Abstract

The invention belongs to the technical field of information and control, and particularly relates to an integrated scheduling method for disassembling, preprocessing and reassembling of a remanufacturing system. The integrated scheduling method comprises the steps of building an integrated scheduling model of the remanufacturing system according to the production process of disassembling, preprocessing and reassembling of the remanufacturing system, designing a learning mechanism based frog leaping algorithm to perform solving, and finally establishing an integrated scheduling method for disassembling, preprocessing and reassembling of the remanufacturing system. The invention provides a scheduling method capable of realizing global optimization of disassembling, preprocessing and reassembling of the remanufacturing system in allusion to a problem that a disassembling workshop, a preprocessing workshop and a reassembling workshop are uncoordinated and inconsistent in production process because of independent scheduling of the three workshops of the remanufacturing system, thereby achieving orderly connection of the disassembling, preprocessing and reassembling process.

Description

[0001] technical background [0002] The invention belongs to the technical field of information and control, and in particular relates to an integrated scheduling method for dismantling, preprocessing and reassembling of a remanufacturing system. Background technique [0003] Remanufacturing is a typical production model to achieve sustainable development of energy saving and environmental protection. It can redevelop and utilize the valuable resources contained in waste products, alleviate the contradiction between large resource demand and resource shortage, and reduce the impact of a large number of waste products on the environment. pollution and hazards. A general remanufacturing system includes a dismantling workshop, a preprocessing workshop, and a reassembly workshop. First, the dismantling workshop disassembles the used products into multiple parts; then, the preprocessing workshop reprocesses these parts; finally, the reassembly workshop reassembles these parts i...
