Significant accidents are often related to the performance of a complex socio-technical system (enterprise) involving technology, people, organizations, processes, management and legislation. Approaches to identify factors that lead to accidents and then take them into account during the design, operation, maintenance and evolution of the socio-technical system (enterprise) are not well defined and not consistently utilized in practice. The emerging discipline of "enterprise engineering" provides an opportunity to apply an engineering approach to the design, operation, maintenance and evolution of enterprises to improve the likelihood of the enterprise achieving and maintaining its safety goals. The integration of design principles and approaches from the fields of systems engineering, safety engineering, management science and enterprise architecture into a Safety Enterprise Engineering (SEE) approach based on a consistent model of the enterprise provides the basis of the approach described in this thesis. A general process model for applying an enterprise engineering approach to safety management is defined. Design principles from nuclear industry best practice documents are identified and mapped to the general process model. The Fukushima nuclear accident that occurred in 2011 was used to identify weaknesses in current practices in the nuclear industry. These weaknesses were compared with best practices, as defined by International Atomic Energy Agency (IAEA) documents, to identify the subset of weaknesses identified from the Fukushima accident that are also weaknesses within the IAEA set of best practices. The Safety Enterprise Engineering approach was applied to a slice of safety related functionality of a CANDU nuclear utility to demonstrate the degree to which the SEE approach overcomes weaknesses of both current practice and best practice within the nuclear industry. / Thesis / Doctor of Philosophy (PhD)

Thesis (PhD) -- Stellenbosch University, 2014. / ENGLISH ABSTRACT: This thesis has as its focus the engineering of integrated knowledge networks (IKNs) through the use of a reference architecture. The purpose of the study is to gain a deeper understanding of the constructional principles underlying this class of collaborative networks. Although IKNs and enterprise engineering are both seen as promising approaches to the challenges of the Information Age, significant challenges still exist in the engineering of IKNs. Our globalised and commercialised society may currently be characterised by both extreme complexity and extreme rates of change. Enterprise engineering is seen as a promising approach to equip enterprises with the characteristics that are desirable in the modern economy, including flexibility and agility. Enterprise architecture contributes to this endeavour by providing a high-level design of the enterprise that allows for integrated engineering of the enterprise. From a commercial point of view, it has been widely recognised that the ability to innovate and generate new knowledge through the development of new products, services and processes is a key factor in the survival of enterprises. The latest trends in innovation management, however, show that the innovation process is no longer one that is executed inside a single enterprise, giving rise to the development of inter-organisational innovation networks. Furthermore, the importance of knowledge as a dynamic enabler of this networked innovation approach is highlighted. This has lead to the emergence of IKNs in which knowledge is created and shared between network stakeholders in order to foster sustainable innovation. The increasing rate of change means that enterprises, including IKNs, have progressively less time to react to market changes and opportunities. The emphasis is therefore on the potential of the EE and EA disciplines as tools to adapt to the dynamic landscape of the Information Age. At present, the ability to apply comprehensive enterprise engineering to IKNs is hampered by the lack of resources that describes sound constructional principles for these networks. The focus of this study is therefore on the application of the enterprise engineering discipline to IKNs through the development of a reference architecture. The reference architecture for IKNs is developed through design science research within a pragmatic and qualitative research strategy. The research problem is first identified and motivated. Various solution objectives are subsequently defined. This is followed by the design and development of the reference architecture through four iterative design cycles. A qualitative systematic review is conducted and serves as the foundation for the development of various reference models. The reference architecture for IKNs is demonstrated and evaluated through a series of illustrative scenarios, after which the utility, novelty and design rigour of the artefact is communicated. It was found that the reference architecture provides constructional principles in the engineering of IKNs, thus enabling the design, operation and research of this class of collaborative networks. The study therefore takes a first step toward extending the concept of EE to IKNs, and collaborative networks in general. This enables the greater adaptability of these networks to the dynamic environment of the Information Age. / AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek die ontwikkeling van geïntegreerde kennisnetwerke (GK’s) aan die hand van ‘n verwysingsargitektuur. Die doel van