Das Industrie-4.0-Anwendungsszenario „Durchgängiges und dynamisches Engineering von Anlagen“ [1] basiert im Kern auf der Existenz eines digitalen Modells der Anlage. Das durchgängige digitale Modell verändert die Kollaboration bestehender Rollen und bringt neue Rollen zur Erstellung, Pflege und Auswertung des Modells im Wertschöpfungsnetz ins Spiel. Diese Veränderungen werden im vorliegenden Beitrag unter dem Gesichtspunkt „Business Viewpoint“ beschrieben.

AbstractThe Technical Division “Engineering and Operation of automated plants” of the VDI-/VDE-GMA (German Association of Measurement and Automation) elaborates new approaches for an efficient engineering and operation of equipment and automated plants. Within this Division, technical committee 6.12 “Integrated engineering of automated systems” has analyzed and refined the concept of an integrated plant model over all phases of a plant’s life, since this has the potential to generate high synergy potentials by means of model reuse and early integration. Previous work of the technical committee 6.12 has addressed the changes in the value network from a business perspective. The present contribution describes how an integrated plant model should be built, maintained and used. The approach is explained in a generic way from a usage view, by the description of the system under consideration, the acting technical stakeholders and the activities that can, or must, be carried out. The approach is then elucidated by means of an example.

The necessity to improve the current automation concepts for cost reduction in plant engineering represents a widely discussed problem. Although research has been developing solutions for this problem area for quite some time on the basis of decentralized automation concepts, industrial companies have been showing reluctance concerning their broad application in practice. This contribution discusses the potential for use of decentralized automation of industrial plants in the context of strategic developments. The ramifications of such technological perspectives to the different stakeholders in an industrial life cycle, their interests and their processes are discussed and a method for the evaluation of decentralized solutions over their entire life cycle is presented, offering a basis for a well founded assessment of their cost effectiveness.
