Description

technical field [0001] The invention relates to the field of automatic production scheduling, in particular to a dynamic scheduling device for a semiconductor production line. Background technique [0002] With the rapid development of information technology, the semiconductor manufacturing industry has become the pillar industry of the national economy and the mainstream of the global high-tech industry. The semiconductor production line scheduling problem is the core content of the production line management of semiconductor enterprises, and it is also the key to improving the core competitiveness of enterprises. Since the semiconductor production line is a dynamic system, there are various random and uncertain factors, such as machine failure, emergency production task insertion, etc. Therefore, the on-site management of the semiconductor production line needs to have the requirement of dynamic scheduling, that is, according to the real-time The production status quickly...
