Design of Complex Engineered Systems Using Multiagent Coordination

This thesis is the combination of two research publications working toward a unified strategy in which the design of complex engineered systems can be completed using a multiagent coordination approach. Current engineered system modeling techniques segment large complex models into multiple groups to be simulated independently. These methods restrict the evaluations of such complex systems, as their failure properties are typically unknown until they are experienced in operation. In an effort to help engineers to design complex engineered systems, this research proposes that a distributed yet non-legislated approach can be used in the design processes by splitting up the overall system into specific teams. The approach specifically hypothesizes that multiagent credit assignment can be used to effectively determine how to properly incentivize subsystem designers so that the global set of system-level objectives can be achieved. The first publication presents a multiagent systems based approach for designing a self-replicating robotic manufacturing factory in space. The simulation in this work is able to present the coordination of the agents during the construction of the factory as the parameters of the learning algorithm are changed. The results show the advantage of using a learning algorithm to design a large system. The second publication presents a hybrid approach to design complex engineered systems, providing a method in which design decisions can be reconciled without the need for either detailed interaction models or external legislating mechanisms. The results of this paper demonstrate that a team of autonomous agents using a cooperative coevolutionary algorithm can effectively design a complex engineered system. Each publication utilized a system model to illustrate and simulate the methods and potential results. By designing complex systems with a multiagent coordination approach, a design methodology can be developed in an effort to reduce design uncertainty and provide mechanisms through which the system level impact of decisions can be estimated without explicitly modeling such interactions

Advances in Data Mining Knowledge Discovery and Applications

Advances in Data Mining Knowledge Discovery and Applications aims to help data miners, researchers, scholars, and PhD students who wish to apply data mining techniques. The primary contribution of this book is highlighting frontier fields and implementations of the knowledge discovery and data mining. It seems to be same things are repeated again. But in general, same approach and techniques may help us in different fields and expertise areas. This book presents knowledge discovery and data mining applications in two different sections. As known that, data mining covers areas of statistics, machine learning, data management and databases, pattern recognition, artificial intelligence, and other areas. In this book, most of the areas are covered with different data mining applications. The eighteen chapters have been classified in two parts: Knowledge Discovery and Data Mining Applications

Annals of Scientific Society for Assembly, Handling and Industrial Robotics 2021

This Open Access proceedings presents a good overview of the current research landscape of assembly, handling and industrial robotics. The objective of MHI Colloquium is the successful networking at both academic and management level. Thereby, the colloquium focuses an academic exchange at a high level in order to distribute the obtained research results, to determine synergy effects and trends, to connect the actors in person and in conclusion, to strengthen the research field as well as the MHI community. In addition, there is the possibility to become acquatined with the organizing institute. Primary audience is formed by members of the scientific society for assembly, handling and industrial robotics (WGMHI)

3D-in-2D Displays for ATC.

This paper reports on the efforts and accomplishments of the 3D-in-2D Displays for ATC project at the end of Year 1. We describe the invention of 10 novel 3D/2D visualisations that were mostly implemented in the Augmented Reality ARToolkit. These prototype implementations of visualisation and interaction elements can be viewed on the accompanying video. We have identified six candidate design concepts which we will further research and develop. These designs correspond with the early feasibility studies stage of maturity as defined by the NASA Technology Readiness Level framework. We developed the Combination Display Framework from a review of the literature, and used it for analysing display designs in terms of display technique used and how they are combined. The insights we gained from this framework then guided our inventions and the human-centered innovation process we use to iteratively invent. Our designs are based on an understanding of user work practices. We also developed a simple ATC simulator that we used for rapid experimentation and evaluation of design ideas. We expect that if this project continues, the effort in Year 2 and 3 will be focus on maturing the concepts and employment in a operational laboratory settings

Contribution to the organization of ground handling management at airports

La croissance du trafic aérien a rendu critique l’opération de la gestion des plateformes aéroportuaires. Celle-ci fait appel à de nombreux acteurs (autorités aéroportuaires, compagnies aériennes, contrôle du trafic aérien, prestataires de services, …). Le concept d’Airport Collaborative Decision Making (A-CDM) développé depuis une dizaine d’années est basé sur un partage d’informations opérationnelles en temps réel entre les différents acteurs de la plate-forme, permettant de prendre des décisions en commun pour rechercher une utilisation optimale, en toutes conditions, des capacités de l’aéroport. L’objectif principal de cette thèse est de contribuer à l’organisation de la gestion des opérations d’escale dans une plateforme aéroportuaire. Il s’agit de proposer une structure d’organisation de cette opération qui soit compatible avec l’approche A-CDM. La structure proposée introduit un coordinateur des opérations d’escale (GHC) qui joue le rôle d’interface de communication entre les partenaires de l’A-CDM et les différents gestionnaires des opérations d’escale (GHM). Cette structure hiérarchique permet d’une part de partager des informations avec les partenaires de l’A-CDM et d’autre part d’interagir avec les gestionnaires des opérations d’escale (GHM). Les processus de prise de décision basés sur des heuristiques ont été développés à chaque niveau de l’organisation proposée et sont évalués aussi bien dans le cas de conditions nominales que dans le cas de la présence de perturbations majeures. ABSTRACT : The increase of the world air traffic growth of the last decades has generated a permanent challenge for civil aviation authorities, airlines and airports to supply sufficient capacity to provide a safe transportation service with acceptable quality standards. New traffic management practices, such as A-CDM, based on multi-agent and collaborative decision making concepts have been introduced at airports. However, within the turnaround process of aircraft at airports, ground handling management of aircraft has not been developed specifically in the A-CDM approach, even if it has an important role in the fluidity of aircraft operations at airports. The main objective of this thesis dissertation is to contribute to the organisation of the ground handling management at airports. It consists to provide a structure organize the ground handling management compatible with the A -CDM concept. The proposed structure introduces a ground handling coordinator (GHC) which is considered as an interface for communication between the partners of the A -CDM and the different ground handling managers (GHM). This hierarchical structure allows sharing information with partners in the A -CDM on the one side and on the other side, interacting with ground handling managers (GHM). Decision making processes based on heuristics have been developed at each level of the proposed organization and have been also evaluated in the case of nominal conditions and in the case of the presence of major disruptions
