Embodiment

[0068] The invention adopts MATLAB to realize the proposed novel algorithm as an executable program. A test problem is verified. There are 35 tasks in this problem. The task sequence constraints are as follows: figure 2 As shown, the number inside the circle represents the task sequence number, and the number outside the circle represents the operation time of the task. Set the number of particles to 10, the takt time to 61, the number of iterations to 50, and set the parameters of the algorithm w=0.85, C 1 = 0.7, C 2 =0.5, NG=10, when the program solves the calculation example, it first reads the task sequence constraint relationship of the tested problem and the processing time information of the task from the notebook, and generates the task sequence constraint relationship matrix and the operation time vector of the task. In the task sequence constraint relationship matrix, the recorded data is P ij value, if P ij If it is 1, it means that task i is the immediately pr...

Abstract

The invention discloses a balancing control method for a single-sided assembly line. Production conditions are optimally controlled on the single-sided assembly line which has a first kind of balancing problems to balance loads of each station, and a reasonable and optimal scheme is provided for the complicated problems about planning and improvement of a production line within reasonable time. The scheme comprises dividing of work stations, arrangement of tasks in the work stations and computation of a cycle of the production line. The method has the advantages that: on the premise that the cycle of an assembly line is set, the number of the work stations is decreased, and the balance rate of the assembly line is optimized; by taking an assembly line balance rate index as an optimization target, the problems about balancing design planning and reasonable control of the assembly line can be effectively solved; and the method can be applied to manufacturing system modeling and analysis software, a computer integrated manufacturing system management and control module and an actual control module.

Description

Technical field: [0001] The invention belongs to the technical field of automatic production lines, in particular to the balancing technology of a single-side production line and a single-side assembly line. Background technique: [0002] Assembly Line Balancing Problem (Assembly Line Balancing Problem, ALBP) is an important problem faced by manufacturing enterprises. Improving the utilization rate of facilities in the production assembly line can directly improve production efficiency and will have a direct impact on the economic benefits of the enterprise. Since ALBP is a typical NP-type combinatorial optimization problem, the complexity of solving the problem explodes exponentially with the increase of the number of tasks. Therefore, it is important to develop algorithms that can solve large-scale problems in a reasonable time. [0003] In the US patent (name: Balancing workloads in an electronics assembly factory, patent number 6829514), Julius et al. proposed a method...
