På väg mot ett hållbart resande? : En fallstudie kring den lokala kollektivtrafiken i Umeå tätort
Sustainability and the traffics impact on the environment have become increasingly central within spatial planning. For many years, planning has been focusing on building new roads - this has resulted in increased use of automobiles, which many believe is unsustainable in the longer term. Therefore, authorities at national, regional and local level want to increase the use of alternative transport modes ? such as walking, cycling and traveling by bus.The thesis intends to study if the Municipality of Umeå?s policies for sustainable development have led to an increased use of public transportation. The use of public transport in Umeå is also compared with developments at national level, in order to see if there are differences in the level and trend.
Terminallokalisering med tyngdpunktsberäkning och kostnadsanalys
The Kedertruss is the loadbearing part in the Keder weatherprotectionsystem and it has been analyzed concerning its loadbearing capacity. The Kedertruss is produced and manufactured by Wilhelm Layher GmbH & Co. KG and this report has been made for their Swedish division Layher AB. The Kedertruss, designed in Germany according to German designcode, has been recalculated concerning Swedish conditions according to Eurocodes and a ongoing European standardization project. The two-dimensional program Winstatik Frame Analysis has been used for evaluation of load effects. Capacity has been calculated by hand-calculations and it has been verified that the Kedertruss in its larger spans isn?t able to withstand the loads.
GAP i efterfrågan : En undersökning om efterfrågan på miljövänliga transporter
Purpose: Corporations today see a greater responsibility towards society regarding the environmental impact of their actions, using available transportation options that are more eco-friendly can reduce this impact significantly. Martinsen and Björklund (2012) identifies a set of gaps between supply and demand of green logistics services. This paper aims to address what it is that affects the demand for these alternative solutions and what could be done to increase the usage of them, thereby decreasing this gap.Design/methodology/approach: A quantitative study with six Logistics Service Providers (LSP) and 24 companies that purchase transportation services, all operating in Sweden. Data is collected through semi-structured telephone interviews with people responsible for the purchasing of transports as well as key account managers within the service providing companies.Findings: Just as the LSP?s interviewed in this paper thought, the main focus of the transport buying companies are the costs.
Att ta cykeln till arbetet : en studie av Stockholms satsning på cykelpendlare i jämförelse med Köpenhamn och London

This is a study of the use of bicycle as an option for commuting to work. It is a comparison between three cities: Stockholm, Copenhagen and London. The comparison is focused on solutions that benefit commuter cyclist and performed by studying cycle policies and other related documents.
Ledtidsreducering ur ett värdeflödes-perspektiv
This case study is performed within the production of Sherwin-Williams, Bellö. The purpose is to increase the understanding how a value stream can function more efficient, from a lead time perspective. With the analytical model that is build up on known theories, the purpose have been fulfilled. Mapping of value and non value time for four products thru their respectively process reveals wastes, which is, waiting, transport and movement, incorrect processing and set-up time that in it self create transport and movement. Thru identified wastes that causes loss in lead time suggestions of improvement has been proposed.
CSR inom livsmedelsbranschen : Studie över ICA:s CSR-arbete inom transport av varor
Corporate Social Responsibility, ett företags samhällsansvar, har på senare år fått större plats i näringslivet. CSR bygger på idén att företag frivilligt redovisar vilket socialt, etiskt, miljömässigt och ekonomiskt ansvar de tar inför sina intressenter. En företagsbransch med daglig inverkan på världens samhälle är livsmedelsbranschen. Branschen har ett välutvecklat och komplext logistiksystem där transportverksamheten är en central funktion. Syftet med denna studie är att beskriva och utvärdera dagens CSR-arbete ur ett miljöperspektiv inom livsmedelsbranschens transportverksamhet.
Flödesoptimering i begränsande resurs
Most companies have a bottleneck in their production, that is a constraining re-source. When the demand is higher than the capacity in the constraining resource it is impossible to produce the demanded output. This problem leads to delayed deliveries, unhappy customers and ultimately to decreased revenue. Bottlenecks therefore has a significant role in production and must be handled thereof.MW Power in Sävsjö, Sweden designs and manufactures water and steam boilers for the customer's unique needs. MW Power invested in a new plasma cutting ma-chine but the machine has not reached the expected capacity.
Transportkvalitetshöjande åtgärder : en fallstudie vid GP-Last
This thesis has been done on a haulage contractor company named GP-Last (AB Gustav Perssons Åkeri) and the purpose with the paper was to analyse their traffic from Malmö to Stockholm and leave suggestions on efforts that GP-Last can use to increase their level of transportation quality. This has been done with two main questions, which problem do they have today and which efforts they need to do to solve their problems? Through a case study with interviews as method to collect data it showed that GP-Last had four main problems. Not enough information about their freights. The transport planning unit in Malmö doesn?t have the exact delivery address when GP-Last begins to bring in the gods. There are no clear routes.
Avskiljning av ammoniumkväve och fosfatfosfor i reaktiva filtermaterial : skak- och kolonnförsök
In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. Five different kinds of filter materials with reactive surfaces have been studied concerning their capacity to absorb ammonium and phosphorus from wastewater. The materials that were examined are Filtra N, wollastonite Filtra P, blast furnace slag and Polonite®.

BIM på Trafikverket : Förslag till en utvidgad investeringsprocess
2013 a decision was made that all projects at the Swedish Transport Administration shoulduse BIM (Building Information Modeling) to some extent from 2015. BIM is an approachthat allows for streamlining of projects by the use of a 3D-model created in an early stage ofthe project. The 3D-model can carry information about the facility throughout its life cyclefrom planning to management. The use of a 3D-model can help the project to detect errors inearly stages of the project when it is easy and cheap to fix the error instead of finding theerror in the construction phase when it is costly and time consuming to fix it. 3D-models alsolead to improved communication both within the project groups and with the public.

Uppföljning och analys av Stockholms stads solcellsanläggningar
During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..
Kan man minska bilåkandet i staden? : sett ur ett stadsplanerarperspektiv
The reason why this essay is written can be parted in two, whereas one would be the global trend of urbanization that occurs to this moment and forward, whereas the other would be the debate of how motorism has come to be an issue of sustainable management of our cities and our environment. In purpose to deliver a thorough understanding of how the car and its capacity has come to shape the society of today, and to emphasize the problems it´s brought, a historical survey has been made, followed by the report of problems to the society formed by the needs of the car, discussed in several environmental issues, such as jamming, noise and air pollution. This is followed by the discussion of potential solutions for how city planning could return to the focus of the human scale and perspective, in purpose to correspond with the issue of ways to decrease the car use in towns. In conclusion, the given solutions are discussed, where examples like shared space, investment in public transport, mobility management and the theory of the assembled city are included, with aid from literature, to finally conclude the essay with personal thoughts of how the planning of today, or the given solutions, really are the result of sustainability for city planning from a human perspective.
Energieffektivisering av linjesjöfarten till och från Tasmanien
Tasmania is a state in Australia, and is also the country?s largest island. It is separated from the main land by a 429 kilometer wide strait. Every year, a large amount of people, cars and goods are transported to the island using a government owned ferry line, which generates approximately 300 million Australian dollars to the state?s economy ,every year. This bachelor thesis investigates the possibility of reducing the fuel consumption for the ferry traffic to and from Tasmania, which would also reduce the overall cost.
