Production line process simulation optimization method and system

Abstract

The invention relates to a production line process simulation optimization method and system. The method comprises the following steps: establishing a production line simulation model of a virtual production line based on a physical production line; collecting current equipment operation state data and historical equipment operation state data of the physical production line; performing data synchronization on the physical production line and the virtual production line based on the historical operation state data of the equipment, the current operation state data of the equipment and the target operation state data of the equipment; performing real-time simulation optimization on the production line simulation model based on the virtual production line after data synchronization to obtain a simulation optimization result, and generating an optimization control instruction according to the simulation optimization result; and outputting the optimization control instruction to the physical production line so as to carry out optimization control on the physical production line. The method has the effect of realizing coordinated optimization control between a batch production mode and a small sample trial production mode.

Description

technical field [0001] The present application relates to the technical field of discrete manufacturing, in particular to a production line process simulation optimization method and system. Background technique [0002] Discrete manufacturing means that there is basically no material change in the production process, but only the shape and combination of materials change, that is, the final product is assembled from various materials, and there is a definite quantity ratio between the product and the required materials. Typical industries include military manufacturing, machinery manufacturing, automobile manufacturing, and home appliance manufacturing. [0003] For example, the manufacturing process of some military digital production lines is a typical discrete manufacturing process, which requires both mass production of mature models and small batch trial production of scientific research models, making production change a typical feature of military manufacturing enter...
