Påverkad strukturerad produktion produktiviteten? : Analys av mätningar från byggbranschen

The cost of construction projects have increased during the past few years. Different actors in the construction industry work together to advocate various measures to mitigate these cost increases. One of these measures is to try to improve the efficiency in the phase of production. By striving for a kind of standardization with a constant quest for improvement, the productivity can increase while the costs of production fall.For this thesis has a case study been conducted at the construction company JM AB which is seeking this. They call the approach structured production and have implemented various measures to achieve a more productive output.Based on information from reconciliations, the cost and the spent hours of craftsmen have been analyzed at the company where the case study took place.

Use Case : en teknik för att representera krav i RE-processen

Detta examensarbete ger en introduktion till Requirements Engineering (RE), kravprocessen i informationssystemutveckling. Det slutliga informationssystemet är i stor utsträckning beroende av en effektiv RE-process. Ett framgångsrikt informationssystem beror på hur väl det färdiga systemet stämmer överens med användarens och andra intressenters behov och förväntningar. Use Case är en teknik som kan användas i RE-processen för att representera krav. Arbetets syfte är att finna de för- och nackdelar som finns med Use Case för att representera krav.

Det är ingen slump, det handlar om klass : Om klasstillhörighetens relevans för klientens möjligheter och begränsningar i den svenska socialtjänsten

The aim of this study is to illuminate social worker?s perception of social class within the Swedish social service system. This study therefor examine if social class contributes to the production and reproduction of the client and what impact social class has on the interaction between client and social workers. The study was conducted with qualitative semi-structured interviews with social workers from three different departments of social service. The theoretical approach is Yeheskel Hasenfeld?s theory about moral practices in welfare organisations, Michael Lipsky and Roine Johansson?s theories about client construction and Pierre Bourdieu?s class theory.

Biologisk reducering av nitrat och nitrit i vatten

During the summer 2007 was a scrubber tested at Gruvön papper mill in Grums. The scrubber reduced NOx with 90 % in flue gas. NOx was transferred from the flue gas to a scrubber liquid as nitrate and nitrite. The scrubber liquid needs to be purified from nitrate and nitrite. One possible solution is to clean the scrubber liquid in Gruvön biologic cleaning construction.Microorganisms in the biologic cleaning construction need to assimilate nitrogen. There are environments free from oxygen in the cleaning construction.

Passivhus av helväggselement i träull

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

Informationssystem för service av truckar och städmaskiner

This paper describes the evolutionary development of an information system for a small company. The company performs overhaul of forklifts and cleaning machines. The company has already an information system that handles the reports from these overhauls but it needs a supplementary tool that assist the chief planner to plan forthcoming overhauls.It should be able to display coming overhauls in a timetable and eventually print them, either to a PDF file or to a document. The timetables this function produces will help the chief planner and the assemblers to get a good overview of their day-to-day work.The tool needs to be intelligent in that way that it takes into consideration were in the country different assignments will be performed. So that time consuming travels over great distances can be avoided.

EU:s tjänstedirektiv - ursprungsprincipen eller destinationsprincipen?

The Vaxholm conflict was initiated when the Swedish Trade Union for Construction Workers shut down a construction site in order to prevent a Latvian construction company to build a school after the two parties had failed to agree upon a collective agreement in compliance with Swedish regulations. An emotional public debate followed that resulted in a discussion of the proposal for the Services Directive of the EU, based upon the country-of-origin principle. In this thesis we will analyze whether the country-of-origin principle or the country-of-destination principle is best suited to capture the gains-of-trade that the common market hoards and improve welfare within the EU. We conclude that the country-of-origin principle is the more apt of the two, though it leads to some short-run costs such as structural unemployment. But these will be more than outweighed by the gains in aggregate welfare for the EU in the long run..

Äldre och rädslans paradox : Konstruktionen av hotets och rädslans samhälle

The aim of this thesis is to examine the fear of crime in old peoples lives. Notwithstanding that the age category is exposed to crime to a low degree, old people are experiencing a great fear of crime relative younger people. This is the paradox of fear, also recognized in gender studies. The question is how this paradox can be understood. To answer this, twelve elderly men and women have been interviewed and the reports about crime in the local newspaper, Norrköpings Tidningar, has been analyzed, through discourse analysis.The discursive construction of fear is here discussed in terms of discourses of a fearful society, and stereotypes of old age.

Tillval och anpassning : kundens valmöjligheter vid köp av nyproducerad bostadsrätt

Background: The real estate market has previously been subsidized by the government. The construction has been characterized by standardization and large scale complex. In the current situation there are other conditions on the real estate market, subsidies do not occur at the same degree and the market is more competitive. Customer influence has also changed.

Utvecklingen från traditionell ekonomistyrning till verksamhetsstyrning : En studie inom ekonomistyrning

This thesis primarily includes a study on whether companies can develop a mathematical activity that supports students' motivation in mathematics. The work was done together with Midroc Electro, a company that pays attention to the difficulty of recruiting and therefore was interested in investigating how the business world would be able to contribute.The thesis can be divided into three stages. The first part comprised by a exploration into research on student motivation regarding mathematics as well as numerous interviews with engineers to see how the research findings did fit with Midroc Electros reality. In these studies it became clear that the student who aims for a profession whose education or work requires math belongs to the group of students who primarily manage their studies in mathematics, that is, those that have the greatest motivation to work hard and complete their studies.Research information and interviews were compared and resulted in the thesis second part, Midroc Challenge. An activity where students primarily came to learn about the engineering profession and secondly how mathematics can be used in the engineering profession.

The authors met the first time in 2008, when they started their studies at Uppsala University. Since then they have completed various projects, both within and without the university. This study is based on a theory that was first conceived when Jonas Stenberg did his internship in the summer of 2010.

Investeringskalkyl baserad på ett flerbostadshus energiprestanda

The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..

Kartläggning och analys av tjänsteprocessen i IKEA-varuhus ur kundens perspektiv

This thesis has been done in collaboration with Peab Stockholm Building 3, which is a region within the Peab Sverige AB. The report is based on a survey and studies of Peab business management systems and production literature. For general information gathering has literature from well-known sources collected in libraries and through the Internet. It shows through the work that Peab has routines for experience feedback in the construction process, but that these procedures work in a small scale and the practical work experience feedback does not work at all. This is also something the construction industry in general also perceived as problematic. The questions in the report are of a wide scale and concerns construction errors cost, how the employees perceive that the company takes advantage of the skills and the mental stress in production line. The goal is to find how Peab Stockholm Building 3 will work on the experience feedback to allow for better productivity. In conclusion, the report author tries to demonstrate what can lead to increased productivity and improved work experience..
