For production workshops with high manual participation,large fluctuations in post processing hours and more production line congestion in the production process,in the case of irregular material consumption,it is difficult for traditional experience-based material distribution scheme to quickly and accurately supply the material missing posts.In order to improve the logistics distribution efficiency of the workshop,a real-time distribution scheme planning method of workshop logistics truck was proposed.Based on the real-time data obtained by the workshop digital twin monitoring system,each production post was assigned a distribution priority,and alternative distribution sequence was obtained based on the priority,and then A* algorithm was used to search for the shortest distribution path.Through the example analysis,comparing with the traditional distribution scheme,the proposed method has shorter planning time and lower distribution costs,the feasibility and superiority of the proposed method is verified.
