Abstract
The paper describes a reference architecture for open marketplaces to be used for networked stakeholders in industrial production ecosystems. The motivation for such an endeavor comes from the idea to apply the basic principle of the platform economy to offer functions of an asset “as a service” to industrial production, including the associated supply chain networks. Currently, commercial offers of “production as a service” usually lead to proprietary systems with the risk of platform vendor lock-ins. Hence, there is a need for an open approach that relies upon international (emerging) standards, especially those from IETF, IEC, the Plattform Industrie 4.0 and the International Data Spaces Association (IDSA). The presented approach enables federation of marketplaces according to well-defined interfaces. This article proposes a technology-independent open architecture derived from functional and non-functional system requirements and driven by the idea of the Smart Factory Web, a testbed of the Industrial Internet Consortium (IIC). Furthermore, the architecture of the Smart Factory Web (SFW) platform is presented and assessed against the current and future demands of open federated marketplaces for industrial production ecosystems.
Highlights
The Smart Factory Web is described on two levels: firstly, as a blueprint architecture for a Web of Smart Factories forming an industrial marketplace in a federated ecosystem, and secondly, as a software system that realizes this idea based upon international standards
In order to enable the Smart Factory Web (SFW) to interact with similar platforms, the SFW itself should be made available via Administration Shell (AAS) interfaces
The article describes an architectural proposal for marketplaces in the domain of industrial production that follows the paradigms of the platform economy
