Aiming at the characteristics of batch arrivals production in multivarieties and smallbatch environment, the processing components are classified into keyimportant and unkeyimportmant parts by their usage ratio. According to the principle of Knowledge Engineering, the keyimportant parts production rolling plan is generated by process metaknowledge of keyimportant parts. Unkeyimportant parts production plan is generated by ‘ABC Classification Scheduling Method’. In this way, the rolling plan problem in multivarieties and smallbatch production can be effectively solved.
