The goal of thesis is to find a solution of a problem in organization Colour Group s. r. o. This problém consists in repeated loss of knowledge and apply the solution to specific business venture. The solution is in clearly defined procedures of implemented processes and installation an elements of a knowledge management. The main tool of this solution will leveraging existing ICT options. Outputs of this thesis mainly consist mapping and graphical representation of the processes involved and the design of a new proces The methodology used in this thesis is mainly based on the methodology of reengineering by T. Davenport and is complemented by additional indicators like: calculation of declarative knowledge, which used the workers, and that the organization will lose if the process of reengineering not happen.

Die Raumautomation (RA) umfasst die automatisierten Verschattungs-, Beleuchtungs- und Klimatisierungssysteme auf der Raumebene eines Gebäudes und ist ein bedeutender Einflussfaktor bei der Nachhaltigkeit von Gebäuden. Der Einfluss der RA auf die ökologischen, ökonomischen und sozialen Aspekte der Nachhaltigkeit eines Gebäudes sind Teil zahlreicher verschiedener Forschungsarbeiten. Allerdings wurde die Nachhaltigkeit der RA bei dem Entwurfsprozess der RA sowie bei der Anpassung und der Nachrüstung der RA selten bzw. nicht ausreichend erforscht. Für diese Forschungslücke wird in dieser Arbeit der Begriff funktionale Nachhaltigkeit des Engineerings und Reengineerings der RA sowie des resultierenden RA-Systems vorgestellt. Darunter werden die effiziente Einsetzbarkeit bzw. Wiederverwendbarkeit von RA-Geräten bei Szenarien des Engineerings und Reengineerings sowie die Wiederverwendbarkeit von aktuellen Engineeringdaten in verschiedenen Engineeringaufgaben im Laufe des Lebenszyklus eines Raumautomationssystems (RAS) verstanden. Ziel der vorliegenden Arbeit ist die Entwicklung eines Konzepts für eine flexible Roadmap inkl. der dazu benötigten Datenstruktur zur Sicherstellung und Verbesserung der funktionalen Nachhaltigkeit für Engineering und Reengineeringprozesse der RA sowie der daraus resultierenden RA-Systeme. Diese Roadmap kann als Teil einer kontinuierlichen Performance-Evaluation eingesetzt werden. Der Einsatz dieses Lösungsansatzes wird mit unterschiedlichen praxisrelevanten Ansatzpunkten (Szenarien) entlang des Lebenszyklus eines Raumautomationssystems geprüft. Als Baustein der Roadmap wird die Einsetzbarkeit existierender Technologien für den RA-Entwurf untersucht und die benötigten Erweiterungen bzw. die Entwicklung neuer Algorithmen für einen integralen Einsatz vorgestellt. Ein Schwerpunkt der neuen Algorithmen ist die Verbesserung der Anforderungsmodellierung und des Anforderungserfassungsprozesses der RA. Das neue Konzept der Anforderungsvarianten ermöglicht eine bessere Strukturierung der Anforderungen und die Modellierung der semantischen Bedeutung von zusammenhängenden Anforderungen sowie komplexeren Anforderungsaspekten wie Energieeeffizienzklassen (EEK). Verschiedene Algorithmen werden vorgestellt, welche die Modellierung, Ermittlung und Verwaltung von Anforderungsvarianten ermöglichen. Ein weiterer Fokuspunkt liegt in der Entwicklung von Ansätzen zur Unterstützung der Nutzer bei Reengineeringaufgaben. Dazu gehören Ansätze wie die auslöser-abhängige Ermittlung des anzupassenden Bereiches des RA-Systems bei unterschiedlichen Szenarienklassen, die Anpassung der unterschiedlichen Modellebenen bei verschiedenen Szenarien (z.B. zur Verbesserung der EEK) und ein Mechanismus zur Ermittlung des Erweiterungspotentials eines RAS. Die entwickelten Algorithmen, Verfahren und Modelle werden in Form von Unterstützungsfunktionen eines Tools zum automatischen RA-Entwurf prototypisch implementiert, in einen anpassbaren Prozessablauf eingesetzt und begleiten den Nutzer so bei verschiedenen Engineeringund Reengineeringaufgaben. / Room automation (RA) spans across important trades in a building, such as shading, lighting, heating, ventilation, and air conditioning. Although it addresses the room level, RA has a great impact on the sustainability of the building as a whole. The improvement of different aspects (environmental, economic, and social) of buildings' sustainability through the application of RA has been the objective of various research. However, there has been insufficient research regarding the sustainability of the RA itself during its planning, modification, and retrofit. A new concept regarding this research gap can be defined, namely the functional sustainability of the process of engineering and reengineering of RA as well as the resulting RA system. This new aspect of sustainability includes, on the one hand, the efficient deployment and reusability of RA devices during different engineering and reengineering use cases and on the other hand the efficient reusability of engineering data generated during the life cycle of the RA system. This work aims to develop a new concept for a flexible roadmap and the required data structures to support a functional sustainable and user-oriented engineering and reengineering of RA. The advisory component can be applied to different practical use cases during the life cycle of a room automation system. Different algorithmic components are defined as part of the component. The applicability of existing RA design technologies for the development of these algorithmic components is investigated. Based on this, necessary functional extensions of existing approaches or new approaches for the automated design and redesign of RA as part of the roadmap's components are introduced. The first part of the roadmap's algorithmic components aims to improve the quality of the requirement modeling and engineering of RA. A new concept, namely the requirement variant, is introduced. This concept improves the structuring of the requirement set and allows the modeling of semantic meaning behind interrelated requirements as well as complex forms of requirements, such as the energy efficiency class (EEC). Using this concept, various algorithms for the modeling, identification, and management of requirement variants are introduced. A variety of algorithms and courses of action to support the user with different reengineering tasks are introduced. This includes an approach to identify the part of the RA system that has to be modified, the modification of layers of the system model for different use cases (e.g. to improve the system's EEC); and a method to identify extension potential of a RA system. The introduced models, algorithms, and courses of action are implemented prototypically as user-support functions of a tool for the automated design of RA. These components of the roadmap are applied to different use cases through a flexible workflow and provide support to the user during different engineering and reengineering tasks.

