An original model for dynamic scheduling of information services and material flows in collaborative cyber-physical supply networks is stated and solved with the help of the structure dynamics control approach. The proposed serviceoriented description makes it possible to coordinate the availability of information services and material process schedules simultaneously. It also becomes possible to determine the volume of information services needed for the physical supply processes. In addition, the impact of disruptions in information services on the schedule execution in the physical structure is analysed. The results provide a base for information service scheduling according to an actual physical process execution.
