La thèse porte sur le contrôle des systèmes de systèmes (SdS) et, sur la manière de construire des SdS adaptables et fiables. Ce travail fait partie du laboratoire d’excellence Labex MS2T sur le développement des SdS technologiques. Les SdS sont des systèmes complexes constitués de plusieurs systèmes indépendants qui fonctionnent ensemble pour atteindre un objectif commun. L’ingénierie des SdS est une approche qui se concentre sur la manière de construire et de concevoir des SdS fiables capables de s’adapter à l’environnement dynamique dans lequel ils évoluent. Compte tenu de l’importance du contrôle des systèmes constituants (SC) pour atteindre les objectifs du SdS , la première partie de cette thèse a consisté en une étude bibliographique sur le sujet du contrôle des SdS. Certaines méthodes de contrôle existent pour les systèmes à grande échelle et les systèmes multi-agents, à savoir, le contrôle hiérarchique, distribué et décentralisé peuvent être utiles et sont utilisés pour contrôler les SdS. Ces méthodes ne conviennent pas pour contrôler un SdS dans sa globalité et son évolution, en raison de l’indépendance de leur SC ; alors que les “frameworks” multi-vues conviennent mieux à cet objectif. Une approche de ”framework” générale est proposée pour modéliser et gérer les interactions entre les SC dans un SdS. La deuxième partie de notre travail a consisté à contribuer aux systèmes de transport intelligent. À cette fin, nous avons proposé le gestionnaire de manœuvres coopératives pour les véhicules autonomes (CMMAV), un “framework” qui guide le développement des applications coopératives dans les véhicules autonomes. Pour valider le CMMAV, nous avons développé le gestionnaire de manœuvres latérales coopératives (CLMM), une application sur les véhicules autonomes qui permet d’échanger des demandes afin de coopérer lors de manœuvres de dépassement sur autoroute. Cette application a été validée par des scénarios formels, des simulations informatiques, et testée sur les véhicules autonomes du projet Robotex au laboratoire Heudiasyc. / This thesis focuses on System of Systems (SoS) control, and how to build adaptable and reliable SoS. This work is part of the Labex MS2T laboratory of excellence on technological SoS development. SoS are complex systems that consist of multiple independent systems that work together to achieve a common goal. SoS Engineering is an approach that focuses on how to build and design reliable SoS that can adapt to the dynamic environment in which they operate. Given the importance of controlling constituent systems (CS) in order to achieve SoS objectives, the first part of this thesis involved a literature study about the subject of SoS control. Some control methods exist for large-scale systems and multi-agent systems, namely, hierarchical, distributed, and decentralized control might be useful and are used to control SoS. These methods are not suitable for controlling SoS in its whole, because of the independence of their CS; whereas, multi-views frameworks are more suitable for this objective. A general framework approach is proposed to model and manage the interactions between CS in a SoS. The second part of our work consisted of contributing to Intelligent Transportation Systems. For this purpose, we have proposed the Cooperative Maneuvers Manager for Autonomous Vehicles (CMMAV), a framework that guides the development of cooperative applications in autonomous vehicles. To validate the CMMAV, we have developed the Cooperative Lateral Maneuvers Manager (CLMM), an application on the autonomous vehicles that enables equipped vehicles to exchange requests in order to cooperate during overtaking maneuvers on highways. It was validated by formal scenarios, computer simulations, and tested on the autonomous vehicles of the Equipex Robotex in Heudiasyc laboratory.

Business architecture is compared to the enterprise architecture discipline still unexplored. While a number of papers and literature on enterprise architecture has been written, business architecture remains behind in this respect. This thesis mainly deals with the creation of a conceptual model of business architecture artifacts and comparing them with open source tools. The primary objective of this study is to compare open source tools to support the business architecture artifacts. To fulfill this primary objective is important secondary objective. The secondary objective is to analyze the most highly cited expert articles and scientific literature and analyzing the most common architectural frameworks in organizations. Based on the analysis of these sources of information create conceptual artifacts BA model with the largest number of their occurrence. These artifacts will be assigned to specific models, which fulfill them. After reaching the secondary target, comes the fulfillment of the primary objectives. Then selected open source tools will be compared with that created a conceptual model and evaluated as a measure of its fulfillment.

Technology is accepted as one of the key aspects that influence society and business in an unmistakable manner. Current literature is however not singular in its views and methods of technology strategy, its interface with business strategy, and how technology strategy is executed and assessed internally. The text adopts a 3-tiered domain approach at the outset, focusing on the integration of (i) strategy, (ii) measurement and (iii) architecture. The literature assessment was carried out on the hand of the three domains and ultimately resulted in the proposed internal technology strategy assessment framework for the services sector. At the heart of the framework is the merging of the disciplines and current models of (i) technology management (MOT), (ii) business architecture, (iii) strategic performance measurement and (iv) total quality management. The model aims to indicate that specific modelling techniques coupled with an excellence scorecard, can facilitate the mathematical assessment of strategic contribution of individual technology artefacts to a specific business strategy. The proposed model is represented in the text in flowchart form and is supplemented by the derivation of the required research approach, namely case study protocol. Three case studies were conducted, each of which is resident in the services sector, and the tabulated results are presented in the text and its appendixes. The results obtained indicate that strategic artefact differentiation on a procedural level can indeed be obtained. These results are consistent throughout the three case studies and valuable future benefit could be extrapolated for (i) continuing investigation on the hand of the model, as well as (ii) cross-pollination to the disciplines of (a) enterprise modelling and design and (b) project management. / Dissertation (MEng (Technology Management))--University of Pretoria, 2006. / Graduate School of Technology Management (GSTM) / unrestricted
