Embodiment

[0034] A balance design method of incomplete dismantling line for multi-person co-station for processing mixed waste products, comprising the following steps:

[0035] S1. A mathematical model is established with the goal of minimum workstation takt time, disassembly cost, demand index, and hazard index. The objective function of the mathematical model is as follows:

[0036] min CT (1)

[0037]

[0038]

[0039]

[0040] Among them, U is the total task set of all products, i, j is the task number, i, j∈U; s is the workstation number s∈S; w is the worker number, w∈W; is the start time of dismantling task i, if i is the first task in the hands of workers in workstation s, then t iw is the dismantling processing time for worker w to perform task i after considering the recycling status of product parts and worker skill differences; dc i is the disassembly cost per unit time to perform task i; oc s running cost per unit time for workstation s; hp w is the hourly ...

Abstract

The invention discloses a multi-person co-station incomplete disassembly line balance design method for processing mixed waste products. Boundary constraint conditions and dismantling balance design model of incomplete dismantling line characteristics of multiple people standing together; the proposed INSGA‑II algorithm is used to solve the dismantling balance design model to obtain the optimal dismantling scheme. The disassembly line balance design model and the INSGA-II algorithm of the present invention are suitable for the optimization of disassembly schemes for mixed products, and extend the traditional complete disassembly of a single product to incomplete disassembly of mixed multi-products, improving the disassembly efficiency.

Description

technical field [0001] The invention relates to the technical field of balance design of dismantling systems, in particular to a balance design method of incomplete dismantling lines for multi-person co-station for processing mixed waste products. Background technique [0002] With the ever-accelerating update speed of smart products and the gradual changes in people's consumption habits, a large number of waste mechanical and electrical products are constantly being produced. Usually waste mechanical and electrical products contain sub-functional components and recyclable raw materials, but also contain harmful substances that pollute the environment. For example, in electric vehicles, wheel hubs, body-in-white, and steering systems are recyclable and valuable components, while power battery packs, polyester materials, and polyoxymethylene materials are substances that are harmful to the environment. Unreasonable disposal of these waste mechanical and electrical products w...