This diploma thesis deals with the issue of packaging management. Using methods employed in logistics and modeling tool ARIS, the analysis will examine the current situation and its related problem areas. Subsequently, there will be designed such a management concept that would eliminate these areas in order to make the management process streamline, automate and to lead to overall reduction in logistics costs.

Thesis (MBA)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: Samancor Chrome is an integrated ferrochrome producer with an estimated annual ferrochrome capacity of 1.26 million tons, or approximately twenty-five per cent of total Western world capacity in 1997. A decline in commodity pricing and other factors prompted Samancor to initiate a business process reengineering (BPR) programme facilitated by McKinsey and Company in the Chrome Alloys Division in 1997. The process however, met with considerable resistance from the Unions within Samancor Chrome, although several strategies were employed to promote acceptance of the process. The technical report assesses the effect of strategies utilised to lessen resistance to change during the business process reengineering programme initiated in Samancor Chrome. The assessment reviewed strategies given in relevant literature to lessen resistance to business reengineering processes and considered the applicability of such strategies within the context of Samancor Chrome. Research data was obtained through semi-structured interviews with Samancor Chrome senior management. The research showed that Samancor Chrome had formulated a communication and a participation strategy in preparation of the BPR programme. The strategies were the only acceptance strategies suggested by McKinsey and Company in their role as the BPR consultants. The context provided by the literature research showed that the participation strategy and the formulation of the communication strategy were inappropriate within the organisational context of Samancor Chrome. Conclusions regarding the situational validity of the strategies were supported by the failure of the strategies to reduce resistance against the BPR programme. A negotiation strategy was ultimately used as an acceptance strategy during the BPR programme, and contextual analysis showed the strategy to be appropriate although only partially effective as implementation was still delayed. Interpretative analysis of the research data indicated that a change management strategy for future BPR initiatives should rather contain elements of education, communication, retrenchment avoidance measures and consultation or negotiation within a management led, top-down approach. Management should drive the BPR process in an emphatic manner, with the programme execution and implementation being completed within a four to six month short time frame. / AFRIKAANSE OPSOMMING: Samancor Chroom is 'n ge-integreerde ferrochroom produsent met 'n geskatte kapasiteit van 1.26 miljoen ton per annum, of ongeveer vyf en twintig persent van die totale Westerse wêreld kapasiteit in 1997. 'n Reële verlaging in kommoditeits pryse sowel as ander faktore het daartoe gelei dat Samancor Chroom in 1997 'n besigheids proses herontwerp oefening onder leiding van McKinsey and Company in die Chroom Allooi Divisie geinisieer het. Die proses is egter deur die Unies binne Samancor weerstaan, alhoewel verskeie strategieë gebruik was om aanvaarding van die proses te bewerkstellig. Die tegniese verslag evalueer die effektiwiteit van die strategieë wat toegepas was om weerstand teen verandering tydens die besigheids proses herontwerp (BPH) in Samancor Chroom te verminder. Die evaluasie neem ook strategieë vanuit toepaslike literatuur om weerstand tydens besigheids proses herontwerp programme te verminder in ag, en oorweeg die toepaslikheid van die strategieë in die konteks van Samancor Chroom. Navorsings inligting is ingesamel deur semi-gestruktureerde onderhoude met Samancor senior bestuurs personeel. Die navorsing dui daarop dat Samancor Chroom kommunikasie en deelnemenings strategieë in voorbereiding vir die BPH program ontwikkel het. Die strategieë was ook die enigste strategieë wat deur McKinsey and Company in hul rol as BPH konsultante voorgestel was. Die konteks deur die literatuur studie geskep, het aangedui dat die deelnemings strategie sowel as die formulering van die kommunikasie strategie onvanpas was binne die organisatoriese konteks van Samancor Chroom. Gevolgtrekkings aangaande die situasionele validiteit van die strategieë was ondersteun deur die faling van die strategieë om weerstand teen die BPH program te verminder. 'n Onderhandelings strategie is uiteindelik as 'n aanvaardings strategie tydens die BPH program toegepas, en konteks analise dui die strategie as toepaslik aan alhoewel slegs gedeeltelik suksesvol, aangesien die program implementasie vertraag was. Interpretiewe analise van die navorsings inligting dui aan dat 'n veranderings strategie vir toekomstige BPH initiatiewe elemente van opleiding, kommunikasie, inkorting vermyding maatreëls en konsultasie of onderhandeling binne 'n bestuurs gedrewe program benadering moet bevat. Die program moet sonder vertraging gedryf word, met program voltooing en implementering tussen vier tot ses maande.

