Research on multi-project resource conflict resolution method based on delay Petri-net

In view of the key resource conflict problems in multi-project management, this paper combines the delay Petri network with the actual operation process of enterprises, and establishes a resource conflict delay Petri network model for the description and analysis of the multi-project management process.Based on this model and combined with the project key chain, this paper proposes a multi-project resource conflict resolution method.Finally, the local conflict resolution process of multi-project resources proved the effectiveness of the proposed method and provides reference for multi-project management.
