Abstract: An ad hoc supply chain collaborative computing environment management method includes selecting a collaboration model from amongst several models and establishing the environment in accordance with the selected model including defining a knowledge graph, a set of expected events to be received in an event log, and one or more predictive functions operating upon the different events in the event log to produce predictive values. The method also includes, registering actors in a supply chain as authenticated publishers or subscribers to the event log of different events published by different authenticated computing systems of the actors, authenticating different ones of the registered different actors prior the different actors publishing events to the event log, triggering predictive functions for newly published ones of the events in order to produce predictive values and providing read-only access to different states of the entities of the knowledge graph to authenticated subscribers.

Abstract: A supply chain message routing method includes registering in a supply chain information sharing data processing system, a multiplicity of different actors in a supply chain and generating a knowledge graph that includes different entities representative of corresponding ones of the actors joined by edges representative of relationships between respectively joined ones of the entities. The knowledge graph additionally indicates a role for each of the actors. The method also includes monitoring an event log of events published thereto by the different actors and responds to a new event posted to the event log by extracting from the event, keywords pertaining to the supply chain, mapping the keywords to one or more roles of the supply chain, identifying a set of entities in the knowledge graph corresponding to the roles, formulating a message from the new event, and publishing the formulated message to each entity in the identified set.