die studie is om ’n beter begrip van die onderliggende ontwerpbeginsels van hierdie klas kollaborasie netwerke te kry. Alhoewel beide GK’s en ondernemingsingenieurswese beskou word as belowende benaderings tot die uitdagings van die Inligtingsera, bestaan beduidende uitdagings steeds in die ontwikkeling van GK’s. Ons geglobaliseerde, gekommersialiseerde samelewing word tans gekenmerk deur beide buitengewone kompleksiteit en buitengewone tempo-verandering. Ondernemingsingenieurswese word beskou as ’n belowende benadering om ondernemings toe te rus met die eienskappe wat in aanvraag is in die moderne ekonomie, insluitend aanpasbaarheid en vlugheid. Ondernemingsargitektuur dra by tot hierdie poging deur ’n hoëvlak ontwerp van die onderneming te voorsien wat geïntegreerde ontwikkeling van die onderneming toelaat. Vanuit ’n kommersiële oogpunt word dit ruim aanvaar dat die vermoë om te innoveer en nuwe kennis te ontwikkel deur die ontwikkeling van nuwe produkte, dienste en prosesse ’n kernfaktor in die oorlewing van ondernemings is. Die jongste benadering in innovasiebestuur toon aan dat die innovasieproses nie meer slegs in een onderneming uitgevoer word nie. Dit lei dan tot interorganisasie-innovasienetwerke. Die belangrikheid van kennis as ’n dinamiese instaatsteller van hierdie netwerk-innovasiebenadering word verder beklemtoon. Dit het gelei tot die ontstaan van GK’s waarin kennis tot stand gebring en gedeel word tussen netwerk belanghebbendes om sodoende volhoubare innovasie te bevorder. Die toenemende tempo in verandering beteken dat ondernemings, insluitende GK’s, toenemend minder tyd het om op markveranderings en -geleenthede te reageer. Die klem val daarom op die ondernemingsingenieursweseen ondernemingsargitektuur-dissiplines as hulpmiddels om by die dinamiese landskap van die Inligtingsera aan te pas. Tans word die vermoë om omvattende ondernemingsingenieurswese in GK’s te beoefen, gekniehalter deur die tekort aan hulpbronne wat grondige konstruksie-beginsels vir hierdie netwerke beskryf. Die fokus van hierdie studie is daarom die toepassing van die ondernemingsingenieurswese-dissipline op GK’s deur die ontwikkeling van ’n verwysingsargitektuur. Die verwysingsargitektuur vir GK’s word ontwikkel deur ontwerpwetenskapnavorsing binne ’n pragmatiese en kwalitatiewe navorsingstrategie. Die navorsingsprobleem word eers geïdentifiseer en gemotiveer. Verskeie oplossingsdoelwitte word vervolgens bepaal. Hierna geskied die ontwerp en ontwikkeling van die verwysingsargitektuur deur middel van die vier herhalende ontwerpsiklusse. Die verwysingsargitektuur vir GK’s word gedemonstreer en geëvalueer deur ’n reeks beeldende scenario’s, waarna die bruikbaarheid, nuutheid en ontwerpstrengheid van die artefak gekommunikeer word. Dit is bevind dat die verwysingsargitektuur konstruksiebeginsels in die ontwikkeling van GK’s voorsien en sodoende die ontwerp, werk en navorsing in hierdie klas kollaborasie netwerke moontlik maak. Dié studie neem ‘n eerste tree in die rigting om die konsep van ondernemingsingenieurswese tot GK’s uit te brei. Dit maak die groter aanpasbaarheid van hierdie netwerke by die dinamiese omgewing van die Inligtingsera moontlik.

Organisations comprise human and technical systems that typically perform a variety of business, engineering and production roles. Human systems comprise individuals, people groups and teams that work systematically to conceive, implement, develop and manage the purposes of any enterprise in response to customer requirements. Recently attention has been paid to modelling aspects of people working within production systems, with a view to improving: production performance, effective resource allocation and optimum resource management. In the research reported, graphical and computer executable models of people have been conceived and used in support of human systems engineering. The approach taken has been to systematically decompose and represent processes so that elemental production and management activities can be modelled as explicit descriptions of roles that human systems can occupy as role holders. First of all, a preliminary modelling method (MM1) was proposed for modelling human systems in support of engineering enterprise; then MM1 was implemented and tested in a case study company 1. Based on findings of this exploratory research study an improved modelling method (MM2) was conceived and instrumented. Here characterising customer related product dynamic impacts extended MM1 modelling concepts and methods and related work system changes. MM2 was then tested in case study company 2 to observe dynamic behaviours of selected system models derived from actual company knowledge and data. Case study 2 findings enabled MM2 to be further improved leading to MM3. MM3 improvements stem from the incorporation of so-called DPU (Dynamic Producer Unit) concepts, related to the modelling of human and technical resource system components . Case study 4 models a human system for targeted users i.e. production managers etc to facilitate analysis of human configuration and also cost modelling. Modelling approaches MM2, MM3 and also Case Study 4 add to knowledge about ways of facilitating quantitative analysis and comparison between different human system configurations. These new modelling methods allow resource system behaviours to be matched to specific, explicitly defined, process-oriented requirements drawn from manufacturing workplaces currently operating in general engineering, commercial furniture and white goods industry sectors.

