Abstract Products and services are critical for companies as they create the foundation for companies’ financial success. Twenty per cent of company products typically account for some eighty per cent of sales volume. Nevertheless, the product portfolio decisions — how to strategically renew company product offering — tend to involve emotions, pet products and who-shout-the-loudest mentality while facts, numbers, and quantitative analyses are missing. Profitability is currently measured and reported at a company level, and firms seem unable to measure product-level profitability in a constant way. Consequently, companies are unable to maintain and renew their product portfolio in a strategically or commercially balanced way. The main objective of this study is to provide a data-driven product portfolio management (PPM) concept, which recognises and visualises in real-time and based on facts which company products are concurrently strategic and profitable, and what is the share of them in the product portfolio. This dissertation is a qualitative study to understand the topical area by the means combining literature review, company interviews, observations, and company internal material, to take steps towards data-driven decision-making in PPM. This study indicates that company data assets need to be combined and governed company-widely to realise the full potential of company strategic assets — the DATA. Data must be governed separately from business IT technology and beyond it. Beyond data and technology, the data-driven company culture must be adopted first. The data-driven PPM concept connects key business processes, business IT systems and several concepts, such as productization, product lifecycle management and PPM. The managerial implications include, that the shared understanding of the company products is needed, and the commercial and technical product structures are created accordingly, as they form the backbone of the company business as the skeleton to gather all product-related business-critical information for product-level profitability analysis. Also, product classification for strategic, supportive and non-strategic is needed, since the strategic nature of the product can change during the entire product lifecycle, e.g. due to the technology obsolescence, disruptive innovations by competitors, or for any other reason. / Tiivistelmä Tuotteet ja palvelut ovat yrityksille kriittisiä, sillä ne luovat perustan yritysten taloudelliselle menestykselle. Kaksikymmentä prosenttia yrityksen tuotteista edustaa tyypillisesti noin kahdeksaakymmentä prosenttia myyntimääristä. Siitä huolimatta tuoteporfoliopäätöksiin — kuinka strategisesti uudistetaan yrityksen tuotetarjoomaa — liittyy tunteita, lemmikkituotteita ja kuka-huutaa-kovimmin -mentaliteettia faktojen, numeroiden ja kvantitatiivisten analyysien puuttuessa. Kannattavuutta mitataan ja raportoidaan tällä hetkellä yritystasolla, ja yritykset eivät näyttäisi pystyvän mittaamaan tuotetason kannattavuutta johdonmukaisesti. Tämä estää yrityksiä ylläpitämästä ja uudistamasta tuotevalikoimaansa strategisesti tai kaupallisesti tasapainoisella tavalla. Tämän tutkimuksen päätavoite on tarjota dataohjattu (data-driven) tuoteportfoliohallinnan konsepti, joka tunnistaa ja visualisoi reaaliajassa ja faktapohjaisesti, mitkä yrityksen tuotteet ovat samanaikaisesti strategisia ja kannattavia ja mikä on niiden osuus tuoteportfoliossa. Tämä väitöskirja on laadullinen tutkimus, jossa yhdistyy kirjallisuuskatsaus, yrityshaastattelut, havainnot ja yritysten sisäinen dokumentaatio, joiden pohjalta pyritään kohti dataohjautuvaa päätöksentekoa tuoteportfolion hallinnassa. Tämä tutkimus osoittaa, että yrityksen data assettit on yhdistettävä ja hallittava yrityksenlaajuisesti, jotta yrityksen strategisten assettien — DATAN — potentiaali voidaan hyödyntää kokonaisuudessaan. Data on hallittava erillään yrityksen IT-teknologiasta ja sen yläpuolella. Ennen dataa ja teknologiaa on omaksuttava dataohjattu yrityskulttuuri. Dataohjatun tuoteportfolionhallinnan konsepti yhdistää keskeiset liiketoimintaprosessit, liiketoiminnan IT-järjestelmät ja useita konsepteja, kuten tuotteistaminen, tuotteen elinkaaren hallinta ja tuoteportfolion hallinta. Yhteisymmärrys yrityksen tuotteista ja sekä kaupallisen että teknisen tuoterakenteet luominen vastaavasti on ennakkoedellytys dataohjatulle tuoteportfolion hallinnalle, koska ne muodostavat yrityksen liiketoiminnan selkärangan, joka yhdistää kaikki tuotteisiin liittyvät liiketoimintakriittiset tiedot tuotetason kannattavuuden analysoimiseksi. Lisäksi tarvitaan tuotteiden kategorisointi strategisiin, tukeviin ja ei-strategisiin tuotteisiin, koska tuotteen strateginen luonne voi muuttua tuotteen elinkaaren aikana, johtuen esimerkiksi teknologian vanhenemisesta, kilpailijoiden häiritsevistä innovaatioista tai mistä tahansa muusta syystä.

