Samspelseffekter vid kapacitetsförbättringar. : Exempel från Dalabanan.
The trend in the transport sector is moving towards eco-friendly, fast and convenient transportation,this results in higher demands on railway transports. To meet the demand and quality requirements,the Swedish railway network will have to expand. The cheapest way is to expand little by little butwhat impact do these small steps actually have on the capacity?This thesis examines the interactions of different improvement for the capacity on a single-trackrailway. Through simulations in the software tool RailSys this report studies what effect block signals,extra meeting stations and rebuilding existing two track passing loops to three track loops have onthe capacity.
En branschanalys av den svenska mobilmarknaden -Strategi, konkurrenssituationen och 4G:s påverkan
Background and problemThe Swedish mobile market is highly competitive despite the oligopoly that currently exists. A short product life cycle together with fads and new innovations puts pressure on the operators to respond to the ever changing environment and to develop and adapt their strategies after it.As a previous study regarding a specific operator?s strategy was cancelled due to the extensive confidentiality surrounding it, an interest was sparked to perform an industry analysis as this is clearly something the actors spend a great deal of time on developing. The launch of the 4G network will offer new opportunities for the operators regarding products services. It may also impact the competition on the overall market.PurposeThe purpose of this thesis is to present a deep analysis of the industry and give the reader a comprehensive picture of existing conditions.
Vattenvård vid slutavverkning : före och efter vattenvårdsutbildning på Stora Enso Skog, distrikt Siljan
In 2006, Stora Enso Skog implemented an education program in water management for
harvester operators, timber purchasers, cut block planners and supervisors. The focus of the
program was creating stream crossings with minimal harm to the stream and the surrounding
riparian area. This main purpose of this study was to determine the difference in work
procedures before and after participating in the program. The methodology consisted of field
studies and interviews with harvester operators and their supervisors.
The field study looked at how the streams had been crossed concerning the number of
crossings, visible damage to the stream and/or the riparian area made by the machines.
Biological parameters such as the width and dept of the stream and amount of large woody
debris in the stream were also measured.
The field result from 30 harvesting sites showed no significant difference between sites that
had been harvested before or after the education program. But the harvester operators and
their supervisors experienced an increased concern for watersheds after the educational
program.
Prim, Stadsförnyelse i Barcelona
This final project discusses renewal and upgrading of the area of Prim. It is discussed how this industrial area can be an attractive neighborhood with a varied range of services and commercial trade. Prim is located 2km north-east of the center of Barcelona. The area boarders to a deep railway valley that historically has separated Prim from its neighboring districts. At present there is almost no housing, services or commercial trade within the area and the industry is discontinued or the existing industrial buildings are derelict.
Produktionsavbrott - förekommer det effekter att lära av?
A large part of the time losses in production in modern manufacturing industry are a cause of unplanned interruptions in production. In this essay we have studied the effects of an unplanned interruption in production. The study was performed during one month on a press production line at Volvo Cars Body Components (VCBC) in Olofström. The effects of the interruptions have been studied on the basis of two perspectives of the environment of the production. The study started at the level of automation and was mainly done as a survey of the unplanned interruptions in production.
Utvärdering av traktplanering på SCA Skog
This study is an analysis of a survey that harvester operators working for SCA Ångermanland Skogsförvaltning have been participating in. The purpose of this study is to try to show the harvester operators opinion about the forestry planning that SCA provides. Hopefully will this information lead to suggestion about what part of the forestry planning needs to be improved, if any is needed? Unfortunately only 30 / 60 questionnaire has been returned so no conclusion can be made, except about those who have answered the survey.
The answers of the survey indicate a number of areas that needs to be improved. The marked routes needs to be more visible and the education about timber landings must be enhanced.
Grundvattenpåverkan kring järnvägstunnlar i berg
Rock groundwater has always caused major problems when tunnelling. Water leaking into tunnels can cause large problems, not only on the construction itself but also on the environment. A continuous water leakage can lead to a declining water supply, and geotechnical problems can occur as subsidence in the ground. Therefore it is of great importance to predict the consequences that can appear in the surroundings due to a declining groundwater surface.The aim of the study was to investigate different methods for predicting leakage and changes in groundwater level due to tunnelling excavations in rock. This thesis was performed by comparing mathematical methods, actual groundwater changes and results from preliminary investigations.Investigations were made for three railway tunnels planned by Botniabanan AB.
