Abstract

The embodiment of the invention provides a root cause positioning method and device for abnormal production, equipment, a medium and a product. The method comprises the following steps: acquiring equipment resume information and reject ratio information of a target batch of products; constructing a plurality of virtual parallel units along a target path based on resume information of a target level in the device resume information; based on the equipment resume information and the reject ratio information of the target batch of products, obtaining the defective concentration degree value of each virtual parallel unit; and determining an abnormal root cause based on the bad concentration degree value of each virtual parallel unit. The method can improve the accuracy of bad root cause positioning; especially for the situation that data is less when unexpected faults occur in the product production process, the accuracy of positioning the bad root causes can be remarkably improved, and the technical problem that the accuracy of positioning the root causes in the product production process is low is solved.

Description

technical field [0001] The invention relates to the technical field of production control, in particular to a root cause location method, device, equipment, medium and product for abnormal production. Background technique [0002] The product production process (for example, panel production) generally includes multiple production links, and each production process involves a large number of complex processes, and these processes are completed by a series of equipment configured in series or in parallel. In actual production, in the face of large-scale production equipment, it becomes more difficult to carry out effective equipment control and positioning analysis that affects product quality. Especially when a sudden abnormal fault occurs, the accuracy of root cause location is low. Contents of the invention [0003] The main purpose of this application is to provide a method, device, equipment, medium and product for root cause location of production abnormalities, and ...