The purpose of this paper was to investigate the integration between Life Cycle Assessment (LCA) and Computer-Aided Design (CAD). The project has been carried out as a degree project at Karlstad University in the spring of 2023 on behalf of the company TECHNIA. The project was a master's thesis of 22.5 higher education credits for the higher education engineering program in Innovation Technology and Design. The project has been structured to achieve the purpose and goals of the assignment. The work consisted of investigating the capacity and user-friendliness of an integrated LCA and CAD system by using literature as support and investigating and analysing the system and performing case studies. To achieve the purpose and goal, Dassault Systèmes 3DEXPERIENCE has been used as support. The issue of sustainability today has great weight, and companies increasingly choose sustainable solutions, which is partly due to pressure from external stakeholders. This project highlights the most important trends in sustainability. It is an attractive factor on the market which is relevant for all types of industries. Surveys have also been carried out to map facts about the LCA and CAD integration. Through theoretical investigations, a comprehensive understanding of the integration between LCA and CAD as well as its importance for sustainable development has been highlighted. The case studies carried out were conducted as interviews at two companies, EDAG and Mölnlycke Health Care, where the interviews were crucial in creating an approach to the use of an integrated system. Use of the integrated system then contributed to a deeper understanding of the functions. By combining the methods used, the project was able to meet its goals. The methods generated results describing advantages, disadvantages, practices, tools, and approaches when using integrated LCA and CAD. The conclusion is that an integration between LCA and CAD has many advantages compared to a traditional LCA tool. An integrated system is more efficient and easier to use. / Uppsatsens ändamål var att undersöka integrationen mellan livscykelanalys (LCA) och datorstödd design (CAD). Projektet har genomförts som ett examensarbete vid Karlstads Universitet under våren 2023 på uppdrag av företaget TECHNIA. Projektet som genomfördes var en kandidatuppsats om 22,5 högskolepoäng för programmet högskoleingenjörsprogrammet i Innovationsteknik och Design. Projektet har varit uppbyggt för att uppnå syftet samt målen för uppdraget. Kortfattat gick arbetet ut på att undersöka kapaciteten och användarvänligheten med ett integrerat LCA och CAD system genom att använda litteratur som stöd, undersöka och analysera systemet samt att utföra fallstudier. För att uppnå syftet och målet har Dassault Systèmes 3DEXPERIENCE användes som stöd. Hållbarhetsfrågan i dagens samhälle har stor vikt och företag väljer alltmer hållbara lösningar, som delvis beror på press från externa intressenter. Projektet belyser de viktigaste trenderna inom hållbarhet och att det är en attraktiv faktor på marknaden som är relevant för alla typer av industrier. Undersökningar har också genomförts för att kartlägga fakta om LCA och CAD integrationen. Genom teoretiska undersökningar har omfattande förståelse av integrationen mellan LCA och CAD samt dess betydelse för hållbar utveckling belysts i examensarbetet. Fallstudierna som utfördes gjordes som intervjuer på två företag, EDAG och Mölnlycke Health Care, där intervjuerna var avgörande för att skapa ett tillvägagångssätt för användning av systemet. Användning av det integrerade systemet bidrog sedan till en djupare förståelse för funktionerna. Genom att kombinera de använda metoderna kunde projektet uppfylla sina mål. Metoderna genererade resultat som beskriver fördelar, nackdelar, praxis, verktyg samt tillvägagångssätt vid användning av integrerad LCA och CAD. Slutsatsen är att ett integration mellan LCA och CAD har många fördelar i jämförelse med ett traditionellt LCA-verktyg. Ett integrerat system är mer effektivt och enklare att använda.

