Stabilitet och förändring i samband med en ERP-implementering : En fallstudie

Utvecklingen och användningen av ERP-system har blivit allt vanligare och trots att ett sådant system kan bidra med effektivitet kan implementeringen av ett sådant system innebära en omfattande organisatorisk förändring. Vid en förändring i form av införande av ny teknologi inverkar befintliga rutiner och institutioner på huruvida stabilitet kan upprätthållas. Stabilitet kan upprätthållas då nya regler går i linje med rådande rutiner eller vid närvaro av en lös koppling mellan dessa. Uppsatsens syfte är att genom en fallstudie undersöka om och isåfall hur stabilitet och förändring kan samverka vid implementering av ett ERP-system. Studien visar att detta är möjligt, dels tack vare att de anställda får vara delaktiga, att de inser förändringens huvudsakliga syfte samt att de nya reglerna går i linje med rådande rutiner och institutioner.

Effektiviseringspotential inom industrisektorn : Energibesparing vid frekvensstyrning av centrifugalpumpar ? en fallstudie

The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..

Systemtyper utanför ramen för både traditionell systemutveckling och e-infrastrukturutveckling : Finns de och hur bör de i så fall utvecklas?

Denna studie har som syfte att underso?ka om det finns en typ av system vars egenskaper liknar ba?de traditionella system och e-infrastrukturer utan att tillho?ra na?gon av dessa typer samt hur en designmodell skulle se ut fo?r denna typ av system. Detta system kallar vi gra?nsfallssystem.Fo?r att underso?ka om denna finns har traditionella system och e-infrastrukturer samt hur man utvecklar dessa typer av system analyserats. Detta fo?r att se ifall det existerar na?gon form av system som har egenskaper fra?n ba?da dessa ytterligheter och om det existerar sa?dana system hur man pa? ba?sta sa?tt ska utveckla dem.

Willingness-to-Support

The purpose of this thesis is to define and theorise willingness-to-support as a possible measurement of corporate reputation. The knowledge production in this thesis is done through reasoning with companies to gain a deeper understanding of the social world and the respondents? view of their reality. Grounded theory is used as an inspiration for conducting the research. A qualitative method is used in the form of semi-structured interviews with six companies in three different business sectors.

Uttagsbeskattning av en kooperativ förenings försäljning av el till självkostnadspris

The thesis has as purpose to describe and analyse a decision made be the Swedish tax committee in which it was decided that a cooperative economical associations selling price, which was less than the comparable public bonds market price, would be the focus of a withdrawal tax. There are exceptions from a withdrawal tax, that is if the transaction has a business motivation. However the concept, business motivation, is narrowly interpreted both in the preparatory works and in case law, which makes it irrelevant to the situation at hand. A cooperative economical association is a form of association nearest akin to the limited companies. These types of associations have as purpose to increase their owners wealth with the benefit of freedom from personal responsibility.

Borde Sverige gå från ett spelmonol till ett licenssystem gällande EMV lotterier? : En kostnadsnyttoanalys

The gambling industry goes from a national matter towards an international market. Since more and more members of EU does liberalise the gambling reforms and introduces a license system more participants will get an EU license for online gambling. With an EU license it is difficult for members of the EU to refuse a company to offer a gambling supply on the Internet if they don?t have an open license system. This paper tries to acknowledge the problem regarding the monopoly Sweden has today and calculate the effect if Sweden would move to a license system regarding online gambling by doing a cost benefit analysis.

Prestandaförändringen hos en bergvärmeanläggning efter fem års drifttid

The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge.The tenant-owner?s association Duvan at Petterslundsgatan in Uppsala installed year 1999-2000 a geothermal heating system. The purpose of this installation was that they hoped it would lead to a smaller usage of district heating which would lead to a reduction of the heating expenses for their buildings. The geothermal heating system consists of 19 energy wells and 4 geothermal heat pumps, and it is one of the first systems of that size in the region of Uppsala.

OSE och Linux : En studie om prestanda

There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

Hazel- Ett mjukvarusystem för automatisk och optimal schemaläggning

This report documents the development of a software system for automaticscheduling called Hazel. This system is comprised of a server where an automaticscheduler has been implemented, as well as a web and mobile applicationthat allows users to interact with the system. The scheduler hasbeen developed with the functional programming language Haskell and usesa SAT-solver.Manual scheduling has long been the bane of managers everywhere, asmatching the needs of the employer with those of the employee is often adifficult and time-consuming task. There already exists several automaticschedulers that attempt to solve this problem. The issue with said schedulersis that thay tend to be expensive, or developed to only fulfill the needsof a particular organisation.

Myndighetsattityder : En ethosanalys av Delegationen för romska frågor

The Authorities attitudes towards Gypsies have been characterized by prejudice for a long time. This has lead to the relief actions of the Authorities being formed by discriminating acts. In purpose of eliminating the discrimination of the Gypsies, the Delegation for Gypsy matters formulated a strategy for solving this problem in the report ?Gypsy rights ? a strategy for Gypsies in Sweden?. Despite the goodwill of the Authorities this report has been criticized by Gypsies in Sweden. In the investigation of the derivation of this criticism the aim of this essay is to look at how the Authorities attitude towards Gypsies is shown in this report and how it affects the creation of their ethos.

Price transmission dynamics of Chinese ADRs listed on the NYSE

Purpose: This study aims to examine the price transmission among ADRs (American Depositary Receipts) and their underlying shares, US market index and Hong Kong market index. We will attempt to capture how a shock in the home market is transmitted to the foreign (and vice versa). In addition we will attempt to assess the relative weight of each variable in the system generating unexpected variations of its own and other variables and at what speed the shocks are absorbed.Methodology: ADF unit root test, Johansen?s co-integration test, Granger causality test, VECM, impulse response, variance decomposition Empirical foundation: Five Chinese ADRs listed on the New York Stock Exchange. Each ADR represents a specific industry.

Fast i garderobsöppningen : En kritisk diskursanalys av VeckoRevyns representation av bi- och homosexuellas sex- och kärleksrelationer

The purpose of this study was to examine the ways in which the Swedish lifestyle magazine VeckoRevyn construct the sex and love relations of bi- and homosexuals. We analyzed 22 unique texts in magazines, from 2009 to 2014, in order to get a result as current as possible.To represent the magazine overall we have selected texts from various parts of the magazine. With a critical discourse analysis and through relevant and significant theories and perspectives such as social constructionism and heteronormativity, we found that VeckoRevyn represent sex and love relations of bi- and homosexuals through four discourses.The outcome of our study shows that VeckoRevyn only represent a limited part of bi- and homosexuals sex and love relations. In the analysed texts bi- and homosexuals are forced to ?come out of the closet? repeatedly and their sexual relations are rarely represented.
