Problems solved by technology

[0005] Although the research on the DLPB problem has achieved considerable results, the dismantling line balance problem studied in these results mainly considers minimizing the number of workstations, balancing the idle time of each workstation, and removing potentially harmful parts as soon as possible. Carbon emissions are less considered

Abstract

The invention discloses a low-carbon and high-efficiency parallel disassembly line balance optimization method. The method comprises the steps that a parallel disassembly model is established, and anoptimization model of parallel disassembly line balance is established. The optimization goal is to reduce carbon emission and reduce disassembly time, and belongs to multi-objective optimization; onthis basis, the parallel disassembly model is established, then practical constraints of a disassembly balance problem are comprehensively considered, the high-efficiency and low-carbon optimization method of a disassembly sequence is established, when the optimization problem is solved, a weight method is used for converting a multi-target problem into a single-target problem, finally a genetic algorithm is used for solving the disassembly line balance problem, it can be seen from a convergence graph that the genetic algorithm has a high convergence speed, and the model has a certain optimization effect on the disassembly time.

Description

technical field [0001] The invention belongs to the technical field of flexible production line design and control, and relates to a low-carbon and high-efficiency parallel disassembly line balance optimization method. Background technique [0002] With the process of world industrialization, while people's living standards and quality of life have been greatly improved, hundreds of millions of tons of domestic and industrial waste have also been generated. As of the end of 2017, the total annual recovery of ten categories of renewable resources including scrap iron and steel, waste electrical and electronic products, and scrapped cars in my country was about 282 million tons. In order to better recycle and utilize renewable resources, countries have successively introduced stricter laws and regulations. [0003] The whole process of remanufacturing includes recycling, dismantling, sorting, cleaning, identification, remanufacturing, assembly and testing of waste equipment. ...
