Abstract
Taking the assembly line of an automobile engine production plant as an example,due to the company's increasingly diversified product layout,in order to solve the problems of unbalanced load between workstations and insufficient production capacity before and after the introduction of new products,single line balance rate and mixed flow line balance rate mathematical models are successively adopted,combining multiple constraints such as process sequence and production line layout,with the goal of eliminating bottlenecks of different products,balancing loads between workstations,and reducing product waiting times,using methods such as job measurement,method research,and improvement,which successfully achieves an increase in the single-line balance rate of mainstream model lines from 69% to 81% in 2022,and in 2023,achieves the mixed flow line balance rate increase of the multi-variety products from15.7% to41.76%,the mixed-line production efficiency increase by 16%,and the production capacity improvement of new products meeting the demand of 30 units per hour,effectively improving the production capacity of the assembly line.The results show that,compared with the single line balance rate,the optimization of the mixed flow line balance rate can more comprehensively consider the process balance between different products,and effectively improve the company's mixed line production capacity.关键词
