Embodiment 1

[0147] The printer to be disassembled consists of 55 disassembly tasks (n=55). For the priority order of disassembly tasks, see Figure 9 , the disassembly information of the disassembly task is shown in Table 1. The disassembly information includes the disassembly time (unit is s), the required quantity (unit is piece), and the disassembly direction (1 means left side disassembly, 2 means right side disassembly, 3 means left and right can be carried out disassembly) and hazard index (0 means no hazard, 1 means hazard).

Abstract

The invention discloses a bilateral disassembly line setting method considering station constraints and energy consumption. The method comprises the following steps: (1) constructing a mathematical model taking minimization of the number of workstations, idle indexes, hazard indexes and energy consumption indexes as targets; (2) initializing a population, setting an external file, comparing a target function value of the initial population through Pareto, and outputting a Pareto optimal solution to the external file; (3) updating the population by adopting a differential random strategy and adifferential evolution strategy; (4) performing Pareto comparison on a mixed population consisting of the updated population and the external archives, and updating the external archives and the population; (5) repeating the steps (3)-(4) according to the set number of times; and (6) outputting a Pareto optimal solution in the external file as a disassembly task allocation scheme. According to themethod, the population is updated by adopting the differential random strategy and the differential evolution strategy, so that the diversity of the solution is ensured, the calculation is preventedfrom falling into local optimum, the optimal solution can be quickly found, and a quick convergence effect is achieved.

Description

technical field [0001] The present invention relates to the technical field of product disassembly, in particular, to a method for setting up a bilateral disassembly line that considers station constraints and energy consumption. Background technique [0002] The traditional dismantling lines are mostly unilateral and U-shaped. For components that are constrained by a specific working direction, the traditional dismantling method will seriously reduce the disassembly efficiency due to frequent switching of the disassembly direction. The use of bilateral disassembly can effectively reduce the conversion of disassembly directions, reduce production costs, and improve production efficiency. Different from the unilateral dismantling line, the workstations of the bilateral dismantling line are arranged along the two sides of the conveyor, and every two parallel workstations form a combined workstation (it can also be described as a combined workstation including two parallel work...
