Totalkostnadsmodell för distributionsnätverk med internationella containertransporter

Purpose ? The purpose of this thesis is to develop a total cost model for container transports and create a tool that calculates a suitable transport quantity from an economic view, which fulfills the demands on delivery service. To achieve this purpose the following questions will be answered:Which costs are affected by the decision between the two transport alternatives LCL and FCL?   How does the decision of sending product LCL or FCL influence the delivery service?  How can a tool be constructed to simplify the decision-making process regarding the choice of sending products LCL or FCL?  Method ? A total cost model was developed. This model is supported from existing literature.

Ökad användning av biodrivmedel i vägtransportsektorn : en styrmedelsanalys

The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010. More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.

Samverkan på Järnvägen : Samverkan för arbete med Förebyggande Underhåll

Under litteraturstudierna fick författarna en uppfattning om att järnvägsbranschen är präglad av en hel del problematik som visat sig i ett flertal brister. Flera större omorganiseringar hade skapat en bransch med otydliga ansvarsgränser och otydliga roller med en mängd utdragna rättsliga tvister mellan beställare och entreprenörer som följd. Stämningen beskrevs som dyster och kompromisser mellan järnvägsaktörer förekom inte i den mån som behövdes, utan aktörerna tänkte mest på sin egen verksamhet. En ändring behövdes.Rapporten är begränsad till tre nyckelaktörer med koppling till järnvägsunderhåll: beställare, entreprenör och trafikutövare. Fokus har lagts på det alltför förekommande avhjälpande underhållet, som visar sig i form av trafikstörningar och trafikstopp.

En jämförelse av energiåtgång och emissioner för olika persontransportslösningar i Stockholm stad

This master thesis sets out to compare the different public transport modes in Stockholm city.Both energy consumption and air pollution are compared. The chosen transport methods are car,bus and metro.Traditionally the rail industry has had environmental arguments as a strong competitiveadvantage when it comes to passenger transportation. However, in recent years the automotiveindustry has been getting more positive media attention regarding environmental issues, forexample Roger Kemp?s statement that the car is the most environmental friendly passengertransportation mode in the UK. This study will show the environmental advantages of railwaytraffic in cities.The energy sources of the world are not endless and the use of the different sources affects theenvironment in different ways.

Däck-mark Interaktion hos skogsmaskiner

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

Vilka faktorer inverkar vid valet av transportföretag? : En fallstudie om företagskunders resonemang och prioriteringar vid köp av transporttjänster och val av transportföretag.

During the last couple of years the focus for many businesses have moved from just being price oriented to include such factors as quality, flexibility, service, delivery precision and environmentally friendliness. The shift in viewpoint arises from the increasingly competition on the market and the hard economic atmosphere. It has become more important to differentiate the company and its products to be able to increase market share. The purpose with this master?s thesis was to get a better understanding on how companies (customer to DHL) are reasoning and prioritizing when choosing Swedish carriers.

KOLLEKTIVTRAFIKENS GEOGRAFISKA VARIATIONER I TID OCH KOSTNAD ? HUR PÅVERKAR DETTA BOSTADSPRISERNA? : Fallstudie Uppsala län med pendlingsomland

The distance between home and work has increased in recent decades. By the development of infrastructure and public transport, jobs farther from home have become more accessible and this development has in turn increased commuting. Commuting travellers often pass over administrative boundaries which often serve as borders for public transport pricing. Also the market control prices. Research shows that travel times and costs significantly affect commuting choice.

Fordonsbestånd och nyregistreringar - en statistisk analys av regionala skillnader och strukturella faktorer

The official statistics on communication and transports in Sweden is administered by Statens Institut för kommunikationsanalys (SIKA). SIKA?s commission includes production of statistics on the Swedish vehicle fleet. These statistics provide important information tofinancial institutes, ministries, industry and mass media among others. Furthermore, the vehicle statistics include measures of comparison between different counties and municipalities.

