually performed by three experienced Wagon Managers after the discontinuation of a fully automatic system called New VADIS. Green Cargo needs to streamline operations through a standardized empty-wagon allocation process to increase delivery precision, the utilization of the wagon fleet, and to promote cost-efficiency. The thesis will evaluate Green Cargo’s usage of wagons, provide a framework for how to standardize the allocation process, discuss benefits of wagon fleet rationalization, and expand upon the current method to eliminate flaws and internal waste. Literature reviews relating to the New VADIS project, intermodal load unit assignment, and transport fleet standardization were reviewed to provide the theoretical basis of the study. An evaluation of current KPIs resulted in the introduction of the Wagon Fleet Scorecard. Interviews with representatives from the Customer Service and Operations Center departments at Green Cargo formed the basis for necessary operative conditions needed to ensure the success of a future automatic allocation system. An attempt at solving the intermodal demand translation flaw of New VADIS was done through a new mixed-integer-linear programming optimization model for optimal loading of load units on ten intermodal wagon types. The model was evaluated on real-life production data from three intermodal terminals resulting in a significantly better assignment compared to the manual process, with an 11.26% shorter cumulative train length and 10.44% less loaded wagons. An indirect effect was the reduction of the cumulative tare weight of the departing loaded wagons with 11.49%. A new standardized process is presented that includes an operative implementation of the mathematical model using a common Visual Loading Plan. Furthermore, new allocation principles were formulated to maximize wagon capacity and fleet utilization as well as minimize allocation costs. The results indicate benefits towards Green Cargo’s continuous work with sustainable business practices. The proposed process results in a 1.5% reduction of Green Cargo’s total annual Scope 2 CO2 emissions through reduced energy consumption. It gives potential for extra revenue and reduces lean wastes from overproduction, unnecessary transports, extra processing, and waiting by providing better utilization of train capacities. It also results in enhanced social sustainability during loading operations at terminals by decreasing risk of human error, decreasing risks of wagon derailment, and by providing better conditions for terminal personnel to ensure proper load safety. / Den svenska järnvägsindustrin står inför en förutspådd efterfrågansökning, en efterfrågeförskjutning av varje järnvägsprodukt, ny bullerreglering och problem med att anställa personal med rätt kompetens. Detta skapar nya operativa förutsättningar som svenska järnvägsoperatörer måste anpassa sig till. Planeringsprocessen för att allokera tomma vagnar från ett överskottsområde till ett underskottsområde för att realisera kunders transportbehov utförs manuellt av tre erfarna Vagnledare, efter att det automatiserade systemet Nya VADIS avvecklades. Green Cargo behöver effektivisera verksamheten genom en standardiserad vagnförsörjningsprocess för att öka leveransprecisionen, nyttjandet av vagnsflottan och för att främja kostnadseffektivitet. Examensarbetet utvärderar Green Cargos användning av vagnar, tillhandahåller ett ramverk för hur vagnförsörjningsprocessen kan standardiseras, diskuterar fördelarna med en rationalisering av vagnflottan samt utökar den nuvarande metoden för att eliminera brister och internt slöseri. Litteraturgenomgångar relaterade till Nya VADIS-projektet, optimal lastning av intermodala lastbärare och standardisering av vagnflottan utfördes för att ge den teoretiska grunden för examensarbetet. En utvärdering av aktuella nyckeltal resulterade i skapandet av ett Wagon Fleet Scorecard. Intervjuer med representanter från avdelningarna Kundservice och Driftcenter på Green Cargo utgjorde grunden för nödvändiga operativa förutsättningar för att säkerställa framgången för ett framtida automatiskt vagnförsörjningssystem. Ett försök att lösa bristerna i den intermodal efterfrågeöversättningen i Nya VADIS genomfördes genom en ny linjär heltalsoptimeringsmodell för optimal lastning av lastbärare på tio intermodala vagntyper. Modellen utvärderades på verkliga produktionsdata från tre intermodala terminaler vilket resulterade i en betydligt mer optimal lastning jämfört med den manuella processen, med 11,26 % kortare ackumulerad tåglängd och 10,44 % färre lastade vagnar. En indirekt effekt var minskningen av den ackumulerade egenvikten av de avgående lastade vagnarna med 11,49 %. En ny standardiserad process presenteras som inkluderar en operativ implementering av den matematiska modellen med hjälp av en gemensam Visual Loading Plan. Vidare formulerades nya vagnstyrningsprinciper för att maximera nyttjandet av vagnars kapacitet, hela vagnflottans nyttjande samt minimera allokeringskostnaderna. Resultaten indikerar fördelar för Green Cargos kontinuerliga arbete med hållbara affärsmetoder. Den föreslagna processen innebär en 1,5 % minskning av Green Cargos totala årliga Scope 2 CO2 utsläpp genom minskad energiförbrukning. Det ger potential för extra intäkter och minskar lean slöserierna överproduktion, onödiga transporter, överarbete och väntan genom bättre nyttjande av tågkapaciteten. Det resulterar även i förbättrad social hållbarhet under lastning vid terminaler genom att minska risken för mänskliga fel, minska riskerna för urspårning av vagnar samt skapa bättre förutsättningar för terminalpersonal att säkerställa god lastsäkring.