Utredning och implementering av en prototyp för integration av Prevas FOCS och ABB 800xA
ABB and Prevas have initiated a collaboration to sell a system to optimize steel industry furnaces, called FOCS. The purpose of this thesis is to investigate possibilities for integrating Prevas FOCS and ABB 800xA.The result of the investigation is used for an implementation of a prototype of the integrated system. The study shows a general method that can be used when implementing two software systems. The prototype of the integrated systems is made with usability principles in mind. This is a very important aspect in order to create a good working environment for the operators of a steel plant.
Från plats till resmål : Etableringsprocessen
In this thesis we have examined why the establishment process of travel destination is essential for the tour operators and how the process can be influenced by different conditions. The thesis is written from the perspective of the tour operators and with the tour operator Ving as our case study, we have been able to create a picture of how the establishment process of travel destination may look like.We have chosen to deal with some different areas in this thesis that all are important for the creation of a holistic picture of the process. The overall segments listed in this thesis are the process itself, the tourist, marketing, the product creation and demand. By connecting our theoretical framework to the collected empirical data from our case study, we have analyzed the establishment process and drawn our conclusions..
Karlshamn-Wislanda Jernväg : Maktelit och nätverk i Karlshamns stad vid banans tillblivelse 1855-1874
The aim of this essay was to describe the power elite of the Swedish town Karlshamn, and its influences on the local political process before the realization of the narrow-gauge railway Karlshamn-Wislanda-Jernväg. During the mid 19th century, a revolutionary period began in the Swedish pre-industrial epoch. The political and institutional regulatory frameworks were disassembled and restructured, away from protectionism and centrally controlled administration, for the benefit of free trade, local self-government and liberalism. The changes were carried through during times marked by a drastic increasing native population and upcoming demands for adjustments to meet the growth of the industrial-, trade- and labour markets. An essential industrial development factor was the building of the national railway network, which started after some important decisions in the Swedish Riksdag during the 1850´s.
Underlag för implementering av 5S
ABB Capacitors Ludvika started their LEAN-project in november 2010, but still has not the whole factory been introduced to the LEAN-tool called 5S. 5S is only implemented on the ?easiest? work-areas.By implementing 5S, at the workingstation called inburkningen, would make the workstation and the area around it much more structured, clean and systematized. The operators are a little bit skeptical to the work that includes continuous improvement today, because they can not see any progresses. If 5S were implememted the operators would be able to avoid searching for tools because with 5S, each tool will have a specified place at the workstation.5S would simplify the cooperation between the shifts, because 5S includes clear instructions for how the workstations will be cleaned after each shift.This report will include my recommendations, thoughts and opinions regarding however ABB Capacitors Ludvika should implement or not implement the LEAN-tool 5S.
Markering och risning av basvägar inom slutavverkningstrakter : en intervjustudie hos maskinförare och planerare
In an attempt to prevent ground damage and to reduce harvesting costs, StoraEnso's districts Värmbodal and Fryken, selected a number of final felling areas where the base roads have been marked by planners in the districts. The parties involved in the experiment are mainly planners, harvester operators and forwarder operators. The purpose of this paper is to determine the findings of this trial and to find cost savings or lost revenue. This has been done with a sample of interviews from the involved parties who logged the chosen felling areas. Literature about the interview process has been used to facilitate data collection, interpretation and analysis of the material.
If we look at profitability based on assumed income and expenditure, revenue per MWh would be 63 SEK.

Organisering av komplexa organisationer - En studie av den svenska spårunderhållsorganisationen
To achieve a working collaboration in a big, complex organization where there are vast requirements on both quality and profitability is not always an easy task. An example of this is the organization that was created in the Swedish railway industry following a series of deregulations during the past 25 years. A partial market in this organization is the railway maintenance. In order to achieve a working collaboration between actors in this organization the so-called Purchaser-provider model (PPM) is presently used for the procurement of rail maintenance projects. Previous research has shown that this market-based instrument has clear positive effects regarding the cost-efficiency but hinders the collaboration.
Marknadsföra Innovationer: Hur länken mellan teknologisk innovation och värdeskapande är avgörande för framgång
Near Field Communication, NFC, is a short-range wireless communication technology that enables data exchange between devices in a secure way. A NFC phone has the potential to enable the convergence of wallet, phone and keys, but as many other technological innovations, the launch is struggling. We have discovered that technological innovation is only the first step. For an innovation to be adapted, there need to be business model innovation too. Many actors form the ecosystem of NFC and the business model for each service is still an unsolved problem.