Thesis (MScEng (Industrial Engineering))--Stellenbosch University, 2008. / This study intends to develop a decision support tool for new business development units in South African consultancies. These consultancies endeavour to out‐license their technology assets. The enterprise engineering model is examined and the rules and boundaries of the Cartesian space is used to derive further functionality (susceptibility, segmentation and competence) from the various enterprise life cycles as measures for business expansion of knowledge organisations. The reader is presented with an overview of knowledge organisations, more specifically consultancy enterprises and its unique challenges and business models. These firms develop technology for specific market applications to assist them in solving industry specific problems. These technologies are easily modularised and packaged and can be transferred as technology assets to licensees. The bulk of the dissertation deals with the process phases in externally leveraging technology assets, with a focus on the intelligence phase of this process. The industrial engineering approach provides a suitable mindset for understanding the complexity of global strategy problems. Proposed global strategies are based on combinations of geographic areas that become more desirable over time. Levels of aggregation are defined, and the global eco‐socio‐political and economical systems are further investigated. Approaches to global strategy management are investigated, and the PEST framework is used in its broadest sense to conduct an external environmental analysis. Franchising as a method of out‐licensing is proposed as a mode of entry into foreign markets. The development of a decision support tool is supported by the generic system model and more specifically principles from productivity management. Multiple criteria decision modelling is discussed and efficiency and effectiveness are used as the objective and subjective variables. The Brown‐Gibson model is used to calculate a weighted evaluation, and the countries of the world are ranked according to these outcomes. Finally, a sensitivity analysis is conducted on the weighted evaluations providing the reader with graphs indicating what the long and short term focus of consulting firms should be regarding their out‐licensing endeavours on a macro environmental level. In conclusion, this study expands the enterprise engineering model for knowledge organisations (specifically consultancy enterprises) using analytical decision making methods in determining global strategy with a focus on the external environmental analysis.

Thesis (MScEng)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: The environment within which most organisations operate is ever-changing. In such a dynamic environment the only way an organisation is able to not just survive but thrive is by continuously, effectively and efficiently transforming/re-engineering itself (Hammer & Champy, 2001). Luckily, many organisations have realised and accepted this fact. The problem, however, is that the majority of transformation initiatives, launched by organisations, are unsuccessful. In fact, according to (Blanchard K. , 2010), 70% of change initiatives fail. There can only be two possible reasons for the existence of this very serious problem. Organisations either implement the wrong kinds of change initiatives or they ineffectively manage and execute the transformation efforts that they initiate. To solve this problem, an organisation needs to make use of a structured and integrated enterprise engineering methodology that enables it to effectively manage and execute the right kind of change initiatives (Martin, 1995). In the literature that was reviewed, very few structured and integrated enterprise engineering methodologies were found to exist. The objective of this study was to bridge this research gap. In other words, the objective of this study was to develop a structured and integrated enterprise engineering methodology. Developing the enterprise engineering methodology was done by following a basic system engineering process consisting of the following four steps: requirements analysis, system design, system development and system validation. During the requirements analysis step the functional characteristics that the enterprise engineering methodology needed to possess were identified. The purpose of the system design step was to firstly identify the set of methods that the enterprise engineering methodology should consist of and secondly to determine how these methods fit together to form an integrated methodology. The purpose of the system development step was to describe each of the methods that the enterprise engineering methodology needed to consist of in terms of how it is utilised as well as who should be involved during its utilisation. Lastly, during the system validation step the enterprise engineering methodology was evaluated based on how well it satisfies its functional requirements. Expert interviews as well as a case study were used to do this. / AFRIKAANSE OPSOMMING: Die meerderheid organisasies, huidiglik in bestaan, wroeg met die konstante veranderinge wat plaasvind in die omgewing rondom hulle. In so ‘n dinamiese omgewing is ‘n organisasie se toekomstige winsgewendheid en groei hewiglik afhanklik van sy bevoegdheid om aaneenlopend en effektief veranderinge aan te bring (Hammer & Champy, 2001). Die probleem is dat 70% van transformasie-inisiatiewe wat geloots word nie die voordele wat van hulle verwag word suksesvol lewer nie (Blanchard K. , 2010). Hoekom gebeur dit? Hoekom is net 30% van transformasie-inisiatiewe wat geloots word suksesvol? Daar is net twee moontlike redes vir die