Trafikverket : Kritiska faktorer i projekt inom avdelningen Nationella Projekt
This study has been made on behalf of the Swedish Transport Administration to study the work of the department National Projects. The Swedish construction industry has for many years been characterized by low productivity. By being the largest purchaser of contracts in the industry the Swedish Transport Administration has a unique opportunity to influence the productivity. In order to improve in productivity The Swedish Transport Administration is adopting a new role in which they will order more turnkey projects. In our study, we will focus on how one department within the Swedish Transport Administration, National Projects, can perform successful turnkey projects.To clarify how the department National Projects can perform successful projects, this study identifies critical factors for projects and their links to different phases of the project.

Purpose: ? To develop a method for analysis of the future course of issues regarding technology and society in interaction.? To apply and test the developed method through a case study, where it is used to analyze the future of the Russian fuel market.
Schemaläggning av hissar vid prioritetsanrop : En studie i hantering av prioritetsanrop av hissar på svenska sjukhus vilka styrs av Nearest Car Algorithm
In our modern society, time is important. Technology is used in countless ways to faster get us from one point to another. The purpose of this report is to inquire whether there is a way to implement an option for personnel at Swedish hospitals to claim priority on an elevator call, and to do this in an efficient way. An ordinary elevator system has been simulated with an implementation of textit{Nearest Car algorithm}, an algorithm which calculates the most suitable elevator car to serve a specific call considering the distance between the call floor and the car and the direction. Along with this algorithm, different ways to handle priority calls has been implemented to see how they affect the mean transport time for both passengers with priority and regular passengers in the elevator.

Fast Service in Fast Fashion-En kvantitativ studie av kundrespons till självserviceteknik i fast fashion
The success of self-service technology in retail grocery stores cannot be ignored, and the fact is that every other grocery store in Sweden has implemented the self-scanning or self-checkout systems. The trend is that the technique is spreading into other markets with potential to increase productivity for companies and enhance the service for customers. Fast fashion is one branch that is left untouched by the development in payment processes, and despite the leading companies extensive focus on fast service, the concept of self-service technology has not yet been tested. This paper undertake a quantitative, experimental approach to the issue and examines the effect self-checkout would have on Fast fashion- customers. By presenting a scenario with and without self- checkout and afterwards asked about the respondents experience, we can provide the marketing world with new insights.

Uppbygnad av ett logiskt flöde vid produktionsövertag
The situation at Plastal AB is following; the plant in Simrishamn has not capacity enough but the plant in Kristinehamn has unused capacity. My task with this master thesis is to build a logistic flow between this two plants, optimize purchase quantities and ensure delivery safety.The production of the Intermediate Section (LS) will be divided between the plants. The LS will be produced in the following way; the injection moulding process will be done in Simrishamn and the assembling and lacquering processes in Kristinehamn, The reason to divide the production is to ensure delivery safety. Plastal AB can not move the whole production of the l.S because the two plants have different processes (moulding res. injection moulding).When the 1.5 has been transported to Kristinehamn following moments are included in this order; lacquering, welding and assembling.
Förslag till modell av kemikaliespridning i mark anpassad för användning vid räddningsinsats - Kemspill Mark 4.0
After emergencies involving chemical spills it is of great importance that correct measures are taken with short notice, both for the security of people and in order to minimize future environmental consequences. The RIB-unit at the Swedish Rescue Services Agency initiated this study, the aim of which is to propose changes to the existing chemical transport calculation tool: Chemical Spill 3.4, included in RIB - Integrated Decision Support for Civil Protection, so that it can be used for decision support as well as in preventive work. A rough estimation of chemical transport in the subsurface is considered being of great importance when making decisions during emergency response operations.The proposition presented in this report is a non site specific chemical transport model which is designed to give a rough estimation of NAPL flow in homogenous isotropic soil shortly after an instantaneous release. The model can be used at two levels; both in situations without access to information on subsurface properties, and with more accuracy in situations with knowledge of the included parameters. For that reason the user can choose among predefined alternatives or assign the parameters a numeric value to increase the quality of the model output.
Kylcontainerns teknologiska utveckling : Innovation och utveckling av containerteknologin fo?r transport av kylda varor
This report is part of a Bachelor?s degree corresponding to 15 creditsat the Royal Institute of Technology, Stockholm. The work hasbeen carried out by Max Wikander, author of the report, supervisedby Lanie Gutierrez-Farewik and Erik Dijkstra.Gait analysis includes measurement, characterization and assessmentof human movement and is used to assess kinematic or otherabnormalities during gait. Center of rotation and the axis of rotationof a joint are fundamental parameters in motion analysis. However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.
Produktivitet och kostnader vid skörd och transport av skogsbränsle från klena gallringar
Syftet med denna studie var att undersöka ett maskinsystem för uttag av trädbränsle i klena gallringar i norra Västmanland och södra Dalarna för Mellanskog. Genom driftuppföljningsdata kunde produktiviteten och kostnaderna för maskinsystemet beräknas, samt kostnaderna för sönderdelning och transport och hur dessa förändras med transportavståndet till industri.
Resultatet visar att skördarens produktivitet är beroende av storleken på skördad medelstam, samt att skotarens produktivitet sänks med ett ökat skotningsavstånd. Den totala kostnaden för drivningsarbetet för ett medelobjekt (sett till maskinsystemets produktivitet) i denna studie var 178 kr/m3f inklusive kostnader för flytt, planering och tillägg för vinst. Om man bortser från dessa kostnader uppgår kostnaden för skördaren till ca 88kr/m3f och kostnaderna för skotaren till ca 61kr/m3f. Att enbart sönderdela materialet kostar 58 kr/m3s och kostnaden för transport beror på tranportavståndet, ett längre avstånd innebär en högre kostnad.
Att våga vara innovativ: En fallstudie om affärsutveckling av befintliga produkter i ett högteknologisk företag
High technology companies in Sweden spend a huge amount of money on research and product development in proportion to what they get back in earnings from their inventions. Product development has traditionally been regarded as much more important than business development. This thesis aims to point out the critical factors behind successful business development processes for high technology companies. We have chosen to make a case study of Hexagon, a highly successful and innovative company within the measurement technology business. Internal and external actors that are important for business development have been identified and interviewed in order to understand how ideas are developed and executed.
Trafikinformation via SMS
Abstract
The technology has made it possible for you as a train traveller to be
available in other
places than stations and on the train. You now have the possibility to
communicate by
the phone or through the Internet to get information about the train you want
to take.
Development in mobile technology gives us new possibilities to communication. We
want to find out whatever SMS would be a suitable approach to inform passengers
about delays. The problem formulation is
?If the technology is available to inform the passengers about delays in an more
effective way than today, then why not use it?
The ?Kustpilen? that operates in Blekinge and Skåne is the case for our study.
Varför miljöredovisning? : en undersökning av lastbilstransportbolag
Today?s political debate on environmental issues and environmental thinking, alongside the Swedish presidency of the EU and Climate Conferences shows that the environment is an important topic. Environment is important, not only in politics, but also for companies and the demand of environmental strategies and environmental reports has increased. This leads to an increased pressure on firms to begin to report on environmental concerns and to create active systems for environmental thinking.The aim of the present study is to examine why firms in the transport sector, mainly lorry transports, reports environmental aspects and what drives these companies to create these reports.Based on stakeholder and institutional theory we aim to examine to which extent stakeholders affects the environmental accounting and reporting. We also aim to explain how the organization is influenced to incorporate external and societal environmental procedures.
