Abstract: Affected Batch Rescheduling (AI3R) Algorithm for multipurpose batch process was proposed in order to　tackle delay of batch. The comprehension of quality and stability was used for the performance index of rescheduling solution. AI3R algorithm delays all affected batches based on processes defined in state task network (STN). Simulation case illustrated that AI3R algorithm is better than Right Shift Rescheduling (RSR) algorithm on makespan and the total delay time of start time of affected batches.