A well-functioning transport system that can ensure efficient distribution is an important part of a mass-producing company. This is also the case for Holmen Paper Braviken, a paper mill with a widespread market base. Both today and historically, a large market share has been found in Europe, where a large proportion of the paper produced has been transported by truck and boat. In recent times, the demand for container transports has become higher as a result of sales in increasingly widespread markets. It is a trend that is forecasted to continue and to ensure that increased volumes henceforth still can be transported, Holmen Paper Braviken's current container transport solution has become interesting to investigate. In this study, the current process for container transports is examined as an outset and basis for identifying a possible solution that in the long term can facilitate a suitable development. It is clear that the current process for container transport is standardized with few adaptable possibilities but is well-functioning under the present conditions. However, hard endeavors are needed in specific periods due to high variations in volumes, which suggests a need to be flexible in adjustments. Furthermore, a container warehouse was identified as a possible development for the existing process. A container warehouse can lead to higher flexibility in transport activities by enabling the possibility to allocate and plan transports and resources to a greater extent. Since loading of containers is made possible when the undertakings are low, which can ease coming periods where there is a spike in demand. Therefore, loading operations can be spread out better over time and resources can more easily be redistributed based on the existing conditions of demand.   However, the introduction of a container warehouse is currently not seen as a feasible change since it involves significant investments and risks. If, on the other hand, the development on the market continues according to the current pattern, said investment will become a more and more reasonable solution. Since increasingly higher demands will be placed on flexible container transports, which would warrant a container warehouse to a higher degree. / Ett välfungerande transportsystem som kan säkerställa en effektiv distribution är en viktig del i ett massproducerande företag. Så är även fallet för Holmen Paper Braviken, ett pappersbruk med en spridd marknadsbas. Både idag och historiskt har en stor marknadsandel befunnit sig inom Europa där en stor andel av det producerade pappret transporterats med lastbil och båt. Under senare tid har dock efterfrågan på containertransporter blivit högre till följd av försäljning på allt mer spridda marknader. Det är en trend som prognostiserats fortsätta och för att säkerställa att ökande volymer fortsatt kan hanteras har Holmen Paper Bravikens nuvarande transportlösning för container blivit intressant att undersöka. Som utgångsläge i den här studien undersöktes den nuvarande processen för containertransporter för att identifiera en eventuell lösning som på sikt kan underlätta för den aktuella händelseutvecklingen. Det framgår att nuvarande process för containertransporter är standardiserad och väl fungerande under dagens förutsättningar men med få anpassningsmöjligheter. I perioder förekommer det ansträngningar på nuvarande system, främst baserat på höga variationer i volymer, vilket ställer krav på en flexibel anpassningsförmåga. Vidare identifierades ett containerlager som en tänkbar utveckling till den befintliga processen. Ett containerlager kan leda till en högre flexibilitet i transportaktiviteter genom att fördela om resurser och i högre utsträckning möjliggöra långsiktig planering av transporter. Eftersom förlastning av containrar är möjligt vid låg beläggning kan man underlätta för kommande tidsperioder med hög beläggning. Det innebär att beläggningen kan jämnas ut och resurser kan i perioder enklare fördelas om efter givet tillstånd i beläggning. Införandet av ett containerlager ses i dagsläget däremot inte som en genomförbar förändring eftersom det innebär betydande investeringar och risker. Om utvecklingen på marknaden däremot fortsätter enligt nuvarande mönster kommer sagda investering bli mer och mer aktuell. Då kommer allt högre krav ställas på flexibla containertransporter där ett införande av ett containerlager skulle kunna bli berättigat.

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.