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Deutsche Telekom is operating various communication satellites since 1989. The SCC (spacecraft control center) is located near Frankfurt / Germany. The entire system is based on antenna/RF equipment, baseband and computer software packages running on a computer network of different machines. Due to increased maintenance effort the old baseband system needed to be replaced. This also had effects to the computer system, especially to the M&C. The aim was to design the entire system in a way that the operation effort in costs aspects and human intervention are minimized. This paper shows the successful real world project of reengineering a traditional spacecraft control center (SCC). It is shown how a fifteen year old hardware (baseband system) and software design was replaced by a modern concept during normal operations. The new software packages execute all necessary tasks for spacecraft- and ground station control. The Monitor and Control System (M&C) is a database driven design (FRAMTEC, from CAM Germany).

The “Software as a Service” model in service-oriented computing allows loosely coupled software components to be designed and integrated with other software systems. Web services, together with service-oriented architectures, are promising integration technology to facilitate legacy system Webification. However, since most components in a legacy system were not designed and developed as services, the current software systems need to be converted into a set of loosely coupled services. Therefore, a service-oriented software reengineering process is essential for legacy systems to survive in the service-oriented computing environment. In this service-oriented software reengineering process, understanding, decomposing and reusing legacy code turn to be important activities. In this thesis, a methodology for Service-Oriented Software Reengineering (SOSR) is proposed to support the identification, extraction and integration of reusable legacy code. According to both the result of legacy system assessment and a service-oriented analysis and design process, a reengineering decision is made by proposed rules. Based on the service-oriented software reengineering decision, ontologies for SOSR, which consists of Domain Concept Ontology (DCO), Functionality Ontology (FO) and Software Component Ontology (SCO), are developed by the ontology development methodologies. These ontologies store knowledge on both application domain and code entities, which support further legacy code analysis. The identification of service candidates in legacy systems is achieved by mapping FO and SCO via a novel method combining Formal Concept Analysis (FCA) and Relational Concept Analysis (RCA). After the service candidates are identified, the reusable legacy code is extracted by dependency analysis and program slicing. Some rules are defined in code query language for the detection of dead code. Program slicing techniques are applied as main reverse engineering techniques to recover executable legacy code. An Executable Union Slicing (EUS) algorithm is defined to generate executable legacy components with high cohesion and low coupling properties. In the integration phase, extracted legacy components with core legacy code can either be wrapped into Web services for the service orchestration in the business layer, or be composed in a software service provider. The proposed SOSR methodology is proved flexible and practical to migrate legacy applications to service-oriented architectures by the case studies. It can be customised according to different legacy systems. This methodology can help software developers and maintainers to reengineer the tightly coupled legacy information systems to the loosely coupled and agile information systems.
