In order to effectively improve the production efficiency of assembled channels, accelerate the mold turnover and reduce the production costs. Based on the limited number of steam curing rooms in the assembled channel production line, an optimized production scheduling model of assembled channels with minimum production cycle as the goal was established, and an improved genetic algorithm was designed to solve the model. Taking the channel production line of Xinjiang Shihezi Jintudi Cement Products Factory as an example, the feasibility of the production model was verified, and the stability and effectiveness of the improved genetic algorithm are verified by comparing the traditional sequential production scheduling with the optimized production scheduling with the improved genetic algorithm. The results show that the optimized production scheduling of assembled channels based on the improved genetic algorithm can effectively reduce the production cycle of assembled channels, improve the production efficiency, to achieve the purpose of reducing the production costs and improving the core competitiveness of the enterprise.
