ABB Gate Model : En processledningsmetod för ABB:s produktutveckling

Organisations tend to focus more and more on product and process development to increase their competitiveness. Several major organisations, among them ABB, have developed models aimed to more effectively control and manage product development processes. ABB is using its standardised model ABB Gate Model for this. The purpose of this thesis is to analyze how the introduction of ABB Gate Model has affected the outcome of decisions and also the decision-making in the product development process. The study is limited to elucidate the version of ABB Gate Model handling product development projects.

EKONOMISTYRNING AV BUTIKSVERKSAMHET: ? en fallstudie av modeföretaget ?Alfa?

The aim of this thesis is to examine how salesperson control can be exercised in a retail store environment. A case study has been performed on a Swedish fashion company emphasizing the relationship between the company?s upper level management and their retail store operations in order to describe, analyze and classify the prevailing management control mechanisms. The paper presents an agency theoretical approach to the relationship applying behavior- and outcome based control theory, performance measurement theory and incentives theory in order to give a comprehensive image of the control system. The main finding is that the company?s management control system as applied to the sales force in its retail stores can be categorized as mainly behavior-based despite several explicit outcome-based features..

Capacity studies on DeLavals sort gate DSG10

In the dairy production it is necessary to be able to sort cows. Dairy cows are sorted for many different reasons i.e. regrouping into production strings or for treatments i.e. inseminations, pregnancy and health checks, vaccinations or hoof trimmings. One labour saving way of conducting sorting is by using an automatic sort gate.

Inkongruenta styrmodeller: En fallstudie av reparation och underhåll i ett industriföretag

In theory, the management control of maintenance functions is described as problematic due to the nature of the work performed in the unit. The purpose of this thesis is to examine these predicted problems in practice. Further,the thesis aims at identifying how these control problems may affect the relationships between the maintenance department and its internal customers. A case study has been conducted in one of Sweden?s largest industrial companies to investigate the said control problems in practice.

Locus of control, syskonplacering och kön : Finns det några samband?

The purpose of this study was to examine if there was a relation between birth order, gender and locus of control. There where 162 participants in the study, 44 men, 115 women. Birth order was coded into three levels. There where no significant differences between birth order and locus of control. The result showed that female participants where more external when it came to locus of control.

Betydelsen av samhälleliga och historiska kontexter för sekters uppkomst : en jämförande studie av Peoples Temple, Heavens Gate och Soltempelorden

Syftet med denna litteraturstudie är att finna samhälleliga och historiska kontexter som sammanbinder Peoples Temple, Heavens Gate och Soltempelorden. Definitioner och beskrivningar av sekter, manipulativa sekter och karismatiska ledare presenteras. Fokus ligger på vilka likheter och skillnader som finns i deras uppbyggnad och tro, hur samhället såg ut när dessa sekter uppstod och om man kan finna några gemensamma nämnare när det gäller självmorden, alternativt morden.Peoples Temple, Heavens Gate och Soltempelorden har alla något gemensamt. De iscensatte tre av historiens största religiösa tragedier genom tiderna. Alla tre sekterna lämnade jordens yta genom att medlemmarna tillsammans med ledarna begick självmord för att komma till en bättre värld.Alla tre sekternas självmord kantades av samhällets motstånd och det finns historiska incidenter som kan ha att göra med grundandet av dessa grupper.

Effektiv prestationsmätning : en studie av prestationsmätning i kund-leverantörsrelationer

Background: Performance measurement as a management control tool has received considerable academic attention. As the number of inter-organisational relationships, such as customer-supplier relationships, increases, there is a new scope for performance measurement as a management control tool. In order for a company to assess the effectiveness of its supplier relationships it has to define, measure and evaluate variables that are critical for the success of the relationship. The role of management control, and thereby of performance measurement, has increasingly been discussed in theory. However, empirical research in this area is still somewhat limited.

Utvärdering av Field-Programmable Gate Array (FPGA) som hjälpprocessor för prestandaökning

Det här arbetet är en utvärdering om huruvida det finns problem som kan få en prestandavinst då man använder en Field-Programmable Gate Array (FPGA) som hjälpprocessor till en mikroprocessor i jämförelse men att enbart använda en mikro-processor. För att avgöra detta implementerades algoritmen gaussfiltrering dels på en mikroprocessor med språket C och dels för en FPGA med hårdvarubeskrivningsspråket Very-High-Speed Integrated Circuits Hardware Description Language (VHDL). Simuleringar gjordes för dessa två implementationer och resultatet visade att det var möjligt att få en prestandaökning på 25 gånger för denna speciella algoritm..

Utveckling av modellbaserad reglering i kommersiella styrsystem

In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.
