Embodiment

[0074] The invention adopts MATLAB to realize the proposed novel algorithm as an executable program. A test problem is verified. There are 10 tasks in this problem. The task sequence constraint relationship is as follows: figure 1 As shown, the number inside the circle indicates the task number, the upper left corner outside the circle indicates the disassembly direction of the part, the lower left corner indicates the demand for the part, the upper right corner indicates the disassembly time of the part, and the lower right corner indicates the hazard attribute of the part. Set the number of particles to 30, the takt time to 40, the maximum number of iterations to 30, and set the parameter w of the algorithm max =0.9, w min =0.4, C 1 =2,C 2 =2, NG=20, when the program solves the calculation example, it first reads the part sequence constraint relationship of the tested problem, the part disassembly time, hazard, demand and disassembly direction information from the noteboo...

Abstract

The invention discloses a balance control method of a multi-objective disassembly line. The method is characterized by planning a complex disassembly line in a reasonable time, and proposing a relatively optimal solution. The solution comprises division of work stations, arrangement of tasks in the work stations and beats of the assembly line. According to the invention, under the premise of meeting precedence relations and beats constraints, five aspects of the assembly line are collaboratively considered: (1) minimizing number of work stations, that is, minimizing total idle time; (2) equalizing the idle time of each work station as much as possible, that is, balancing time of each work station; (3) removing harmful parts as soon as possible; (4) removing high demand parts as soon as possible; and (5) minimizing change of disassembly direction. The method is close to disassembly environment in actual production, and therefore, the balance design planning and reasonable control of the disassembly line are realized, thereby improving the efficiency of the disassembling line, and optimizing conditions of an actual production and manufacturing system. The method can be applied to modeling and analyzing software of a manufacturing system, management and control module of a computer integrated manufacturing system and actual control.

Description

Technical field: [0001] The invention belongs to the technical field of flexible production line design and control, and in particular relates to a multi-objective dismantling line balance technology. Background technique: [0002] Entering the 21st century, while enjoying the fruits of rapid economic growth, resource and environmental issues have become important problems faced by all mankind. This has also promoted the introduction of new and more stringent environmental legislation in various countries, coupled with the improvement of public environmental awareness, and the implementation of the extended producer responsibility system. More and more manufacturers have begun to pay attention to recycling and recycling. Manufacture of waste demolished items. At the same time, attracted by the economic benefits brought about by it, it also drives more manufacturers to invest in another level. [0003] Product recycling realizes the recovery of materials and the regeneratio...
