Abstract

The invention discloses a real-time job shop scheduling control method in a complicated production environment. The method comprises the following steps: S101, a job shop production environment multi-agent model is initialized; S102, scheduling triggering events are registered; S103, after any event in the step S102 is triggered, a plurality of workpiece agents are scheduled sequentially according to the real-time job shop state; and S104, as for each workpiece agent, after the scheduling is completed, if a cache task execution condition is met, the cache task is executed, or otherwise, the cache task execution condition is waited to be met. Thus, real-time and dynamic multi-workpiece scheduling in the complicated production environment can be effectively realized; and when production disturbance factors such as equipment fault and emergency orders are handled, the system operation efficiency can be effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of workshop scheduling control, in particular to a real-time control method for workshop scheduling in a complex production environment. Background technique [0002] In recent years, as the manufacturing industry is facing the serious test of small batches, customization, and unstable order flow, the Job-Shop Scheduling Problem (JSP) has more and more uncertainties. The real-time, dynamic, multi-objective and other aspects of the workshop scheduling control method put forward higher requirements, in order to be closer to the actual production situation. At present, most of the researches on the shop-shop scheduling problem have the following problems: (1) The parameters in the production process are regarded as exact values. In the traditional study of shop-shop scheduling problems, workpiece arrival time, transportation time, processing time, etc. are all regarded as exact values. In fact, due to uncerta...
