Hybrid Scheduling Technology for Emergency Production under Job-Shop Environment

The manufactory must change the production style into flow-style for emergency production to meet the need of modern manufacture formal. This situation has made a contradiction between flow and discrete style. Thus hybrid scheduling technology is proposed to integrate these two styles under the job-shop environment. There are three crucial principles including in this technology: the logical production cell, dynamic priority and delaying strategy. They can be used to optimize the production resource and in the progress of scheduling. At last, the scheduling software is developed supporting by hybrid scheduling technology. The scheduling created by this software is tested by a real instance and is proved to improve the efficiency of production and shorten the make span than before.
