Abstract

The invention discloses a production line data preprocessing system which comprises a production line overall state reading module used for reading manufacturing process data information of to-be-machined products on a production line and working load data information of all processes on the production line; and an information preprocessing module is used for processing various types of data information input by the production line overall state reading module, establishing a production line scheduling scheme solution space state diagram and outputting the production line scheduling scheme solution space state diagram to the intelligent dispatching system. According to the invention, each process of a production line and a constraint relationship between the processes are utilized; a production line scheduling scheme solution space state graph of a directed acyclic graph structure is established; according to the technical scheme, searching can be carried out according to the product machining sequence, the solution space scale of the production line dispatching scheme is greatly reduced, a better basis is provided for finding a better production line dispatching scheme within reasonable time, and therefore the efficiency of the intelligent production line dispatching system is obviously improved. The invention further discloses a production line data preprocessing method.

Description

technical field [0001] The present invention relates to the technical field of production line intelligent manufacturing, and more specifically, to a data preprocessing system and method for a production line intelligent dispatching system. Background technique [0002] For example, in the manufacturing process of integrated circuits, multiple processes are included, and each process may have several devices, but the number of devices is limited, so the number of silicon wafers that can be processed simultaneously by each process is limited. Therefore, when there are many silicon wafers to be processed on the production line, and the equipment in a certain process is fully occupied, other silicon wafers that must go through this process will have to wait. Therefore, it is necessary to finely and reasonably schedule the processing sequence of the entire production line to improve the efficiency of the entire production line, thus giving rise to the demand for intelligent disp...
