Cash-to-cash-styrning : ett spelteoretiskt angreppssätt

Objective: The objective is to examine if long terms of payment are created because of a perceived zero-sum game in the cash-to-cash cycles between companies. The study will also examine if dependence effects the dependent companies Cash-to-Cash-cycle because of long terms of payment. Scientific method: The study uses a qualitative and a quantitative method, where primary data is collected from semi-structured interviews. Additional primary data is collected from an unstructured interview with an expert in the field of which is examined. Additional data has been collected from the studied companies? annual reports.Theoretical references: The primary theory has been Game theory, where the researchers have used this theory to analyze the behaviors of the companies.

Fördelning av en kostnad utifrån olika rättviseteorier :

The increasing road traffic in Sweden will require investments in the infrastructure that the tax withdrawal of today will not allow according to a new government report, SOU 2006:33. An existing willingness to pay for those investments has therefore become an alternative to increases in taxation to be able to cover the costs. A proposal to let the willingness to pay, alternatively increases in taxation that act proportional, decide how a cost is distributed can be said to be related, but not fully correspond, with different theories of justice described by Robert Nozick and John Rawls. It can therefore be interesting to see how the two different theories of justice are edified and how they distribute a joint cost. The aim of the first part of the thesis is to present and criticize Rawls' and Nozick's theories of justice in a common formulated economic model.

Risken för översvämningar vid de svenska kärnkraftverken : en statistisk och historisk extremvärdesanalys

This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .

Värdeflödesanalys på Saab Training Systems i Huskvarna

Saab Training Systems (STS) in Huskvarna is manufacturing material for educationalpurposes to armies worldwide. They are now implementing parts of the Lean productionconcept in their organisation.One part of the work with Lean production is to eliminate waste. To be able to identify waste,value stream mapping is a good tool and also what we used in our thesis. To gain a betterefficiency in the production of Personnel Detector Device (PDD) flow was one of our goals.The PDD is a harness used during battle training which registers if the user is being hit by itsenemy.Our work with the thesis started up with a short education in Lean production and in valuestream mapping (VSM). The work proceeded with a VSM of the production flow of the PDD,interviews were made and studies of literature were done to gain greater knowledge of thesubject and solve the task.The VSM resulted in five areas which were followed up out of those six we identified.

Effektiv Planering enligt Lean Production : En fallstudie på Sandvik Mining and Construction

Due to a constantly increasing competitive pressure it is of great importance to constantly strive for improvements in order to gain competitive advantages. Lean Production is a concept that has been introduced with the aim to minimize waste and increase profitability. The purpose of this report is therefore to investigate how to perform effective planning according to the principles of Lean Production, in companys with customer exclusive products, through a case study at Sandvik Mining and Construction (SMC), and to investigate how SMC kan improve their planning of drifting rods at the production unit in Sandviken.The study started by creating a theoretical framework, to describe the subject planning and planning based on Lean Production. This frame work constituted the base for the case study which took place at Sandvik Mining and Construction, and also for the model and planning tool that has been introduced.The result of the study is partly a general model with factors that contribute to a more effective planning. These factors has beed identifed as SMED, which focuses on reducing set up times and in the end to facilitate the planning.

Lagerhantering och materialflöde vid SSAB Tunnplåt AB i Finspång

Detta examensarbete är skrivet på uppdrag av SSAB Tunnplåt AB i Finspång. Syftet är att, för en framtida produktionskapacitetsökning, utreda konsekvenser på materialflöde och lagerbehov i lagren för förvaring av råmaterial, färg och färdigt material. Examensarbetet skall också ge förslag på åtgärder för att, ur lagringssynpunkt, klara av kapacitetsökningen. Produktionstakten är idag 110 000 ton plåt per år och ökningen kommer att ske linjärt, med ett delmål vid 150 000 ton per år och en slutlig toppkapacitet på 170 000 ton per år. Inventeringen av råmaterialförrådet visar att materialet har en genomsnittlig liggtid på sex dagar och att lagernivån varierar mycket över veckan.

Framtagning av nyckeltal som indikerar kvalitetsbristkostnader : Development of key performance indicators revealing the cost of poor quality

Since the 1980s, companies have taken a larger interest in quality and it´s economic impact within the company. Having the knowledge that it´s not quality that costs money, but it´s rather the lack of quality. The work immerses itself in the field of cost of poor quality and the development of key performance indicators.The thesis is performed at Bufab Holding in Värnamo. Bufab Holding is a trading company which mainly buys and sells C-parts. C-parts include fasteners, other small metal-, rubber- or plastic parts such as wires, springs and electronic fasteners.The aim of this thesis was to make a survey of the cost of poor quality and to find key performance indicators (KPI) for cost of poor quality that can be continuously monitored.

Undersökning av fosfatsbegränsningseffekter på Escherichia coli AF1000 för bättre förståelse av 3-hydroxybutyratproduktion

High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.

Ekonomisk analys ? kostnadseffektiv anpassning av skogsbruket med hänsyn till rennäringen : en fallstudie om Norsjö Distrikt, Holmen Skog

Förutsättningarna för skogsbruk och rennäring skiljer sig mycket från varandra, likaså markanvändningen och synen på hur skogsmarken bäst skall användas. Detta har lett till återkommande konflikter mellan skogsbruket och rennäringen. För att rennäringen skall kunna bedriva en uthållig renskötsel behövs tillgång till sammanhängande områden med gammal och relativt obrukad skog. Skogsbruket i sin tur måste regelbundet avverka skogen för att erhålla en hög ekonomisk lönsamhet. Inom en stor del av Holmens skogsinnehav bedrivs skogsbruk och renskötsel på samma marker.
