Abstract: With the increasing uncertainty and customisation of our manufacturing market demand in recent years, the wide variety and small batoh production approach has gradually been replaced by mode of production, so companies must be able to respond quickly to market demand, therefore, rapid production change has become an important part of the manufacturing process. Based on the analysis of HD's automated line change process, this paper optimizes, improves and standardizes the process using image analysis, Brainstorming, ECRS and other related industrial engineering ideas and methods, shorten the production change time of line body, and finally realize the cost reduction and efficiency increase of the enterprise, which reflects the great potential and value of the application of industrial engineering technology in the machinery manufacturing industry.

Key words: Industrial engineering; Lean production; Image analysis; Rapid production change; Improvement case
