Arbetssätt kring värdeflödesanalys för tillverkning av marina båtmotorer på Volvo Penta
Volvo Penta has been producing boat engines since 1907 and are world leading in this segment. They have today an extended range and also sell industrial power stations. Quality, safety and environmental care are three core values for Volvo and together they strive to give their customers the right product with the right quality.Volvo has developed a production system named Volvo Production System, VPS, and one of the pillars is continuous improvements. Within this pillar you can find value stream mapping, which is used to analyze the value stream through the process. This tool gives a wide perspective and helps to keep focus on the entire process instead of just parts of it.Volvo Penta in Vara has earlier done value stream mapping but without good results since they didn?t take set-up times and imbalances in account.
Svenskt Sigills kvalitetssäkring av spannmål :
Today there is a limited demand for quality certified cereal in Sweden. The demand can in the future increase and become a requirement for the entire market. Since the first of January 2005, grain producers in Sweden are food producers and traceability is important for the food industry. It is possible for grain producers to certify the productions under the certification IP SIGILL. The purpose of this essay is to explore why some grain producers continue to be certified while other producers end the IP SIGILL certification.
Flödesoptimering på sjukhuslaboratorium: En praktisk implementering av lean
This study has investigated the possibilities of implementing lean in a division of a hospital in Stockholm. The goal was to reduce the lead time for the patient to get his diagnose by implementing lean in the two production flows of this division. In order to accomplish it, a complete map over the value stream has been done. With the help of the value stream map and lean theory a list over the processes in contradiction with lean has been made. Finally propositions to implement lean and by this way reduce the lead times in this stream have been made out.
MILJÖCERTIFIERINGSSYSTEMET MILJÖBYGGNAD I PRODUKTIONEN : En fördjupning inom området ?Material?
The environmental assessment system Miljöbyggnad is a Swedish system initiated by Bygga-Bo-Dialogen to assess buildings with regards to three main areas; ?Energy?, ?Indoor climate? and ?Materials?. A building can obtain three different classifications depending on how well it manages to meet the demands. GOLD is the highest classification and is followed by SILVER and BRONZE. The majority of the measures needed to comply with the demands are done during the design phase.
Småhusproduktion : Utvecklingsmöjligheter hos JM AB
The Swedish building contractor JMRegion Öst would like to to investigatethe possibilities of developing andstreamlining the production of singlefamilyhouses. JM are producing singlefamilyhouses with prefabricated framesat a rate of about two houses per week.During construction, the different tasksare performed by JM?s own productionstaff but also by varioussubcontractors.When examining the schedules of recentlyproduced projects, it appears that allthe houses are more or less completedeight weeks before the customer moves into the house. During those eight weeksseveral operations are conducted such asinspections, installation of appliancesand cleaning procedures. The inspectionperiod constitutes between 25 and 35% ofthe complete construction period.By conducting interviews, it has beendiscovered that this final phase is anessential security buffer for delays anderrors that often occur.
Brunius, Zettervall och Graebe : ett jämförande studium av tre domkyrkorestaureringar
The purpose of this paper is to clarify and understand the difference between Brunius?, Zettervall's and Graebe's valueing of a historical building, the cathedral of Lund. Between 1833 and 1963 the cathedral of Lund went through three larger restorations. The character of the restorations however differs a lot between the three church architects, Brunius, Zettervall and Graebe. In a time of low interest for the Middle Ages and of many demolitions of churches in the countryside, Brunius stood out as a researcher and an enthusiast of that special time.
Traktstorlek före och efter omarrondering i Dalarnas län -frågor kring Lantmäteriets båtnadsberäkning
Land consolidation is a major problem in many countries in Europe. In Sweden, mainly the state of Dalarna, there is a strong consolidation of forestland, probably the strongest in all of Europe. The consolidation is a big obstacle for forest management and ownership questions due to the often long and narrow strips of land. One of the main reasons for land consolidation in Dalarna results from the heritage procedure, were land is divided between all of the inheritors.
To improve the consolidation large surveys in the consolidated villages in Dalarna are carried out. Many laws have to be followed due to the survey.
EKONOMISTYRNING I EN MOTORVERKSTAD: En analys av centralt ställda krav ur ett operationellt perspektiv
The purpose of this thesis is to analyze the design and function of an engine production management?s control system and its intended function, and to contrast it with the present management control systems in use on an operational level. Interviews conducted with employees from all levels of the engine production are the main source of this study?s empirical foundation. Information has also been gathered from relevant written material such as annual reports, internal documents etc.