Este trabalho está voltado à avaliação dos problemas do transporte intermodal sob efeito de restrições sazonais que, usualmente, não são consideradas na fase de planejamento e dimensionamento da frota. E, considerando a sobreposição de dois fatores sazonais restritivos ao longo da cadeia de transportes - a variação na produção de grãos ao longo do ano e a sazonalidade das cotas de nível d\'água nas hidrovias -, um modelo de simulação de eventos discretos mostra as impedâncias sofridas no sistema pela junção de fatores restritivos bem fortes. É possível avaliar o impacto dessas restrições não só no nível de utilização dos silos intermediários e silagem do porto, mas também no número de veículos necessários para fazer o transporte de commodities na região Centro-Oeste do Brasil. Em um sistema de transporte composto pelos modais rodoviário, hidroviário e marítimo, no qual o modelo de simulação abrange desde a produção nas fazendas, passando pelo transporte de caminhão até os armazéns intermediários, posteriormente com o transporte fluvial com destino ao porto para exportação. O presente estudo traz uma série de comparações entre cenários para avaliação dos gargalos existentes neste sistema de transporte intermodal, especialmente avaliando cenários com e sem as restrições sazonais, assim como análises de sensibilidade de performance de equipamentos de carregamento e descarregamento, nos quais a frota e os estoques necessários são substancialmente diferentes se a sazonalidade não for considerada. / This work focuses on the evaluation of the intermodal transport problems under the influence of seasonal constraints that are not usually considered on the phase of planning and sizing the fleet. Considering the superposition of two different seasonal factors along the transportation chain - first one the variation on grain production and the second one the level of water in the waterways throughout the year -, a discrete event simulation model was built to show the real effects of those constraints in the grain supply chain. So, it is possible to evaluate the impact of those constraints not only on the usage level of storages in this system, but also the number of vehicles required to transport this commodities from the Midwest of Brazil to the port. In a complex multimodal transportation system, the simulation model in this work includes roadways, waterways and seaways to transport all the cargo from farms to the final costumer. This study is composed by a number of scenarios to evaluate the bottlenecks in this intermodal transportation system, specially analyzing scenarios with and without seasonal constraints, as well as analysis of sensitivity of performance of equipment of loading and unloading, in which the fleet and the required stocks are substantially different if seasonality is not considered. In other words, it is possible to evaluate the risks involved when managers are making decisions if they do not take in consideration any of those seasonal constraints.

Following an increased transport activity, higher rates of intermodal transportation is seen as a possible way to a more sustainable transportation industry. Efficient and digitalized communication flows between actors can lead to improved flexibility and reliability, thus contributing to a more competitive service and higher utilization of intermodal transportation. However, as of today, the industry is experiencing barriers regarding digitalization. The purpose of this study is to investigate communication flows between intermodal transportation actors and explore the potential of digital transformation to increase utilization of intermodal transportation. The study includes a mapping of communication flows at Stockholm Norvik Port as well as an analysis of barriers and development. The mapping is presented as two figures, one for import of goods and one for export of goods. The figures show the container moves and the type of communication between actors. Based on current state and qualitative data collected through interviews, barriers and developments of communication flows are identified. The study shows that communication flows are still characterized by manual processes. Automating communication flows would reduce the number of human errors and inefficiencies, leading to improved reliability and flexibility within the system. The barriers found to hamper digitalization are mainly related to the themes of low willingness, size of investment, system integration, data security, and a lack of cooperation between actors. Implementing new technologies will not be utilized effectively unless all actors adapt. The study identifies an overall low digital maturity among the actors. When discussing technological developments, the actors show reliance on current business models, limiting the way technologies are developed and implemented, leading to risk of missing potential value. / En ökad nyttjandegrad av intermodal transport ses som en potentiell lösning till de hållbarhetsproblem som kommer av en ökad transportaktivitet. Effektiva och digitaliserade kommunikationsflöden mellan aktörer kan leda till förbättrad reliabilitet och flexibilitet och därmed bidra till en mer konkurrenskraftig tjänst och högre nyttjandegrad av intermodal transport. I dagsläget upplever dock branschen barriärer gällande digitalisering. Syftet med den här studien är att undersöka kommunikationsflöden mellan intermodala transportaktörer och utforska vilken potential digital transformation har för att öka nyttjandegraden av intermodal transport. Studien består av en kartläggning av kommunikationsflöden kring Stockholm Norvik Hamn och en analys av barriärer och utvecklingspunkter. Kartläggningen presenteras som två figurer, där den ena visar importflöden och den andra exportflöden. I figurerna visas hur containrarna förflyttas och vilka kommunikationssätt som används mellan aktörerna. Baserat på nuläget och data insamlad genom kvalitativa intervjuer är barriärer och utvecklingspunkter identifierade. Studien visar att kommunikationsflödena fortfarande till stor grad karaktäriseras av manuella processer. Genom att automatisera kommunikationsflödena skulle man kunna minska antalet fel till följd av mänskliga faktorer och ineffektiviteter, vilket skulle leda till förbättrad reliabilitet och flexibilitet i systemet. De barriärer som hindrar digitalisering är i huvudsak relaterade till temana låg vilja, investeringsstorlek, systemintegration, datasäkerhet och brist på samarbete mellan aktörer. Implementering av nya teknologier kommer inte att användas effektivt om inte alla aktörer anpassar sig. Studien identifierar en genomgående låg digital mognad för aktörerna, vilket tydliggörs genom hur de visar tilltro till nuvarande affärsmodeller. Detta begränsar hur teknologierna utvecklas och implementeras, vilket leder till att de riskerar att missa potentiellt värde.