Ces travaux portent sur la conception multidisciplinaire de systèmes intégrés. Ces systèmes sont soumis à un nombre d’exigences toujours croissant, entraînant des besoins en termes d’intégration fonctionnelle et spatiale. Ces différents types d’intégration relative au produit sont également la source d’une complexité organisationnelle, provenant à la fois de la multitude d’acteurs réalisant différentes activités d’ingénierie, mais également de la diversité des domaines impliqués, désignée dans ce manuscrit par « intégration multidisciplinaire ». Pour favoriser cette intégration multidisciplinaire, les phases de « conception préliminaire » et de « conception détaillée » ont été identifiées comme déterminantes, notamment car elles se caractérisent par la collaboration de nombreux experts, manipulant un grand nombre de données techniques de définition. Les systèmes conçus lors de conceptions multidisciplinaires restent faiblement intégrés. Cela est en partie dû au cloisonnement entre les disciplines et à un mode d’organisation projet basé sur une planification prédominante, caractérisé notamment par une diffusion de l’information principalement descendante (top-down). Afin d’assurer une meilleure collaboration entre ces différentes disciplines, de permettre des prises de décision éclairées par des indicateurs opérationnels et de pouvoir analyser et mieux comprendre les phénomènes d’intégration des expertises, l’introduction d’une méthode inspirée des principes fondateurs des méthodes agiles est proposée pour la conception collaborative de systèmes intégrés.La contribution de ces travaux s’appuie sur trois concepts complémentaires. Le premier, intitulé Collaborative Actions Framework correspond à un cadre de collaboration opérationnelle autour d’actions. Un des objectifs de ce framework est de faciliter la collaboration des acteurs des projets de conception, quelle que soit leur origine disciplinaire, mais également d’assurer une traçabilité entre les prises de décision et les corrections/modifications apportées sur les données techniques. Cette traçabilité est rendue possible grâce aux liens existants avec le second concept intitulé Workspace. Apportant un nouvel éclairage sur les possibilités offertes par la collaboration autour de ces espaces de collaboration, ce concept offre un certain nombre de possibilités,notamment la mise en commun continue des travaux, l’intégration multidisciplinaire et la validation des modifications. Les échanges de données techniques entre les workspaces, ou le travail simultané sur les mêmes données techniques, s’appuient quant à eux sur la possibilité de pouvoir gérer de façon parallèle différentes versions d’une même donnée technique. Ces possibilités sont proposées par le troisième concept, intitulé branch & merge, qui permet également à différents acteurs de travailler simultanément sur les mêmes données. Enfin, ces trois concepts sont ensuite illustrés par l’intermédiaire d’un démonstrateur composé d’un scénario et d’un prototype informatique. Un produit mécatronique, combinaison synergique et systémique de la mécanique, de l'électronique et de l'informatique temps réel, est utilisé afin d’illustrer les possibilités offertes par nos travaux en termes d'intégration multidisciplinaire lors de la conception collaborative. / This work focuses on the multidisciplinary and collaborative design of integrated systems. These systems are subject to an ever increasing number of requirements, leading to the need for more comprehensive functional and spatial integration. These different types of product integration are also at the origin of organizational complexity. This complexity arises not only from the great number of actors performing various engineering activities but also from the diversity of disciplines involved (designated in this manuscript as “multidisciplinary integration”). To encourage this multidisciplinary integration, “preliminary design” and “detailed design” have been identified as the most significant steps, especially since they are characterized by the collaboration of multiple experts handling a large number of product definition’ technical data. Systems that have been designed thanks to multidisciplinary approaches are generally poorly integrated. This is partially due to the compartmentalization of disciplines, as well as to the “project-planned” method, where project planning is predominant and information is mainly spread out “top-down”. To ensure better cooperation between the various disciplines, to enable decision making based on operational indicators and to analyze and understand the multidisciplinary integration processes, a method inspired by the founding principles of agile methods (the agile manifesto) is proposed for the collaborative design of integrated systems. This work is based on three complementary concepts. The first is, the Collaborative Actions Framework, an operational framework for collaboration around actions. One objective of this framework is to improve the collaboration among designers, whatever their disciplinary origin. It also ensures traceability between decision making and corrections/changes made to technical data. This traceability is made possible by the useof the second concept, called Workspace. Even if this term is already well known, we propose a new definition/usage to transform it into collaboration spaces. This concept offers great possibilities, including the continuous delivering/sharing of experts’ contributions, multidisciplinary integration and change validation. The exchange of technical data between workspaces, or simultaneous work on the same data, relies on the ability to manage several parallel versions of the same item into a single datamanagement system. These opportunities are offered by the third concept, called Branch & Merge. Finally, these three concepts are illustrated through a scenario and a computer prototype. A mechatronic product, “the synergistic combination of mechanical and electrical engineering, computer science, and information technology” (Harashima et al., 1996), is used to illustrate the opportunities offered by our work in terms of multidisciplinary integration during collaborative design.

