Härer, FelixFelixHärer2019-09-192019-01-102018https://fis.uni-bamberg.de/handle/uniba/44162For supporting the conceptualization and the management of enterprise models in a decentralized manner, this paper introduces an approach based on model versioning and blockchain technologies. The main contribution is twofold, consisting of a., the creation of models for inter-organizational business processes in a decentralized environment, and b., means for tracking process instances using meta-data at run time. Models for business processes, workflows, and instance states are collaboratively created as part of a decentralized architecture. Based on this approach, a hierarchical versioning and modeling approach is employed in order to create and manage public and private models in a transactional fashion. For forming relationships among decentralized participants, semi-formal models linked to a blockchain are suggested. The approach is evaluated with a supply chain use case and demonstrated in an implemented modeling tool.engCollaborative ModelingDecentralizationModel ManagementBlockchainModel Versioningconferenceobjecthttps://aisel.aisnet.org/ecis2018_rp/55/
