A model predictive control approach to generator maintenance schedulingEkpenyong, Uduakobong Edet 22 September 2011 (has links)
The maintenance schedule of generators in power plants needs to match the electricity demand and needs to ensure the reliability of the power plant at a minimum cost of operation. In this study, a comparison is made between the modified generator maintenance scheduling model and the classic generator maintenance scheduling model using the reliability objective functions. Both models are applied to a 21-unit test system, and the results show that the modified generator maintenance scheduling model gives better and more reliable solutions than the regular generator maintenance scheduling model. The better results of the modified generator maintenance scheduling model are due the modified and additional constraints in the modified generator maintenance scheduling model. Due to the reliable results of the modified generator maintenance scheduling model, a robust model is formulated using the economic cost objective function. The model includes modified crew and maintenance window constraints, with some additional constraints such as the relationship constraints among the variables. To illustrate the robustness of the formulated GMS model, the maintenance of the Arnot power plant in South Africa is scheduled with open-loop and closed-loop controllers. Both controllers satisfy all the constraints but the closed-loop results are better than the open-loop results. AFRIKAANS : Die onderhoudskedule vir kragopwekkers (OSK) in kragstasies moet kan voorsien in die vraag na elektrisiteit en moet die betroubaarheid van die kragstasie teen ’n minimum operasiekoste verseker. In hierdie studie word die betroubaarheidsdoelwitfunksie gebruik om ’n gewysigde onderhoudskeduleringsmodel vir kragopwekkers te vergelyk met die konvensionele onderhoudskeduleringsmodel. Beide modelle word toegepas op 'n 21-eenheid-toetsstelsel, en die resultate toon dat die gewysigde model ’n beter en meer betroubare oplossing bied as die konvensionele model. Die beter resultate van die gewysigde model is die gevolg van die gewysigde en bykomende beperkings in die gewysigde model. As gevolg van die betroubare resultate van die gewysigde onderhoudskeduleringsmodel word die koste-ekonomie-doelwitfunksie gebruik om ’n robuuste model te formuleer. Die model sluit gewysigde bemanning- en onderhoudvensterbeperkings in, met ’n paar bykomende beperkings soos die verhoudingsbeperkings tussen die veranderlikes. Om die robuustheid van die geformuleerde OSK-model te illustreer word die instandhouding van die Arnot kragstasie in Suid-Afrika geskeduleer met oop- en geslotelus-beheerders. Beide beheerders voldoen aan al die beperkinge, maar die geslotelusresultate is beter as die ooplusresultate. / Dissertation (MSc)--University of Pretoria, 2011. / Electrical, Electronic and Computer Engineering / Unrestricted

Proces ratifikace Rámcové úmluvy o kontrole tabáku / Ratification Process of the WHO Framework Convention on Tobacco ControlHerberová, Kamila January 2012 (has links)
The diploma thesis deals with the ratification process of the WHO Framework Convention on Tobacco Control in the Czech Republic. The proposal of ratification was denied by the Senate of the Parliament of the Czech Republic in 2005 and it was postponed. The debate was renewed in 2011 when the proposal was approved by both chamber of the Parliament of the Czech Republic and subsequently in May 2012 it was signed by the President of the Czech Republic. The thesis investigated different views of Members of Parliament on the ratification of the framework convention. To fulfil the aims of the thesis the Framework analysis method is used. The method reveals the competing frames in 2005 and 2011. Both periods are then compared. The author also tried to understand why the proposal in 2005 was denied and she offered one of the possible interpretations. The thesis is supplemented by chapters which describe the Framework Convention on Tobacco Control and the development of the ratification process. These parts use the interviews made with experts in the research area.

