    Customers demand for individualized products leads to a large variety of different products in small series and single-unit production. A high flexibility pressure in product creation is one result of this trend. In order to counteract the pressure, the information steadily increasing by Industry 4.0 must be made available at the workplace. Additionally, a better exchange of information between product development, production planning and production is necessary. The improvement of individual systems, like CAD, PDM, ERP and MES, can only achieve this to a limited extent. Since they mostly use systems from different manufacturers, the necessary deeper integration of information is only feasible for SMEs to a limited extend. The presented control desk helps to ensure a more flexible product creation as well as information exchange. It captures information from different IT systems in the production process and presents them integrated, task-oriented and oriented to the user's mental model, e.g. information of the production combined with the 3D model of product parts, or information about product development on the 3D model of the production. The solution is a digital 3D model of the manufacturing environment, which is enriched by billboards for a quick information overview and web service windows to access detailed MES and PDM information. By this, the level of abstraction can be reduced and reacts to changed requirements in the short term, making informed decisions. The interaction with the control stands utilizes the touch skills of mobile and fixed systems such as smartphones, tablets and multitouch tables.

    As a result of the growing demand for highly customized and individual products, companies need to enable flexible and intelligent manufacturing systems. Such new production systems, so called ""Cyber Physical Productions Systems"" (CPPS) aim the vision of interlinked and autonomous production. The research project VIB-SHP envisions controller validation of manufacturing system covering aspects of asynchronous communicating, intelligent and autonomous acting production equipment and a service based production IT. To enable manufacturing system designers to validate CPPS, a software framework for virtual prototyping has been developed. A multi-disciplinary construction kit integrates discipline specific models and manages them in a PLM solution. The usage of the construction kit enables manufacturing designers to apply virtual technologies and ease the integration in the production-IT. The presented approach resolves the sequential design process for the development of mechanical, electric and software elements and ensures the consistency of these models. With the help of a BOM- and signal-based alignment of the discipline specific models in an integrated mechatronic product model, the communication of design status and changes is improved. The re-use of already specified and designed modules enable quick behavior modeling, code evaluation as well as tangible user interaction with the virtualized assembly system.

    In Systementwicklungsprojekten kommt es häufig vor, dass Änderungen an Systemelementen vorgenommen werden müssen, die potentielle Auswirkungen auf andere Systemelemente und/oder den Projektplan haben. In gängigen Systems Engineering Handbüchern gibt es daher eine Reihe von Hinweisen, wie über solche Änderungen entschieden und wie sie geeignet gesteuert werden können. Dabei fehlt es jedoch an Vorschlägen, woher die Informationen, die für die Abschätzung von Änderungsfolgen notwendig sind, stammen sollen. In diesem Beitrag wird deshalb ein Ansatz vorgestellt, wie Entscheidungen über Änderungsvorschläge durch die geeignete Bereitstellung von Informationen aus heterogenen Datenquellen unterstützt werden können. Dabei kommt ein Datenintegrationsansatz zum Einsatz, in dem eine Ontologie beschreibt, welche Informationen aus unterschiedlichen IT-Systemen für die Entscheidungsunterstützung relevant sind, und in welchem Zusammenhang zwischen diesen Informationen bestehen können. Auf diese Art und Weise können die Aufwände für die Informationsbeschaffung deutlich reduziert werden und es kann schneller und fundierter über Änderungen entschieden werden.

    Produkt-Service System (PSS) definieren ein neuartiges Produktverständnis aus Sachleistungen (d.h. technischen Produkten) und Dienstleistungen. Die Kombination beider Elemente ermöglicht maßgeschneiderte Problemlösungen, um genauer auf individuelle Kundenbedürfnisse eingehen zu können. Mit Dienstleistungen als integriertem Bestandteil der Lösung ist es möglich, neue Geschäftsbeziehungen zu Kunden zu definieren, die weit über den Produktverkauf und Aftersales Dienstleistungen hinausgehen. Hybride Leistungsbündel (HLB) sind eine spezielle Form von PSS mit einem Fokus auf Lösungen für industrielle Geschäftskunden. Bei der Entwicklung hybrider Leistungsbündel (HLB) werden Lösungen aus Produkten und Dienstleistungen konzipiert und in enger Abstimmung ausgestaltet, um Kunden nicht mehr nur ein Produkt, sondern viel mehr eine Leistung anbieten zu können. Dabei werden dem Kunden beispielsweise die Inbetriebnahme, Instandhaltung, Wartung von Produkten abgenommen, so dass dieser sich auf deren Nutzung konzentrieren kann. Die Entwicklung von HLB legt dabei den Fokus auf Themen und Herausforderungen, die in gängigen Produktentwicklungsmethoden nur wenig Betrachtung finden. Um diesen HLB-spezifischen Themenschwerpunkten Rechnung zu tragen, wird ein auf diese Zielstellung ausgelegter HLB-Entwicklungsprozess vorgestellt. Anschließend wird erklärt, warum die HLB-Entwicklung als ein Spezialfall des Systems Engineering verstanden werden kann, und wie sich beide Ansätze gegenseitig ergänzen können. Als Grundlage für diese Betrachtung wird das Systems Engineering Handbuch der INCOSE verwendet.

    Mass customization is an approach that provides methodologies for the development of customized products while still profiting from the benefits of mass production such as economies of scale. Today, mass customization approaches have found their way into different industries such as clothes and furniture but also, to some extent and named differently, into more complex products like cars. Products like busses, trains, or aircrafts are not particularly known for applying similar approaches. They deal with complex systems that are highly regulated by legal requirements and thus seem to be restricted with respect to their possible degree of customization. This paper presents results from a study that was conducted in order to analyze applied practices in these industries. One of the goals of the study was to detect limitations of todays mass customization approaches that prevent an easy applicability. Configuration and customization approaches in the airplane cabin design, in the bus and in the train industry were investigated and compared. Finally, shortcomings in the applied practices and in the supporting solutions were identified and suggestions for improvements were formulated.

    Along the product development process concurrent engineering teams repeatedly create new product data and exchange it among each other as a logical input for subsequent engineering activities. Almost every piece of product data logically builds on another. However, usually product data is scattered over different, domain-specific IT systems and this physical separation is a challenge for product developers and IT experts. Since the management of logical interrelations between distributed product data is costly, such semantic links are often not modelled explicitly. Hence, engineers need to know these interrelations implicitly in order to ensure logical consistency of the overall product model. In this paper an approach for efficient semantic data integration and its application to an exemplary use case, knowledge-based test planning, is presented. It is supported by an integration framework that uses ontologies for interlinking different systems of virtual product creation. The paper also presents the findings of a case study on the process of defining a mapping between a requirements ontology and a domain-specific data exchange format, the Requirements Interchange Format (ReqIF).

    Today, product development is characterized by cross-company collaboration and an intensive exchange of product data. Engineers typically apply a multitude of digital engineering tools and act in diverse engineering processes. In a current study, the culture of todays collaborative product development was investigated in significant detail. The questions are: How do engineers work today? Which tasks play a major role in their daily business? How much time is remaining for core engineering tasks like design, calculation and design validation? How do engineers assess their workplace (environment)? Where are opportunities for enhancement of processes and digital engineering tools? In total, 1,401 engineers answered the questionnaires. Details of the study and selected findings are presente d in this paper. Interesting findings are related to collaborative engineering and engineering design, Product Data and Lifecycle Management (PDM/PLM), virtual product creation, information and process management, and new media in engineering design.
