Abstract

Systems, methods, and computer program products synchronize product fabrication schedules with supplier schedules. A fabrication schedule is obtained from a fabricator data processing system, and supplier schedules are obtained from respective supplier data processing systems. Restrictive links are established between the fabrication schedule and the supplier schedules. Each restrictive link defines the supplier that will perform a work stage, and can also define the starting and ending times for both fabrication and supplier schedules. Activities in a critical path schedule having an actual ending time that is later than a projected ending time are identified. Float time is assigned to projected starting times of downstream activities not on the critical path such that actual starting times of the downstream activities are identical to projected starting times.
