Abstract: A computer system for creating a work sequence of work items comprises a linked list storage to store multiple first work items and links between the first work items and a first-in-first-out buffer to buffer unscheduled second work items defining a first-out unscheduled second work item. The computer system further comprises a processor. The processor retrieves the first-out unscheduled second work item from the buffer and selects two of the first work items such that an available time between the two of the first work items is greater or equal to the duration of the first-out unscheduled second work item, and stores a link between the first-out unscheduled work item and each of the two selected first work item such that the stored link defines a work sequence and the first-out unscheduled work item is between the two first work items in the work sequence.