The thesis deals with the current topic quality control in the auditing profession. The quality of audit services is under the international harmonization as well as the financial reporting to achieve the results of audit procedures to be internatinally comparable. The thesis is very closely focused on the form and performace of quality control of Czech audit entities done by the independent authority The Chamber of Auditors of the Czech Republic, respectively by the control entiy named Supervisory Committee. The aim of the thesis is to verify the hypothesis related to year-on-year increase in audit procedures and the audit file quality with the assumption that the increase of quality is enhanced by the quality control from the side of internal or external quality controller. The hypothesis is at the end of the thesis verified as a reset of the practical part of the thesis in which is analyzed and assessed quality of specific audit file. The audit file was chosen intentionally for the purpose of the aim of thesis, to compare the quality of audit file before and after the internal quality control. The result of this comparison is that the quality of audit procesuders and audit file is strongly positively dependent on the quality control and performace of quality control is effective.

The aim of my thesis is the evaluation of tax audit issues and eventually to propose changes de lege ferendae. At the same time I apply the principles of tax audit in its selected aspects. The main aim of the thesis - a complex evaluation of the tax audit - achieved through partial commentaries and evaluations, which are reflected in the titles of each chapter and by using scientific methods such as descriptive method, the method of deduction and applications, as well as the synthesis method and the method of subjective criticism. The logical structure of my thesis is accurately represented by the structure of its seven chapters and several subchapters and its names. In the first chapter I discuss the institute of tax audit in general. In the second chapter I discuss the principles that need to be applied to institute of tax audit. The third chapter deals with stages of tax audits. The fourth chapter is reserved to protection during and after tax audit. Criminal context of tax audit is discussed in fifth chapter. Statistics of tax audit and my conclusions deducted from the statistic data are focused in the sixth chapter. The case law on the tax audit is focused in the seventh chapter. Processing of each chapter is accompanied by my subjective evaluations of individual aspects of the tax audit,...

Faktore wat die effektiewe bestuur en kontrole van skoolfinansies in openbare skole beïnvloedJordaan, Johannes Cornelius 27 June 2009 (has links)
AFRIKAANS : Voor 1994 was die skoolhoof aanspreeklik vir die beheer van die finansies van die skool. Met die instelling van die Suid-Afrikaanse Skolewet no. 84 van 1996 het die aanspreeklikheid ten opsigte van finansies drasties verander deurdat selfbestuur by skole geïmplementeer is. Daar bestaan groot onduidelikhede by departementele amptenare sowel as by skoolhoofde en beheerliggaamlede oor wie aanspreeklik vir die finansies van die skool is. Skole se begrotings het sedert 1994 van `n paar honderd duisend rand na `n paar miljoen rand toegeneem; meer personeel word aangestel wat deur die skoolbeheerliggaam vergoed word en dit alles plaas ekstra belading op die skoolhoof. Dikwels is die skoolhoofde en skoolbeheerliggaamlede nie opgelei om hierdie ekstra finansiële lading te hanteer nie. Daar word van die skoolbestuurspan verwag om kennis van finansiële bestuur te hê om hulle taak effektief te kan uitvoer, nie alleenlik vir hulle eie oorlewing nie maar ook tot die voordeel van die skool en die gemeenskap. Die doel van hierdie studie is om te bepaal watter faktore die beheer en bestuur van skoolfinansies in `n openbare skool beïnvloed en om `n model daar te stel wat die beheer en bestuur van skoolfinansies in `n openbare skool sal rig. ENGLISH : Before 1994 the principal of a school was accountable for the control of the school`s finances. Since the introduction of the South African Schools Act no. 84 of 1996 and the implementation of self management of schools, the accountability regarding finances has changed dramatically. Schools’ budgets have increased from thousands of rand to millions of rand since 1994; more teachers are being appointed and paid by the school governing body. Departmental officials, principals and school governing body members have no experience to handle the extra financial burden. Principals and school governing body members have no experience of carrying this extra financial burden. It is expected of school managers to have knowledge of financial management to enable them to execute tasks effectively, not only for their own survival but also in the best interest of the school and the community. The purpose of this study is to determine factors that influence the control and management of public schools’ finances and to present a model that will guide the control and management of a public school’s finances.
