However, this theorem is only true in the absence of cycle resources or routing loops. Loops of the product flow may cause unbalanced behaviour for the cell in an unforeseeable or at least complex way. Balancing a cycle shop, therefore, needs a hierarchical approach: First, create a balanced rough-cut schedule for processes per work cell based on the work cell throughput diagram; second, create a detailed schedule for operations per cycle resource based on resource Gantt charts; and third, integrate both schedules in such a way as to optimize shop performance and to avoid collisions among processes and operations. In our approach, all three steps are supported by a process model called collision functions which originate in correlation theory. By this unified representation, job scheduling, resource allocation and process coordination are integrated in a convincing way. The optimisation method is applicable to flow, job and cycle shops both for stationary and dynamic schedules.enAutomation SystemsCorrelation SchedulingModelling and SimulationProduction planningResource planningTechnology::620: Engineering::620.1: Engineering Mechanics and Materials ScienceDynamic load balancing of cycle shops based on correlation functionsConference PaperConference Paper
