Abstract

The invention relates to an optimized dispatching method of the photosensitive resistance welding process in multilayer printed circuit board manufacturing, and belongs to the technical field of intelligent optimized dispatching in a manufacturing shop. According to the optimized dispatching method, a dispatching module and an optimization object in the photosensitive resistance welding process are determined, and an optimized dispatching method based on a population increment learning algorithm is used for optimizing the optimization object; the dispatching module is established according to the processing completed time of all circuit boards on all machines, and meanwhile the optimization object is the minimum earliest completed time. According to the optimized dispatching method of the photosensitive resistance welding process in the multilayer printed circuit board manufacturing, expression of a PSR process is made clear and accurate, a probabilistic model can achieve good balance on precision and complexity, the global search of the algorithm achieves more guidance, the historical information of superior individuals can be effectively utilized, and it is also can be guaranteed that the global search of the algorithm has a certain width, the algorithm can better jump out the local optimum, so that the algorithm can search more regions, the local development capacity of the algorithm is improved, and the quality of a solution can be further improved.
