The shift towards mass customization in production and technological advancements lead to new manufacturing paradigms. Such paradigms facilitate the distribution of production to distributed companies, located all around the globe, essentially creating a cloud-based manufacturing platform. In such a system, manufactures may provide their production facilities as services to others – leading to the paradigm of Manufacturing-as-a-Service (MaaS). One major challenge in MaaS is the discovery of manufacturing resources and the distribution of orders to them. We propose an ontology based template matching method to find fitting manufacturing resources. Based on this selection we introduce a multi agent-based auction system for distributing orders and production planning. To illustrate its practical applicability we integrated the proposed approach in an existing cloud manufacturing platform.
