Att reducera ledtiden i en produktion med hög variation och låg volym - En casestudie på Lab.gruppen
Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.
Foderhäckar till hästar i lösdrift :
Knowledge about feed racks for feeding forages to horses is lacking. Racks for sheep and
cows are sometimes used for horses. Feeding roughage on the ground, or feeding silage bales
with the plastic and net still on, can bring on a lot of different problems. The opportunity to
control the hygienic quality is small and feed losses can be high.
The purpose of this experiment was to investigate how the eating behaviour and consumption
of horses were influenced by feeding racks of different constructions. Feed losses and changes
in chemical composition of the forage were also studied.
Det lutar mot Lean : En jämförelse av arbetet med- och effekterna av arbetet med Lean på ASSA AB med teoretiska kunskaper inom ämnesområdet.
Sammanfattning Datum: 2011-01-14 Kurs: Kandidatuppsats i företagsekonomi Lärosäte: Mälardalens högskola Akademi: Akademin för hållbar samhälls- och teknikutveckling Handledare: Lennart Bogg Examinator: Cecilia Lindh Författare: Wilhelm Moby och Pia Robson Nyckelord: Lean Production, implementering, effekter. Titel: Det lutar mot Lean ? en jämförelse av arbetet med- och effekterna av Lean Production på ASSA AB med teoretiska kunskaper inom ämnesområdet. Problemfrågor: Hur har ASSA AB gått tillväga för att införa Lean Production och vilka faktorer har varit avgörande?Vilka effekter har införandet av Lean Production givit verksamheten? Syfte: Den här studien ämnar undersöka och sedan jämföra arbetet med- och effekterna av Lean Production hos ASSA AB med teoretiska kunskaper inom ämnesområdet. Metod: Metoden är av kvalitativ karaktär och med hjälp av djupare litteraturstudier och en semi-strukturerad intervju ska studiens syfte uppfyllas. Slutsatser: Resultatet av den här studien kan sammanfattas med att det som framkommit i den empiriska undersökningen mycket väl överrensstämmer med det som sägs i den teoretiska referensramen. ASSA AB har först infört verktygen 5S och standardiserat arbetssätt, vilket möjliggjort införandet av andra verktyg såsom kanban. Inget av detta hade dock varit möjligt med ett lyckat resultat om inte personalen först blivit utbildade och en leankultur skapats.
Separator: Aktionsforskning i en dansproduktion där ledarskap undersöks samtidigt som en ny organisationsform introduceras
There is a common belief that the arts contain knowledge of creativity that can enrich the business world. Similarly, the arts are in need of additional support from the private sector and know-how of business practices. In short, there is a need for mutual understanding. With my background as a dancer paired with my studies at the Stockholm School of Economics I have taken the challenge of bringing the two worlds closer together. By changing a social system, like an organization, it is possible to get a better understanding of it.
Bergsbrunna södra : analys och programförslag
This final project includes an analysis and a programme proposal for the
area Bergsbrunna södra. The area is situated along the railway between
Uppsala ? Stockholm, just south of Uppsala city. A new railway station is
planned here, which make the area attractive as residential area.
There are several values to take into consideration when developing an
area. An extensive analysis and valuation may define and protect different
characters and values, and also find the places most suitable to build
upon.
The area consists of three separate characters of landscape: the wide open
cultivated fields, the hilly wooden ground and the more varying little valley.
There are visual, cultural, social and ecological values to preserve.
The south part of the area is woods with high natural values that borders
to a national park in the natural forest of Lunsen.
Att systematiskt hantera kunskap vid planering av ny infrastruktur : En fallstudie om skyfallsskador på riksväg 90 i Kramfors kommun
Natural disasters are becoming more common due to climate change and it is important to adapt the society and its infrastructure to withstand events such as extreme rainfall. Precipitation is an important climatic factor affecting the transport and annually generates the cost of millions in damages, over the past 40 years heavy rain has increased and will continue to increase in the future. The extreme rainfall that occurred in Kramfors municipality in September 2013 led to flooding and destroyed several roads, including highway 90, which recently both had been rebuilt and given a new stretch of road. Extreme rainfall had also occurred in the municipality earlier. The aim of the thesis was to examine how the Swedish Transport Administration handles new knowledge gained after natural disasters and how this is used in the planning of new roads.
