Cycle time has a direct influence on number of returnable crates needed and therefore a crucial parameter for cost structure and pricing of the user fec in the pool system.For providing the growing market, number of crates has to increase as well as the utilization of existing crates. To accomplish this aim, cycle time for the whole supply chain has to be fully unravelled and understand.The purpose is to map cycle time and stock movements, to see how, where and when crates are being used in the supply chain. The goal is to make a method of cycle time calculation, together with suggestions of improving the pool system and decrease cycle time.The study has been a combination of qualitative and quantitative research and comprises the three biggest wholesalers in Sweden; ICA, Coop and Axfood. Furthermore have 65 grocery shops, connected to the wholesalers, been investigated and mapped.The study has come to a conclusion that cycle time for an average returnable crate is 19 days. The full-size and half-size crates have a bit longer cycle time, 21-22 days, while Dual Height-crates and shallow haif-size crates have 17-18 days.

Syfte: Syftet med denna uppsats är att studera om förändringar i arbetet med rörelsekapital hade ett samband med lönsamheten i företag. Som mått på rörelsekapital används Cash Conversion Cycle och som mått på lönsamhet används ROA.Teoretiskt perspektiv: Den teoretiska referensramen består av teorier om Working Capital Management, Cash Conversion Cycle, Lean, Supply Chain Management och Supply Chain Finance.Metod: I denna uppsats används en kvantitativ metod där sekundärdata samlas in från årsredovisningar för 2005 och 2013. Denna data ligger till grund för fyra korrelationsanalyser. Den beroende variabeln i korrelationsanalyserna är ROA och defyra oberoende variablerna är Cash Conversion Cycle, dagar i lager, dagar som kundfordring och dagar som leverantörsskuld. Urvalet i denna studie består av svenska aktiebolag inom branschen tillverkning och industri med fler än 50 anställda.Empiri: Empirin består av fyra tabeller som presenterar de beräkningar som gjorts.Slutsats: Sambandet mellan förändring i Cash Conversion Cycle och förändring i ROA blev väldigt svagt positivt men inte signifikant.

The bicycle is an individual means of transport. Many people prefer to cycle over short distances and in congested areas rather than take travel by car or public transport. 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.

Tumour development occurs to a large extent because of dysregulation of the cell cycle. Of particular importance are defects occurring in the G1 phase. The reason why G1 is critical is because of the influence of several signals (external signals as well as cyclins and cdks) on this stage. The G1 phase can be divided into two parts, G1pm and G1ps. Each part has its ?own? restriction point which needs to be passed in order to progress to S phase.

It generally takes 10 to 12 years for a new drug to hit the market. The pharmaceutical industry invests huge sums in these early stages of research and development. In spite of the rapidly rising research and development expenditures fewer and fewer blockbuster drugs are being developed. Longer lead times and aggressive generic post-patent competition have narrowed the timeframe for the pharmaceutical companies to profit on their investments.In the face of these threats the pharmaceutical industry has developed a battery of strategies to prolong market exclusivity and to maximize return on investment. These emerging strategies are commonly known as Life cycle management (LCM), which actually is more of a concept than a method.

Slöseri är ett stort problem på byggarbetsplatser. Ett koncept där minimering av slöseri ärcentralt är Lean-manufacturing. Detta arbetes syfte var att utreda hur förbättringsarbeteanvänds på byggarbetsplatser.

Detvisade sig att de inte har något system för förbättringsarbete.

Life Cycle Cost, often abbreviated as LCC, is a common tool for comparing the total cost of different alternatives, such as heating and cooling methods. Common heating and cooling methods in Sweden are geothermal energy, district heating and district cooling. This report aims to evaluate how different heating and cooling methods differ from each other while being applied on three different types of buildings, using selected LCC-models. Information about the selected LCC-models wasretrieved from each separate model and its website. Reports and agencies were used as sources for information about the heating and cooling methods.