The thesis includes diagnostics temperature field of industrial low voltage. Place of origin, flow and heat transfer are important aspects in the design of the switchgear, especially in terms of proper equipment layout. The correctness of the design of the switchgear is verified by measuring the practical temperature field during testing or in work mode. To determine the temperature profile, it is necessary to measure the temperature at various points of the switchgear, either contact or contactless method. Measurements are performed on standardized low voltage switchboards, which are located power elements. The goal is to replace costly and time-consuming field testing switchgear efficient simulation of the temperature field mathematical model developed switchboards.

<p>  The world continues to advance at a hastening pace towards a technology enabled, digital-centric future. Legacy organizations, not born in the ‘digital age’ are examining methods to adapt through Digital Transformation (DT). The US Department of Defense (DoD) is one such organization. The DoD emerged their 2018 Digital Engineering Strategy intending on transforming the enterprise from one with ‘engineering process [that] are document-intensive and stove-piped, leading to extended cycle times with systems that are cumbersome to change and sustain’ to one that is ‘transforming its engineering practices to digital engineering, incorporating technological innovations into an integrated, digital, model-based approach’. </p> <p>  The 2018 Strategy acknowledges that the integration of digital engineering will not be exclusive to the engineering communities of the DoD; rather, the integration will impact the ‘research, requirements, acquisition, test, cost, sustainment and intelligence communities’. While the Strategy is designed to explain the ‘what’ necessary to integrate digital engineering, the various DoD Services (and their subordinates) will need to develop the ‘how’ regarding implementation that is culturally appropriate to their commands.</p> <p>  The study sought to examine ‘how’ implementation of digital engineering tenets may be appropriated to the existent culture of one US Special Operations Command subordinate at the Echelon III level (namely Naval Special Warfare Group – FOUR). The results of this study are intended to provide understanding and illuminate meaning behind those themes in Digital Engineering that Subject Matter Experts within Naval Special Warfare view as suitably adaptable to their processes. The intent is to provide themes with utility towards further efforts and research aimed at phasing Digital Transformation initiatives at Naval Special Warfare Group – FOUR.</p>

由微笑曲線理論(施振榮1992年提出)知道企業應該朝高附加價值領域發展，而其中上游智財權(Intelligent Property)、知識經濟(Knowledge Economics)是我國OEM、ODM製造業將生產基地移到大陸後，為避免國內產業空洞化，必須在國內深耕的核心競爭力領域。要強化智財權、知識經濟則必須強化產品研發與創新能力，而產品研發與創新能力的提升必須藉助良好的「協同產品研發生命週期管理解決方案」(Collaborative product development lifecycle management solution) ；但是此解決方案尚在發展初期，不論企業或是個人對於它皆了解不夠，也不知如何利用此解決方案來提升產品研發能力。 因此本研究透過文獻的收集與探討，整理出PLM(Product Lifecycle Management)解決方案的定義、演進，並對PLM解決方案的架構進行探討，再針對市場上PLM解決方案系統廠商所提供的PLM系統產品進行說明，讓有意導入PLM解決方案的公司企業可以參考。另外由於知識管理可以讓PLM系統所收集的產品資料與產品研發經驗與知識得以分享、流通與再創造與加值，因此對於知識管理(Knowledge Management)與PLM的關係進行探討。2003年歐盟立法通過兩大環保法規—WEEE(Waste Electronics and Electrical Equipment)及RoHS(Restriction of Hazardous Substances)，要求製造廠商從設計開始即需考慮整個產品生命週期的環境保護觀念，此法規讓產品生命週期觀念有了具體的落實實施，因此本研究亦對綠色環保法規與PLM解決方案的關係進行探討與說明。 本研究為協助企業在導入PLM解決方案前，能夠深入了解PLM解決方案，因此以個案研究方式深入分析個案公司在協同研發產品生命週期中所面臨的問題，並針對這些問題提出PLM系統解決方案的建構策略，也提出PLM系統整合應用架構做為PLM企業策略方法施行的基礎；此PLM系統整合應用架構的特色包括以產品為核心，重視人員、流程及產品資訊；涵蓋從產品觀念的構思開始一直到產品生命結束為止的全生命期間的管理與支援；支援涵蓋跨部門、客戶、設計夥伴與供應夥伴等跨企業間的協同合作。並說明此整合應用架構在協同產品研發生命週期管理中的運作情境，最後再對導入PLM系統解決方案提出規劃重點與想法。 本研究在研究過程中有底下幾點重要發現，特別整理如下： 一、 因為綠色環保法規的規定而使得產品生命週期觀念能落實執行。 二、 PLM是一種企業策略方法，要成功導入必須從人員、流程、資訊科技三方面同時規劃。 三、 由於PLM系統架構的定義不同，且PLM系統廠商所提供的PLM系統解決方案亦有不同功能，企業必須根據自己的需求選擇適當的解決方案。 四、 PLM理念一直不斷變化與延伸，PLM系統已成為製造業不可或缺的系統。 對於後續研究者，本研究建議的未來研究方向如下： 一、 建議對於導入PLM要如何進行變革管理進行研究。 二、 建議對於如何利用知識管理來協助研發創新進行研究。 三、 建議對於PLM解決方案所帶來的協同產品研發績效的影響進行研究。 / Referring to the Smiling Curve Theory (Shih Chen-Rong, 1992), it is realized that enterprise should gradually lead the “High Value-Added” concept to its management system. Since recent years, Taiwan local OEM and ODM factories widely moved their production base to Mainland China, and so in order to avoid domestic industries being emptied, “Intelligent Property” and “Knowledge Economics” must be cultivated deep into our country. On the other hand, prior to strengthen Intelligent Property and Knowledge Economics, the premise is to strengthen the competency of Product Development and Product Innovation. In addition, to enhance the competency of Product Development and Product Innovation must follow by good “Collaborative product development lifecycle management solution”. However, the solution is still at initiation phase, therefore so far as now, either the enterprises or the individuals are not acquainted with it, and also do not know well how to utilize the solution to reinforce the Product Development competency. By means of the concept mentioned above, literatures are collected and investigated by this study to work up the definition and evolution of PLM (Product Lifecycle Management) Solution. In advance, the framework of PLM solution is discussed; and the PLM system, provided by supplier, is introduced by this research as well, in order to allow businessmen, who would like to lead PLM Solution into their organizations, to adopt them as a reference for developing their enterprises. Moreover, considering of that Knowledge Management enables the experience and knowledge of Product Development and Product Information, collected by PLM system, to be shared, circulated, recreated and value-added, the relation between Knowledge Management and PLM system is examined in this study. Also, the relation between the legislated rules of Green Environmental Protection and PLM Solution is researched and reported in response to the two regulations of WEEE (Waste Electronics and Electrical Equipment) and RoHS (Restriction of Hazardous Substances), which were legislated by European Union (EU) in 2003. In accordance with the two statutes, manufacturers are requested to think of the concept of environmental protection for the entire Product Lifecycle, starting from product design begins. For the sake of assisting enterprises in understanding deeply about the PLM Solution, before introducing it into their organization, “case study” access is therefore adopted by the study to analyze in deep the problems on “Collaborative product development lifecycle management solution”, which might be incurred in each individual case. In line with the problems, a constructional strategy for PLM system as well as a framework of the application and integration of PLM system are proposed as a base of executing business strategic approach. Characteristics of the framework of the application and integration of PLM system include “strategic core by product”; “to value personnel, operation flow and product information”; “to manage and support the entire lifecycle from product concept to product lifespan being ended”; “the support covers collaboration between the divisions, customers, designing coworkers, suppliers. In addition, the running situation of this framework, which runs under the “Collaborative product development lifecycle management solution” is presented in the study. In the final part of the research, the key-points and strategies are presented for the proposal of introducing PLM systemic solution. During the researching process, some important conceptions are discovered, and are summarized as follow: 1. Owing to the rules of Green Environmental Protection is legislated, it therefore enables the concept of product lifecycle be executed accurately. 2. PLM is a business strategic approach, so to introduce into enterprise successfully must through a proposal with the factors of personnel, operation flow and information technology simultaneously. 3. Since PLM system has varied system as well as different solution function from different suppliers, enterprises should choose a proper PLM systemic solution based on actual needs. 4. PLM concept varies and extends consecutively, so today PLM has become to the only system for option. Hereunder suggestions from researcher to the latter in future as the researching direction reference. 1. Suggest proceeding study with how to run Reformation Management after the adoption of PLM system. 2. Suggest proceeding study with how to utilize Knowledge Management for assisting in developing innovation. 3. Suggest proceeding study with the subject of “Influence on the results of collaborative product development by PLM systemic solution”.