Flödesanalys av plåtsammansättning : Strävan mot Just-In-Time och minskat slöseri
The Volvo Trucks plant in Umeå is a highy complex manufacturing facility where the same production line handles a variety of different models. This require flexible and agile processes with high quality standards. This thesis studies the flow of material through a production line and how Volvo can use their existing manufacturing monitoring system to optimize the flow of materials.The goal with the thesis is to identify eventual problems with the flow of materials and to deliver a few proposals on how the production line can improve its productivity. The theory of LEAN, Just-In-Time and Supply Chain Management serves as the scientific reference to this project. By analyzing the flow of material, performing interviews and observing the processes a few problems are identified.
Optimering av OTEC-system
Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.
Förföljelse på grund av kön : En analys av hur kön som skyddsgrund tillvaratar kvinnors skyddsbehov
In the school subject of the natural sciences it is imperative that the students are given opportunities to ?talk science?, since the dialogues that occur in the classroom have a significant importance for the students? abilities to engage in meaning-making in their learning process. Hence, the student and teacher interaction in the classroom and the feedback given there play a significant role in the students? learning process. The aim of this study is to contribute to the development of formative assessment tools that can mediate the students? meaning-making in natural sciences subjects in upper-secondary school.
Fotoindexering på Jämtlands läns museum
The aim of this thesis is to describe the subject indexing of images performed at the provincial museum of Jämtland and to evaluate the inter-indexer consistency at the museum. The main questions are: How are photographs indexed in the database SOFIE foto regarding Outline-codes, subject headings and natural language keywords? How does these procedures compare to research and indexing projects? How consistent are the indexers at the museum when choosing Outline-codes, subject headings and natural language keywords? Answers are sought by reading articles about classification, image indexing, indexing language, indexing consistency and by looking at a number of projects attempting to standardise image indexing practice in Sweden. The indexing practice at the museum is also described. In addition a minor inter-indexing consistency study, based on the subject indexing of ten photographs made by five indexers at the museum, is performed.
Sammankoppling av fjärrvärmenäten i Nyköping och Oxelösund : miljö- och systemkonsekvenser
District heating covers most of the residential areas and industries in the twoneighbouring Swedish municipalities Nyköping and Oxelösund. In Nyköping,Vattenfall AB Värme produces heat in a bio-fuelled CHP plant. In Oxelösund,waste heat and use of waste gases from the steel production at SSABOxelösund is the basis in the district heating system.This report examines the environmental consequences of a connection betweenthe two district heating systems. A broad system approach is used and the focusis on environmental effects in the system.A system analysis has been performed on the result of simulations of differentheat and electricity production alternatives. The alternatives simulated wereone where Vattenfall Nyköping covers the base load in the joint district heatingsystem and two where the power plant at SSAB Oxelösund supplies the heatbase load.The conclusion in this report is that the consequences of connecting the twodistrict heating systems can be both positive and negative, depending onsystem boundaries and on the environmental focus.
Jämförelseförsök mellan ogräsharvning och radhackning :
The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010.
The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing.
In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment.
The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment.
Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..
Factors for success in Swedish biogas : a study based on the Swedish agricultural sector

Nybyggnad till fårproduktion :
In Sweden we need more lambs during March to June. I decided to calculate on a spring lamb
production, because to many of the Swedish lambs go to slaughter in the autumn. I counted on
1000 ewes which have 2000 lambs each year, 200 of these lambs stays on the farm and
replace old ewes. The buildings are 3600 square meters. I have counted on two different sorts
of buildings, the first one is a shed, the second one is three polytunnel sheephouses.
