schedule evaluationthe schedules are evaluated as per to the criterion weighted loss of slack now let t0si be the slack time buffer of job i as per
schedule selectionof the p excellent continuations q first operations are scheduled this offers p latest partial schedules after that step 1 is
schedule evaluationeach continuations of a partial schedule that are produced in step 1 are ranked as per to their respective cost function this cost
generation of continuationit is assumed that a partial schedule which may be empty schedule is given for this partial schedule a number of possible
restricted search over all possible schedulingall options to this approach aim to calculate a schedule for a specific number of operations and after
predictive control algorithmsescaping scheduling errors via partial look-aheadsince previously mentioned above the heuristic priority rules that are
newer approaches to on-line scheduling the on-line scheduling has established to be superior option than off-line scheduling upon the shop floor
results for the underlying problemthe rules mentioned above and several variants of these rules that became out to be inferior are tested for eight
