Abstract

The invention relates to a semiconductor production line self-adaptation dynamic dispatching device which is connected with a manufacturing execution system. The dispatching device comprises a dispatching management device, a learning device and a display device. The dispatching management device is connected with the manufacturing execution system, and the dispatching management device, the learning device and the display device are connected in sequence. The dispatching management device acquires a list of current workpieces to be dispatched through the manufacturing execution system and transmits the list of the current workpieces to be dispatched to the learning device, the learning device calculates machining priorities of the current workpieces to be dispatched according to a dispatching rule stored in the learning device and transmits the priorities of the current workpieces to be dispatched to the display device, and the display device displays the priorities of the current workpieces to be dispatched. Compared with the prior art, the semiconductor production line self-adaptation dynamic dispatching device has the advantages of being capable of improving workpiece machining efficiency and bottleneck equipment use ratios, good in dynamic regulation performance, and the like.

Description

technical field [0001] The invention relates to the field of production management of microelectronics manufacturing and other discrete manufacturing production systems, in particular to an adaptive dynamic scheduling device for a semiconductor production line, which is used for real-time decision-making on the priority of processing multiple workpieces on the equipment, and is useful for improving the operation of the semiconductor production line Performance matters. Background technique [0002] In the production system using assembly line workshop processing, a conveyor system transports the work-in-process (WIP) along the workbench, and at each workbench, a different process of WIP is completed. In theory, the WIP visits each station once during a start-to-finish machining run. A semiconductor production line is different from most production systems that use assembly-line shop processing. In the semiconductor production line, WIP may visit the same workbench several ...
