Problems solved by technology

[0005] However, these solving algorithms are not universal, and a specific algorithm can only achieve better effective results in a certain type of shop-shop scheduling problem.
For the specific job-shop scheduling problem, the above solution algorithm can only provide a rough solution framework, and a specific solution solution must be designed according to the characteristics of the specific problem

Abstract

The invention discloses a dynamic scheduling method of a track type automatic guiding vehicle based on segmentation optimization of a genetic algorithm. The method comprises the following steps: performing segmentation optimization on a parking sequence of the track type automatic guiding vehicle at various parkable positions according to state parameters of numerical control machine tools and preset processing parameters; encoding: encoding the parking positions of the track type automatic guiding vehicle in the future N times into a gene string with a length N; decoding: using a ratio of a workpiece number completed in a process when the track type automatic guiding vehicle moves for N steps to the consumed time as gene string fitness; and performing crossover, mutation and retention ofelite gene string operations on the genetic algorithm, obtaining an optimal gene string through multiple rounds of evolution, and using the optimal gene string as the movement mode of the track type automatic guiding vehicle in the future N times. The algorithm re-optimizes the movement trajectory of the RGV in the future N times when finding that the CNC is faulty or restores from the fault, so that an RGV scheduling scheme can be automatically adjusted according to the change of the system parameters, and CNC random faults and fault restoration can be adaptive.

Description

technical field [0001] The present disclosure relates to the technical field of industrial intelligent processing, in particular to a dynamic scheduling method for track-type automatic guided vehicles based on genetic algorithm segmentation optimization. Background technique [0002] A typical intelligent processing system generally consists of a guide car, several CNC machine tools and related auxiliary equipment. A CNC machine tool can only process one material with one tool at a time. If the material processing process requires two processes, different CNC machine tools are required to install different tools to complete the processing separately. The guide car can move and stop waiting on the straight track according to the instructions, and can only perform one of the operations of moving, stopping and waiting, loading and unloading and cleaning at the same time, and these operations will take a certain amount of time. [0003] For the intelligent processing system mod...
