With the increasing popularity of green manufacturing concepts, achieving reduced energy consumption and shorter delivery times while maintaining production efficiency has become a major challenge for the manufacturing sector. This study focuses on the mul-ti-objective workshop of Z Company. Based on the multi-objective workshop scheduling theory that considers energy consumption and delivery time, a multi-objective optimization model incorporat-ing these factors is constructed. An improved immune genetic algorithm is designed to solve the established model. A comparative analysis between the experimental results of the algorithm and actual outcomes reveals that the multi-objective workshop scheduling scheme, which takes into ac-count energy consumption and delivery time, provides valuable guidance in practical production. This verifies the effectiveness and feasibility of the algorithm. This research not only provides theo-retical support for improving the production efficiency of Z Company but also contributes new ideas and methods for achieving green and sustainable development in the manufacturing industry.展开更多
