Item type:Publication, Access status: without files , Disruption management with digital assistance systems : a generic approach for the product lifecycle(GITO mbH Verlag für Industrielle Informationstechnik und Organisation, 2023-04); ; ; In the production and operation of complex, one-of-a-kind products, disruptions inevitably occur. In practice, there are often deficits in terms of transparency and information flow when it comes to disruption management. Digital assistance systems facilitate disruption documentation: they increase the quality of information by locating it in the CAD model and in the overall product plan, thus accelerating targeted fault elimination. A generic data model makes it possible to use digital assistance systems for different products, trades and processes and in different product life phases.Publicationtype: Journal Article71 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Tool or hassle? - Production workers evaluation of the potential of digital assistance systems on the shopfloor in shipbuilding projects(Taylor & Francis, 2023-01-02); ; ; Technology development opens up for new possibilities to facilitate the production processes through digital information systems. To optimize the systems’ value, the form, content, and medium must fit the needs of the workers. This article aims to contribute to the discussion on value, use and design of digital assistance systems for production. It presents empirical data from a case study at a Norwegian shipyard, on production workers’ perception of coordinative challenges, and the value (including content) of digital assistance systems in complex shipbuilding projects. A quantitative survey among supervisors and operators at the shop floor was conducted twice due to different circumstances at the yard. These variations in circumstances are valuable to enable an evaluation of the workers’ perception of coordinative challenges and digital solutions in different situations. The findings indicate a pronounced positive attitude towards the potential of digital systems. Moreover, the role of supervisors and operators in coordinative challenges leads to different requirements to the solutions. The results from this study will have both industrial and scientific implications, as they provide valuable insights to help develop user-friendly systems that aid both workers and the company in terms of efficiency and accurate communication.Publicationtype: Journal ArticleScopus© Citations 1 76 208 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Digitale Assistenzsysteme für kollaboratives Arbeiten in der Unikatproduktion(2023); The production of complex, unique products requires the cooperation of many different parties. If a disruption occurs in a subprocess, it affects parallel or subsequent work processes and delays the overall process. The digital assistance system for collaborative work presented in this thesis offers situation-specific information provision for workers and enables informative disruption reports to be created with just a few clicks. Stakeholders in relevant construction areas are automatically notified and site managers can clearly manage, prioritize, and troubleshoot the disruptions. The system greatly increases transparency in the overall process context and con-tributes to reducing lead times.Publicationtype: Doctoral Thesis520 596 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: without files , Automated generation and low-effort authoring of commissioning content in the maritime industry(Royal Institution of Naval Architects (RINA), 2022-09-15); ; ; ; Commissioning in the maritime industry is a long crucial phase in which all essential components in the ship are tested for faults and defects before a final acceptance form is signed by the client. Due to the variety of components in a ship and the complex hierarchical structure of such components, it is typical to have thousands of tests that should be performed throughout the commissioning phase. For every new ship, commissioning planners initially spend hours preparing the commissioning tests by reading technical documents, extracting relevant information, and applying the gathered knowledge to the unique equipment configuration in the ship. This leads to high preparation efforts and planning mistakes, e.g., unconsidered dependencies, and as a result, commissioning, and the shipbuilding process as a whole may be delayed. This paper lays the foundation for automating the process of authoring commissioning content for maritime productions. The paper presents a digital modeling approach for ship components, which facilitates the development of commissioning-specialized software. The model shown in this paper takes textual and geometrical information of ship components as input data and produces generalized commissioning templates that can be used to generate commissioning tests automatically.Publicationtype: Journal Article48 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Digitalization of maritime commissioning : a system for automatic content creation and augmented reality-based commissioning execution(Technische Universität Hamburg-Harburg, 2022-06); ; ; Ship commissioning is an essential process in the maritime industry where all components in the ship are tested to ensure that client requirements and specifications are fulfilled. Commissioning consists of three main phases: preparation, execution, and documentation. Commissioning test preparation and execution require a long time, high effort, and experience to perform. To enhance the process of commissioning, by supporting commissioning planners and engineers, a comprehensive digital com-missioning system was developed. The system presented in this paper employs an automation approach for more efficient preparation of commissioning content, and uses Augmented Reality for commission-ing execution.Publicationtype: Conference Paper55 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: without files , Consistent Maintenance Order Processing with Digital Assistance Systems(2021-09); Augmented reality-based digital assistance systems have proven their potential to support with instructions considering numerous application scenarios in the product life cycle. For the maintenance of machines and plants, however, their use becomes particularly efficient if the diagnosis at the operator’s site can be effectively supported, so that the service provider and his experts can make accurate diagnoses for this maintenance job, plan the execution including the spare parts logistics precisely, and document as well as billing the maintenance case with low effort. For this purpose, a modular digital assistance system is presented that provides support adapted to the process phases.Publicationtype: Conference Paper49 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Digitale Assistenzsysteme in der Industrie : Visualisierungskonzept(2021-05-11)Digitale Assistenzsysteme haben das Potential die papierbasierte Informations- und Kommunikationsbasis in der Industrie zu ersetzen. Hierbei ist die Digitalisierung keineswegs ein Selbstzweck, denn die Systeme bieten die Flexibilität die bereitgestellten Informationen und Funktionen präzise am Nutzer und dem jeweiligen Anwendungsfall auszurichten. Der dadurch entstehende Mehrwert für industrielle Prozesse wie die Montage [Frie16] oder die Instandhaltung [Melu19] komplexer Produkte konnten bereits hinlänglich nachgewiesen werden. Bei der Gestaltung der primär informatorischen Assistenzsysteme stellt sich je-doch stets die Frage eines unter kognitiv-ergonomischen Gesichtspunkten sinnvoll gestalteten Bedienkonzeptes [Jesk20]. Unternehmen neigen dazu, unstrukturierte Informationen in zu großen Mengen bereitzustellen, die Bereitstellung zu wenig am Empfänger auszurichten und allgemein zu wenig aus Sicht der Bezugsgruppe zu denken [Mast20]. Im Folgenden werden ein empfängerorientiertes Visualisierungskonzept zur Abbildung grundlegender Informationsbausteine sowie Kommunikationsfunktionen für digitale Assistenzsysteme vorgestellt.Publicationtype: Working Paper486 732 - Some of the metrics are blocked by yourconsent settings
