Online energy consumption optimization method for rework production systems

Abstract

Aiming at the problems of high equipment composition complexity, long idle time of idle machines, and difficulty in online optimization of energy consumption in the production system that adopts the “immediate rework” mechanism, an online energy consumption optimization method for rework production systems is proposed. A digital model of production system energy consumption for the “immediate rework” mechanism is established, and real-time data is integrated to realize online energy consumption optimization based on the optimal buffer threshold. Taking the module production line of a battery workshop of a new energy vehicle factory as the application object, the online energy consumption optimization system of the rework production line of the workshop is designed and developed, and the effectiveness and feasibility of the proposed method are verified.