Optimering av UA-Värde : Förbättring av en containerkonstruktion

The containers arethen leased to other companies, most often to pharmaceutical companies.Envirotainer are based in Lagga, Knivsta. It is also here where the production of thecontainers is held. The container RAP T2 was designed in the early 80ies. The RAPT2 contains a fleet of about 1220 containers spread all over the world.
Motivationsfaktorers relevans för medarbetarna på Sörmlands sparbank Vingåker : En kvalitativ studie
Bakgrund: I takt med att konsumenters preferenser har förändrats, har företag fått överge massproduktion till förmån för produktionssystem som bättre avspeglar konsumenternas ökade krav på flexibilitet. Ett sätt för att överbrygga denna utmaning är att implementera lean production. Även om detta sätt att producera på har tydliga fördelar för dagens företag, verkar lean production även kunna medföra problem i avseende på att kombinera med den befintliga, i många fall, traditionella styrningen i företaget. En del av styrningen som verkar vara speciellt svår att kombinera med implementeringen av lean production rör mätningen av produktionen. Vid en närmare granskning visar det sig att det råder vissa motsättningar mellan traditionell mätning och lean production som kan påverka företagets beslutsfattande negativt.
Statusbedömning av asynkronmotorer
Induction motors, often referred to as the workhorse of the industry, play an important role in production today. Therefore, it's important to diagnose any faulty induction motor prior to failure to avoid costly and time consuming production stops.This thesis compares methods for diagnosing induction motors in operation, MCSA, Park's vector approach and the standard method used by Swedish industries today. By simulating broken rotor bars and short-circuit in one of the windings, each method is tested and the results are compared using matlab.The results need further verification due to uncertainties of the condition of the test motor, even though the experiment gives a hint of the different advantages of each method. A combination of the methods should be able to tell if the motor needs further examination..
Kartläggning av energianvändning under byggfasen vid nyproduktion av flerbostadshus
The energy consumption in the sectors of residential and public buildings is 40 % of the total energy consumption in Sweden. The main part, 85 %, of the energy use in these sectors is for operation of the buildings. The rest is used in the building process. When energy-efficiency measures are taken the energy use during the operation time decreases and the fraction of energy consumption during the building time increases. This project is carried out in cooperation with JM AB and concerns the energy use during the building time of production of blocks of flats at the building site.The main part of the electricity that is used during the production of apartment buildings goes into the heating of portacabins and illumination of the building during the construction phase.
Hur ett mindre bemanningsföretag kan organisera försäljning ? där fördelarna överväger nackdelarna
With the globalization, companies in the West chose to shift production to developing countries to cut down costs. This had a major impact when child labor and very poor working conditions in these factories were discovered and led many companies to take responsibility for their suppliers and the employees by adopting voluntary so-called Codes of Conduct.There is a subtle balance to enforce improvement of working conditions for employees at suppliers´ factories and to keep costs down. On the one hand, companies would like to conduct extensive audits at their suppliers to ensure code of conduct compliance and thus protect their legitimacy. On the other hand, audits are expensive so companies would like to minimize audits to keep costs down. Companies thus have to strike a delicate balance in relation to how many and what suppliers they choose to audit.

My aim in this case study has been to create a method for creature design to test this method in a production and evaluate the results. To achieve this I studied and analyzed the methods of three concept artists and illustrators named James Gurney, Neville Page and Iain McCaig. From the analysis of these artist´s methods, combined with my own personal experience, a new method was formed. To test this method a creature was designed based on directives given by a game design group in the process of creating a table top role playing game in a fictitious world. These directives where given for the creature´s role and its living conditions.
Optimering av SNCR-system i en biobränsleeldad panna : möjligheter till minskade NOx-utsläpp för ENA Energi
Emission of nitrogen oxides as well as carbon monoxides is an inevitable result of combustion. A Swedish law "Law of environmental fee for emissions of nitrogen oxides as a result of energy production" (lagen om miljöavgift på utsläpp av kväveoxider vid energiproduktion (SFS 1990:613)) controls the emission of NOx from energy production by a system of fees. The system has resulted in a strong approach toward less emissions of NOx among the energy production plants. High emission levels, today exceeding 52 mg/MJsupplied fuel, leads to costs for energy production companies. This paper examines possibilities to reduce the emissions of NOx by optimization of the SNCR-technique in a biofuel fired heat and power plant.
