Abstract: To study a job identification problem in the rolling horizon optimal scheduling window under dynamic processing environment. To present a job identification method of rolling scheduling based on dynamic rough sets and its element transfer characteristic, in case of the machine failure, the due data change of jobs and the urgent jobs. Using the proposed method, not only the dynamic processing environment is adapted and a satisfied scheduling result is obtained, but also the rescheduling degree and the problem dimension are decreased. The simulation results demonstrate the availability of this method.

Key words: Dynamic identification, Dynamic rough sets, Element transfer, Rolling scheduling
