Abstract: This paper focuses on the optimization of production line balancing in mixed-model production, with benchmark process templates as the core research object. In response to the current situation of small-batch and multi-variety production, the necessity and complexity of mixed-model production are analyzed in depth, and balancing strategies for mixed-model production under two typical scenarios of similar and significantly different production rhythms are proposed. By constructing a mathematical model based on benchmark process templates and exploring its principles, the practical application of optimizing mixed-model production balancing, improving production efficiency, and reducing production costs is demonstrated through case studies. The results show that benchmark process templates can effectively integrate the production processes of different products, reduce process waste, and enhance the flexibility and adaptability of the production line, providing theoretical support and practical guidance for enterprises to achieve efficient operation under the mixed-model production mode.
