Product quantity statistical method and product quantity statistical device in production process

Abstract

The invention provides a product quantity statistical method and a product quantity statistical device in a production process, and the method comprises the steps: determining whether a second constraint condition corresponding to a first constraint condition exists or not for any changed first constraint condition in target equipment constraints with conditions changed; if yes, the first constraint condition is compared with the second constraint condition, and whether the first constraint condition meets a preset change condition or not is determined; if at least one first constraint condition meeting a preset change condition exists in the target equipment constraint, setting a new counting key for the target equipment constraint; and determining at least one new count value associated with the new count key, and continuously recording the product quantity of the product batch corresponding to the new count value after the condition change in each new count value. In this way, the number statistics efficiency can be improved, and the problems of product number statistics errors and statistics missing occurring when the device constraint changes are solved.

Description

technical field [0001] The present application relates to the technical field of production control, in particular to a product quantity statistic method and a product quantity statistic device in the production process. Background technique [0002] With the development of science and technology, in modern manufacturing factories, Manufacturing Execution System (MES) is usually built to optimize the management of the entire production process from order placement to product completion through information transmission. In manufacturing factories, because the manufacturing methods of products are often more complicated, it is necessary to establish equipment constraints for each equipment in the MES system to make equipment production meet management requirements. Wherein, each equipment constraint includes at least one constraint condition; each equipment constraint is used to allow or prohibit the target equipment from producing the product batch when the product batch sati...

AI Technical Summary

Problems solved by technology

The existing product quantity statistics method cannot change the statistical value according to the change of the constraint conditions, which makes the MES system make mistakes in the statistics of the product quantity, resulting in statistical omissions; there are also quantity statistics methods that set their own statistical values ​​for each constraint condition, There is a large amount of repeated statistical data in the MES system, which takes up a lot of storage and computing resources, resulting in low statistical efficiency

Therefore, the existing counting method of product quantity in the production process can no longer meet the needs of production and management.
