The invention belongs to the technical field of automobile manufacturing, and particularly discloses an intelligent flexible production scheduling method and
system for automobile orders, and the method comprises the following steps: collecting order demands of a user; according to the order delivery time requirement of a user, reversely deducing production plans of a
coating workshop and a
welding workshop by taking the
general assembly workshop as a starting point to obtain a production plan of a
production line; according to the demand within a period of sales, in combination with the material arrival
rhythm, the workshop capacity and the sales demand successive date factor,
daily production vehicles are discharged, and according to the selected
daily production vehicle distribution result and the final
assembly lean production proportion requirement, constraint conditions are set, and
coating production sorting and scheduling calculation are carried out; and on the basis of the scheduling, a
welding vehicle
queue plan is generated in combination with a
coating workshop production plan in a user order demand. By adopting the technical scheme, production scheduling is carried out by using a production scheduling reverse pushing mode based on the production characteristics of the automobile orders, flexible production scheduling of the automobile orders is realized, and the efficiency is improved.