Von Beginn der flexiblen Automatisierung mit numerisch gesteuerten Werkzeugmaschinen und der zugehörigen Programmier-Software bis zum gegenwärtigen Entwicklungsstand (Industrie 4.0) wird die historische Entwicklung von 1960 bis 2020 aus der Position eines aktiven Mitgestalters dargestellt. Interessanterweise vollzogen sich die wesentlichen Entwicklungsetappen für die ersten dreißig Jahre parallel in beiden deutschen Staaten. Aus den Lehren des Zweiten Weltkrieges wurden im Rahmen der UNESCO zum friedlichen Informationsaustausch geeignete wissenschaftliche Organisationen gegründet: • IFIP (Internationale Föderation für Informationsprozesse, speziell Arbeitsgrupp CAM • CIRP (Internationale Akademie der Fertigungstechniker) Mit der Berufung und aktiven Mitarbeit in diesen Organisationen war eine Plattform für die deutsch-deutsche und darüber hinaus internationale Kooperation gegeben. Ein besonderer Schwerpunkt für den geordneten Informationsaustausch im Rahmen der gesamten dynamischen Entwicklung im Gebiet der Produktionsautomatisierung war dabei die im 3-Jahres-Rhythmus durchgeführte Konferenzserie PROLAMAT (Programming Languages for Machine Tools), gestartet 1969 in Rom. Im weiteren Verlauf wurde dieser Begriff viel breiter für das gesamte Gebiet der automatisierten Informationsverarbeitung und Fertigung erweitert. Ein besonderer Höhepunkt war dabei die erfolgreichste PROLAMAT-Konferenz 1988 in Dresden. Parallel dazu erfolgten an der TU Dresden Entwicklungen in Richtung CAD/CAM-Labor und später CIM-TT (CIM-Technologietransferzentrum). Damit war an der TU Dresden 1989/90 ein Entwicklungsstand gegeben, der unmittelbar zu gemeinsamen deutsch-deutschen und internationalen EU-Projekten genutzt werden konnte. Dieses hohe Entwicklungsniveau wurde zur offiziellen Eröffnung des CIM-TT-Zentrums in den Eröffnungsreferaten durch den damaligen Wissenschaftsminister Dr. Riesenhuber und Ministerpräsident Prof. Biedenkopf gewürdigt. Durch die zum gleichen Zeitpunkt verfügte veränderte Nutzung des für das CIM-TT im Aufbau befindliche Gebäude durch die neugegründete Juristische Fakultät wurde der erfolgreich vorbereitete Weg verhindert. Unabhängig davon blieb meine fachliche Orientierung mit den gravierenden Weiterentwicklungen eng verbunden. Dazu trug das Sabbatical-Jahr in Norwegen und den USA 1992 maßgeblich bei. Mit dem Forschungsaufenthalt war die Entscheidungsvorbereitung für die vorgesehene Groß-Investition für das neueste generative Verfahren verbunden. Gleichzeitig mit dem fundierten Nachweis der bestgeeigneten sog. Rapid-Prototyping-Anlage vom deutschen Anbieter EOS München war die TU Dresden auf diesem neuen High-Tech-Gebiet 1992 in einer anerkannten Spitzenposition. Mit meiner Publikation eines der ersten Fachbücher im Gebiet Advanced Prototyping (jetzt Additiv Manufacturing) war darüber hinaus eine gute Basis für weitere innovative Aktivitäten gegeben Dazu gehört die Gründung einer High-Tech-Firma (SFM - Schnelle Fertigung von Modellen) mit bemerkenswerten beispielgebenden Ergebnissen. Hervorgehoben soll die zwanzigjährige aktive Kooperation mit der Universität Stellenbosch (RSA - Republik Südafrika), die unter anderem mit meiner Berufung zum Extraordinary Professor im Jahr 2003 verbunden ist. Mit der Eröffnung eines Technologie-Zentrums nach dem Vorbild des ursprünglichen CIM TT -Zentrums der TU Dresden konnte für Südafrika ein wertvoller Beitrag geleistet werden. Das gesamte Lebenswerk ist gekennzeichnet durch die Entwicklungsschritte von der Mathematisierung über die Algorithmierung bis hin zur Programmierung vielfältiger technologischer Sachverhalte. Die Ergebnisse sind in einer Anzahl von persönlichen Fachbüchern (z.T. übersetzt in das Russische und Ungarische) wie auch Konferenzberichten und mehr als 200 Veröffentlichungen (deutsch und englisch) dokumentiert.
