Påverkan mellan ekonomistyrningen och inköpsfunktionen : En studie av Sandvik och Scania
AbstractTitle:The Impact of Management Control Systems on the Purchaser Function - A study of Scania and Sandvik Authors: Mohammad Reza Akhbari and Johanna Sullivan Svensson Published: 2011 Keywords: Management control, purchasing function, impact, control, control instruments, Key Performance Indicators, measurement, communication and organizational structure. Background and problem formulation: In order for a company?s business idea or vision to be fulfilled, the management of a company needs assistance from various means to intentionally affect the operation in the desired direction. Management control concerns activities of both financial and non-financial character in order to implement the strategy of a company and to reach profitability. Since the purchaser function is responsible of spending 50 percent of a company?s total revenue, the function has an optimal starting point to be a key actor in the shaping and execution of a company?s strategic plan.
Aktiv bullerdämpning i ventilationssystem
Active headsets have been on the market for years and now it is time for
something else to enter the stage. The technology of active noise reduction can
for exmple also be used in ventilation systems for reducing ventilation noise.
An active control system principally consists of four important components,
namely the downstream error microphone, the upstream detection or reference
microphone, the digital signal processor (DSP) and a loudspeaker.
The upstream reference microphone listen to the primary ventilation noise and
sends it to the DSP which makes a phase shift to the signal and sends it to the
loudspeaker. The loudspeaker sends out the opposite waveform of the incoming
one and reduce the primary ventilation noise.
Kvarteret Flaggskepparen, Industriellt byggande för offentligt ägda bostäder -En fallstudie i samarbete med NCC Komponent och MKB
The primary focus of this Master thesis is to study how industrial house building can be implemented during production of rental flats under the terms of public procurement. In order to determine a suitable working process as well as presenting a possible architectonic result of the process, a case study is carried through.A housing projekt is designed on a site i Malmö, where the commisioner is MKB Fastighets AB and the contractor is NCC Komponent with the industrial building system NCC Komplett. The focus of the design is to accomplish high quality apartments to a resonable price, as well as solving the overall scheme for the site.The housing projekt, Kv. Flaggskepparen, built on the consept of a single house model, used to handle the entire site, shows that the building system is well suited to accomodate the commisioners demands.In order to reach the best possible architectonic result with the building system, cooperation initiatded in an early stage of the process is neccesary.A model is proposed to handle the situation under the terms of public procurement. The model suggest that the geometrical design is mainly carried out after inquiry and that architectonic qualities should mainly be defined in a non geometrial way for inquiry..

Prestanda och precision pa? en enkortsdator i ett system med realtidskrav
The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.
Automatisk räkning med monokrom visionsteknik
The use of vision applications are growing and the demand for integration and connectivity with other industrial automation control devices is increasing. Some businesses that are using vision technology follow US Food and Drugs Administration (FDA) regulation concerning audit trail. This thesis investigates the possibility to use vision technology for counting objects, achieving connectivity and to follow FDAs audit trail regulation. A market survey has been used to select suitable hardware and software to be used in the design of an application that is able to count objects and that uses standard industrial network connection i.e. OPC data access and Microsoft?s .NET components over Ethernet.
Avståndets inverkan på styrningen: -en fallstudie hos Vin & Sprit
The aim of this thesis is to get a better understanding of how the management control system works at V&S Distillers. V&S Distillers went through an organizational change in the beginning of 2005. The marketing function went from being a country-driven to a category-driven organization. Among other things this resulted in increased cooperation between employees in different geographical locations. We aim to analyze how a geographical distance affects relations and the use of management control.
Missilstyrning med Model Predictive Control
This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.
Modellering av reserv- och nödkraftsystem i JAS 39 Gripen
Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.

Ekonomistyrning inom äldreomsorgen, Intraprenad eller entreprenad - är det någon skillnad
In recent years the elderly care in Sweden has gone through several structural changes with the main purpose of delivering a more efficient service. The aim of this study is to compare the management control system in a privately and a publicly managed elderly home. A qualitative study was conducted which included interviews, observations of meetings and reviews of relevant documents. To be able to identify possible differences the framework of Hood consisting of seven dimensions was used. An analysis of the selected dimensions showed that the differences in management control were minimal and Brunsson's theory of politicization and 'company-ization' were used to explain why..

Struktur och styrning med balanced scorecard som styrverktyg : En studie inom Västra Götalandsregionen
BackgroundThere are different organizational structures and control and it has been proved difficult to find a combination between these that leads to goal congruence and improved efficiency. An organization can be structured according to hierarchical levels and the decision making can be either centralized or decentralized. Organizational control can be classified according to the amount of rules and balanced scorecard can be used to weld together the structure with the control.PurposeThe purpose is to create an understanding of how two types of structures and control in an organization appears and also to investigate how these differ from one another concerning the balanced scorecard as a control system. We will also investigate how the variables goal congruence and efficiency are affected by the implementation of the balanced scorecard.MethodTo answer the purpose of this thesis we have mainly used the qualitative method since we have studied two organizations thoroughly through interviews on different levels of the organization. The study also has some quantitative elements since we wanted to get a more truthful picture of the organizations.
En studie av en hälsointervention mot stress, ohälsa och sjukfrånvaro bland kundtjänstanställda
The aim of this study was to investigate a health intervention at a Swedish telecom company, with regards to behavioral, cognitive and somatic stress, experienced health, and absence due to illness. A further aim was to investigate the employees' perceptions regarding the health intervention. Questionnaires were collected from 139 employees at the customer service departments.Results indicated that the health activity bowling to some extent could predict lower behavioral stress. However, the most important predictors of stress and perceived health were lack of meaningfulness and quantitative demands. Lack of meaningfulness was also a predictor of absence due to illness.
Pneumatiska artificiella muskler : med hjälp av en robotarm
According to the study [1] several firefighters are killed in action each year. This happens naturally in various ways. One of the major factors is that firefighters often do not know how the environment looks like, for example that a building in an industrial area contains hazardous gas cylinders. Without a solution, fire-fighters will continue to die in duty. It is therefore important to solve this problem so that we can minimize the risks and save lives.The goal of this project was a control system for pneumatic artificial muscles.