Användning av rötrest från kombinerad etanol och biogasproduktion : en jämförelse mellan tre alternativ

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

Lokal etisk produktion ? är den globalt hållbar?

In modern society globalisation is a fact within all industries, the textile industry included. Due to improvement in areas such as logistics and communication international trade have developed fast. As changes occur rapidly on the global market and companies must adjust and revise their processes in order to stay competitive.Because of the global price reduction consumers around the world expect low-price products, which mean that the companies have to find new ways to produce in a cost-efficient way. To maximize profit most of the textile production is situated in low-cost countries due to its labour-intensive character. It is crucial for fashion companies to allocate their activities in their value-chain effectively in order to reduce lead-times.

Utveckling av temporär kulturutsällning

Den här rapporten utgör dokumentationen av ett examensarbete som genomfördes inom Kandidatpåbyggnadslinjen vid Jönköpings tekniska högskola. Inom det jubileumsår som Nässjö stad firar i samband med stadens 100-årsdag var det Nässjö Järnvägsmuseums mål att ta fram en temporär kulturutställning i en tågvagn, vilken ska stå vid Nässjö tågstation under jubileumsårets gång. Genom projektledare hos Nässjö kommun kom museet i kontakt med en designstudent från Jönköpings tekniska högskola, vilken erhöll uppgiften att utveckla den temporära kulturutställningen.Syftet med projektet var att undersöka hur en temporär kulturutställning kan se ut för att locka till sig besökare och intresse från önskade målgrupper. För att konkretisera syftet konkritiserades de till en frågeställning som handlade om hur temporära kulturutställningar och deras grafiska kommunikation kan te sig för att locka till sig önskade målgrupper. Därtill togs fyra konkreta målsättningar fram, vilka specificerade att projektet ska leda till designen av en utställning, tillhörande grafisk kommunikation, skyltning för Nässjö järnvägsmuseum samt ett kompendie där den grafiska kommunikationen visades upp.För att exemplifiera hur en temporär kulturutställning kan te sig och infria målsättningarna inleddes arbetet med undersökningar observationer och intervjuer vid olika kulturutställningar.

Korrelation mellan hållfasthet i kalkcementpelare och oförstärkt lera : En studie av sonderingar utförda på projekt BanaVäg i Väst

A today common soil reinforcement method is the installation of lime-cement columns. Lime-cement columns have been used since the 1970?s and have been a useful method for stabilizing soil at great depths. It is mostly used for stabilizing road and railway embankments because the method is economically viable and the columns are easy to install. The total costs for the installation of the lime-cement columns is dependent on the numbers of installed columns, what percentage of lime and cement that has been used and the pattern in which the columns has been installed.

Odefinierade platser i staden : med studie i Söderälje

The purpose of this master thesis is to attract attention to the undefined spaces of our urban landscape and emphasize the need of these spaces in the city. The different values of these spaces are here clearly presented so that they can be considered when real estate developers show a particular interest in any one of these undefined spaces. The term undefinied spaces can mean a lot of things. The spaces that I now choose to define as undefined spaces are neither planned nor designed. It could for instance be a piece of leftover land in between two residential areas, or as times change, a formerly planned area might be forgotten and left to its own.

Kalkyl för logistikkostnader; från leverantör till förbrukningsplats

The globalization that has occurred during the last few years has made it more important for companies to have a well-functioning logistics system. Customers demand more options, which lead to an increased flow that creates greater demand regarding packaging and transports. Diverse logistics costs are nowadays a substantial cost for many companies. Therefore, more effort is aimed at optimizing transportation to lower these costs.The purpose of this project is to create a user-friendly calculation of logistics costs that illustrates how the costs vary, depending on how the flow is structured. This is done by examining which aspects that affect the total logistics costs and by mapping which aspects that should be included in a calculation of the logistics costs.Literature studies have been carried out parallel with empirical studies at Scania's production unit, MC, in Oskarshamn.
