SUMMARY:Use of a multi agent system to leverage knowledge from different stakeholders in open-die forging
DESCRIPTION:In recent years, many production processes, including open-die forging, have been digitalized, resulting in process data and process knowledge being available in many places. However, this knowledge is often decentralized, e.g., in individual companies, and cannot be consolidated in one database easily due to stakeholder interests (secrecy, ownership, etc.) or the volume of data. In order to nevertheless draw added value from all available process data, a multi-agent system (MAS) is presented using the example of an open-die forging. Based on an ontology, the individual agents can communicate semantically with each other to exchange information. A top-level service broker manages the available services and forms the link between agents and user interface. 
In this manuscript, a MAS-demonstrator is presented that provides two example services, the material choice of a forging as well as the design of an optimal pass schedule. For this, the MAS uses process data along the production chain of an open-die forging as well as an ontology designed to represent this production related data. In the MAS multiple agents are included, representing different stake holders along the production chain like the steel retailer, the steel producer and the open-die forge.
