Cloud Computing erfährt insbesondere im Bereich der Logistik seit mehreren Jahren eine zunehmende Bedeutung. So werden immer neue Anwendungsgebiete durch innovative Cloud Services erschlossen. Die zunehmende Spezialisierung und Fokussierung von Unternehmen auf ihre Kernkompetenzen und die Kooperation dieser mit anderen Unternehmen, um einen gemeinsamen, kollaborativen Geschäftsprozess durch Cloud-Services abzubilden und eine entsprechende Mehrwertdienstleistung zu erbringen, stellt die Unternehmen vor die Herausforderung, Daten bei gleichzeitiger Aufrechterhaltung der Privacy miteinander teilen zu müssen. Die vorliegende Arbeit leistet in diesem Forschungsfeld zwei Beiträge. Hierzu wird zunächst eine Sprache und ein Vorgehen zur Modellierung von Privacy-Anforderungen in solchen Geschäftsprozessen erarbeitet. Als zweiter wesentlicher Beitrag ist die erarbeitete Architektur für die Verwaltung und Ausführung eben dieser kollaborativen Geschäftsprozesse unter Aufrechterhaltung der Privacy zu sehen.

[Context] Interdisciplinary healthcare teams (IHTs) include practitioners from different disciplines who collaborate for providing care to patients. IHTs often follow clinical workflows composed of tasks that must be executed by practitioners with specific capabilities. The membership in an IHT can however evolve over time for a given patient. [Problem] Existing Business Process Management (BPM) suites and their workflow execution engines are designed for supporting and monitoring general workflows, but they are insufficient in supporting the allocation of tasks to the most suitable practitioners during the execution of healthcare workflows in a dynamic context. [Methodology] Using Design Science Research, this thesis builds on top of an existing semantic layer, which includes an ontology defining IHT team concepts and relationships that are used to reason automatically about team dynamics, in order to add dynamic team management to BPM suites. It does so by proposing and designing middleware (including a generic interface) that enables the semantic layer to command the BPM suite to allocate suitable practitioners to tasks during the execution of clinical workflows. The design and implementation of this middleware are discussed, and the latter is tested on a commercial BPM suite for two realistic clinical processes. [Results] The proof-of-concept implementation demonstrates the feasibility of using middleware with a generic interface to add support for IHT executing BPM suite when managing a patient. In addition, the thesis also demonstrates that the ontology used in the semantic layer is minimal, that is, all of its concepts and relationships are necessary for the required team functionalities (usually absent from BPM tools) to work properly.

Business process management is important topic in business information systems. Workflow systems are taking the top places in company information system architecture due to aspiration to make business process more and more optimized. This project is about parallel processing and implementation of business processes parallel processing in complex information systems. Content of this project is o function and object library for modeling business process in Vema, a. s. Workflow system. Important part of this project is parallel processing solution and its implementation.

Business process management (BPM) is a philosophical approach to organisation-wide management in which the focus is on the processes through which it operates, and in particular the streamlining and optimising of these processes, for which software solutions may be used. CTexT is an intrapreneurial software organisation that has been experiencing problems with software development due to a lack of formal processes relating to customer support, versioning, configuration, quality, risk and project management. The objective of the study is to determine whether the implementation of an electronic BPM system can effectively solve CTexT's development problems and thereby improve its overall software development capacity. More specifically, the focus is on i) the effect of the resulting standardisation on creativity and innovation, and ii) implementation matters, such as the type of processes that can be subjected to an electronic system, and how CTexT can overcome the time and cost constraints of such a system. The study investigates these questions by means of a literature investigation in combination with interviews with knowledgeable respondents from other innovative and software organisations. Interviews with six employees from CTexT determine the relevance of these findings and highlight critical areas for process improvement. Since BPM systems improve organisational efficiencies and are generally employed in larger corporate contexts marked by transactional and repetitive activities where they enforce administrative rules, the conclusion is drawn that a BPM system will not be suitable for an intrapreneurial organisation, and that it is likely to cause more disruption to the creative environment than improve its operations. It is further shown that although a BPM system is theoretically applicable to software development, it generally does not seem to be applied practically in the industry, and the suitability of this process as manageable through a BPM system is seriously questioned. Instead, the research points to improvement through the application of software development methodologies and a holistic approach towards BPM. The investigation at CTexT confirms that its development problems relate to flawed methodologies and that remedies should therefore focus on improving its methodologies and controlling certain aspects of the software development life cycle by means of suitable software tools. / Thesis (M.B.A.)--North-West University, Potchefstroom Campus, 2007

Η παρούσα εργασία εστιάζει στη διαδικασία δημιουργίας του χάρτη απωλειών ρεύματος της δέσμης ηλεκτρονίων κατά μήκος της Tρίτης Πειραματικής Διάταξης για το Συμπαγή Γραμμικό Επιταχυντή του Ευρωπαϊκού Κέντρου Πυρηνικών Ερευνών CERN (Beam Loss Map for Clic Test Facility 3). Ο χάρτης απωλειών χρησιμοποιείται για τον προσδιορισμό των σημείων στα οποία υπάρχει απώλεια ρεύματος των φορτίων της δέσμης. Ο προσδιορισμός των σημείων αυτών είναι πρωτεύουσας σημασίας, τόσο από θεωρητική όσο και από πρακτική πλευρά, επειδή πιθανές απώλειες συνεπάγονται αυξημένους κινδύνους έκθεσης σε ακτινοβολία για τον άνθρωπο, πιθανές βλάβες στα μαγνητικά στοιχεία, αλλά και μείωση της ισχύος της δέσμης. Στο πρώτο μέρος της εργασίας, παρουσιάζεται το Ευρωπαϊκό Κέντρο Πυρηνικών Ερευνών και οι πειραματικές εγκαταστάσεις στις οποίες έγινε η παρούσα εργασία. Στη συνέχεια, περιγράφεται η συλλογή και ανάλυση των δεδομένων με στόχο την χαρτογράφηση των σημείων απώλειας ρεύματος δέσμης στο σύμπλεγμα του CTF3. / The Diploma Thesis focuses on creating the Beam Loss Map for Compact Linear Collider Test Facility 3, at CERN. The goal of the project is the allocation of the points where beam current losses occur. Defining these points is of great importance, because any loss of beam current, especially at the maximum energy of 150 MeV, can induce radiation activation along the machine, which is dangerous for both the hardware and the personnel who need to service the machine. In the first part of the project, CERN, LHC and CLIC are presented. The second part contains data analysis, presentation of the calibration procedure of the BPMs, the new scaling factors and finally the Beam Loss Map for CTF3.
