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.
Utveckling av en HBV/PULS-model med sammanfogade markfuktighets- och responsrutiner
Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.
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.
Berättelse och mekaniker i konflikt : Ludonarrativ dissonans effekt på narrativ transport
För att kunna skapa intressanta och engagerande berättelser i spel behövs förståelse för hur spels unika egenskaper påverkar berättande. Ett spelnarrativa kan delas upp i det inbäddade narrativet, som består av till exempel texter och dialog, samt det emergenta narrativet, som uppstår ur spelets gameplay. När dessa två delar inte stämmer överens uppstår ludonarrativ dissonans. I detta arbete undersöks hur ludonarrativ dissonans påverkar narrativ transport, det vill säga inlevelse i en berättelse. Två versioner av ett berättelsedrivet spel skapades med olika mekanikerna för att uppnå låg respektive hög ludonarrativ dissonans.
Impact of EU-regulation on pigs? welfare during transport
Each year 225 million pigs are transported within the European Union (EU) for slaughter, fattening and breeding. This results in poor animal welfare due to the fact that animals are exposed to several numbers of stress factors in the vehicle during loading, transit and unloading. Animal welfare can be defined as how well the animal attempts to cope with its environment and during transport there is often severe difficulty for the pigs to cope properly. There is a growing societal concern for animal welfare. This resulted in that the European Union enacted a law called the EU-regulation with certain directives of how to improve the welfare of the animals during transport.
H?LLBARA INTERMODALA TRANSPORTER I EU En studie om EU:s transportpolitiks inflytande p? samverkan mellan transportslag f?r h?llbar mobilitet
The transport sector is one of the biggest pollutants in the European Union. In relation to
transport policies and environmental policies, intermodal transportation solutions are of high
relevance to establish a sustainable transport sector for the future. Intermodality which is
defined as smooth transition between transport modes is a key figure for how modal shares
are divided between the modes of transportation. The aim of this bachelor?s thesis is to
examine the research gap whether policies intended for a specific transport mode affects each
other in relation to EU policies intended for intermodality.
Migration och vegetationsupptag av radiocesium i åkermark - en långtidsserie av mätdata samt en långsiktig simuleringsmodell :
Abstract
The accident in 1986 at the nuclear power station in Chernobyl, Ukraine, dispersed radioactive cesium over large areas of Europe. The half life of 137Cs is 30 years and this radionuclide also behaves like potassium, which means that it can easily be taken up by the vegetation or be adsorbed in to the structure of clays, principally illitic clays. When radiocesium decays ionizing radiation is emitted, which is harmful to humans that are exposed, either directly or indirectly through food intake. It is there-fore important to know what happens to the cesium that is dispersed into the environ-ment.
In this project a simulation model was constructed to simulate the adsorption and transport of radiocesium in the soil and plant uptake.
Politiskt organisationsbyggande - Vilken betydelse har samrådsprocessen haft i arbetet med att bygga upp en ny organisation för kollektivtrafiken i Värmland? : En fallstudie av arbetet med trafikförsörjningsprogrammet i Värmland
On the first of January 2012, a new public authority was formed in Värmland, due to a new legislation on public transport. The first task for the new public authority was to produce a plan for the development of public transport. In order to do so, it had to execute an extensive consultation process about the long-term goals of public transport. The purpose of the thesis is to investigate how a public authority can use a consultation process as a means to clarify accountability and produce unified goals. To answer that, I have done a case study about how the new regional public authority in Värmland for public transport has acted in the process of writing a plan for the development of public transport.
Crowdsourcing för en ökad medborgardialog. En studie om en ökad medborgardialog för Västra Götalandsregionens kollektivtrafiknämnd
Today, companies can take advantage of mass intelligence by making use out ofcrowdsourcing. Crowdsourcing is a business model that uses the power of the collective bythe offer of a problem by means of competitions in various social media. The benefit ofcrowdsourcing is that the company gets more creative and creative solutions to the sameproblem, which would not have been possible if the company solved the problem internally.The larger mass gains an insight into the company, which in return also releases power tothe company's development. The study aims to examine the way in which citizens can beattracted to participate in the development of public transport using crowdsourcing. The studyis based on both qualitative and quantitative approach since the study has a qualitative pilotstudy.
Skogsåkeriägares inställning till organisationsförändringar :
There are two groups of haulage contractors in roundwood transport , those who are contracted direct by the transport buyer and those who are connected to a freight company which in its turn is contracted by the transport buyer. Today the roundwood haulage is dominated by contractors with one to two lorries. The effort of coordinating transportation for a transport buyer is dependent on how many communication contacts that must be managed (how many individual haulage contractors the transport buyer has to work with). A structural change in the sector that leads to a decrease in the number of haulage contractors but an increase in the capacity of each contractor, makes it possible for a transport buyer to coordinate transports with fewer communication contacts. The reason why a company reaches a certain size can be explained by the number of contracts it makes and manages.
Transporter av prematura och sjuka barn
I Sverige sker cirka 2500 transporter av nyfödda barn varje år. Socialstyrelsen publicerade i slutet av år 2013 en ny vägledning ?Vård av extremt tidigt födda barn?. Ett av de områden som har prioriterats är neonatala transporter. Betydelsen av en väl fungerande transportorganisation är nödvändig för att skapa en säker och jämlik vård för denna patientgrupp.
Bil eller aktiv transport : Vad påverkar människor till deras val?
Syftet med denna uppsats var att undersöka vilka faktorer som påverkar hur förvärvsarbetande människor i Gävle använder sig av bil och aktiv transport när de transporterar sig till destinationer inom staden. Tio personer, fem butiksbiträden och fem lärare, intervjuades angående deras transportvanor och resonemang kring valet av transportsätt.Resultatet visade att aktiv transport var det vanligaste transportsättet till arbete, träning och butiker i centrum medan bilen var det vanligaste transportsättet till mataffären och destinationer på längre avstånd från hemmet. Avståndet till destinationen, tiden det tar att transportera sig, transport av eventuella varor, bekvämlighet, intresse av motion och rekreation, årstid, väder samt synen på ekonomi och miljö var faktorer som påverkade om deltagarna valde att transportera sig med bil eller aktiv transport. Definitionen på de olika faktorerna varierade mellan deltagarna, vilket kan tyda på att det är den personliga uppfattningen om de olika faktorerna som avgör vilket transportsätt som väljs. Det framkom ingen märkbar skillnad i resvanor mellan deltagare med olika utbildning och arbete..
Metod för användning av Geografiska Informations System vid långsiktig vägplanering : en studie genomförd på Sveaskogs marker i Norrbotten
The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas.
The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.

Interna processer : Modell för ett effektivt returstålsflöde
The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.