bestaan van hierdie probleem. Organisasies loots óf die verkeerde tipe transformasie-inisiatiewe óf hulle bestuur hulle transformasie-inisiatiewe op ‘n oneffektiewe manier. Om te verseker dat ‘n organisasie nie in hierdie strik trap nie, moet dit gebruik maak van ‘n gestruktureerde en geїntegreerde besigheidstransformasie-metodologie wat die proses van verandering vergemaklik (Martin, 1995). In die literatuur wat tot dusver nagevors is, kon daar maar ‘n handjievol besigheidstransformasie-metodologiëe opgespoor word. Die doel van hierdie studie was om hierdie gaping in die literatuur te vul. Met ander woorde, die doel van hierdie studie was om ‘n gestruktureerde en geїntegreerde besigheidstransformasie-metodologie te ontwikkel. ‘n Stelselontwikkelingsproses is gevolg om hierdie metodologie te ontwikkel. Die vier stappe wat deel gevorm het van hierdie stelselontwikkelingsproses is die volgende: vereistebeskrywing, stelselontwerp, stelselontwikkeling en stelselvalidasie. Tydens die vereistebeskrywingstap van die proses is die funksionele eienskappe wat die besigheidstransformasie-metodologie moet besit geïdentifiseer. Die doel van die stelselontwerpstap was eerstens om die metodes waaruit die metodologie moet bestaan te identifiseer en tweedens om die wisselwerking tussen die metodes te bepaal. Die doel van die stelselontwikkelingstap was om elkeen van die metodes waaruit die metodologie moet bestaan te beskryf in terme van hoe dit toegepas word, asook wie betrokke behoort te wees tydens die gebruik daarvan. Tydens die stelselvalidasiestap is die metodologie geëvalueer in terme van hoe effektief dit die geïdentifiseerde funksionele behoeftes bevredig. Onderhoude met deskundiges asook ‘n gevallestudie is gebruik om dit te doen.

Given the increasing emphasis on multi-perspective modelling, the University of Pretoria’s Industrial Engineering Department requires a tool that enables horizontal transformation between DEMO (Design and Engineering Methodology for Organisations) models and other models. This tool needs to be available free-of-charge, up-to-date, and vertically consistent, and should enable horizontal transformation between DEMO models and other models such as the BPMN (Business Process Model and Notation) models. Using design science research, this dissertation develops a part of this tool by first identifying and evaluating currently available tools, then discovering how other authors have approached model consistency and transformation, and finally developing a tool in ADOxx that supports the modelling of DEMO’s construction model– more specifically, the organisation construction diagram (OCD) and transaction product table (TPT) and transformations from the OCD to BPMN collaboration diagrams. The new tool, called DMT (Demo Modelling Tool), is demonstrated by modelling two case studies within the tool, and then performing four transformations. It is evaluated by having postgraduate participants model the same case study and rate the tool using pre-established usability criteria. / Dissertation (MEng)--University of Pretoria, 2020. / Industrial and Systems Engineering / MEng / Unrestricted

The delivery of innovative IT solutions that support business strategy is an increasing, growing competitive aspect of organisations in the financial sector. Previous research has shown the need to follow an innovative or a more agile and flexible methodology when delivering IT solutions to save cost and enable the solutions to reach the consumer market as soon as possible. To apply agile/innovative methodologies across large organisations requires more alternative approaches than to implement them in small enterprises. The organisation used in the case study, implemented an enterprise engineering innovative lifecycle (EEILC). Limited research has been done concerning the challenges and strategies during implementation of an EEILC. The purpose of this study was to investigate the strategies to overcome the challenges when implementing an EEILC. The research was inductive qualitative following an in-depth case study approach. The researcher conducted a case study using documentation analysis, informal interviews, in-depth interviews and observations with multiple stakeholders who are experts in their fields of software design and development. An inductive grounded theory approach was followed using a case study within an organisation in the financial sector in South Africa. Results show there are seven core category challenges when implementing an innovation life cycle. Each of these core challenges has a core enterprise strategy to address the challenges occurring in the applicable domain. The core challenges are: (1) innovation process challenges (addressed by an agile product delivery innovation strategy) (2) invention challenges (addressed by an idea management strategy) (3) business model challenges (addressed by a client’s value proposition strategy), (4) commercialization challenges, which include implementation and operations challenges, (addressed by a product portfolio management strategy), (5) culture challenges (addressed by an innovation culture strategy) and (6) knowledge management challenges and strategy, and (7) innovation management related challenges and strategy An innovation management strategy will manage all these challenges. Most prominent is the innovation management strategy which has links to all other categories in other domains. The relationship between enterprise client value proposition strategy show that enterprise client value proposition serves as a coherent link between how the innovation life cycle is adopted or changed to address the enterprise client value chain. This is driven by demand management to align between business