AbstractThe work will give the picture of what four- and five-year-olds know about the water cycle in nature and in the society. Is there any difference depending on whether a boy or a girl is answering? The work will as well try to describe a picture of how a pre-school could plan their work on a sustainable society, science, and increased gender equality. To answer these questions the information has been received from interviews with children and by studying pre-school?s local plan.    Earlier research on the area of water shows that it is important before working with a new topic to find out what knowledge the children already have, so that the process could be as worthwhile as possible.

En hållbar tillväxt, hög konkurrenskraft och goda möjligheter att anställa nytt folk kan nås om företag blir bättre på att utveckla sig själva och bygga samordnade produktionssystem, vilket har blivit av allt större vikt.Fallstudien är utförd på företaget LKM AB, som producerar olika kablar och kablagemonteringar. Huvudsyftet med fallstudien är att utreda hur kundanpassningen påverkar den interna effektiviseringen av ett produktionsflöde i en tillverkande verksamhet.En nulägesanalys utfördes för att etablera nuläget och analysera den, fokus låg därefter på packningsoperationen, vilket är operationen närmast kundönskemålen. Författarna påbörjade därefter att arbeta med Kata genom att sätta upp ett måltillstånd, detta visar vart företaget är idag och vart de vill vara inom cirka en månads tid. Genom att arbeta med ett effektivt experimenteringsverktyg kallat PDCA-uppföljningsblankett, måltillståndet var uppnått inom tidsperioden och resultatet blev följande:- Leveransen gick på en pall istället för fyra stycken.- Packningstiden reducerades med 60 %.- Kontrolltiden hos kunden reducerades med 30-40 %.Detta visar att metoden och arbetssättet är mycket effektivt..

The aim of my thesis was to do a Life Cycle Assessment (LCA) of an average thread tap that is manufactured by Dormer Tools AB, and to create a practical model that the company can use in order to study other thread taps from an environmental perspective.The method of LCA is used to investigate the environmental effects of a product during its life cycle. This is a gate-to-grave analysis with focus on steel and thread tap manufacturing, coating procedure, use, waste management and transports. Three common coating types were compared separately. Steel manufacturing answers for the highest energy and raw material consumption under the life cycle of the thread tap. Its emissions contribute to global warming, acidification and eutrophication above others.

I denna rapport har det utförts två fallstudier från två olika vindkraftsanläggningar och med hjälp av en utarbetad modell har livscykelkostnaderna jämförts för de två fallstudierna.Resultatet visade att livscykelkostnaden per producerad kWh sjunker allteftersom den installerade effekten blir högre.Kostnadsmodellen som utarbetats och tillämpats för resultaten har visat sig ha hög verifierbarhet då resultaten har varit jämförbara med litterära studier..

Digital preservation is a relatively new subject to Swedish archives. Alhough computers have been used for a long time, preservation has been made on paper and stored on shelves. These days a lot of cities in Sweden have investigated how to best secure the digital information for the future through electronic archiving, e-archives. One option is to hand in the information as soon as possible, but to let the producer keep the information ownership yet some time. The idea is to let the producers of the information answer questions and hand out material, since they are more competent on their field.

Environmental issues are global problems and they are a major challenge for any successful organizational business worldwide. Many challenges and opportunities emerge during the certification process of an EMS. Therefore it is interesting to contribute in understanding these emerging problems during this process.The aim of this study is to explore how the environmental objectives could be achieved at preschools in Uppsala, investigate the perceived challenges and opportunities and to identify the outcome of implementing the ISO 14001, Green Flag at such set up.A qualitative method is used and three Green Flag certified preschools, affiliated to the Uppsala Municipality and located at different geographical location were selected. A structured interview with the environmental representatives from the preschools and the municipality was completed. The so-called PDCA-cycle as a method of evaluating sustainable development and analysing the imperial data is used.The study showed that environmental certification constitutes a great challenge for the municipality of Uppsala.

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.
