Leveraging IoT Protocols : Integrating Palletization Algorithm with Flexible Robotic Platform

Ferm Dubois, Mathias January 2024 (has links)
This thesis explores the integration of IoT protocols to enhance supply chain efficiency and sustainability by developing a flexible automated system. The research covers the integration of a palletization optimizer with a flexible robotic platform, a project conducted in collaboration with OpiFlex and Linköping University. Flexibility and sustainability in production, particularly in the food and beverage industry, are critical yet challenging to achieve. This research addresses these challenges by proposing a system that aligns the output with customer needs by combining these technologies. The research employs a combination of case study and exploratory methodologies. The development approach synthesizes elements from Set-Based Design, Point-Based Design, and Agile development frameworks. The primary research questions focus on identifying the best system architecture for integrating the palletization optimizer with a lower-level automation platform and outlining the steps needed to transform this integration into a commercially viable product. The system includes the optimizer, capable of processing customer orders and configuring products on mixed output pallets, integrated with a flexible robotic system provided by OpiFlex. The work involved evaluating communication protocols, MQTT, OPC UA, and TCP/IP, and designing robust interactions and interfaces between the subsystems. The results demonstrate the system's architecture and interaction protocols.  The thesis concludes with a discussion of the results in comparison to the application scenario and the standards consulted. The conclusion is that the chosen interface practices should remain largely intact but be re-developed using an OPC UA-based architecture. The main reasons for this are its support for both pub/sub and client-server models, increased security, and greater support for enterprise application integration. However, depending on the specific application, the downsides of OPC UA may outweigh its benefits.

Élites dirigeantes, sortie de crise et reconstruction post-conflit dans les États africains de la Région des Grands Lacs.1990-2013 / Governing Elites, end of crisis and post-conflict reconstruction in the African States of the Great Lakes Region

Demba, Guy-Eugène 31 January 2014 (has links)
Depuis plus de deux décennies, un nombre d’Etats africains dits du champ de la Conférence Internationale sur la Région des Grands Lacs sont enlisés dans des conflits armés à la fois intra-étatiques et internationalisés. Du génocide rwandais aux guerres civiles au Congo-Brazzaville, en Angola, en Ouganda, au Burundi, ou encore aux violences politiques armées incessantes en Centrafrique, en passant par la Grande Guerre Africaine en RDC, nombreux et importants sont les mécanismes de résolution de conflits qui ont été expérimentés, de nature aussi bien bilatérale, communautaire, régionale, qu’onusienne. Malheureusement, les concepts de sortie de crise et de reconstruction post-conflit demeurent de vains mots, eu égard aux résurgences et aux prolongements des conflits dans cette Région. Ainsi, en mobilisant l’approche néo-élitiste s’inscrivant dans un dépassement de la réalité empirique, après avoir passé en revue toutes les grandes théories philosophico-politico-sociologiques des élites, défendues par les auteurs classiques comme Wilfredo Pareto, Gaetano Mosca etc., d’un côté, et en recourant à la théorie de Johan Galtung de paix négative versus paix positive, d’autre part, cette étude se propose de mettre en évidence le rôle des élites dirigeantes dans la dynamique de pacification de la Région. Et après avoir défini et déterminé celles-ci, le travail démontre la difficulté de résoudre les conflits due à l’hétérogénéité sociologique caractérisant la Région. Puis, il souligne les mécanismes de l’entretien d’une paix négative par les élites dirigeantes, en interaction avec les autres protagonistes. / For more than two decades, a number of African States within the scope of the International Conference on the Great Lakes Region have sunk into both armed intrastate and domestic conflicts. From the Rwandan genocide to civil wars in Congo-Brazzaville, Angola, Uganda, and Burundi, or the constantly armed political violence in the Central African Republic (CAR), through the Great African War in the Democratic Republic of Congo (DRC), numerous and important mechanisms for conflict resolution have been experienced, bilateral, communitarian, regional, as well as Onusian. Unfortunately, the concepts relative to the end of crisis and post-conflict reconstruction still remain empty words, given the revivals and extensions of conflicts in that Region. Thus, by mobilizing the neo-elitist approach which goes the empirical reality, after reviewing all the major elitist philosophical, political and sociological theories defended by the classical authors such as Wilfredo Pareto, Gaetano Mosca, etc. On one hand, and by resorting to Johan Galtung’s theory on negative peace versus positive peace, on the other, this dissertation aims at highlighting the role played by governing Elites in the peace process within the Region. After defining these elites, this monography shows the difficulties of solving conflicts due to the regional sociodemographic heterogeneity. Then, it emphasizes mechanisms for keeping negative peace by the governing Elites, in interaction with other protagonists.