and IT regarding the business model and application portfolio alignment. Thereafter, the alignment between the demand for enterprise application capabilities and the business service portfolio is shown. This is supported by service-oriented architecture (SOA) services. The resource management has to make sure the right resources, competencies and skills are available to deliver the product portfolio. During innovation and life-cycle's execution, there is a lot of interaction between individuals and teams. Therefore, communication and culture play a vital role to create synergies by collaboration of work practice and living the values of the organization. Through grounded theory analysis, a practical theory was developed, to show how challenges that occur during implementation of an innovation life-cycle, based upon enterprise engineering principles, can be addressed by best by putting the right strategies in place. This theory contributes to the body of knowledge by providing data and analysis from practical insight into how an innovation life cycle can be implemented. The challenges thereof and the mitigating strategies make it work. This study also suggested the key re best practices for enterprise architecture driving such an implementation. The research is an area of interest for development or customizing an Innovation Life-cycle using an Enterprise Engineering Framework.

Manufacturing today has become a matter of the effective and efficient application of information technology and knowledge engineering. Manufacturing firms success depends to a great extent on information technology, which emphasizes the integration of the information systems used by a manufacturing enterprise. This integration is also called enterprise application integration (here the term application means information systems or software systems). The methodology for enterprise application integration, in particular enterprise application integration automation, has been studied for at least a decade; however, no satisfactory solution has been found. Enterprise application integration is becoming even more difficult due to the explosive growth of various information systems as a result of ever increasing competition in the software market. This thesis aims to provide a novel solution to enterprise application integration. The semantic data model concept that evolved in database technology is revisited and applied to enterprise application integration. This has led to two novel ideas developed in this thesis. First, an ontology of an enterprise with five levels (following the data abstraction: generalization/specialization) is proposed and represented using unified modeling language. Second, both the ontology for the enterprise functions and the ontology for the enterprise applications are modeled to allow automatic processing of information back and forth between these two domains. The approach with these novel ideas is called the enterprise semantic model approach. The thesis presents a detailed description of the enterprise semantic model approach, including the fundamental rationale behind the enterprise semantic model, the ontology of enterprises with levels, and a systematic way towards the construction of a particular enterprise semantic model for a company. A case study is provided to illustrate how the approach works and to show the high potential of solving the existing problems within enterprise application integration.

Enterprise modelling can facilitate the design, analysis, control and construction of contemporary enterprises which can compete in world-wide Product markets. This research involves a systematic study of enterprise modelling with a particular focus on resource modelling in support of the life cycle engineering of enterprise systems. This led to the specification and design of a framework for resource modelling. This framework was conceived to: classify resource types; identify the different functions that resource modelling can support, with respect to different life phases of enterprise systems; clarify the relationship between resource models and other modelling perspectives provide mechanisms which link resource models and other types of models; identify guidelines for the capture of information - on resources, leading to the establishment of a set of resource reference models. The author also designed and implemented a resource modelling tool which conforms to the principles laid down by the framework. This tool realises important aspects of the resource modeffing concepts so defined. Furthermore, two case studies have been carried out. One models a metal cutting environment, and the other is based on an electronics industry problem area. In this way, the feasibility of concepts embodied in the framework and the design of the resource modelling tool has been tested and evaluated. Following a literature survey and preliminary investigation, the CIMOSA enterprise modelling and integration methodology was adopted and extended within this research. Here the resource modelling tool was built by extending SEWOSA (System Engineering Workbench for Open System Architecture) and utilising the CIMBIOSYS (CINI-Building Integrated Open SYStems) integrating infrastructure. The main contributions of the research are that: a framework for resource modelling has been established; means and mechanisms have been proposed, implemented and tested which link and coordinate different modelling perspectives into an unified enterprise model; the mechanisms and resource models generated by this research support each Pfe phase of systems engineering projects and demonstrate benefits by increasing the degree to which the derivation process among models is automated.
