Abstract: To solve the problems of the high energy consumption and emissions during the forging activities, an energy conservation-oriented multi-stage free forging production scheduling model was put forward. After comprehensively consider the minimization of processing maximum delay, emissions and energy consumption as the objectives of free forging production scheduling, a multi-stage free forging production scheduling model was proposed, which was consisted of three scheduling models with different goals, there were working hours oriented target model, working hours constraint emissions oriented target model, and working hours and emissions constraint energy consumption oriented target model, respectively. An optimal energy conservation-oriented free forging production scheduling method could be obtained by using Heuristic algorithm and Hungarian algorithm. A real-world example illustrated the feasibility and effectiveness of the proposed model.
