Abstract

The invention discloses a method for setting a parallel incomplete disassembly line for disassembling waste products. The method comprises the following steps of: (1) constructing a mathematical modelaiming at minimizing the disassembly depth, the number of workstations, the idle time balance index of the workstations and the number of disassembly resources; (2) generating an initial population;(3) obtaining neighborhood individuals of the initial population; (4) comparing the target function value of a mixed group composed of the neighborhood individuals and the population individuals through Pareto, updating the population, and outputting a Pareto optimal solution to an external file; (5) performing simulated annealing operation on the population updated in the step (4) to obtain a newpopulation; (6) comparing a target function value of a mixed group consisting of the group subjected to simulated annealing operation and an external file by adopting Pareto, and outputting a Paretooptimal solution to the external file; (7) repeating the steps (3)-(6) according to the set number of times; and (8) outputting a Pareto optimal solution in the external file as a disassembly task allocation scheme. The method is easy to implement and high in search capacity.

Description

Technical field [0001] The present invention relates to the technical field of product disassembly, and in particular to a method for setting up a parallel incomplete disassembly line for disassembling waste products. Background technique [0002] With the continuous development of the social economy, the people’s material living standards are constantly improving, and the speed of upgrading various products is also increasing. According to statistics, my country’s theoretically scrapped household appliances reach 100 to 120 million units each year, and The number continues to grow at an average annual rate of 20%. If these waste products are directly buried or incinerated, it will inevitably have a bad impact on the environment and a waste of resources. In order to minimize the environmental pollution caused by waste products and fully extract the reusable resources contained in waste products, it is necessary to recycle and remanufacture waste products. Disassembly is a key pa...
