Abstract: In view of the insufficient load of assembly personnel in the multi-model mixed-line production mode of the final assembly line of heavy commercial vehicles, this paper describes a production scheduling method based on structured process, which can calculate the best production models of each production line and the corresponding personnel input according to the annual model planning of the enterprise, and adjust the model mix ratio according to the best efficiency interval of each production line during the order scheduling, to maximize the efficiency of assembly personnel in each production line. Through practice, this method can effectively reduce the number of assembly personnel and improve production efficiency, and can be widely used in manufacturing enterprises to improve the efficiency of multi-variety mixed-line production lines and reduce production costs.
