Effektivitet i grundskolan - en studie om Leans applicerbarhet på processen utvecklingssamtal
Efficiency has become an important objective for many providers of welfare services. Among Swedish schools, both private and public, increased administrative demands seemingly influence operations, and affect teachers negatively through perceived stress. Simultaneously, Swedish students scored an all-time low in the latest PISA survey, and are now performing below the OECD-average in science, mathematics and reading. A central administrative task in the Swedish elementary school is the parent-teacher conference, which is an important activity in supporting the development of the student's knowledge and social skills. Lean is a well-established operations framework, which has proven successful in order to improve process efficiency.
Rening av avloppsvatten med anaerob membranbioreaktor och omvänd osmos
This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.
Flödesoptimering i begränsande resurs
Most companies have a bottleneck in their production, that is a constraining re-source. When the demand is higher than the capacity in the constraining resource it is impossible to produce the demanded output. This problem leads to delayed deliveries, unhappy customers and ultimately to decreased revenue. Bottlenecks therefore has a significant role in production and must be handled thereof.MW Power in Sävsjö, Sweden designs and manufactures water and steam boilers for the customer's unique needs. MW Power invested in a new plasma cutting ma-chine but the machine has not reached the expected capacity.
Tidsåtgång i mjölkproduktion under betessäsong : inflytande av besättningsstorlek, samt mekaniserings- och automatiseringsgrad
Time studies in dairy production are an essential tool when deciding about level of mechanisation and automatisation both in investment situation and improving efficiency in existing operations. In previous investigations such studies have been carried out during normal barn conditions during winter. Since there is a compulsory to have dairy cows grazing 3 to 5 months during summer time in Sweden time studies during this season is important to have a full picture of needed working time. During grazing season time studies was carried out at 14 dairy farms representing herd sizes from 66 to 450 dairy cows of which 6 farms with AMS. 8 farms were the same as studied during winter season.
En jämförelse av hästens tidsbudget och dygnsrytm : frilevande och i stall
Today it is common to have adult horses stabled for most of the day. This limits the horses? ability to perform some of their natural behaviors such as foraging and movement. The purpose of this review was to compare the feral horses? diurnal rhythm and time budget with stabled horses.
SMED implementation vid slipoperation
The thesis has investigated how Sandvik Coromant could implement the SMED principle on one of their grinders groups and what improvements it would lead to. The aim of the thesis is to identify the current situation and investigate how their setup times would be affected by SMED. The work initiated with a literature analysis about the SMED principles and then proceeded with an analysis of the current situation where the activity was time mapped. The analysis consisted of time trials of the process that the thesis would include. The time studies revealed opportunities for structural improvements to create environment for a more structured process.
Kartläggning av reparationsprocessen på Westermo Teleindustri AB : Identifiering av slöserier och förslag till förbättringar
This report is the result of a thesis performed at Westermo Industrial Ltd with its headquarters in Stora Sundby and it sums up the author's studies for University Engineering in Innovation, Production and Logistics at Mälardalen University.The main goal of the thesis was to identify problems and suggest actions that lead to the reduction of the repair time from 3 weeks to 2 weeks. The key questions that were answered in order to achieve the thesis objectives are: What are the biggest challenges that make the repair process time last for 3 weeks? What are the necessary means and measures in order to reduce the repair length to 2 weeks? The author adjusted the work to the Swedish repairs, repair issues that arise from sell unit Westermo Data Communications AB with its office in Västerås and performed the status report by mapping the repair process, through using observations, interviews and bibliography research studies.

Data that has been collected was analysed by the author and the decision to execute a workshop that affects Repair Department and Logistics was made.
A comparison of transporters? paddle use when unloading pigs at slaughter
Today, pigs are moved on farm, between farms, between countries and to abattoirs. This movement of live pigs requires handling practices that are designed for the purpose. The objective of this study was to research the use of paddle in moving pigs, to investigate if there were different methods of paddle practice, explore the time efficiency of different kinds of paddle use and if there were any time variations in methods that varied in intensity of touch. This study was done on two Swedish abattoirs for a total of five weeks. A total of 22 transporters working at two different abattoirs where studied during unloading of pigs at the abattoirs.
En fallstudie om effektivisering av kosthanteringen inom Nybro kommun
In December 2008 the municipal council in Nybro, decided that the municipality shouldreduce the budget for food service. The budget should be reduced by 2 100 000 SEK.They decided that the children- and education committee, and the care committee would haveto lower their budget with 1 264 000 SEK respectively 636 000 SEK. The change have to bedone under two years, 60 % should be done under 2009 and 40 % under 2010.As a result of the decision, many kitchens have to become kitchens that only serve food, notcook it. This will result in preschool staff and nursing staff take over some of the tasks fromthe kitchen staff. The municipal council also decided that entrepreneurs could take over one(later two) cooking areas.A kitchen that serves food means that there isn?t any cooking involved.
I BRÄNNPUNKTEN: Samhällsekonomisk utvärdering av arbetsmarknadsåtgärder. Illustrerad med hjälp av Brännpunkt i Kävlinge 2002-2005

Cykeltidsoptimering av sjuaxligt robotsystem
This master thesis studies how much the cycle time, i.e. the time it takes for an industrial robot to perform a given task, can be reduced if an extra degree of freedom (DOF) is added to the robot system. The extra DOF consists of a linear track, which is supposed to be used in an optimal way. The problem has been studied using simulations in the robot simulation tool RobotStudio. To be able to run an optimization in Matlab, with the RobotStudio simulation cycle time as the object function, communication between Matlab and RobotStudio has been set up with an interface written in Visual Basic.
